Scientists Make Development That Facilitates Rockets To Orbit Longer

Reportedly, Chinese scientists have made advancement in cryogenic rocket engine technology that could expand the orbital duration of rockets from a mere few hours to 30 Days, offering support for China’s prospect deep space exploration. The cryogenic rocket engines are specifically designed to function at exceptionally low temperatures. They utilize non-polluting and non-toxic propellants—like liquid oxygen and liquid hydrogen—that are more cost-efficient than others. The engine has been extensively utilized in national and international launch vehicles, as well as China’s Long March-7 and Long March-5 carrier rockets.

Nevertheless, most of these rockets could orbit just for a few minutes or hours. An expanded orbital span has confused the aerospace industry for a long time. Researchers from the CALT (China Academy of Launch Vehicle Technology) have advanced two insulating materials that could decrease propellant evaporation loss and maintain rockets in flight for a longer time than before. As per to Zhang Shaohua—research team’s member—a cryogenic rocket would face a serious thermal environment when it soars in orbit, which would cause lots of propellant evaporation, speed up propellant loss and decrease the time in orbit. Additionally, when a rocket is flying, its engine would drive out the exhaust gases to keep pressure equilibrium in the propellant storage tank. Nevertheless, under the microgravity surroundings gas, space, and liquid cryogenic propellant would be mixed, thus, a large quantity of liquid propellant would also be released during engine exhaust.

On a related note, China gained new flexible liftoff abilities with first sea launch. In recent time, China effectively launched a Long March 11 rocket from a sea launch base, bringing its budding space program flexible and new launch capabilities. Seemingly, the Long March 11 solid propellant light liftoff vehicle was released from a mobile launch base in the Yellow Sea. The satellites included Bufeng-1A and Bufeng-1B, designed by the CAST (China Academy of Space Technology) to check ocean wind fields and advance supervising, Xiaoxiang-1-04.
