Transcribed Image Text:Problem 3 - A small airplane that has a mass of 1,500 lb,m is about to take off. The airplane has
a coefficient of lift of 1.0 at an Angle of Attack (AOA) of zero and it linearly increases by 0.1 every
10 degrees; wings with a constant chord length of 3.5 ft and a total wingspan of 30 ft; a coefficient
of drag of 0.3; and a frontal area of 40 ft? that linearly increases by 5 ft every 10 degrees. If the
air is still, and the density of air is 0.076 lbm ft-3 at the ground level
what is the critical speed needed for takeoff?
If the runway is 1000 ft long, the total coefficient of friction between
the road and the airplane is 0.25, what is the average thrust needed to achieve the critical takeoff
speed?
