PROBLEM TO BE SOLVED: To solve problems in an emergency escape system for a helicopter, wherein we have no effective emergency escape system from the helicopter in spite of the development of the aircraft technology, and a person must get out from a door and wait for the opening of a parachute while naturally falling under a condition that the helicopter starts the filling soon because it does not glide being different from an airplane, when the emergency occurs in the helicopter. SOLUTION: In a case of an incident of emergency in the helicopter, an escape switch is turned on first of all to disconnect a rotor blade and a rotor head caught by the centripetal force. Then, a speed is changed to the outer tangential line of a rotor turning circle from the inertia force of the centrifugal force. Here, the rotor blade is blown away more quickly and powerfully when the explosion force of the explosive is added. Whereby, the environment for allowing a pilot to escape to the sky by a rocket motor mounted under a seat, can be quickly prepared. In this way, the emergency escape can be achieved by separating the rotor blade and the rotor head.
