Method bungee launch, catapult and fixing device.

摘要

A method of launching a catapult, the method comprising: generating a launching force (F1) by means of a launching device; keeping a carriage (4) immovable by means of a fixing device (9) at a launching position (6) of the catapu directing the launching force (F1) to the carriage (4) which is movable from the launching position (6) towards a release position (7) guided by a body (1) of the catapu releasing the locking device (9) at a time of the launch, whereby the carriage (4) moves towards the release position (7) at a speed accelerated by the action of the launching force (F1); , launch and aircraft (5) arranged in the carriage (4) in the release position (7), characterized by directing a maximum damping force (F2) of at least one takeoff damper (34) to influence the carriage (4) at the time of release, being the direction of the force of opposite damping relative to the launching force (F1), and resisting the damping force (F2) movement of the carriage (4) to the position release (7); reducing the magnitude of the damping force (F2) relative to the carriage movement; and reducing the damping force (F2) from maximum to minimum once the carriage (4) has moved a damping distance (L) to the predetermined release position (7).
