What China’s Reusable Rockets Mean for Aerospace Engineering

China has successfully tested and landed a reusable rocket, signalling a significant step forward in their space ambitions. On 23rd June 2024, a liquid-fuelled launcher ascended to an altitude of 7.5 miles (12 km) from the Jiuquan Satellite Launch Center. This achievement places China in closer competition with pioneers in reusable rockets like SpaceX, who have revolutionised the space industry with their reusable rocket technology.

Reusable rockets, initially conceptualised during the Apollo era, have only recently become a game changer thanks to companies like SpaceX and Blue Origin. These rockets recover boosters intact rather than allowing them to crash into the ocean, drastically reducing launch costs and enabling economies of scale. This technology not only expands existing rocket fleets but also facilitates the creation of revenue-generating satellite constellations.

SpaceX’s Impact on Reusable Rocket Technology

SpaceX has led the way in reusable rocket development, reinvesting profits from their launch services back into innovation. Despite this, the full economic impact of reusable rockets has yet to be realised. Some analysts suggest that if SpaceX focused solely on launches, their cost of approximately $1,000 per kilogram could decrease even further.

The company’s emphasis on development over immediate profit has allowed them to push the boundaries of reusable rocket technology. Their advancements have set a high bar for other aerospace engineering firms and have sparked a global race to achieve cost-effective space travel.

China’s Strategic Move in the Space Race

As a major player in the launch business, China aims to dominate the space sector in the coming decades. The urgency to establish a strong presence in both heavy and small payload fields is driven by their current economic challenges and the need to stay ahead of the competition. The recent test flight represents a significant step in these efforts.

Developed by the Eighth Academy of the China Aerospace Science and Technology Corporation (CASC), the new rocket serves as a technology demonstrator for future, larger vehicles. Measuring 12 feet (3.8 metres) in diameter, the rocket is powered by three variable-thrust liquid oxygen/methane engines and features four folded landing legs with a specialised shock absorber system. This flight marked the first high-altitude test of a domestically built variable-thrust methane engine, with the rocket performing flawlessly through lift-off, acceleration, controlled descent, and landing.

The Future of Reusable Rockets

Looking ahead, China plans to launch larger reusable rockets in 2025, targeting an altitude of 43 miles (70 km). This ambitious goal reflects their commitment to advancing their aerospace capabilities and competing on the global stage.

The development of reusable rockets is not only a technological feat but also a strategic move in the highly competitive space industry. By achieving greater efficiencies and reducing costs, reusable rockets could revolutionise space travel and satellite deployment, paving the way for new opportunities in communication, exploration, and beyond.
