Consider an electric-powered Cirrus SR22 aircraft cruising at a true altitude of 2000 m (air density p = 1.112 kg/m²). The aircraft's gross mass is m = 1500 kg, the true airspeed is 70 m/s, the lift-induced drag factor k 0.042, the zero-lift drag coefficient Cpo = 0.0254, and the reference wing area S = 13.46 m². Consider gravity g 9.81 m/s2 Figure 3. = a) Describe the typical application of a propeller-driven airplane [8] and show the reasons behind the application. [6] b) Find the propeller thrust T and propulsive power Pprop at the current flight condition. [6] c) If the whole chain propulsion efficiency is ntotal 0.85, and the battery pack mass limit is < 400 kg, find the minimum battery pack energy density for the aircraft to reach a 300 km cruise-only range at this flight condition.
