FIELD: engines and pumps. ^ SUBSTANCE: channel includes the first cylindrical element of the channel, to which working gases are supplied and which is interconnected at the outlet with two second elements of the channel, the directions of which differ in the first plane. Each of the second elements of the channel is interconnected on outlet side with the third element of the channel. Every third element of the channel opens to axial semi-nozzle and forms the bend formed with the first part supplying the gas flow in the direction from the axis, and the second part located after the first part and supplying the gas flow towards the axis so that hot zones inside the channel at the inlet of outlet manifold are not seen from behind. The other invention of the group refers to operating method of outlet manifold, which consists in air bleeding from compressor of gas generating plant for air supply to control means of flow distribution of each of the semi-nozzles. One more invention of the group refers to gas turbine engine containing the above outlet manifold. ^ EFFECT: inventions allow reducing infrared radiation of gas turbine engine of aircraft. ^ 17 cl, 9 dwg |
