Question

A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activity
factor AF is 200 and its static torque coefficient is 0.05. The propeller’s integrated lift
coefficient is 0.3. 

If the aircraft’s lift to drag ratio is 10:1, calculate the requited thrust to weight ratio in order
to active a climb rate that is 8% of the flight speed.
