AIRCRAFT POWER PLANT CONTAINING HEAT EXCHANGERS OF AIR-LIQUID TYPE Russian patent published in 2022 - IPC F02C7/14 F01D25/14 

FIELD: aviation.

SUBSTANCE: aircraft power plant (10) contains a gas turbine engine surrounded by nacelle (26) containing annular air intake (30) extended around the gas turbine engine by two annular walls, inner (34) and outer (36), respectively, that are designed to be blown with air flow (28, 40) at least during the aircraft flight, different in that the mentioned inner and outer walls, each, contain or have at least one network (42) of channels made on it, forming heat exchangers, the channel network of the inner wall has at least one liquid output sequentially connected to at least one liquid input of the channel network of the outer wall, and the power plant contains liquid circulation means (46, 50, 52, 54) connected to at least one liquid input of the channel network of the inner wall in order to supply liquid to it, and connected to at least one liquid output of the channel network of the outer wall in order to collect liquid.

EFFECT: this invention is aimed at proposing the liquid circulation architecture at the level of walls of the so called “cooling” nacelle with the optimization of a pair of dissipated power –produced pressure loss, as well as flight mass.
