AIRCRAFT Russian patent published in 2014 - IPC B64G1/40 B64G1/26 

FIELD: aircraft engineering.

SUBSTANCE: aircraft comprises airframe, jet engines, fuel feed, ignition and flow control unit, unit of symmetric tapered combustion chambers, two units of exhaust nozzles and units of symmetric bent exhaust pipes with ends. Every combustion chamber is rigidly coupled with appropriate exhaust nozzle of the first unit of exhaust nozzles behind the combustion chambers and rigidly connected with appropriate exhaust nozzle of the second unit of exhaust nozzles ahead of combustion chamber. Every nozzle is rigidly connected with appropriate bent exhaust pipe inside the airframe located ahead. Hydraulic inputs of the unit of symmetric bent exhaust pipes are communicated with appropriate hydraulic outputs of control unit.

EFFECT: decreased time of approach to remote objects, decreased power consumption.
