民营航天企业“星际荣耀”试制成功液氧甲烷发动机燃气发生器组件

太空来电2018/06/02 01:19:13太空来信

北京星际荣耀空间科技有限公司5月31日发布消息称，该公司15吨级液氧甲烷发动机配套的燃气发生器装置，于当日在北京完成点火试验，试验取得成功。

液氧甲烷组合是目前最有前景的燃料组合，它有效的克服了液氧煤油发动机的积碳问题，有利于发动机的多次重复使用。该燃料组合还具有比冲大，体积能量比合理，燃料获取、储存和处理方便等特点。目前，我国国营航天机构航天科技集团六院于2011年完成液氧甲烷发动机关键技术研发，2013年实现了60吨级发动机的全系统测试。民营航天企业北京蓝箭空间科技有限公司也已完成10吨级液氧甲烷发动机的试制，正在攻关百吨级发动机。

据“星际荣耀”披露，5月31日的试验验证了燃气发生器工作稳定性，考核了变工况适应性和点火器点火可靠性，为后续燃气发生器产品状态定型提供了工程依据。另外，该燃气发生器完全采用3D打印制造，试验证明该制造工艺满足实际需求。试验系统采用预增压储罐，两种推进剂通过喷注器雾化，通过点火器点燃产生高温燃气，通过弯管喉部喷管控制燃气输出参数(压力、温度)，满足涡轮泵做功介质要求。
