TURBOACCELERATION DEVICE Russian patent published in 2012 - IPC F02K5/00 F03H99/00 

FIELD: engines and pumps.

SUBSTANCE: turboacceleration device is equivalent to impeller (engine with annular cowling), which also creates an air flow. Turboacceleration device is equipped with two or more stages of blades. Housing of device has converging and diverging pars. Blades of the device act as compressor in the converging part to create the required pressure of air flow before diffuser. Blades of the device act as pump in the diverging part after the diffuser to reduce the pressure after the diffuser. In converging part of the housing there can be made air inlet openings to increase the air flow mass. Engine of the device can be located both before the housing and at the end of it.

EFFECT: increasing air flow velocity.
