To ensure safe operation of helicopters in the parking lot, launch and take-off and landing modes, the crew needs information about the magnitude and angles of direction of the velocity vector of the wind relative to the longitudinal axis of the helicopter. Obtaining such information on board the helicopter by traditional means is limited by the influence of inductive flow of the vortex column of the main rotor. The article reveals the principles, circuits and algorithms of the on-board system for measurement of the wind vector, providing the noise immunity of the measurement of wind in the parking lot, starting and take-off and landing modes of helicopter using spatially distributed aerodynamic and ion-label measuring channels.
