HQ prop are designed to give you maximum control and responsiveness up at speed. Anoptimized design method was developed to design these propellers. For a given operative condition (thrust, rotation speed, blade number, propeller diameter, hub radius) and profile distribution along the blade, the present methodcan determine the chord and angle distribution of the blade, together with its torque and thrust of the maximum efficiency propeller. the energy loss of maximum efficiency propeller is minimum. If all the profile along the blade operates at the maximum efficiency (maximum lift to drag ratio), the propeller efficiency is maximum. The optimized design methodgives us an optimized blade geometry that is then modeled.
