On September 1st, Xingsuo Technology (Beijing) Co., Ltd. announced a significant advancement in aerospace engineering—the successful completion of the injector atomization test for the oxygen-rich pre-combustion chamber of its Mammoth One (MM-1) engine. This test marks a pivotal moment in the development of the full-flow refueling cycle engine, propelling the project into an accelerated phase of innovation.
Accelerating Engine Development
The success of the injector atomization test eliminates major roadblocks, paving the way for future verification of core components, including pre-combustion chamber extrusion tests and turbo pump joint regulation. This achievement is crucial for Xingsuo Technology as it strives to master the complexities of developing high-thrust, high-performance, and reusable liquid rocket engines.
The Significance of Injector Performance
As an integral part of the full-flow refueling cycle engine, the injector’s efficiency directly impacts the engine’s reliability and adaptability under various working conditions. Specifically, the oxygen-rich pre-combustion chamber is engineered to effectively combust highly oxygenated fuels within a confined space, producing a steady output of oxygen-rich gas to power the turbo pump.
Achieving optimal performance in the combustion structure and secondary blending scheme for the pre-combustion chamber has proven to be a significant engineering challenge. To tackle these complexities, the Xingsuo Technology team engaged in extensive design and simulation calculations based on the combustion and blending mechanisms of a liquid oxygen/methane propellant. Their cumulative efforts have led to the initial convergence on an effective injector design scheme.
Bridging the Gap Between Theory and Engineering
The recent liquid flow atomization test represents a substantial transition from theoretical research to practical engineering application. Drawing from robust preliminary studies, the technical design team explored multiple configuration solutions for the oxygen-rich pre-fueled chamber’s gas-liquid injectors. The results will provide valuable data, enabling optimization of injector design and simulation verification of nozzles for ongoing development.
Xingsuo Technology emphasizes that this successful test forms the basis for in-depth refinement of the injector design. The testing accurately calibrated the multi-phase flow simulation model, significantly enhancing the predictive capabilities of their design tools. This solidifies their path toward faster iterative design for the Mammoth One (MM-1) engine, ensuring a robust foundation for upcoming component designs and testing phases.
