PARIS — A major arm of China’s state-owned space contractor is looking at developing a series of partially and fully-reusable launch vehicles apparently in response to SpaceX’s Starship.
A paper published in the journal Aerospace Technology outlines plans under consideration by the Shanghai Academy of Spaceflight Technology (SAST) for a number of launch vehicles with varying diameters and clusters of methalox engines.
A first generation of three launch vehicles with reusable first stages would have diameters of 3.35, 4.0 and 7.0 meters, powered by clusters of five, seven-to-nine and 9-22 “Longyun” 70-ton-thrust engines. Second stages would use vacuum-optimized versions of the engine.
The 3.35m version is to be capable of lifting 2,500 kilograms to a 700-kilometer sun-synchronous orbit (SSO), while the 4.0m variant—a size chosen to meet the maximum which can be transported to China’s inland launch sites—could launch up to 6,500 kg of payload to a similar orbit.
The 7.0 meter version is planned to be able to launch more than 20,000 kg to 700 km SSO, while requiring new launch facilities and an offshore platform for recovering the first stage.
