GAS-TURBINE ENGINE Russian patent published in 2012 - IPC F02K1/64 B64D29/08 

FIELD: engine-building.

SUBSTANCE: gas-turbine engine includes the driving assemblies, which are mounted under the gas-generator's fairing; a meshed reverse device and outer circuit channel's nozzle that is mounted lower from the flow. Outer and inner feedwells of the outer circuit channel's nozzle were constructed with axial plug at the vertical plane. Gas-generator's fairing contains segments near outer side. The dependence of axial length of air cavity that is situated on the nozzle outer feedwell (the feedwell is turned to the reverse device) to the axial length of reverse device mesh on the input is from 1,01 to 1,10. The reverse device is not hinged and it was performed with the ring elastic elements.

EFFECT: simplified access to the driving assemblies and provision of sealability of the reverse device at the forward thrust mode.
