RAM-JET ADJUSTABLE SPLIT NOZZLE Russian patent published in 2019 - IPC F02K1/12 F02K7/18 

FIELD: machine building.

SUBSTANCE: invention relates to the engine machine building, in particular to the ram-jets adjustable split nozzles. Adjustable split nozzle contains pivotally mounted on the housing in two annular rows subsonic driving and driven flaps and supersonic driving and driven flaps forming the flow path, the flaps synchronization system and the nozzle throat area control system, including actuators connected to the fixed on the driving subsonic flaps levers. Nozzle throat section control system additionally contains installed at an angle to the nozzle central longitudinal axis pyro pushers, which rods rest against the driving subsonic flaps. Each lever is made of two pivotally connected parts and contains these parts in the working position rigid linear fixation device.

EFFECT: invention allows to reduce the volume required for the nozzle throat section control system placement in the starting position.
