Why It Matters
A Chinese aerospace startup, Zhiyu Aerospace Technology, is developing a novel rocket launch system using supercritical carbon dioxide.
A Chinese aerospace start-up plans to launch a rocket using carbon dioxide, the same compound that gives Coca-Cola its fizz and bite.
Hunan-based commercial space firm Zhiyu Aerospace Technology announced on Monday that it was collaborating with another local tech company to apply “supercritical carbon dioxide cold-launch” technology to small launch vehicle systems.
Z-Trak Space, as the company is also known, said the cutting-edge method could “truly achieve low-cost, high-frequency, fast-response commercial launches”.
The new technology uses supercritical carbon dioxide – a fluid state of the gas held at or above its critical temperature and pressure – to generate high-pressure gas that expands instantaneously, effectively ejecting the rocket into the air.
Once the rocket reaches a designated altitude, its engines ignite in mid-air to begin normal flight, ensuring that scorching exhaust fumes never come into contact with the ground platform.
The partnership brings together Z-Trak Space – founded last year in the prefecture-level city Zhuzhou in China’s central Hunan province – and Chiyang Space Power Technology Company, according to a statement by Z-Trak on Tuesday.
