The TQ-12 ( Chinese : 天鹊-12 ; pinyin : Tiānquè-12 , lit. Sky Lark 12 ) is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen (methalox) developed by LandSpace . TQ-12 is the first Chinese liquid rocket engine developed with private funding. The engine has been designed to produce 670 kilonewtons (150,000 lbf ) of thrust at sea level.
4-622: The engine passed its first powerpack test including the turbopump , valves, ignition components , and the gas generator at a LandSpace facility in Huzhou on March 25, 2019. The engine's first full assembly was delivered in May 2019, and a hot fire test was successfully conducted the same month. The engine passed its first 200 second duration variable thrust test on October 26, 2019. A series of 400s hot fire tests were conducted in January 2021 and
8-453: The 2nd launch of Zhuque-2 was successful and the payload reached orbit. This rocketry article is a stub . You can help Misplaced Pages by expanding it . Powerhead (rocket engine) A liquid rocket engine powerhead (or powerpack ) is the turbopumps, preburners, and all the requisite equipment for a non-pressure-fed rocket engine cycle rocket engine, minus the combustion chamber and the expansion nozzle.

12-568: The first-stage engine assembly for LandSpace's Zhuque-2 rocket was completed in February 2021. The launch vehicle first stage consists of four TQ-12 engines providing a takeoff thrust of 268 tons. 37 TQ-12 family engines had been built by LandSpace as of July 2022, with cumulative hot fire test duration of more than 20,000 seconds. A record-breaking 3357 seconds of hot fire time were accumulated by one engine over 11 firings. In August 2022, LandSpace successfully tested an improved TQ-12A. Compared with
16-451: The original TQ-12, the engine thrust is increased by 9%, the specific impulse is increased by 40 m/s, and the weight is reduced by 100kg. On December 14, 2022, Zhuque-2 completed its maiden flight. Four TQ-12 engines powered the first stage, which performed normally during the flight. However, the TQ-11 vernier engines used in the second stage failed, and the rocket was lost. In July 2023,
