Embodiment Construction
[0018] The present invention will be further described now in conjunction with accompanying drawing:
[0019] combine figure 1 , figure 2 , The invention provides a novel cooling hole structure on the wall surface of the combustion chamber flame cylinder with a convex wall oblique hole. figure 1 is the overall picture of the wall of the combustion chamber flame tube, figure 2 is a side view of the wall of the combustion chamber flame tube, image 3 It is a cross-sectional view of the wall of the flame tube in the combustion chamber. It can be seen that the convex wall inclined hole channel and the flame tube form an acute angle protruding from the flame tube wall, and the inclination angle β of the baffle plate on the inner wall of the flame tube is the same as the angle α of the convex wall inclined hole channel. Figure 4 It is a top view of the wall of the combustion chamber flame tube.
[0020] In the traditional film cooling hole structure of the combustion chamber,...
