Emergency parachute to lower complete aircraft - has parachute attached to front of fuselage and rear of fuselage is formed as crumple zone to absorb impact energy

摘要

One or several parachutes (1), are attached to the fuselage forward of the centre of gravity (S) so that the fuselage approaches the ground at an angle ( alpha ). The rear of the fuselage may be formed as a crumple zone to absorb energy. Weak points in the wings may be provided to allow them to break off on impact. Rocket or air pressure devices may be used to ensure rapid deployment of the parachute. ADVANTAGE - On impact of aircraft with the ground passengers are pressed into their seats, and energy of impact is absorbed in the crumple zones or wing fractures.
