Problem 06.002 - Calculate total drag An airplane weighing 5,000 lb is flying at standard sea level with a velocity of 525 mi/h. At this velocity, the L/D ratio is a maximum. The wing area and aspect ratio are 200 ft² and 8.5, respectively. The Oswald efficiency factor is 0.93. Calculate the total drag on the airplane. Assume poo = 0.002377 slug/ft³. The total drag on the airplane is lb.
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA The image below is a cross-section of a Darrieus-type and wind turbine. Find the cross Sectional moment provided by the bottom airfoil under the following circumstances. Calculate the lift coefficient based on the formula CL = 27 (α -αL=c) Assume that stall is not occuring The airfoil has a zero lift angle of attack of O degrees and a sectional drag coefficient of 7x10- -3 10 = 41-7 RPM 6 = 13 degrees R = 188 m V = limls C =017 m Airdensity = 0.91 kg/m3 Find moment in N.m C R co C
Problem 06.025 - Calculate maximum velocity The Predator UAV has the following characteristics: wingspan = 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 is 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.
