Abstract
An aircraft having an annular body, defining a central passageway; an upper deflector, a lower collector and a fluid drive in the passageway. Air is accelerated by the fluid drive and circulates around the annular body. The collector divides the circulating air and directs a portion into passageway and a portion to beneath the aircraft to provide a further thrust.
Claims14
An annular recirculating fluid apparatus comprising:
- an annular body having a passageway, the body having an upper stationary, non-adjustable airfoil surface and being further configured to facilitate circulation of fluid around said body and through the passageway,
- a fluid drive to accelerate fluid through said passageway,
- a deflector disposed above said passageway and at least partially overlying said upper airfoil surface to direct accelerated fluid from said passageway outwardly across said upper airfoil surface of said annular body, and
- a collector disposed below said passageway, said collector having a peripheral edge terminating short of the outermost periphery of said annular body, for directing a portion of fluid circulating around and under said annular body to said fluid drive, and directing another portion of fluid circulating around and under said annular body downwardly away from said annular body.
