Embodiment Construction
[0023] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] A new type of multi-slope hole plate ellipsoidal pendulum cooling structure for aerospace engines in this embodiment includes cooling slant holes 2 uniformly arranged on the wall 1 of the combustion chamber flame tube, and the cooling gas can enter the combustion chamber flame through the cooling slant holes 2 In the cylinder and on the inner wall of the combustion chamber flame cylinder, a gas film is formed, and the high-temperature gas and cooling gas flow from front to rear in the combustion chamber flame cylinder, wherein: the cooling inclined hole 2 is connected with the bleed air channel 3, and the bleed air channel 3 extends to The inside of the combustion chamber flame tube is connected with a spherical axis 4. The ellipsoid 5 is located between the front and rear adjacent cooling oblique holes 2 inside the combustion chamber fla...
