China's commercial reusable launch vehicle sector continues to make steady progress, as a company announced on Friday that it had completed a long-duration test firing of an engine for a large recoverable carrier rocket.
Deep Blue Aerospace, a commercial space startup based in Wuxi, east China's Jiangsu Province, said it recently completed a 100-second static-fire test of its Thunder-RS engine, a 130-tonne-class liquid-oxygen kerosene engine designed for the company's large reusable rocket, Nebula-2.
The test reached 1,297.5 kilonewtons of thrust, or about 132.3 tonnes. The company said multiple short-duration test firings had been conducted previously to evaluate engine performance, with no anomalies recorded.
The recent 100‑second run was the engine's first crossing of that steady‑state duration threshold, serving as a comprehensive verification of its performance, the company said.

Rocket reusability can greatly cut launch costs and boosts launch frequency, making it key to achieving large-scale, routine access to space.
China launched the reusable rocket Zhuque-3 on Wednesday morning, achieving its first recovery of a rocket's first stage on land, marking the country's first successful land-based recovery. This mission followed the successful sea-based net recovery of the Long March-10B's first stage on July 10.
More models of Chinese reusable rockets are scheduled to conduct tests this year.
。湖南省委常委、长沙市委书记吴桂英指出,长沙深入实施“强省会”战略,做大做强科创平台,全力建设海归小镇。下一步,将以此次海归小镇揭牌为重大契机,进一步加强与欧美同学会的深度对接,着力打造宜居宜业、产城融合、生态友好、合作开放的国际化小镇范本。

B | 欧美同学会副会长曹卫星表示,长沙是欧美同学会10个海归小镇申建地之一,自2020年11月启动申建工作以来,围绕“智能制造”的产业定位,加强规划设计、完善基础配套、加大政策支持、强化项目导入,已通过两个阶段的专家评审,并按照所提评审建议持续推进各项工作,申建工作取得明显成效。海归小镇围绕“一个小镇一个产业”的基本定位,以地方主导性产业发展为核心,以市场化的运营模式,有相对吸引力的营商环境和支持政策,是由欧美同学会与有关地方政府共同创建的攻克“卡脖子”科技的策源地、“专精特新”企业的孵化地、战略性新兴产业的创新高地。(完)返回搜狐,查看更多责任编辑:
