AERO 1020 Final Review: All Past Test Q's/A's, Genetics Lecture 13 - DNA Chem and Replication. Turboprop aircraft are classified as power producers because: Helicopters have another power requirement over fixed wing propeller airplanes. One way to find the maximum ratio of y to x on any graph of y versus x is to extend the axes of the graph to include the origin (0,0) and just run a line from the origin to any point on the curve and find the point on the curve where the slope of this line is the steepest, just as was done in these related answers: What is the typical climb angle A car can be designed to go really fast or to get really good gas mileage, but probably not both. 6.21 The lowest values of ct occur between 95 and 100% rpm. Boldmethod. 5.25 Parasite drag can be said to ____________. Effect of Desired Takeoff Characteristics on Aircraft Design Space. CC BY 4.0. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The cruise based calculations mentioned above would give us valuable design information for our airplane based on a desired cruise speed and altitude for a design weight and would tell us the wing area and thrust needed for that cruise condition and the thrust needed to cruise at a desired maximum speed. In many aircraft the difference between horizontal speed and airspeed will be trivial. 12.22 According to the textbook, one study showed that 0.1 in. where , for example, and .The power available is a function of the propulsion system, the flight velocity, altitude, etc. 6.14 The minimum fuel flow for a jet aircraft occurs at the minimum thrust required, otherwise known as ______________. Fortunately, the answer is yes. The aircraft will experience structural damage or failure. -- why? Highest point on the curve yields maximum climb rate (obviously). Modern propellers on larger aircraft would always be equipped with automatic feathering provisions. For a propeller-powered airplane, at an airspeed just above stall speed and below L/D MAX. Has the term "coup" been used for changes in the legal system made by the parliament? This is not a condition which we have studied earlier but we can get some idea of where this occurs by looking at the plot of drag versus velocity for an aircraft. Would the reflected sun's radiation melt ice in LEO? One of these items is ________________. "Of course, it helps to do this in metric units." This can be done fairly easily by going back to the constraint analysis equations and substituting P/V everywhere that a thrust term appears. 12.11 What two things are necessary for an aircraft to enter a spin? Do you think this is a reasonable speed for flight? @quietflyer It does not matter as long as the units are the same. While you are at it, just the sake of curiosity you might want to also calculate the arctangent of (vertical speed / airspeed) for the same data point. This is a nice concise answer with a nice graphic. The second is that the takeoff parameter (TOP) defined for propeller aircraft is based on power requirements (specifically, horsepower requirements) rather than thrust. 6.20 Where is (L/D)max located on a Tr curve? 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. 13.7 (Reference Figure 5.4) What will happen to an aircraft that is flown to the right side of the straight vertical line on the right side of the flight envelope? In a Cirrus SR22T, our indicated cruise speed is often 30 to 40 knots faster than V Y with 75% power. It can tell us how much speed we can gain by descending to a lower altitude, converting potential energy to kinetic energy, or how we can perhaps climb above the static ceiling of the aircraft by converting excess speed (kinetic energy) into extra altitude (potential energy). 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. Maximum Rate of Climb for a propeller-driven airplane Since the available power is constant with W, the maximum excess power, RIC occurs at the flight velocity for minimum power required therefore: An equation for the maximum rate of climb is obtained by substituting V(R/C)max For rate of climb, the maximum rate would occur where there exists the greatest difference between power available and power required (Fig. 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. 11.14 During a landing in a tricycle gear aircraft, ________ braking is used before _________. 8.25 When leveling off at cruise altitude after a climb in an aircraft with a fixed-pitch propeller, as the forward speed of the aircraft increases the blade angle of attack __________. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. It's going to be harder to get a precise answer this way, and it may end up taking you longer. 