The Bede BD-5J is a very small single-seat home-built jet airplane which became available in the early 1970s. The data for the BD-5J are as follows: • Wing span: 17 ft • Wing planform area: 37.8 ft2 • Gross weight at takeoff: 960 Ib Fuel capacity: 55 gal • Power plant: one French-built Microturbo TRS 18 turbojet engine with maximum thrust at sea level of 202 Ib and a specific fuel consumption of 1.3 lb/(Ib-h) We will approximate the drag polar for this airplane by Cp = 0.02 + 0.062C² (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 10,000 ft, and from these curves obtain the maximum velocity at 10,000 ft.
