METHOD OF MISSILE MOVEMENT STABILIZATION AT UNDERWATER LAUNCH AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC F42B15/20 F42B10/14 

FIELD: rocketry.

SUBSTANCE: invention relates to rocketry, particularly to methods and devices of a missile stabilization at underwater launch from a moving carrier. Stabilization of a missile movement at underwater launch means ensuring the stabilization device mechanisms operation and serial commands of the control system. After the missile release from the transporter-launcher container and required by the cyclogram time delay the fixed stabilizers installed in the folded position above the missile obturator belt in such a way, that external incoming flow creates forces on the inner and the outer surfaces of the stabilizers caused by the effect of dynamic affluent at the flow streamlining the obturator belt on the inner surfaces and the disturbing flow effect on the outer surfaces, are unfixed and unfolded together with the unfolding mechanisms until the external unfolding moment appears on each stabilizer, damped is the angular speed of unfolding and fixed are the stabilizers in the final angular position by the structural means. After leaving the water the obturator belt is discarded, while the stabilizers operation is continued till separation of the aft section together with the burned out first stage.

EFFECT: proposed invention allows to improve parameters of stability of a missile movement at underwater launch from moving carriers at the underwater and the air trajectory sections till separation of the first stage and to optimize the missile weight and dimensions characteristics.
