EXHAUST MIXER FOR WAVE ROTOR ASSEMBLY

摘要

A wave rotor assembly includes a wave rotor combustor and an exit duct. The wave rotor combustor includes an aft plate formed to include an exit port and a rotor drum mounted for rotation relative to the aft plate. The rotor drum is formed to include a plurality of rotor passages arranged to align with the exit port during rotation of the rotor drum. The exit duct is coupled to the aft plate and defines a passage arranged to receive exhaust gasses flowing through the exit port.

1. A wave rotor assembly comprising
a wave rotor combustor including an aft plate formed to include an exit port that extends circumferentially along an arc about a central axis of the wave rotor combustor and a rotor drum mounted for rotation relative to the aft plate about the central axis, the rotor drum formed to include a plurality of rotor passages that extend along the central axis and are arranged so that the rotor passages align with the exit port at predetermined intervals when the rotor drum rotates about the central axis to allow exhaust gasses in the rotor passages to flow through the exit port, an exit duct coupled to the aft plate that defines a duct passage arranged to receive the exhaust gasses flowing through the exit port, and an exhaust mixer located in the duct passage and arranged to circumferentially redirect relatively-high velocity exhaust gasses received by the exit duct toward relatively-low velocity exhaust gasses received by the exit duct so that the relatively-high velocity exhaust gasses are mixed with the relatively-low velocity exhaust gasses in the duct passage.
