Engine combustion chamber with outlet flow preswirl

The invention relates to an engine combustion chamber with outlet flow pre-swirl. The engine combustion chamber comprises a casing, a flame tube and a fluid director. One end of the containing cavity is provided with an inlet, and the other end of the containing cavity is provided with an outlet. The flame tube is arranged in the containing cavity. A front fluid director is arranged at the inlet, and/or a rear fluid director is arranged on the tube wall of the flame tube; the front fluid director and the rear fluid director are both used for enabling incoming flow of the outlet to flow into the turbine guider or directly flow into turbine blades at a certain angle with the axis direction of the engine. According to the fluid director, gas at an outlet of an engine combustion chamber can flow into the turbine guider or directly flow into turbine blades in the preset direction, so that the load of the turbine guider is greatly reduced, the consistency and the strength design of the turbine guider can be reduced
