Developers believe the approach could lower infrastructure requirements while supporting faster launch schedules for China’s expanding commercial space sector.<\/p>\n
Latest Videos From The technology ejects rockets using rapidly expanding high-pressure gas before igniting engines only after reaching a predetermined altitude overhead.<\/p>\n That sequence differs sharply from conventional hot launches where engines ignite directly on launch pads before the vehicle begins climbing skyward.<\/p>\n You may like<\/p>\n Because combustion occurs later in flight, scorching exhaust gases never strike the launch platform or surrounding support infrastructure below.<\/p>\n Traditional launch facilities require extensive protection systems because exhaust streams exceeding 3,000\u00b0C can damage structures rapidly during operations.<\/p>\n Launch towers and deep flame trenches therefore require substantial repairs and maintenance after missions involving repeated exposure to extreme temperatures.<\/p>\n According to the company, those requirements increase costs and slow launch frequencies whenever operators pursue swift response commercial missions.<\/p>\n \u201cIn commercial space launch scenarios requiring high frequency and rapid response, this incurs high time and financial costs, directly affecting launch pacing and response speed,\u201d the company said.<\/p>\n What to read next<\/p>\n Z-Trak Space believes eliminating those burdens could increase launch pacing while reducing dependence upon permanent launch infrastructure considerably over time.<\/p>\n China’s commercial sector sees cold launch technology as a possible advantage<\/p>\n The initiative combines efforts from Hunan based Zhiyu Aerospace Technology and Chiyang Space Power Technology Company through a recent collaboration agreement.<\/p>\n Z-Trak Space founder Zhang Zihan, who studied aerospace engineering at Hong Kong Polytechnic University, described the concept as potentially transformative.<\/p>\n Zhang said the method would “fundamentally change the model for small liquid-fuel launch vehicles” if implemented successfully at commercial scale.<\/p>\n The company also argued that supercritical CO\u2082 launches could reduce fuel use during lower altitude portions of flight operations.<\/p>\n Because supercritical CO\u2082 is non-toxic, developers also claim launches would avoid generating harmful emissions near ground facilities locally.<\/p>\n Z-Trak described the system as offering “high safety, low costs, clean environmental performance and low ablation” during launch procedures.<\/p>\n China’s commercial space industry recorded 50 launches during the previous year, representing more than half of national missions completed overall.<\/p>\n Whether CO\u2082 launches become commercially practical remains uncertain, although the proposal reflects experimentation occurring throughout China’s rapidly changing space industry.<\/p>\n Via SCMP<\/a><\/p>\n Follow TechRadar on Google News<\/a> and add us as a preferred source<\/a> to get our expert news, reviews, and opinion in your feeds.
