Patent number: 11970993Abstract: A Brayton cycle engine and method for operation. The engine includes an inner wall assembly and an upstream wall assembly each extended from a longitudinal wall into a gas flowpath. An actuator adjusts a depth of the detonation combustion region into the gas flowpath between the inner wall assembly and the upstream wall assembly. The engine flows an oxidizer through the gas flowpath and the inner wall captures a portion of the oxidizer. The engine further adjusts the captured flow of oxidizer via the upstream wall and flows a first flow of fuel to the captured flow of oxidizer to produce rotating detonation gases. The engine flows the detonation gases downstream and to mix with the flow of oxidizer, and flows and burns a second flow of fuel to the detonation gases/oxidizer mixture to produce thrust.Type: GrantFiled: September 27, 2022Date of Patent: April 30, 2024Assignee: GENERAL ELECTRIC COMPANYInventors: Sibtosh Pal, Steven Clayton Vise, Arthur Wesley Johnson, Clayton Stuart Cooper, Joseph Zelina
