WebMay 30, 2004 · Flapping to equality is how the lift is kept equal around the disk if the pilot does not move the cyclic. Flapback serves as feedback to inform the pilot that the stick … The above describes the basics of how helicopters fly. However, there are other aerodynamic effects that take place in helicopter flight. Let’s now take a look at each of the more important ones in turn… 1. Flapping to Equality 2. Flapback 3. Translational Lift 4. Ground Effect 5. Ground Resonance 6. Tail … See more The rotor blades of a helicopter are identical to the wings of an airplane. This means that each blade is an aerofoil that, when placed in an airflow, deflects the air in order to produce … See more The magnitude of TRT is changed by increasing or decreasing the pitch angle of the rotor blades, and thereby their angle of attack. The pilot does this by using the collective or lever on … See more So the theory of how helicopters fly is quite complicated, but certainly not impossible to understand. However, the above really only explains the basics. There are other … See more So we now have a way to lift the helicopter into the air and hover it. But we also need to be able to move it forwards…and sideways and … See more

WebApr 6, 2024 · However, this flapping to equality only works up to a certain speed, for several reasons. So now, let’s take a look at what happens at high speed, and why helicopters cannot fly that fast. Why Helicopters Cannot Fly Fast The Phenomenon Of Flapback. As explained above, the helicopter flies along, with the blades flapping and … WebJul 28, 2024 · What is flapping to equality? During the movement of a helicopter rotating blade, the speed of airflow over the advancing blade is higher than the retreating blade, resulting in production of an unequal amount of lift.
