METHOD OF SIMULATION OF CONDITIONS OF ROCKET LAUNCHING FROM SUBMARINE AND SYSTEM FOR ITS REALIZATION Russian patent published in 1997 - IPC

FIELD: determination of parameters of rocket launching from submarine in ground conditions. SUBSTANCE: hydrostatic pressure at launching depth, longitudinal resistance force, rocket weight and friction force at rocket motion in launching tube are simulated by solid-propellant rocket engine thrust on rocket mock-up placed in launching tube on ground supports. Engine thrust is directed against mock-up motion, and its magnitude is determined according to mathematical dependence. After engine delivers constant thrust mock-up ejection gas generator is actuated. System uses launching tube on ground supports, ejection gas generator, rocket mock-up with obturating belt and solid-propellant rocket engine. The latter is secured on mock-up with the aid of intermediate section connected to launching tube through blasting elements, and engine nozzle exit section is oriented in direction of mock-up ejection from launching tube. EFFECT: facilitated procedure. 2 cl, 3 dwg
