6.12 The equation T= Q(V2- V1) indicates the thrust output of an engine can be increased by either increasing the mass airflow or ________________? 13.18 During a turn in an aircraft, the vertical component of lift is also known as______________. You should be able to come up with the answer in less time than it took you to read this! In reality, the landing distance is pretty much determined by the stall speed (the plane must touch down at a speed higher than stall speed, often about 1.2 VStall) and the glide slope (where obstacle clearance is part of the defined target distance). 5.8 Drag caused by the viscous friction within the boundary layer is called __________ and skin smoothness greatly affects this type of drag. It's going to be harder to get a precise answer this way, and it may end up taking you longer. Power required is drag multiplied by TAS. 8.24 Though a turboprop produces power and thrust, the amount of thrust produced directly by the engine is only about what percentage of the total? 12.19 Wind shear is confined only to what altitudes? One that is fairly easy to deal with is turning. 11.18 Which factor affects the calculation of landing performance for a typical aircraft? and B = (g/W) [ S(CD CLg) + a] . 12.21 When taking off in a microburst, a pilot should be aware of what change in performance when going from a headwind to a tailwind? Figure 9.3: James F. Marchman (2004). Effects of a Desired Climb Rate on Aircraft Design Space. CC BY 4.0. The constraint analysis may be performed several times, looking at the effects of varying things like wing aspect ratio on the outcome. 3.2 The main variable(s) in the geometry of an airfoil are: 3.3 The angle between the relative wind and the chord line of an airfoil is the, 3.4 For a symmetrical airfoil, at 0o AOA, air passing over the wing results in, An equal increase in velocity over the top and bottom of the wing. Connect and share knowledge within a single location that is structured and easy to search. In a propeller driven aircraft, L/D max is often associated with V Y - best rate of climb speed. One finds the desired takeoff distance in feet on the vertical axis and projects over to the plot for the type of aircraft desired, then drops a vertical line to the TOP axis to find a value for that term. Calculate (or find in Table 2.1) the Temperature Ratio: 2.11 An airplane is operating from an airfield that has a barometric pressure of 28.86 in. 11.3 How does a weight increase affect landing performance? On the other hand, the climb curve should be plotted for optimum conditions; i.e., maximum rate of climb (minimum power required conditions for a prop aircraft) since that is the design target in climb. Looking again at the aircraft in Homework 8 with some additional information: 1. Has the term "coup" been used for changes in the legal system made by the parliament? Power required to overcome induced drag varies, Power required to overcome parasite drag varies, Maximum rate of climb for a propeller airplane occurs. Car tires can be designed to have high traction in mud and snow or to give great mileage at highway speeds but any attempt to design an all weather touring tire will result in a compromise with less traction than a mud and snow tire and poorer performance at high speeds than the high speed highway tire design. Finding this value of drag would set the thrust we need for cruise. I've read the other thread about the throttles, reversing, and feathering. 7.16 With a typical drag curve, how many times does the thrust available line intersect the thrust required curve? If the coefficient of friction is 0.8, find the braking force Fb on the airplane. 10.12 The following items all affect takeoff performance except __________. 6.11 The equation T= Q(V2- V1) expresses Newton's ______ law. Making statements based on opinion; back them up with references or personal experience. We might find, for example, that by accepting an additional 500 feet in our takeoff ground run we can get by with a significantly smaller engine. But, in a jet, you'll often fly close to your best range speed. 