Prior to takeoff, the pilot of a 3000-kg twin-engine airplane tests the reversible-pitch propellers by increasing the reverse thrust with the brakes at point B locked. Knowing that point G is the center of gravity of the airplane, determine the velocity of the air in the two 2.2-m-diameter slipstreams when the nose wheel A begins to lift off the ground. Assume P = 1.21 kg/m3 and neglect the approach velocity of the air.
A launch vehicle has 6 engines operating in parallel which are fed from the same propellant tank.
Initially, each engine has an equivalent exhaust velocity of 3500 m/s and consumes 400 kilograms of
propellant per second.
One of the engines malfunctions and consequently operates at 50% thrust and 120% propellant
consumption. Calculate the equivalent exhaust velocity in m/s of all engines if treated as a single
engine, including the malfunctioning engine in your calculation.
(14.73) The jet engine shown scoops in air at A at a rate of 90 kg/s and
discharges it at B with a velocity of 600 m/s relative to the airplane. Deter-
mine the magnitude and line of action of the propulsive thrust developed by
the engine when the speed of the airplane is (a) 480 km/h, (b) 960 km/h.
