Abstract: A safety rescue aircraft is provided, which scheme can be adapt to a fixed-wing aircraft and a rotorcraft. In the case of large or medium sized aircraft, at least two channel shaped floors are provided. When the aircraft is in danger, present aircraft can ignite explosive bolts (13) for wings (4), the empennage (6) and the front undercarriage to cut off the operating linkages and electrical pipelines lead to them, thereby the empennage, the front undercarriage and the wings containing engines, tanks and the back undercarriage can be cast away. At the same time, the parachutes (20) provided in the top of fuselage and empennage are opened, andthe airbags in the bottom of the fuselage are inflated. Thus the fuselage can land slowly and stably in the aid of parachutes and airbags, and the safety of passengers and fuselage can be guaranteed effectively.
