FLYING VEHICLE Russian patent published in 2006 - IPC F02K3/77 

FIELD: aeronautical engineering.

SUBSTANCE: proposed flying vehicle has reservoir for fire extinguishant and turbo-jet engines whose turbo-compressor ducts include compressor, combustion chamber, turbine and nozzle located in succession. Compressor of at least one engine is multi-stage in construction with gas-and-liquid heat exchanger located between stages and connected with liquid reservoir by its liquid loop which is connected with turbo-compressor duct of at least one engine. Turbo-compressor duct of each engine is connected with turbo-compressor ducts of one or two other engines by means of gas-and-air heat exchangers. Gas inlet and outlet of each heat exchanger are connected respectively with turbine outlet and with nozzle of one of engines and air inlet and outlet are connected with compressor outlet and combustion chamber inlet of other engine.

EFFECT: improved flight characteristics due to use of onboard cooling capacity; enhanced economical efficiency of engines.
