How Does A Helicopter Fly? - Referring To Forward Motion.


At first glance there is nothing visible that appears to be capable of generating forward thrust in a helicopter. What are the laws of aerodynamics that govern the forward motion of a helicopter? Is there a simple way of explaining how a helicopter moves forward?

    Well I guess the angle the rotor makes with the fuselage, what you call the "tilt" can be adjusted to generate that forward thrust by resolving the lift horizontally. Have I got it right? ... and thanks a lot for your response!

    I also thought so. The angle the top rotor makes with the fuselage gives it a forward thrust I guess. Thanks a lot for taking time off to respond! :)

    Yes, the "upthrust" is suitably called "lift" in aerodynamics and upthrust in hydrodynamics.