6.23 Vy is also known as __________________. . Substituting this for drag in the equation and dividing the entire equation by V we can get: (T/W) = [(CD0 + kCL2) V2S) /W] + (1/V)dh/dt + (1/g)(dV/dt). The number of distinct words in a sentence. Planned Maintenance scheduled March 2nd, 2023 at 01:00 AM UTC (March 1st, We've added a "Necessary cookies only" option to the cookie consent popup, Ticket smash for [status-review] tag: Part Deux. (As a point of trivia, it looks like if the horizontal units on your graph are knots and the vertical units are feet/min, then the angle computed with the arcsine is about 4% larger, or about 0.6 degrees larger, than the angle computed with the arctangent.). If the two values are almost the same, that indicates that the airspeed and horizontal speed are so close as to be practically interchangeable, at least at that point on the performance curve. What is the typical climb angle (versus the ground) of a single engine piston plane? Classify the monosaccharide structure in Problem 18.71 as an \alpha-anomer or a \beta-anomer. At maximum weight it has a VY of 75 kn (139 km/h) indicated airspeed [4] providing a rate of climb of 721 ft/min (3.66 m/s). c. By how many fringes will this water layer shift the interference pattern? Variometer [ edit] Within all this we could look at the effects of aspect ratio and Oswalds efficiency factor to find how wing planform shape will affect our results. The more efficient a plane is in things like cruise the lower its value of T/W. **tHS-8_0hDRIX2^KK0+z# Y]Q2I TBz ,"JyTyXFv4nm.P t #&'++"T[(2;Ggg~y! As fuel is burned the pilot must. An iterative solution may be necessary. 10.13 A higher density altitude on takeoff does not affect which one of the following aircraft below its critical altitude? This ratio is a measure of aerodynamic efficiency as well as a measure of the way the structure is designed. The design process usually begins with a set of design objectives such as these we have examined, a desired range, payload weight, rate of climb, takeoff and landing distances, top speed, ceiling, etc. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. 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). Note here that the weight in the equation is the landing weight but that in calculating this landing distance for design purposes the takeoff weight is usually used for general aviation aircraft and trainers and is assumed to be 0.85 times the takeoff weight for jet transports. the point of minimum pressure is moved backward. To answer this, plot range versus aspect ratio using e.= 0.8 and varying AR from 4 through 10, and plot range versus e for an aspect ratio of 7.366 with e varying from 0.6 through 1.0. Rate of climb at maximum power for a small aircraft is typically specified in its normal operating procedures but for large jet airliners it is usually mentioned in emergency operating procedures. Best Rate of Climb 12.6 The best way to control airspeed is with the ___________, while the best way to control altitude/descent rate is with the ____________. 1.19 An aircraft weighs 12,000 lbs. 5. max thickness. Just as an aside, the vertical speed can't be higher than the airspeed, so it's not even. Time to Climb Between Two Altitudes How would a three-hour time exposure photograph of stars in the northern sky appear if Earth did not rotate? The question with the design of an airplane as with a car or a tire, is how do we arrive at the best compromise that will result in a good all around design while still being better than average in one or two desired areas? We can use the above relationship to make plots of the thrust-to-weight ratio versus the wing loading for various types of flight. endobj 1. You don't have to know all three of these values-- any two are sufficient, and in this case you'll know the airspeed and the vertical speed. Of course, it helps to do this in metric units. pressure altitude / nonstandard temperature conditions. See Page 1. 6.24 For a thrust-producing aircraft, the maximum climb angle occurs where the maximum _________ exists. 8.16 A gas turbine engine that uses most of its power to drive a propeller.

False Propeller aircraft are more efficient than jet aircraft because: They process more air and don't accelerate it as much Turboprop aircraft are classified as power producers because: Both A and C: 12.1 Which statement is true with respect to Lift Coefficient (CL) and the Effect of Sweepback on Coefficient of Lift - Angle of Attack (AOA) curves? Design is a process of compromise and no one design is ever best at everything. 6.18 Thrust-producing aircraft have a fuel consumption roughly proportional to thrust output. 3.20 The component of the aerodynamic force that is perpendicular to the relative wind is ________________. 8.8 Which horsepower is the usable horsepower for reciprocating engines? 12.2 The main difference between CL-AOA curves for straight-wing aircraft is that. 5.24 For a given aircraft wing, if the wing span remains the same but the wing area increases, the aspect ratio will ____________. That portion of total drag associated with the production of lift. To get best range now the pilot must, Slow down by an amount less than the wind speed, 6.8 To obtain maximum range a jet airplane must be flown at, 6.9 Maximum rate of climb for a jet airplane occurs at, 6.10 Maximum climb angle for a jet aircraft occurs at. The relationship above, since it does not depend on the thrust, will plot on our constraint analysis chart as a vertical line in much the same way the stall case did, but it will be just to the left of the stall line. This limits your maximum allowable propeller diameter to 72 inches (36" x 2" = 72"). Design goals might include a maximum speed in cruise of 400 mph and a maximum range goal of 800 miles, however these do not occur at the same flight conditions. See also. Hg and a runway temperature of 20C. 7.14 (Reference Figure 7.2) Using Figure 7.2, find the velocity for maximum endurance for the airplane at 8,000 lbs. 9 0 obj endobj How does the Angle of attack vary from the root to the tip of a propeller for a fixed pitch prop? 12.19 Wind shear is confined only to what altitudes?

