Vortex ring state (formerly referenced as settling-with- power) describes an aerodynamic condition in which a helicopter may be in a vertical descent with between 20 and 100 percent power …

Vortex Ring, (sometimes called ‘settling with power’ or ‘power settling’) is a flight condition in which a helicopter that is receiving power from its engine (s) loses main rotor lift and …

One of the most dangerous situations a helicopter pilot can get into is called Vortex Ring State. Learn what it is, how to prevent and how to get out of it.

Vortex ring state describes an aerodynamic condition where a helicopter may be in a vertical descent with up to maximum power applied, and little or no cyclic authority. The term “settling …

Feb 1, 2018 · Sometimes called settling with power, vortex ring state happens when a helicopter descends at a rate that puts the blades in their own downwash; instead of drawing clean air …

For a helicopter to enter vortex ring state, it must be at low airspeed with a significant descent rate. It must also hold this condition for a few seconds, while the vortices pile-up around the …

The Vortex Ring State is a very dangerous phenomenon that occurs at low airspeeds. It can lead to loss of lift and control of the aircraft, with potentially serious consequences when close to …

Nov 4, 2024 · The vortex ring state (VRS) is a critical issue for helicopters and eVTOLs, risking loss of control during descent. Evaluating recovery techniques through simulations, flight tests, …

It shows that conventional helicopters are likely to enter in vortex-ring-state regime at lower descent rates compared to tiltrotors. On the other hand, tiltrotors can encounter VRS at higher …

This session will explain how to recover from vortex ring state using a highly efficient set of techniques, especially in terms of altitude loss: the Vuichard Recovery Techniques.
