Chinese commercial space firm completes long-duration test of reusable rocket engine_我的网站
一 |
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.

二 | 而自10月9日以来，美国财政部已经三次购买阿根廷比索，据阿根廷经济学家估计总额约为4亿美元。 除此之外，美国财政部长贝森特上周还指出，正在安排美国的私营部门向阿根廷提供一笔200亿美元的贷款。 尽管美国不遗余力地“救火”，阿根廷比索周一仍然下跌。早盘交易中，美元兑阿根廷比索汇率下跌近1%至1476，创下盘中新低，随后有所回落。
三 | 分析人士表示，来自美国的支持未能平息阿根廷投资者对美元的需求，这些投资者正在为米莱在10月26日关键的中期选举中可能遭遇的糟糕结果而进行对冲。 周一，两月期阿根廷比索远期合约定价暗示，美元兑阿根廷比索汇率很可能升破1600，意味着新一轮的比索抛售。 仍不乐观 阿根廷投资者担忧，由于阿根廷央行的外汇储备不足，米莱很可能在中期选举后被迫贬值阿根廷比索。据经济咨询公司Invecq估计，阿根廷货币当局的流动储备仅为50亿美元，其中包括一笔国际货币基金组织的贷款。
四 | 而来自美国的救助将有效补充阿根廷央行的美元储备，但截至目前，美阿两国都未披露货币互换计划的细节。瑞银分析师Pedro Quintanilla-Dieck失望表示，两国政府只确认了市场已知的信息，并未提供其他细节，政策不透明性影响了市场的积极情绪。
五 | 除了金融上的援助之外，美国总统特朗普上周日表示，美国可能可以购买阿根廷的牛肉来帮助该国度过危机，同时降低美国的牛肉价格。特朗普还强调，阿根廷没有钱，什么都没有，正在为生存而战。 此前，美国政府因援助阿根廷而受到诟病，理由是美国政府目前正因为财政支出法案而停摆，同时阿根廷又抢夺了美国大豆的最大出口市场，令部分美国民众感到不满。