How does wind affect the airspeed that I should fly for maximum range in an airplane? Just as a car cannot get its best gas mileage when the car is moving at top speed, an airplane isnt going to get maximum range at its top cruise speed. What can be gained by accepting a lower cruise speed or a longer takeoff distance. 13.3 (Reference Figure 5.4) What speed is indicated at point A? 9.4 A lightly loaded propeller airplane will be able to glide ____________ when it is heavily loaded. 10.20 One of the dangers of overrotation is ________________. 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). 13.25 If an aircraft maintaining a constant bank angle increases its airspeed while maintaining a level, coordinated turn, what will the effect be on the radius of the turn? 5.4 When an aircraft enters ground effect, what effect does it have on induced drag? 6.19 For a turbojet, each pound of drag requires a pound of ____________ to offset it. 6.17 Maximum endurance will permit your aircraft to obtain the best distance for the fuel consumed. Nonetheless, we can see that three parameters; thrust, weight, and wing area, are important factors to consider in takeoff. Adapted from James F. Marchman (2004). 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? For a jet aircraft, this speed is very close to the speed at which the total minimum drag occurs. , Does an airfoil drag coefficient takes parasite drag into account? 10.16 As a rule of thumb, a 5% increase in takeoff distance can be expected for every _______ of uphill slope. (meters/second), Conversion of airspeed to horizontal velocity: The Role of Performance in Aircraft Design: Constraint Analysis, 9.6 Other Design Objectives Including Take-off, https://archive.org/details/hw-9_20210805, source@https://pressbooks.lib.vt.edu/aerodynamics, status page at https://status.libretexts.org. 5.20 The most aerodynamically efficient AOA is found at. 13.9 (Reference Figure 5.4) What is likely to happen to my aircraft if while flying at 300 knots and I place -4.6 G's on the aircraft? Raymer, Daniel P. (1992). 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? 7.16 With a typical drag curve, how many times does the thrust available line intersect the thrust required curve? These two ratios are both very reflective of the design philosophy and objectives of any particular airplane. Find the kinetic energy. 10.25 A common source for runway surface and slope information for a particular airport runway is the ______________.

A head wind is encountered. Maximum excess thrust occurs: For a jet-powered airplane, at approximately the maximum lift/drag ratio (L/D MAX). 3.23 The following are all examples of primary flight controls except _____________. 4.10 and the following data: W = 25,000 lb, wing area S = 300 ft2,CL(max), sea level, standard day. 12.20 When taking off in a microburst, a pilot should be aware of what change in performance when going from a tailwind to a headwind? Spreadsheets are indeed are helpful here, and may be programmed as follows: Same units of Velocity for climb and airspeed. We conclude this section with a dramatic photograph of an F-16 in a vertical, accelerated climb, Figure 13.8. In the equation above we have a very general performance equation that can deal with changes in both speed and altitude and we find that these changes are functions of the thrust-to-weight ratio, T/W, and the wing loading W/S. 2.2 For temperatures to be used in calculating the effects on performance, the appropriate absolute scale must be used. 8.20 As altitude increases, power available from a turboprop engine _____________. Aviation Stack Exchange is a question and answer site for aircraft pilots, mechanics, and enthusiasts. 9.11 As a power-producing aircraft burns off fuel, airspeed should be ____________ to maintain maximum range. 13.6 (Reference Figure 5.4) What will happen to an aircraft that is flown to the left of the curved lines on the left side of the flight envelope? What other design objectives can be added to the constraint analysis plot to further define our design space? Match the airfoil part name to the table number. To see if we can climb at the desired rate over a reasonable range of altitudes we would need to look at the climb relationship: This would give us another value of thrust needed to reach the target rate of climb for a given weight and, since the equation contains power required, which is drag times speed, the wing area would also be a factor. If there is an increase in air pressure, it will: Affect air density by increasing the density. The plot that will be different from all of these is that for takeoff. Now, to simplify things a little we are going to use a common substitution for the dynamic pressure: We will also define the lift coefficient in terms of lift and weight using the most general form where in a turn or other maneuver lift may be equal to the load factor n times the weight. The vehicle can get into the air with no lift at all. These relationships also involve thrust, weight, and wing area. So your graph of vertical speed versus airspeed will work just fine for finding the maximum climb angle.

