Abstract

The invention discloses a small-sized annular combustion chamber with high-capacity heat intensity, which comprises a combustion chamber casing, an oil supply component, an outer flame tube, an inner flame tube, a high-pressure turbine guider, an oil thrower wheel and an igniter, wherein the oil supply component is fixed on the combustion chamber casing; and the outer flame tube, the inner flame tube and the high-pressure turbine guider are fixedly connected with the combustion chamber casing. As an oil thrower wheel type baffling combustion chamber is adopted by the annular combustion chamber, and a radial combustion way is used, the axial size of the combustion chamber can be reduced, the size of the combustion chamber is reduced, and the heat capacity intensity of the combustion chamber can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of aerospace machinery design and manufacture, in particular to a small-sized annular combustion chamber with high heat capacity and strength. Background technique [0002] The heat capacity of the combustion chamber is defined as the heat released per hour by the combustion of fuel per unit volume in the combustion chamber under unit pressure, which is an indicator of the compactness of the combustion chamber. The high heat capacity indicates that the volume of the combustion chamber required to burn the same flow of fuel is small, so it is small in size and light in weight. In small gas turbine engines, a baffled combustor with an oil flinger is usually used in order to reduce the size of the combustor and increase its heat capacity. In this kind of combustion chamber, the fuel is supplied to the main shaft of the engine and flows to the oil throwing pan installed on the main shaft. . It can ensure good...
