An impulse dampening system reduces peak pressure and impulse acoustic pressures of an acoustic wave to a level that permits initiation of an emergency egress system by personnel in a submerged/flooded cockpit following landing or crashing into water. Initiation of the emergency egress system is available in the air or after the aircraft is in the water. The system attenuates the impulse of the acoustic wave at least 35 dB, where the acoustic wave is usually produced when a detonation chord is initiated. The system includes a first layer of dampening media, a second layer of dampening media, a viscous lensing medium between the layers, and a hard shell.

The present disclosure relates to an aircraft comprising a passenger module, and also a method of protecting a passenger on an aircraft. The passenger module is configured to be ejected through a skin of the aircraft in response to an ejection command. The ejection command may be given in response to a fatal condition to the aircraft being detected or manually indicated.

A pyrotechnic egress system may comprise a case defining an opening, a gas generator disposed within the case, the gas generator configured to generate a gas flame in response to being ignited, and an ignition line disposed at the opening and configured to ignite the gas generator, wherein the case directs the gas flame through the opening for deflagrating a window.

A bi-directional egress hatch for a passenger aircraft may allow passengers to rapidly and safely exit an overhead cabin of the aircraft onto the main deck, while allowing cabin crew to safely ascend into the overhead cabin if need be. Hatch panels may blend in with overhead bin doors and ceiling panels of the main cabin; the inner portions of the hatch panels (facing the overhead cabin) may include anti-skid portions and graspable handles for descending passengers. The hatch may be easily activated by a passenger with a single motion (or remotely activated, or autodeployed). Once activated, the hatch panels may swing open and a telescoping ladder may deploy from the inner portion to the main deck, remaining rigid once reaching the floor. Similarly, any barriers protecting the ladder from passengers in the overhead cabin may be released, granting access to the telescoping ladder.

Embodiments of the present invention disclose a method, a computer program product, and a system for detecting a flight emergency and executing solutions for the emergency. Embodiments of the present invention describe a method comprising: receiving a sensor alert, executing an alert solution associated with the sensor alert, determining flight condition, determining flight condition is a crash condition, and deploying a set of parachutes.

The invention relates to a body (2); a canopy (3) disposed on the body (2) so as to be able to move relatively to the body (2), enabling access and providing protection to the cockpit; more than one hook (4) located on the canopy (3); more than one pin (5) located on the body (2), enabling the canopy (3) to be fixed to the body (2) by engaging to the hook (4); an open position (A) enabling access to the cockpit so as to leave a gap between the canopy (3) and the body (2); a closed position (K) in which the canopy contacts the body (2) so that there is almost no gap left between the body (2) and the canopy (3); and a locked position (L) in which the canopy (3) is fixed to the body (2) by locking the pin (5) to the hook (4).
