LIGHTER-THAN AIR SEMIRIGID COMBINED CONTROLLABLE FLYING VEHICLE Russian patent published in 1999 - IPC

FIELD: universal controllable semirigid aerostatic flying vehicles. SUBSTANCE: flying vehicle includes spherical flexible envelope and hollow rigid torus which is in contact with inner surface of envelope. Cruising engines are mounted on brackets of rigid torus. Mounted on outer surface of spherical flexible envelope is blowing system made in form of nozzles secured on outer surface of flexible envelope. Provision is also made for flexible funnel-shaped gastight diaphragm located in cavity of flexible envelope; it is used for separation of lighter-than-air gas compartment from thermostatic ballasting compartment which is located below. Cruising engines are provided with turbosuperchargers which are connected with nozzles by means of high-pressure hoses. Secured on rigid torus are ends of flexible coupling members of adjustable length which are connected with winches secured on nacelle. EFFECT: ease in service; high load ratio. 4 cl, 4 dwg
