FIELD: aircraft engineering.
SUBSTANCE: proposed system (10) comprises bearing structure with sealed hollow shell (12) including first gas and enveloped by second gas, both being easier than air. Said hollow shell is prefilled with first gas via one-way air pressure control valve to prevent first gas leaks and altitude sensor (14). Altitude transducer (17, 21, 61, 66, 67, 68) connected with said hollow shell responds to altitude signal to vary the bearing structure buoyancy. Controller (15) is connected with altitude sensor and altitude transducer to respond to altitude signal and to one altitude count signal for maintenance of bearing structure at preset altitude.
EFFECT: improved characteristics.
