The development of aviation was invariably accompanied by the creation of effective means of rescuing pilots - catapults. However, for a long time this was the privilege of exclusively military pilots, while the pilots of low-speed aircraft - sports, training, agricultural and others were forced to leave the machines in distress the old fashioned way - "by hand".
Nowadays, this problem has been solved, thanks to the team of engineers of NPP Zvezda named after Academician G. Severin, who created a unique super-light ejection system SKS-94 for light civil aircraft. The catapult can be used at speeds up to 400 km / h and altitudes up to 4000 meters.
The SKS-94 is a controlled ejection system that includes a 28 kg seat connected to a telescopic firing mechanism. To eject, the pilot needs to pull out a special handle, after which the headrest is shot. The headrest is a kind of battering ram, breaking the cockpit canopy and activating the pilot chute.
After that, the firing mechanism comes into play, which, with the help of the harness, pushes the pilot out of the cockpit. For this, of course, not the most powerful rocket in the world is used, but a squib, sufficient to give the pilot's seat the required speed. SKS-94 is reliable and unpretentious. It is designed for 20 years of operation with a periodicity of regulations and inspections of two years.