2.18 Density altitude is found by correcting _______________ for _______________. This is because, The increase is mostly due to parasite Pr, 9.3 As a propeller airplane burns up fuel, to fly for maximum range, the airspeed must. In other words if you vary the point of contact between the line and the curve slightly, the resulting climb angle will barely change at all. 9.9 For a power-producing aircraft, an increase in weight results in a decrease of Vmax. c. How did you infer those two answers from a pie chart? Legal. If our desire is to look at an optimum range we might want to find the ratio of lift to drag that will maximize range (for example, for a propeller driven plane Rmax occurs with flight at [L/D]max or at minimum drag conditions). Find the Rate of Climb. And a big wing area gives us high drag along with high lift. Hg and a runway temperature of 20C. 7.18 Increasing the weight of a thrust-producing aircraft moves all points on the thrust-required curve ____________. What effect does an increase in AOA have on the laminar characteristics of a laminar flow airfoil? Find the Drift Angle. In essence this is a pretty powerful relationship and it can be used to analyze many flight situations and to determine an airplanes performance capabilities. Highest point on the curve yields maximum climb rate (obviously). How would a three-hour time exposure photograph of stars in the northern sky appear if Earth did not rotate? And they may be different still in climb. Sometimes this is called a "service ceiling" for jet powered aircraft. What is the wavelength of this light as it travels through water (nwater=1.33)\left(n_{\text {water }}=1.33\right)(nwater=1.33) ? 10.4 What effect does a headwind have on takeoff performance? It says that we need a higher thrust-to-weight ratio to climb than to fly straight and level. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Here we should note that the space to the right of the dashed line for stall is out of bounds since to fly here would require a higher maximum lift coefficient. How can I find the maximum climb angle of a propeller driven aircraft from a graph of vertical velocity against airspeed? In fact, the equations used to find the maximum range for either a jet or a prop aircraft assume flight at very low speeds, speeds that one would never really use in cruise unless desperate to extend range in some emergency situation. Best Rate of Climb 1.10 An aircraft is in a steady climb, at an airspeed of 100 knots, and the flight path makes a 10 angle with the horizontal. 6.24 For a thrust-producing aircraft, the maximum climb angle occurs where the maximum _________ exists. Using the PA-PRcurves in 2-3 for a propeller airplane find: _______ a. When plotting the cruise curve in a constraint analysis plot it should be assumed that the aircraft is cruising at a desired normal cruise speed, which will be neither the top speed at that altitude nor the speed for maximum range. where A = g[(T0/W) ]. 2.22 _____________________ results when the CAS has been corrected for compressibility effects. 13.14 (Reference Figure 14.10) What airspeed must an aircraft maintain at 50 degrees of bank to achieve 10,000 feet radius of turn? 11.20 The power-off stalling speed in a specified configuration is called: 11.21 During a stabilized approach, if an aircraft maintains constant airspeed and constant power but adds flaps, the pilot can expect a _________. 7.17 Changing the weight of an aircraft changes the ______________ much more than the ___________. It is called: AERO 1020 Final Review: All Past Test Q's/A's, Materials Science and Engineering: An Introduction, CT Basics 2.0 | Module 1: CT Fundamentals Test, MKT201 700 FULL CHAP-Key 700 Trung sa. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. On the other hand, the climb curve should be plotted for optimum conditions; i.e., maximum rate of climb (minimum power required conditions for a prop aircraft) since that is the design target in climb. Find the range for the C-182 assuming the flight starts at 150 mph and an altitude of 7500 feet and stays at constant angle of attack. 7.13 (Reference Figure 7.2) Using Figure 7.2, find the velocity for maximum endurance for the airplane at 12,000 lbs. pressure altitude / nonstandard temperature conditions. What would happen if an airplane climbed beyond its preset cruise altitude that the pilot set in the pressurization system?

