Winning Camp: Aeronautical Engineering Quiz-1

Q1.Why did the early aeroplanes have small holes in the wing covering near the trailing edge? Q2.What are the effects of large camber on the upper surface of the (slow speed) wing? Q3.What are the advantages & disadvantages of the convex under surface on the (slow speed) wing? Q4.Explain the significance of high lift/drag ratio. Q5.      Is high lift/drag ratio of the wing always preferable? Q6.Describe a common method used in aeroplanes to get variable camber of the wing.
Q7.Draw a simple flap & a split flap. What is the advantage of split flap over the simple flap?
Q8.What is meant by aspect ratio? What are its values for sailplanes, gliders, transport aircraft,             fighter planes & hypersonic planes?
Q9.What are the advantages & disadvantages of high aspect ratio?
Q10.What are the wing-tip vortices and induced drag?
Q11.Why ‘induced drag’ is called so?
Q12.Explain what happens when an aircraft wing stalls?
Q13.What is the stalling angle for most of the slow …
