Rotating detonation combustion engine with fuel injectors
A recently granted patent (Publication Number: US11970994B2) discloses an innovative engine design featuring a longitudinal wall that defines a gas flowpath. The engine includes an inner wall assembly that extends into the gas flowpath, creating a rotating detonation combustion region in the first portion of the flowpath. This combustion region is strategically positioned upstream of the inner wall assembly and adjacent to the longitudinal wall. The inner wall assembly also facilitates an additional combustion region downstream of the rotating detonation combustion region. Fuel injection is achieved through two injectors, with the first injector supplying fuel to the rotating detonation combustion region and the second injector providing fuel for deflagrative combustion in the additional region.
Furthermore, the engine design includes specific features such as fuel injection ports, a sheltered cavity for detonation wave propagation, and an exhaust nozzle distinct from the combustion section. The longitudinal wall of the engine defines various sections, including an inlet section for admitting oxidizer and a combustion section where the inner wall assembly is located. The engine's unique configuration allows for efficient fuel combustion and flow control, with the inner wall assembly extending to a specific depth within the gas flowpath. Additionally, the engine's rectangular cross-section design, with a width and height defining a square area, contributes to its overall performance and functionality. Overall, this patented engine design showcases advancements in combustion technology and flow dynamics, potentially offering improved efficiency and performance in various applications.
