FIELD: transport.
SUBSTANCE: invention relates to rotorcraft, namely, to VTOL aircraft. Aircraft comprises airframe, central engine composed of top and bottom vaned disks and rotary drives. Note here that said vanes are shaped to make vortex cells there between, mixing chamber and swirl chamber. Mixing chamber inlet is communicated via pipe and pump with vessel filled with fluid and outer air medium while mixing chamber outlet is communicated with vortex cells. Said vortex chamber is composed by surfaces of two truncated concentric cones of central engine and outer conical surface of the baffle arranged inside central engine housing. Vortex chamber inlet communicated with outer air medium while its outlet with slot between vaned top disk bottom surface and airframe outer surface. Aircraft incorporates at least two control engine arranged in opposition and in symmetry about its central axis and as near as possible to midlength section.
EFFECT: higher lift, power savings.
