FIELD: transport.
SUBSTANCE: invention relates to rotorcraft, namely, to VTOL aircraft. VTOL aircraft comprises airframe shaped to disc with several blades arranged thereat in circle and shaped to wing, compressed air source, air ducts connecting the latter with slitted diffusers of blades. Every blade is equipped with slitted diffuser oriented, in fact, across wing-like blade lengthwise axis. Blades and diffusers are oriented so that airflow incident from one blade flows over adjacent blade. Said blades are hollow, their cavities being connected with compressed air source while slitted diffusers are made in blade shells. One or several blades can be equipped with extra diffuser communicated intermittently with compressed air source. Said aircraft can be controlled by remote means.
EFFECT: enhanced operating performances of aircraft.
