Helicopter thrust

WebThere are four forces acting on a helicopter in flight. They are lift, weight, thrust, and drag. See figure 2-1. Lift is the upward force created by the effect of airflow as it passes around an airfoil.Weight opposes lift and is caused by the downward pull of gravity.Thrust is the force that propels the helicopter through the air. Opposing lift and thrust is drag, the retarding … Web27 jan. 2024 · A helicopter tail needs to apply between 10 and 20% of the main rotor thrust in order to compensate for the torque of the main rotor. Re-designing the turbine engine to leave enough hot exhaust thrust for the tail is always less efficient than re-directing the extracted main shaft thrust, for instance with a fan driven by a gearbox.
