Technical Traceability Report for Domestic Liquid Oxygen Methane Engine R&D: Priority and Contribution Analysis Based on Bian Zhenfeng's January 2026 Scheme

AbstractThis report conducts a systematic technical traceability and contribution analysis on the major engineering breakthroughs of China's liquid oxygen methane (LOx/CH₄) rocket engine from January to February 2026. The Optimization Scheme for Process Adaptation of Domestic Small-Scale High-Efficiency Liquid Oxygen Methane Test Engine, publicly deposited by the independent researcher Bian Zhenfeng on Zenodo on January 20, 2026 (DOI: 10.5281/zenodo.18313706), features a high degree of technical homology with the subsequent R&D achievements released by China Aerospace Science and Technology Corporation (CASC) and commercial aerospace enterprises in terms of core design principles, process routes and performance index systems. By constructing a complete time evidence chain and comparing key technical nodes, this report verifies that the scheme has clear temporal priority and technical leadership in critical directions such as integrated 3D printing manufacturing, mature process adaptability, and thermal management system optimization. This report provides verifiable documentary evidence for the academic contribution of this original technical scheme, and lays a factual foundation for subsequent intellectual property claims, technological achievement transformation and engineering cooperation. 中文摘要 摘要本报告旨在对2026年1月至2月期间中国液氧甲烷及相关火箭发动机领域的重大工程突破进行技术溯源与贡献分析。独立研究者卞振峰于2026年1月20日通过Zenodo平台公开存证的《国产小型高效液氧甲烷试验发动机工艺适配优化方案》(DOI: 10.5281/zenodo.18313706),其核心设计原则、工艺路线与性能指标体系,与同期中国航天科技集团、商业航天企业的公开研发成果呈现高度的技术同源性。 报告通过构建完整的时间证据链,对比核心技术节点,证实该方案在“3D打印一体化制造”“成熟工艺适配性”“热管理系统优化”等关键方向上具有明确的时间优先权与技术引领性。本报告为该原创技术方案的学术贡献提供了可核验的文献证据,为后续的知识产权主张、技术成果转化及工程合作奠定了事实基础。
