FIELD: engines and pumps.
SUBSTANCE: vortex ejector propeller is made in the form of streamlined hollow nacelle the internal surface of which forms an air path consisting of in-series located inlet device made in the form of confuser, diffuser, vortex chamber and outlet device. Nacelle is provided with device for compressed air supply inside air path in the form of nozzles interconnected with compressed air source, located in front part of nacelle and directed at an angle equal to 10-60° to axis of air path so that vortex is created.
EFFECT: reduction of weight and improvement of reliability.
