What is the maximum power input to a propeller to ensure that its maximum feasible propulsive efficiency is at least 80% assuming it has a diameter of 1.4 m and it spins at 50 rev/s at a flight speed of about 75 m/s when air density is 0.5 kg/m^3? 1 - eta_prop_max/eta^3_prop_max = 2C_p/piJ^3 = 0.391 4b) What is the answer to 4a when the angular speed is doubled? 4c) What is the answer to 4a when the diameter increases to 1.8 m? 4d) What is the tip Mach number in example 4c assuming the sound speed is 300 m/s (at 50 rev/s)

Solution

Compare the two designs descirbed in table below when each is transmitting 1200lb.in of torque at its output shaft, which rotates at 20rpm. Compute the forces on the worm gear, the efficieny and the input power required