But even in high-performance aircraft capable of steep climb angles where this is no longer the case, it can be geometrically shown that the steepest climb angle also occurs when the ratio of vertical speed to airspeed is maximized. 4.1 The portion of the boundary layer airflow known as laminar flow is characterized by, Reverses flow direction when stall occurs, 4.3 Adverse pressure gradient on an airfoil is found, c. From the point of minimum pressure to the trailing edge, 4.5 List the two types of stalls that are of interest to the non-jet pilot, 4.10 As thickness of an airfoil is increased, the stall AOA, 4.11 As camber of an airfoil is increased, its CL at any AOA, 4.12 A smaller Reynolds number (less than 0.5 million) indicates, 4.13 A large Reynolds number (greater than 10 million) indicates, 4.14 The thicker the airfoil, ___________________. The formula is ROC in FPM = ExcessHP*33,000*Propeller efficiency divided by All up Mass in LBS. <> 10.21 A _____ increase in weight results in _____ increase in takeoff distance. Note that the thrust ratio above is normally just the ratio of density since it is normally assumed that. Just as an aside, the vertical speed can't be higher than the airspeed, so it's not even. Effect of Aircraft Parameters on Takeoff Distance. CC BY 4.0. The first step in the process is usually to look for what are called comparator aircraft, existing or past aircraft that can meet most or all of our design objectives. Or, if you've re-plotted your graph with the same scale on each axis, and you aren't worried about the difference between airspeed and horizontal speed, you can forgo the trig calculation and just use a protractor to measure the angle between the tangent line and the x axis of your graph of vertical speed versus airspeed. The ones that spring to mind are A/C weight, temperature, and density altitude. 9.4 A lightly loaded propeller airplane will be able to glide ____________ when it is heavily loaded. It should be noted that in plotting curves for cruise and climb a flight speed must be selected for each. 7.22 The value of (L/D)max changes when the gear and flaps are lowered. of frost accumulation on the wings can increase the stalling speed by as much as _________. In cruise where lift = weight and thrust = drag, T/W = 1 / [L/D], meaning that the high value of L/D that is needed for a large range goes hand in hand with a low thrust-to-weight ratio. Interesting airplane; looks like Vy is more than double Vx! stream 3.22 The example of the pressure distribution on a rotating cylinder that explains why a golf ball slices is best described by ______________. 5.17 An airplane with a heavy load _______________ when lightly loaded. 1.16 An airplane weighs 8,000 lbs and is flying at 6,000 ft altitude and an airspeed of 200 fps. 11.17 Headwinds and tailwinds affect the landing distance by the same amount as they affect the takeoff distance. It allows the aircraft to reach takeoff velocity at a lower groundspeed than for a no-wind condition. 2.19 Standard temperature for degrees C is ___________. 13.21 As the weight of an aircraft decreases, the VA. 13.22 ______________ of the total lift is the centripetal force that causes radial acceleration. 12.16 All speeds below the speed for minimum drag are said to be in the _________. Maximum rate of climb for a propeller airplane occurs: a. at L/D max b. at CLmax c. at PRmin d. at (PA-PR) max. Does an airfoil drag coefficient takes parasite drag into account? Again it is common for aircraft design texts to propose approximate or semi-empirical relationships to describe this and those relationships show landing distance to depend only on the wing loading. 11.9 If in descending, gliding flight, a component of ________ acts in the same direction as thrust. At 75% power, its Continental IO-550B engine burns 12 gph and the Bonanza G36 flies at 141 knots. We cant fly straight and level at speeds below the stall speed or above the maximum speed where the drag equals the maximum thrust from the engine. This addition to the plot tells us the obvious in a way. endobj 7.25 To obtain maximum range for a thrust-producing aircraft, as fuel is burned _______________. Measure the distance from the crankshaft to the ground and subtract 9 inches to allow for safe ground clearance. Figure 9.1: James F. Marchman (2004). How is the "active partition" determined when using GPT? Still looking for something? That's the actual angle of the slope of the straight line you drew on the graph. 5.20 The most aerodynamically efficient AOA is found at. An iterative solution may be necessary. 1. 7.20 When a pilot lowers the landing gear, _______________ is increased. Of course when someone metricly assumes that one is both climbing and flying forward in m/s, that must be some airplane! This can be determined from the power performance information studied in the last chapter. So your graph of vertical speed versus airspeed will work just fine for finding the maximum climb angle. wo6eo'}Mkl?@^l8$.$owVF-*: qyCe&D>a+%Xc d/J0GC:rqC'J a. d. If all commercial users agreed to cut their energy usage by 20%, which group would be the biggest user of electrical energy in the United States? Obviously altitude is a factor in plotting these curves. 