  • Patent number: 7954755
    Abstract: A method of launching a catapult, a catapult and a locking device for a catapult. The catapult comprises a carriage for fastening an aircraft. The carriage can be provided with a high acceleration by directing a launching force generated by a launching device thereto. The carriage can be held at a launching position by means of the locking device. The catapult further comprises a takeoff damper that generates a damping force having a direction opposite relative to the launching force. Accordingly, the takeoff damper restricts the acceleration of the carriage at the initial launching moments.

  • Patent number: 7562843
    Abstract: A method of launching a catapult, a catapult and a locking device for a catapult. The catapult comprises a carriage (4) for fastening an aircraft (5). The carriage (4) can be provided with a high acceleration by directing a launching force (F1) generated by a launching device thereto. The carriage (4) can be held at a launching position (6) by means of the locking device (9). The catapult further comprises a takeoff damper (34) that generates a damping force (F2) having a direction opposite relative to the launching force. Accordingly, the takeoff damper (34) restricts the acceleration of the carriage (4) at the initial launching moments.
