LAUNCHING DEVICE Russian patent published in 1995 - IPC

FIELD: launching devices. SUBSTANCE: used as drive of launching device is hydraulic pump connected with frame and launching carriage by means of pipe line and flexible hydraulic chamber embraced by strands of tractive elements made of elastic and flexible threads, for example caprone thread. When working fluid is fed from hydraulic pump to flexible hydraulic chamber, its volume is increased and length is decreased. As a result, launching carriage is drawn off causing tension of strands of tractive elements on working section. In loaded state launching carriage is locked by means of retainer. Before launch, valve is opened in pipe line and working fluid escapes from flexible hydraulic chamber. At moment of launch, retainer releases launching carriage and energy of elastic deformation of strands of tractive elements on working section is consumed for acceleration of launching carriage and object carried on it. EFFECT: simplified construction, reduced mass and reduction of revealing factors. 4 dwg
