FIELD: aeronautical engineering. SUBSTANCE: device has gas flow source in form of centrifugal blower and lifting plane made in form of many aerodynamic surfaces having wing profile in section. Device has circular tubular housing with swivel nozzles of varying section in its lower portion for discharge of gases. Arranged in housing are centrifugal blower and lifting planes which are mounted in turn asymmetrically relative to axis of circular housing; part of them are swivel in their construction. Circular housing is embraced by casing provided with air intake openings. Interior of casing is brought in communication with centrifugal blower. Device is provided with at least two circular housings with gas streams flowing in opposite directions. Innovation of invention consists in higher difference of pressures above and under wing due to higher pressure of gas flow created by centrifugal blower in closed space of circular tubular housing due to adjustment of gas flow escaping from circular housing through swivel nozzles. Besides that, lifting force is increased due to reactive thrust generated at escape of gases from nozzles. EFFECT: increased lifting force and consequently increased altitude of flying vehicle. 2 dwg |
