Vabanemisüsteem

Vabanemisüsteem, known in English as an escape system or ejection system, is a safety device designed to quickly remove occupants from a vehicle, most commonly an aircraft, in case of emergency. The primary purpose is to provide a means of survival when the vehicle is no longer controllable or presents an imminent danger.

The most well-known type of vabanemisüsteem is found in jet fighter aircraft. These systems typically involve a seat that is propelled upwards and away from the aircraft by a rocket motor. This rapid ejection carries the pilot clear of the stricken aircraft, allowing them to deploy a parachute for a safe descent. The sequence of events is highly automated, triggered by the pilot activating a lever or handle.

Modern vabanemisüsteem are sophisticated, incorporating features to ensure the safety of the occupant across a wide range of speeds and altitudes. This can include sequencing mechanisms that release canopy, deploy drogue chutes to stabilize the seat, and finally, deploy the main parachute. Some systems also include restraints and protection for the occupant's head and neck.

While most commonly associated with aircraft, similar principles can be found in other specialized vehicles where rapid occupant egress is crucial. The development and continuous improvement of these systems have significantly enhanced the survivability of aircrews and others in high-risk environments.
