ABSTRACT:
A brake and release means for a rotary nozzle body. The rotating shaft of the nozzle body is mounted in a missile casing and delivers a gas thrust jet substantially perpendicularly to the direction of the longitudinal axis of the missile for guiding the missile. To be able to adjust the angular position between the rotary nozzle body and missile with high control frequency and exactly, a brake and release device is provided which comprise a friction coupling and an electromagnetic setting means. The frictional engagement and the release of the rotary nozzle body occur through a force control in that through the setting means, a control force axially directed counter to the tensioning force which assures the frictional engagement is exerted on the rotary nozzle body. To support the release of the rotary nozzle body, it may be provided further to build up a gas pressure between the friction faces of the friction coupling.
