Assembly welding of the booster oxidizer tank for propulsion system test-firing, the first structural product of LM-7, has been performed at Capital Aerospace Machinery Corporation, CALT. The 2.25m diameter oxidizer tank is only 0.17cm in thinness in the thinnest area and is nearly 13m in length increased from the current 4.5m, which is the展开更多

This paper will introduce the features and new technology of LM-7, LM-5 and LM-11 launch vehicles, which are China's new typical generation Launch vehicles.展开更多
