AI Technical Summary
Traditional full-flow afterburning engines are complex in design, have high R&D costs, complex adjustment logic, non-compact structure, unstable combustion, and are difficult to achieve the requirements of deep variable thrust and stability.
It adopts a modular design, including a liquid oxygen pump, a methane pump, an oxygen-enriched gas generator, a fuel-enriched gas generator, a secondary regulating valve, and a combustion unit control valve, to achieve decoupled control of generator flow and mixture ratio. The flow is regulated by independently controlling the combustion unit and the secondary injection throttle valve, and it uses a chemical equivalence combustion unit and an independent igniter.
It simplifies design and simulation costs, improves combustion stability and thrust adjustment flexibility, enables deep throttling and rapid fault handling, has a compact structure, and reduces R&D difficulty and overall design complexity.
