translational lift
1Translational lift — is the extra lift created/received when a helicopter s forward speed increases from the hover. It should be noted that if there is a steady wind (above 10 knots) a helicopter in the hover may already be in translational lift.It is created when… …
2translational lift — The additional lift (or rotor thrust) obtained through air speed because of the increased efficiency of the rotor system, whether it is when transitioning from a hover into forward flight or when hovering in a wind. During a hover, the rotors are …
3translational speed — That speed where translational lift is acquired and transverse flow occurs …
4Vortex ring — A vortex ring, also called a toroidal vortex, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a doughnut shape. The movement of the fluid is about the poloidal or circular axis of the… …

7Flap back — or blowback is a phenomenon affecting the rotor of a helicopter as it overcomes dissymmetry of lift through flapping. In forward flight, rotor blades experience more lift as they rotate forward. This increased lift is a result of an increased… …
