2. (Reference Figure 6.30) Using Figure 6.30, find the velocity for maximum endurance for the airplane at 12,000 lbs.
3. A total drag curve can also be considered a _____ curve for the given aircraft to maintain level flight.
4. An example of a power-producing aircraft is a
5. For a power producing aircraft, maximum range occurs at (L/D)max.
6. As an aircraft climbs in altitude, the drag of the aircraft is unaffected by altitude, but the true airspeed at which the drag occurs decreases as altitude increases.
7. Propeller aircraft perform worse than turbojets in the low-speed region.
8. Changing the weight of an aircraft changes the ______________ much more than the
9. A turboprop engine
10. Which of the following words should never be used in the discussion of jet aircraft?
11. Calculate the horsepower required (Pr) for a propeller-driven aircraft given the following information: Total Drag = 1058 lbs.Vk = 125 kts
12. Maximum rate of climb for a jet airplane occurs at
13. To obtain maximum range for a thrust producing aircraft, as fuel is burned
14. Endurance is _____________ proportional to fuel ow.
15. Which of the following altitudes is most efficient for a turboprop aircraft?
16. Regarding a propeller-driven aircraft, the Pr
curve is flatter in the low-speed region than the Tr curve, which explains why propeller aircraft perform better than turbojets in the low speed region.
17. Increasing the weight of a thrust producing aircraft also increases the value of (L/D)max.
18. Using Figure 6.17, what is the rate of climb (fpm) of the aircraft given the following conditions:
100% RPM TAS = 450 kts Aircraft Weight = 10 000 lbs.
19. The thrust available from a jet engine at 35 000 ft. altitude compared to that at sea level is:
20. In a turbojet, if Ta is constant, then Tr (drag) minimum is located at
21. Turboprop aircraft are classified as power producers because
22. Increasing the weight of a thrust producing aircraft moves all points on the thrust required curve
23. Calculate the horsepower required (Pr) for a propeller-driven aircraft given the following information: Total Drag = 1020 lbs. Vk = 172 kts
24. The power-required curves for an increase in altitude show that the
25. Which horsepower is the usable horsepower for reciprocating engines?
26. Using Figure 7.26, what is the rate of climb for your propeller-driven aircraft given the following set of conditions: Airspeed = VS(110 kts) Weight = 30 000 lbs. Pa = 3000 hp
27. A lightly loaded propeller airplane will be able to glide ____________ when it is heavily loaded.
28. The turboprop aircraft has its lowest specific fuel consumption at about 25,000 feet altitude because
29. According to Figure 6.10, a jet engine set at 90% maximum RPM will generate approximately what % maximum thrust?
30. An engine where the fuel-air mixture is forced into the cylinders by natural atmospheric pressure upon opening of the inlet valves.