13.19 The G's required for an aircraft to maintain altitude in a coordinated turn are determined by ____________. where , for example, and .The power available is a function of the propulsion system, the flight velocity, altitude, etc. 6.19 For a turbojet, each pound of drag requires a pound of ____________ to offset it. Power available is thrust multiplied by TAS. (meters/second), Conversion of airspeed to horizontal velocity: The type of aircraft, airspeed, or other factors have no influence on the load factor. 3.13 thru 3.17 Reference Figure 2. We could get a different curve for different cruise speeds and altitudes but at any given combination of these this will tell us all the combinations of thrust-to-weight values and wing loadings that will allow straight and level flight at that altitude and speed. To escape wake turbulence a pilot should avoid, 12.9 Wake turbulence is typically characterized by. It does this by looking at two important ratios, the thrust-to-weight ratio (T/W), the wing loading or ratio of weight-to-planform area (W/S). Under what conditions can the maximum angle of climb be achieved for jet and propeller aircraft? Therefore both approaches must have the same solution: when the ratio of vertical speed to airspeed is maximized, then the ratio of vertical speed to horizontal speed is also maximized. Hence, what we have done through the specific excess power relationship is nothing but a different way to get a familiar result. For the prop aircraft Raymer defines TOP as follows: It should be noted here that it is often common when conducting a constraint analysis for a propeller type aircraft to plot the power-to-weight ratio versus wing loading rather than using the thrust-to-weight ratio. The greatest danger(s) is that. 3.7 The Center of Pressure __________ move with a change in AOA for a symmetrical airfoil, while it ____________ move with a change in AOA for a cambered airfoil. Adapted from Raymer, Daniel P. (1992). 11.14 During a landing in a tricycle gear aircraft, ________ braking is used before _________. A car can be designed to go really fast or to get really good gas mileage, but probably not both. 5. max thickness. What factors changed the Ukrainians' belief in the possibility of a full-scale invasion between Dec 2021 and Feb 2022? If T/W = 1.0 or greater we need no wing. 12.10 If an airport is conducting simultaneous landing operations on parallel runways (e.g. For example, if the hub-to-ground measurement is 45 inches, subtracting 9 inches will leave an effective radius of 36 inches. Once the value of TOP has been found the relationship above is plotted to give a straight line from the origin of the constraint analysis graph. 12.23 An aircraft in which of the following situations is most likely to create the most intense wake turbulence? 12.4 ______________ wings will stall at the wing root first and then progress toward the rest of the wing. 7.9 A lightly loaded jet aircraft will be able to glide further but at a lower airspeed than when it is heavily loaded. Then the solution is the point with the steepest angle from the origin of the graph. -- why? 5.21 Wingtip vortices are formed by higher-pressure air beneath a wing moving into __________ pressure air above the wing. You are correct that Vy will give you the max RoC. Aircraft Design: A Conceptual Approach, AIAA, Washington, DC. In understanding what this really tells us we perhaps need to step back and look at the same situation another way. In an earlier chapter on climb and glide we looked at something called specific excess power and defined it as: Ps = [Pavail Preq] / W = [(T D)V] / W. We may, hopefully, remember using this relationship to find the rate of climb but we may not recall that it was only the correct rate of climb in a special case, where speed (V) was constant; i.e., the static rate of climb: If we go back to that earlier chapter we will find that in a more general relationship we had: Ps = [Pavail Preq] / W = [(T D)V] / W = [dh/dt] + (V/g)(dV/dt). Rate of Climb formula. For a turbojet aircraft with a drag equation described by: C D = C D 0 + K C L 2. with C D 0 = 0.012, and K = 0.035, a wing area of 70 m 2, a weight of 120.000 kN, and a maximum lift coefficient of 1.900, capable of producing a thrust of 120.000 kN at a given altitude, the climb rate and angles can be taken from the . 