FIELD: aviation.
SUBSTANCE: device consists of a single-disk open centrifugal wheel with a two-way inlet of the air medium and with straight radial blades (1), a fixed convex-concave annular body (2). The body is a surface of rotation bounded by the upper and lower circumferences, with an acute angle of the fluid outlet with respect to the horizontal of the body outer edge inner surface. The blades of the straightening device (3), the brackets (4) for fixing the centrifugal wheel drive to the bearing assembly (5) housing are installed on the body inner surface.
EFFECT: due to the reduction of local hydraulic losses of the energy of the flow, an increase in the specific thrust and a decrease in the weight and dimensions of the device are achieved.
