The Bede BD-5J is a very small single-seat home-built jet airplane which became available in the early 1970 s. The data for the BD-5J are as follows: + Wing span: 17ft - Wing planform area: 37.8ft2 - Gross weight at takeoff: 960lb - Fuel capacity: 55 gal - Power plant: one French-built Microturbo TRS 18 turbojet engine with maximum thrust at sea level of 202lb and a specific fuel consumption of 1.3lb/(lb?h) We will approximate the drag polar for this airplane by CD?=0.02+0.062CL2? (a) Plot the thrust required and thrust available curves at sea level, and from these curves obtain the maximum velocity at sea level. (b) Plot the thrust required and thrust available curves at 10,000ft, and from these curver obtain the maximum velocity at 10,000ft. For the BD-5] (the airplane in Problem 5.1), calculate analytically (direcrly) (a) the maximum velocity at sea level and (b) the maximum velocity at 10,000ft. Compare these results with those from Problem 5.1.