9.5 To obtain maximum glide distance, a heavily loaded airplane must be flown at a higher airspeed than if it is lightly loaded, 9.6 The increase in the Pr curves for a weight increase is greater at low speeds than at high speeds because the increase in. It only takes a minute to sign up. 3.1 The mean camber line can be defined as: A line drawn halfway between the upper surface and the lower surface. The question is; is there some way to analyze all of these at the same time and come to a decision about optimum or reasonable compromise values of weight, wing area, and engine thrust without having to go through iteration after iteration? This data can give us a place to start by suggesting starting values of things like takeoff weight, wing area, aspect ratio, etc. The analysis may suggest that some of the constraints (i.e., the performance targets) need to be relaxed. The maximum angle of climb would occur where there exists the greatest difference between thrust available and thrust required; i.e., for the propeller-powered airplane, the maximum excess thrust and angle of climb will occur at some speed just above the stall speed. 11.23 If an aircraft traveling down a runway has a tire pressure of 200 psi and no other information is available, the approximate speed to which total dynamic hydroplaning may occur is __________. 1.25 The Law of Conservation of Energy states that: 2.1 Static air pressure is simply the weight per unit area of the air above the level under consideration. We would then have to decide which of these three requirements was most important and which was least important and then start varying design parameters in an iterative manner until we got all three objectives to result in the same weight, wing area, and engine thrust. These two ratios are tied together in aircraft performance through the same power relationship that we looked at when we first examined climb and glide. If the engine is capable of producing more power than the power required, that excess power can be used to make the plane accelerate to a faster speed (increasing kinetic energy) or to climb to a higher altitude (increasing potential energy), or to give some combination of both. Lets look at how the equation can be rearranged to help us examine the performance needs in various types of flight. Nonetheless, we can see that three parameters; thrust, weight, and wing area, are important factors to consider in takeoff. 8.23 For a power producer, unaccelerated maximum velocity will occur at the intersection of the full power-available curve and the ________________. The size of the turn circle as determined by the angle of bank and airspeed, The number of degrees per second that the aircraft is turning as determined by the angle of bank and airspeed, 13.12 (Reference Figure 14.10) An aircraft traveling at 150 knots and 45of bank will have a radius of turn of. 3.2 An aircraft in a coordinated, level banked turn. 1.12 Solve for left and right moment arm and fulcrum force against the seesaw (respectively) (See Figure 1_Test 1): 1.13 An airplane weighs 8,000 lb. 121.65 knots 1.9 An aircraft is traveling west at an airspeed of 120 knots and is experiencing a crosswind of 20 knots from the north (90). 10.20 One of the dangers of overrotation is ________________. *de`b h74W.|RZOeIH/Zp %''S^zk4SZ"@uY]2s?Dd8o"gVh|_Lbz!]HR [f&:nIG}#Zg#x>IjL:]PR`cQ%$(|V17?/M/r!1& z7wM#-Lw]Ita8U J%5manh&+=RRi1%'Z$w _Lt)m#3g -yT9yzK%hmsPdX]VWx}azb#a4syc-#gQo xY!rK$5x ;W!II-nsZ5! Best angle of climb (BAOC) airspeed for an airplane is the speed at which the maximum excess thrust is available. From the spreadsheet, this climb angle can be read. Cosine of Climb Angle x Airspeed = Horizontal Velocity. c. By how many fringes will this water layer shift the interference pattern? What is the arrow notation in the start of some lines in Vim? Maximum rate of climb for a propeller airplane occurs At (Pa-Pr)max True or false The lowest point on the Pr curve is (L/D)max. 6.22 Vx is also known as _____________________. Constraint analysis is essentially a way to look at aircraft weight, wing area, and engine thrust for various phases of flight and come to a decision about meaningful starting values of all three parameters for a given set of design objectives. The Beechcraft G36 Bonanza was released in 2006 and costs between $950,000 and $1,300,000, new. 2.6 The corrections that must be made to indicated airspeed (IAS) to obtain calibrated airspeed (CAS) are: 2.7 The correction from equivalent airspeed (EAS) to true airspeed (TAS) is dependent on: 2.8 An airplane is operating from an airfield that has a barometric pressure of 28.86 in. 5.25 Parasite drag can be said to ____________. 2.13 Using Table 2.1 and the appropriate equation, calculate the dynamic pressure, q, at 7,000 ft density altitude and 140 knots TAS. Of course, it helps to do this in metric units. And this can be written [W/S] = Vstall2CLmax, On the plot above this would be a vertical line, looking something like this. 10.5 What effect does a tailwind have on takeoff performance? 