Emissions cooling is another type of flow cooling. Unlike the regeneration cooling, the cooling agent used to discharge cooling agents does not enter the combustion room to participate in the combustion after cooling and absorbing the heat. Instead, it is discharged. Directly discharged coolant will reduce the thrust room ratio, so it is necessary to minimize the flow of cooling agent used for discharge of cooling, and at the same time, only discharge cooling is used only in the relatively not severe nozzle exit section. There is also a radiation cooling. The heat flow is passed to the thrust room by the combustion product, and then the thrust room wall wants the surrounding space to radiate heat dissipation. Radiation cooling is characterized by simple and small structural quality. It is mainly used in the extension section of the large nozzle and a small thrust engine thrust room with high temperature resistance. When cooling indoor cooling, it is a liquid or gas protective layer with relatively low temperature on the surface of the indoor wall of the thrust room to reduce the heat flow passed to the wall of the thrust room, reduce the temperature of the wall surface, and achieve cooling. Internal cooling is mainly divided into three methods: internal cooling (shielding cooling), membrane cooling and sweating cooling. After the thrust room adopts internal cooling measures, because the temperature of the protective layer needs to be reduced, the hybrid ratio near the wall surface of the burning room is different than the best mixed ratio (in most cases the near wall layer of fuel rich), resulting in a hybrid ratio along the edge of the edge of the mixed ratio. The horizontal section of the combustion chamber is unevenly distributed, which reduces the combustion efficiency to a certain extent. Film cooling is similar to shielding cooling. It is to cool the liquid indoor wall by establishing a uniform and stable cooling liquid film or gas film protective layer near the inner wall surface. Instead, it is provided by a special cooling belt. The cooling belt is generally arranged on a cross -section of the combustion room or a nozzle convergence section. There are several cooling bands in the length of the burning room. In order to improve the stability of the membrane, when the cooling agent is often cooled by sweating by the gap or small pores on each cooling belt, the indoor wall or part of the inner wall of the thrust is made of porous materials, and its pore diameter is tens of microns. Multi -porous materials are usually sintered with metal powder or suppressed by metal mesh. In this case, the micro -holes in the material are evenly distributed as possible, and the number of holes in the unit area increases. The liquid coolant penetrates into the inner wall and establishes a protective film to reduce the heat flow density passed to the wall. When the flow of liquid coolant for sweating and cooling is higher than a certain critical value, the liquid film is formed near the indoor wall of the thrust. When the cooler flow is lower than the critical value flow, the temperature of the inner wall will be higher than the boiling point of the coolant under the current pressure, and some or all coolant evaporates to form a gas film. In addition to the above thermal protection, there are other heat protection methods such as: ablation, heat insulation cooling, hot -melt cooling, and composite protection of the room wall. 3 The thermal protection solution of high -pyreces gas generator combines the above methods combined with the actual situation to obtain the thermal protection method of the high -pyretee gas generator. The combustion room of the high gas generator is different from the liquid rocket engine, which eliminates the previous thrust room to make its structure easier and effective. Then, the heat protection involved is the thermal protection part of the burning room wall. As the fuel enters the combustion room, quickly decomposes and releases a lot
