Aircraft Design Practice Test 3

1. For jet aircraft, thrust loading is greater than the climb gradient.

2. As a designer our task is to generate fuselage through conic lofting method. If an intermediate C/S shape is elliptic then, what should be the appropriate value of conic shape parameter?

3. A prop driven A/C has BHP/W as 0.08. If density ratio is 0.2 and take off lift coefficient is 3 then find take-off parameter for the aircraft. Given wing loading W/s = 35.

4. The purpose of the longitudinal control lines is __________

5. As a designer, our task is to design wing layout such that the location of MAC from root chord or centre line is at 8ft. Find the appropriate value of the wingspan if wing is rectangular.

6. A good sketch should include _______________

7. A wing is to be loft with span as 2m and reference area of wing is 4m². If we want to design the wing with taper ratio of 0.6 then what will be the value of root chord?

8. Existing engine used for sizing is called as __________

9. What do you mean by longitudinal control lines?

10. A jet fighter has take-off gross weight of 10000 units. Find the appropriate length of the fuselage.
