A Scheme of Crosswind Resisting for Unmanned Helicopters in Forward Flight Phase
The flight ability in the forward flight phase is the basis of the over-the-horizon flight of unmanned helicopter, and crosswind is the most important factor affecting the helicopter safety in forward flight phase.Therefore, the strategy of resisting lateral wind in the forward flight phase restricts the ability of the over-the-horizon flight of unmanned helicopter.At present, the main strategies of UAVs are the side-slipping method and the crabbed method.Side-slipping method resists the lateral force on the plane by crosswind through plane rolling.Using this method the unmanned helicopter flies with the sideslip.Crabbed method eliminates the sideslip through turning the heading to airspeed direction.The unmanned helicopter flies without the sideslip with this method.Four schemes are designed for crosswind resisting according to the two strategies, and comparison and analysis are carried out for meeting different engineering requirements respectively.
