Horizon Europe Project: Helicopter Vortex Ring State Experimental Research (2 Launch) (European Union Aviation Safety Agency (EASA))
The vortex ring state (VRS) is an aerodynamic condition for helicopters normally generated in nearly vertical or vertical descent when the relative upward air velocity equals the downward induced main rotor flow rate. This research should provide a better understanding of the VRS phenomenon on different kinds of helicopters, the analytical and simulation prediction methods, and flight test methods for its determination. It should further provide an indication of the effectiveness of alternative recovery … Ansicht der Beschaffung »
