The study was perform to examine dynamic response of a ship-based helicopter and its payload during emergency landing to the ship. The helicopter was impact at different forward velocities and different angles of impact with ship’s superstructure (hangar). The cause of the accident is an engine failure. During this study numerical simulations of a helicopter dynamic were executed for different initial conditions. Total acceleration versus time responses of airframe and payload were obtained. Peak acceleration of payload were calculated for each forward velocities and angles of impact.
