A smoke mitigation system for an aircraft includes an exhaust shutter in an upper region of a fuselage of the aircraft. The exhaust shutter has a closed position in which the exhaust shutter does not exchange air from outside of the fuselage with air inside of a passenger cabin that is within the fuselage and an open position in which the exhaust shutter exchanges air from outside of the fuselage and inside of the passenger cabin, thereby enabling escape of smoke from the passenger cabin. The system includes one or more devices for opening the exhaust shutter and a device for initiating opening of the exhaust shutter. The device for initiating opening of the exhaust shutter includes mechanisms for determining that it is safe to open the exhaust shutter.

A novel crash-resistant aircraft includes a fuselage and an aircraft base connected together via a movable fastener, and said fuselage comprises a cockpit, a cabin and an empennage. The aircraft base comprises a belly hold cargo bay, a fuel tank, an undercarriage, a power unit and wings. The empennage is also connected to the tail end of said fuselage via a movable fastener. A crash-resistant propeller system capable of bringing said fuselage upward is set up at the top of said cabin, a crash-resistant recoil devices set up beneath said cabin. The crash-resistant aircraft also comprises a control system disposed in said cockpit, and when said aircraft is in an accident in midair, said control system releases said movable fastener to abandon said aircraft base and said empennage. Also disclosed is a crash-resistant operation method of the crash-resistant aircraft.

An aircraft that includes an outer skin having an opening formed therein, and a cargo compartment including a plurality of side walls that define an interior of the cargo compartment. The plurality of side walls are positioned such that the interior is in flow communication with the opening. The aircraft further includes a hinged panel coupled to the outer skin. The hinged panel is operable between a closed position for covering the opening and an open position for exposing the interior to an ambient environment outside the aircraft. A release device is configured to retain the hinged panel in the closed position, and configured to release the hinged panel for movement into the open position when an unexpected combustion event forms in the interior.

A method and an apparatus for controlling an aircraft are disclosed. The method includes: determining a horizontal velocity V.sub.h and a vertical velocity V.sub.v of the aircraft; acquiring, along a moving direction of the aircraft, an object having a distance that is no greater than a preset distance L away from the aircraft; predicting, according to the horizontal velocity V.sub.h, the vertical velocity V.sub.v, and the preset distance L, a position relationship between the aircraft and the object after the aircraft flies the preset distance L; and controlling the aircraft, by using a preset control measure, if the position relationship meets a preset relationship.
