HEAT INSULATING CASING OF SHIP GAS TURBINE ENGINE Russian patent published in 2017 - IPC B63H23/00 F02C7/18 

FIELD: engine devices and pumps.

SUBSTANCE: heat insulating casing of the ship gas turbine engine comprises a ship gas turbine engine with exhaust confuser branch pipe turned relative to the engine axis with exhaust cut at level of exhaust pipe base, an inlet ventilation branch pipe, an outlet branch pipe of the casing connected thereto. An annular perforated partition is arranged in the outlet branch pipe of the casing at a distance from a flange connector and the exhaust pipe, in which holes are made with the possibility of providing required consumption of ventilation air for engine cooling. The partition is secured over outer diameter the on casing outlet branch pipe, and along inner diameter is made in form of elastic blades bent towards exhaust side or secured over inner diameter on the exhaust confuser branch pipe, and outer diameter is made in form of elastic blades bent in opposite direction from the exhaust and resting with possibility of motion on inner surface of the casing outlet branch pipe.

EFFECT: improving the reliability of operation of marine gas turbine engines.