11.24 If an aircraft traveling down a runway has a tire pressure of 50 psi and no other information is available, the approximate speed to which total dynamic hydroplaning may occur is __________. 9.15 If an aircraft with a clean configuration deploys gear and approach flaps, yet desires to maintain the same indicated speed as before the gear and flaps were deployed, which of the following has to be increased? For climb at constant speed dV/dt = 0 and our equation becomes, T/W = (qCD0)/(W/S) + (kn2/q)(W/S) + (1/V)dh/dt. 8.14 A propeller where the pitch setting can only be adjusted on the ground and requires that the engine be stopped is known as: 8.15 An engine where the fuel-air mixture is forced into the cylinders by natural atmospheric pressure upon opening of the inlet valves. How many "extra" wavelengths does the light now travel in this arm? Note that this equation does not represent an actual aircraft polar; it refers to the initial climb-out after takeoff. How sensitive is the maximum range for the Cessna 182 to aspect ratio and the Oswald efficiency factor, i.e. 3.25 The rudder controls movement around the ________________ axis. 13.15 (Reference Figure 14.10) How many degrees of bank are required for a standard rate turn (3 degrees per second) at 420 knots? 5.23 For a given aircraft wing, if the wing span increases and the average chord remains the same, the aspect ratio will __________. See also. 8.13 A propeller where the blade pitch setting is either hydraulically or electrically controlled. We know that in cruise since lift must equal weight, we can select a design value of cruise lift coefficient (commonly around 0.2 to 0.3) and a desired cruise speed and altitude and solve for the needed wing area. Best Rate of Climb This is a nice concise answer with a nice graphic. Figure 9.7: Effect of R & e Variation on max Range Cessna 182. AERO 1020 Final Review: All Past Test Q's/A's, Genetics Lecture 13 - DNA Chem and Replication. If we assume a coordinated turn we find that once again the last two terms in the constraint analysis relationship go to zero since a coordinated turn is made at constant altitude and airspeed. If there is an increase in air pressure, it will: Affect air density by increasing the density. Figure 9.7: Kindred Grey (2021). to the wing planform shape? Excess power is power available minus power required. To include drag due to engine failure at low thrust/ weight ratios, E may be reduced by approx-imately 4% for wing-mounted engines and 2% for engines mounted on either side of the fuselage tail. TSL / WTO = [(Walt/WTO) / (Talt/TSL)] {[q/(Walt/WSL)](CD0)/(WTO/S). 1.19 An aircraft weighs 12,000 lbs. 8.5 Propeller aircraft get the highest angle of climb at (L/D)max. 13.23 High bank angles and slower airspeeds produce ________ turn radii. 4.23 Stall is airflow separation of the boundary layer from the lifting surface. These are then plotted to find optimum values of wing loading and thrust-to-weight ratio. A head wind is encountered. T/W = (qCD0)/(W/S) + (kn2/q)(W/S) + (1/V)dh/dt + (1/g)dV/dt . <> As one of my students once put it, the thrust-to-weight ratio (T/W) is a measure of how much of a rocket your plane is. 5.6 Which of the following is a type of parasite drag? In other words, only when velocity (V) is constant is this relationship strictly equal to the rate of climb. 2.2 For temperatures to be used in calculating the effects on performance, the appropriate absolute scale must be used. 13. 2.5 Bernoulli's equation for subsonic flow states that: If the velocity of an airstream within a tube is increased, the static pressure of the air decreases. How does a fixed-pitch propeller changes the blade's angle of attack? To land in a short distance we might want to also design a plane with a large wing and high maximum lift coefficient but now the thrust isnt as important as the amount of braking friction available unless it is reverse thrust that we are talking about. Raymer proposed the relationship below: Sa = 1000 for an airliner with a 3 degree glideslope, 600 for a general aviation type power off approach. b. 15. 12.24 For an aircraft to spin, both wings have to be stalled. The takeoff equation seen in an earlier chapter is somewhat complex because takeoff ground distances depend on many things, from drag coefficients to ground friction. 3.21 The point on the chord line where the aerodynamic force acts is the _____________. .
