Abstract

The invention provides an internal combustion wave rotor exhaust mixing device based on vane guide flow and pressure relief, which includes a wave rotor, a sealing plate and an exhaust port. The wave rotor is provided with a plurality of wave rotor channels, and the wave rotor is arranged against the sealing plate. One end is airtightly connected with the sealing disk, and the sealing disk is provided with an arc-shaped hole, and the side of the sealing disk away from the wave rotor is provided with an exhaust port matching the arc-shaped hole, and there are multiple exhaust ports in the exhaust port. The guide vane is formed into several airflow channels. There are multiple pressure relief holes on the guide vane. The distance between the ends of two adjacent guide vanes close to the sealing disk is the same, and the distance between the ends of two adjacent guide vanes away from the sealing disk is along the wave rotor. The direction of rotation becomes progressively larger. The invention adopts guide vanes with pressure relief holes to divide the exhaust port into several airflow channels, adjust the exhaust volume flowing through each airflow channel through the throat area and blade shape, realize effective mixing of exhaust gas, and promote exhaust The gas pressure in the port is uniform, and it can better cooperate with turbine components and so on.

Description

technical field [0001] The invention relates to the technical field of exhaust devices for unsteady propulsion systems, in particular to an internal combustion wave rotor exhaust mixing device based on blade guide flow and pressure relief. Background technique [0002] For a long time, the isobaric combustion mode based on the "Brayton cycle" has occupied an absolute dominant position in the propulsion system field due to its stability. It is very difficult to greatly improve, and a thermal cycle method with higher thermal efficiency must be explored. In this context, the constant-volume supercharged combustion mode based on the Humphrey cycle stands out and has received extensive attention and research from scholars at home and abroad. Among them, the internal combustion wave rotor technology is one of the representative solutions. Since the internal combustion wave rotor adopts unsteady increasing The pressure combustion mode has higher thermodynamic efficiency. In additi...
