High-pressure-bearing flow-equalizing mixing collector and combustion device

According to the collector, an inlet flange and a collector shell are integrally machined and produced as a whole, the machining process advantages of additive manufacturing are fully played, meanwhile, the design of a large-fillet gradually-changed reducing inlet flange is adopted, and the flow-equalizing mixing effect is improved. The flow uniformity of a flow field in the collector is greatly improved; a reinforcing rib structure is arranged at the position of the inlet flange and the collector body, and a large-fillet transition edge is adopted at the transition position of the reinforcing rib, so that the pressure-bearing performance of a product is greatly improved; the collector adopts a barrel-shaped structure, so that the volume of a propellant cavity is reduced, the length in the direction of an inlet flange is reduced, and the structural arrangement of an engine is facilitated; the structural design of multiple rows of flow equalizing holes is adopted in the collector, so that the flowing uniformit
