On September 23, 2021, the engine successfully underwent its first semi-system test. [7] [8] The YF -90 engine is one of the key technologies for China's deep space exploration ambitions. [9] In 2023, CASC plans to conduct more tests on the YF-90 engine, as well as on its first-stage counterpart, the YF-130 engine. The YF-130 is a liquid ...
Long March 9 (Chinese: 长征九号火箭, LM-9 or Changzheng 9, CZ-9) is a Chinese super-heavy carrier rocket that is currently under development. [1] [2] It is the ninth iteration of the Long March rocket family, named for the Chinese Red Army's 1934–35 Long March campaign during the Chinese Civil War.
Zhuque-2 has a liftoff weight of 216 tonnes and uses 4 TQ-12 methalox engines in the first stage, each with a thrust of 67 tonnes-force (660 kN). [3] [4] The second stage uses one vacuum-optimized TQ-12 with a thrust of 80 tonnes-force (780 kN) in combination with a TQ-11 engine (8 tonnes-force (78 kN) thrust), which acts as a vernier thruster.

The Long March 10, previously known as the "921 rocket", [39] is under development for crewed lunar missions. The nickname "921" refers to the founding date of China's human spaceflight program. Like the Long March 5, it uses 5-meter (16.4 ft) diameter rocket bodies and YF-100K engines, although with 7 engines on each of 3 cores.
Long March 2 was the original model in the Long March 2 rocket family, which was derived from China's first ICBM, the DF-5. The development work began in 1970. The first rocket was launched on November 5, 1974, [1] but the launch failed. After the failed first launch of Long March 2, its design was slightly modified and designated as Long March 2A.
LandSpace completed the first engine hot firing test for TQ-11 on November 3, 2019, and the engine passed a 1500 second test in 2020. [2] [4] On December 14, 2022, Zhuque-2 completed its maiden flight. The TQ-11 engines used in the rocket's second stage failed, resulting in mission failure.
Sky Lark 15) is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen under development by Landspace. The most recent version of the TQ engine family, the TQ-15A, is intended to power the second stage of LandSpace's upgraded Zhuque-2 rocket.
