HELSINKI \u2014 Chinese launch startup Landspace says it has completed a long-duration full-system hot-fire test of its new 220-ton-class methane rocket engine for new-generation launchers.<\/p>\n
Landspace made China\u2019s first orbital booster recovery attempt<\/a> in December 2025 with the debut launch of its stainless steel Zhuque-3 rocket. While the second stage with a mass simulator payload successfully reached orbit, the first stage failed shortly after initiation of the landing burn.<\/p>\n The company is planning another attempt for the second quarter<\/a> of this year and aims to demonstrate reuse in the fourth quarter, but is meanwhile also making progress on an engine to power new, larger and more powerful launchers.\u00a0<\/p>\n Landspace announced<\/a> March 6 that it had recently completed a long-duration test firing of its BF (Lanyan, meaning \u201cBlue Flame\u201d) full-flow staged combustion (FFSC) cycle methane-liquid oxygen rocket engine. The test followed more than 100 full-system ignition tests since the program\u2019s first integrated hot fire in May 2025.<\/p>\n The BF engine is designed to produce roughly 220 metric tons of thrust and is intended as a core propulsion element for Landspace\u2019s next-generation heavy-lift launch vehicles. The company said the latest test validated the engine\u2019s integrated systems and demonstrated continued progress in key technologies required for high-performance methane propulsion.<\/p>\n \u201cThese advances further improve the engine\u2019s technical maturity and lay a solid foundation for future development. The BF engine will serve as a critical propulsion building block for the next generation of large to heavy-lift launch vehicles, supporting the development of high-efficiency and reusable heavy-lift propulsion systems,\u201d the Landspace statement read.<\/p>\n The FFSC architecture offers higher propellant utilization efficiency, increased thrust-to-weight ratio and improved engine lifetime compared with more traditional cycles. However, the design also brings significant engineering challenges, including complex system interactions, high internal pressures and demanding thermal environments. This architecture is, however, seen as the future of partially and fully-reusable heavy-lift launch vehicles. The most prominent example is SpaceX\u2019s Raptor engine, developed to power the company\u2019s Starship launch system.\u00a0<\/p>\n Landspace did not disclose details of the test, such as duration of the hot fire and the thrust levels demonstrated. A short clip of the test appeared on China Central Television news reports.<\/p>\n The company already operates the Zhuque-2 and Zhuque-3 rockets. The latter has secured the company contracts<\/a> to launch batches of satellites for the national Guowang communications megaconstellation. Successful development of the BF engine would further cement Landspace\u2019s position in a crowded Chinese commercial launch ecosystem. The company also saw its application for an initial public offering accepted<\/a> by the Shanghai Stock Exchange\u2019s STAR Market in late December, with Landspace seeking to raise around $1 billion (7.5 billion yuan).<\/p>\n China\u2019s state-owned main space contractor, the China Aerospace Science and Technology Corp. (CASC), is alsodeveloping an FFSC engine<\/a>. Clusters of these engines, sometimes referred to as the YF-215, are expected to power the first stage of China\u2019s Long March 9<\/a> super heavy-lift launcher. Landspace\u2019s commercial rival Space Pioneer has also stated its intention to develop an FFSC engine, while newer, much less established entrants Welight<\/a> and Arktech<\/a> have also put forward concepts for FFSC-powered rockets.<\/p>\n The country\u2019s annual political sessions are currently ongoing in the capital Beijing, with a draft of the 15th Five-year plan being debated ahead of expected approval. The plan will set national priorities and strategic goals for the period 2026-2030. The draft notes the development of reusable heavy-lift launch vehicles as a priority. Boosting launch capabilities will be crucial to achieving other noted space sector objectives<\/a>, such as satellite internet constellations and a lunar research station<\/a>.<\/p>\n \n\tRelated<\/p>\n","protected":false},"excerpt":{"rendered":"HELSINKI \u2014 Chinese launch startup Landspace says it has completed a long-duration full-system hot-fire test of its new…\n","protected":false},"author":2,"featured_media":333373,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[1657,85,46,20166,60306,141,3443,145],"class_list":{"0":"post-333372","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-china","9":"tag-il","10":"tag-israel","11":"tag-landspace","12":"tag-reusable-launch-vehicles","13":"tag-science","14":"tag-sn","15":"tag-space"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/333372","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=333372"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/333372\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/333373"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=333372"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=333372"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=333372"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
