FIELD: manufacture of turbines; flying vehicles, shipbuilding and land transport facilities provided with propellers creating the controllable application force. SUBSTANCE: first part of main flow of working medium "S" is fed tangentially to revolving rotary nozzle 1 in direction opposite to sense of rotation; other part of working medium - active jets "B" which has been preliminarily swirled at blades 3 is fed through micronozzles 5 of rotary nozzle 1. Braking of main flow at active jets in area of revolving boundary layer creates zone of local increased pressure and as a result, force of controllable application. Rotary nozzle may be set in rotation by radial-flow turbine 4. EFFECT: enhanced efficiency of creation of controllable application force. 3 cl, 3 dwg |
