１の冷却効果を高めている。 Generally, as an effective cooling means for a combustor of a gas turbine engine, the means shown in FIGS. 1 and 2, for example, are known. In this, 1 is a double-structured inner cylinder of the combustor, and the inner cylinder 1 is formed by interposing a large number of cooling pins 4 between an inner peripheral wall 2 and an outer peripheral wall 3, The combustion gas is flame-stabilized inside the inner cylinder 1. Some of the cooling air flowing along the outer surface of the outer peripheral wall 3 as shown by the arrows flows through a large number of air inflow holes 3a provided in the outer peripheral wall 3 and a large number of air inflow holes 3a provided in the inner peripheral wall 2, as shown by the arrows. The air flows inside the inner circumferential wall 2, that is, into the inner cylinder 1 through the inflow hole 2a, flows along the inner surface of the inner circumferential wall 2, and not only cools the film, but also flows from the air inflow hole 3a of the outer circumferential wall 3. When the air flows into the cooling air passage 5 formed in the space between the two peripheral walls 2 and 3, impingement cooling is performed as shown by the arrow by the collision with the outer surface of the inner peripheral wall 2, and the cooling pin 4 is cooled. Heat transfer cooling is performed on the surface, thereby increasing the cooling effect of the inner cylinder 1.

た。 However, the inner cylinder 1 formed in this manner is manufactured by molding the inner and outer peripheral walls 2 and 3 into a predetermined shape with a cooling pin 4 interposed between the inner and outer peripheral walls 2 and 3. Therefore, due to deformation caused by molding, it was not possible to mold a single-piece structure, and a complicated construction method was required in which a large number of cooling pins were interposed between the inner and outer circumferential walls that had been molded into a predetermined shape.
本発明は、このような実情に鑑みなされたもの

2 is made of heat-resistant and corrosion-resistant metal such as stainless steel, Hastelloy X, and HA188, and the filling member 11
The cooling pin is approximately the same length as the thickness of the cooling pin. A large number of insertion holes 11a are formed in the filling member 11 in a grid pattern, and the cooling pins 12 are respectively inserted into each of the insertion holes 11a. Further, the upper and lower surfaces of the filling member 11 excluding the insertion hole 11a are plated with chromium (Cr) or nickel (Ni) (not shown), which will be described later.
In addition to preventing mutual diffusion of alloy elements between the filling member 11 and the outer peripheral wall (described later), the filling member 11
This prevents contamination due to oxidation, etc.

Seal by attaching etc. However, when sealing the outer periphery during TIG welding, it is necessary to vent residual gas between the stacked members.

HIP (Hot Isostatic Pressing) using a high temperature isostatic press that processes for several hours under 1000 to 1200 atmospheres
After processing, the cooling pin 12 and the inner and outer peripheral walls 13, 14
Diffusion bonding is performed between the filling member 11 and the inner and outer peripheral walls 13 and 14. Furthermore, the diffusion bonding between the inner and outer peripheral walls 13 and 14 and the filling member 11 is as follows:
The plating layer suppresses the diffusion of main alloying elements such as chromium and nickel from the inner and outer peripheral walls 13 and 14, as well as the diffusion of carbon and other substances from the filling member 11. As a result, the interdiffusion of alloying elements and poor quality due to high temperature and high pressure treatment are suppressed. Generation of an altered layer is prevented. After that, a solution treatment is performed for several minutes to several hours, and the carbides precipitated by the HIP treatment are dissolved into a solid solution and the bonded portion is subjected to a diffusion treatment.

る。 Next, as shown in d, the outer peripheral seal portion is cut and removed, and cooling air inflow holes 16 and 17 are bored in the inner peripheral wall 13 and the outer peripheral wall 14. Thereafter, it is molded into a predetermined shape as shown in e. This forming process may be performed before forming the air inflow holes 16 and 17. Since both peripheral walls 13, 14 and the cooling pin 12 are supported by the filling member 11 in this manner, no local deformation, cracks, or other molding defects occur. Also, surrounding wall 1
3, 14, since the cooling pin 12 and the filling member 11 are integrally connected, the molding operation can be carried out in the same manner as the ordinary molding process of a flat plate, and the molding operation is easy.

In this embodiment, the component members 18a and 18b are divided into two parts, but they may be molded without being divided in this way, and are not limited to the embodiment.