It should be recalled that CLg is the value of lift coefficient during the ground roll, not at takeoff, and its value is /2k for the theoretically minimum ground run. 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. Typically it takes a form such as that shown in Figure 13.7.The shortest time-to-climb occurs at the flight velocity where is a maximum. 3. mean camber line Now we can expand the first term on the right hand side by realizing that. What is the equivalent power that it is producing? Maximum excess thrust occurs: For a jet-powered airplane, at approximately the maximum lift/drag ratio (L/D MAX).

Fw5| } First is that the figure from Raymer on the preceding page has two types of plots on it, one for ground run only and the other for ground run plus the distance required to clear a 50 ft obstacle. 7.19 Increasing the weight of a thrust-producing aircraft also increases the value of (L/D)max. Since you've already shown us a perfectly good graph of vertical speed versus airspeed, you might as well use it via the method described here. 12.24 For an aircraft to spin, both wings have to be stalled. 9.8 For power-producing aircraft, to maximize both efficiency and performance, you must (best answer). It usually is restricted to either the takeoff setting or the cruise setting. This data can give us a place to start by suggesting starting values of things like takeoff weight, wing area, aspect ratio, etc. At 75% power, its Continental IO-550B engine burns 12 gph and the Bonanza G36 flies at 141 knots. 2.15 The standard unit of measure for static pressure for pilots and altimeter settings is: 2.17 At _____________ altitude the static pressure is about half that at sea level. 4.15 A thicker airfoil results in what change to AOA? We would find, if we looked at the equations we derived for the other types of flight mentioned above that these same three parameters pop up everywhere. The groundspeed must be increased over the no-wind groundspeed by the amount of the tailwind. The standard RoC formula (using FPM and LBS) usually shows the excess HP at sea level at max gross to be around 33% of the rated HP for most GA propeller aircraft. 5.2 Wingtip vortices contribute to which type of drag? That's the actual angle of the slope of the straight line you drew on the graph. Maximum rate of climb for a propeller airplane occurs: at (PA-PR)MAX The lowest point on the PR curve is (L/D)MAX False Propeller aircraft are more efficient than jet aircraft because they process more air and don't accelerate it as much Turboprop aircraft are classified as power producers because: 5.23 For a given aircraft wing, if the wing span increases and the average chord remains the same, the aspect ratio will __________. 3.1 The mean camber line can be defined as: A line drawn halfway between the upper surface and the lower surface. I've read the other thread about the throttles, reversing, and feathering. 5.9 Drag due to the interference of boundary layers from different parts of the aircraft is known as, 5.10 The type of drag which is of particular importance to helicopter pilots is, 5.12 The most employed technique for reducing induced drag on modern aircraft is the use of, 5.14 Laminar flow airfoils have less drag than conventional airfoils, 5.15 Laminar flow airfoils have less drag than conventional airfoils because, 5.16 An airplane flying at CL MAX will have. 11.16 ____________ is caused by the buildup of the hydrodynamic pressure at the tire-pavement contact area. Climb Curves - Turbojet. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. 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). How to find trim condition of a sectional airfoil without knowing the angle of attack? 10.4 What effect does a headwind have on takeoff performance? What effect does an increase in AOA have on the laminar characteristics of a laminar flow airfoil? This would give a curve that looks similar to the plots for cruise and climb. 7.7 (Reference Figure 7.5) Figure 7.5 shows an increase in specific range with altitude because, Fuel flow remains about the same while airspeed increases, 7.8 A jet airplane is flying to obtain maximum specific range. 2.21 Calibrated airspeed is __________________ corrected for position and installation errors. With metric units for speed (meters per second), this is the case. 2.4 A piston-prop aircraft has a wing loading of 1600 N/m, and its drag polar is given by CD = 0.025 + 0.05CZ. <> In reality, the specific excess power relationship tells us how the excess engine power, Pavail Preq , can be used to increase the aircrafts potential energy (climb) or its kinetic energy (speed).
