The Predator UAV has the following characteristics: wingspar = 14.85 m, wing area = 11.45 m², maximum weight = 1110 kgf, and fuel weight = 295 kgf. The power plant is a Rotax four- cylinder, four-stroke engine of 100 horsepower driving a two- blade, variable-pitch pusher propeller. Assume: the Oswald efficiency factor is 0.7; the zero-lift drag coefficient is 0.03; the propeller efficiency is 0.9; and the specific fuel consumption i 0.2 kgf of fuel per horsepower per hour. Calculate the maximum velocity of the Predator at sea level. The maximum velocity of the Predator UAV at sea level is m/s.
