PURPOSE:To permit the remarkable reduction of a vibration upon launching by a method wherein a control power for reducing the vibration effectively utilizing the reaction force of a movable mass is applied on a launching tube by an actuator. CONSTITUTION:A movable mass 4 is attached movably to a launching tube 2 through a spring 5 and an actuator 6. An accerometer 7 detects the vibrating speed of the launching tube 2 through the integrator 9 of a controller 8 and generates a control force, proportional to the vibrating speed and having a reversed direction to the vibrating speed, in the actuator 6 through an electric power amplifier 10. The actuator 6 is constituted of a fixed core 11 and a movable core 12. A missile launching device 1 is added with a vibration controlling function in such a manner whereby the launching accuracy of a missile 3 may be improved and the affection of the vibration to a not yet launched missile may be reduced when the launching device 1 is provided with a plurality of launching tubes 2. |
