How is lift generated in a helicopter

Web21 jul. 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. WebA helicopter flies by means of the thrust that is created by the rotation of the blades of a main rotor that is mounted on a shaft above the fuselage, or body, of the aircraft. As the blades rotate, an airflow is created over them, resulting in lift. This raises the helicopter.

Airplanes are the most common application of lift and drag forces. In order to understand how airplanes take off and keep flying, we need to understand how lift, drag, and pitch can influence an airplane’s motion through air.

WebWhile some helicopters can reach around 25000ft, most commercial and military helicopters have a service ceiling ranging from 10000ft to 20000ft. As the air gets thinner at higher altitudes, a helicopter engine finds it difficult to breathe and the lift being generated by propellers is affected, since the air is much thinner.
