WebJul 21, 2024 · The work done to keep the helicopter hovering is that generated by the motion of the rotor blades as they move through the air. The two key notions that go into the calculation of this work are lift and drag. Lift is the upwards-pointing force that balances gravity and keeps the helicopter hovering. WebApr 27, 2024 · $\begingroup$ @Crafterguy: No, even a flat plate would produce lift, but less efficiently than a proper airfoiled wing. Lift is perpendicular to the flow direction, and when the flow comes slightly from below, the lift force is tilted forward. The upward component is keeping the helicopter from falling any faster and the forward component keeps the rotor … pulpitis muelaWeb9. In general, the forward thruswt is achieved by tilting the entire helicopter forward. This converts some of the lift produced by the main rotor into a forward component of force. The same is true for turns. Yes, the swashplate may be used to create a thrust imbalance; but this imbalance does not provide any horizontal forces. pulpits synonym
