Beijing-based Lingkong Tianxing Technology, also known as Space Transportation, has successfully tested a prototype aircraft capable of reaching Mach 4, which is equivalent to approximately 4,930 km/h. This achievement places the company’s technology at twice the speed of the Concorde, which was one of the most iconic supersonic passenger jets, capable of flying at around 2,150 km/h. This leap in speed represents a significant advancement in supersonic aviation, heralding a new era of ultra-fast travel for both civilian and potential military applications.

The legacy of supersonic travel: Concorde

The Concorde, which operated from 1976 until 2003, was a marvel of 20th-century engineering. It could fly at twice the speed of sound, reducing transatlantic flight times to around three and a half hours. However, high operating costs, limited seating capacity, and concerns over environmental impacts such as the sonic boom eventually led to its retirement.

The sonic boom, a loud noise generated by an aircraft traveling faster than the speed of sound, often led to flight restrictions over populated areas, which limited the Concorde’s route options. Despite its challenges, the Concorde symbolized innovation and luxury, paving the way for future advancements in supersonic travel.

Space Transportation aims to build upon this legacy by introducing a more sustainable and versatile solution to supersonic aviation. The development of the Yunxing aircraft could potentially overcome the limitations that led to the Concorde’s downfall, addressing both efficiency and environmental issues.

Introducing Yunxing: supersonic speed meets VTOL

The Yunxing aircraft, currently being developed by Space Transportation, promises to revolutionize air travel by drastically reducing long-haul flight times. The Yunxing is designed to fly the distance between Beijing and New York City in just two hours a flight that typically takes around 13 to 14 hours with conventional aircraft. Such a reduction in travel time could transform international business, tourism, and even geopolitical dynamics by making long-distance trips far more accessible and practical.

In addition to its incredible speed, the Yunxing features Vertical Take-Off and Landing (VTOL) capabilities. This means that the aircraft can take off and land vertically, similar to helicopters, which can greatly expand the number of locations from which it can operate. This capability is particularly valuable for military applications, where remote or unprepared landing sites are often needed. Moreover, VTOL reduces the reliance on large airports, opening possibilities for urban air mobility and improving accessibility to remote regions.

The Yunxing will also cruise at a remarkable altitude of 20,000 meters, nearly twice the altitude of typical passenger jets such as the Boeing 747. This higher cruising altitude means reduced air resistance, enabling faster and more fuel-efficient travel. Moreover, flying at higher altitudes avoids much of the turbulence that is common at lower levels, providing a smoother experience for passengers.

Supersonic aviation and environmental concerns

A key challenge for the future of supersonic flight is mitigating the environmental impact. Supersonic jets like the Yunxing will need to address the issues that plagued earlier efforts, including the Concorde. One of the most critical considerations is the fuel efficiency of the aircraft, as higher speeds typically demand higher fuel consumption.

Space Transportation has been investigating innovative solutions, such as sustainable aviation fuel (SAF) and aerodynamic improvements, to minimize carbon emissions and reduce the overall environmental footprint of supersonic travel.

Another crucial concern is managing the sonic boom effect. Traditional supersonic aircraft, like the Concorde, were notorious for generating loud sonic booms, which posed issues for overland flight. Engineers are now focusing on techniques to minimize or even eliminate the sonic boom known as “low-boom” technology which would make supersonic jets more acceptable for overland commercial flights. NASA’s X-59 QueSST is an example of an experimental aircraft designed to address this challenge, and it is likely that some of these technologies will influence Yunxing’s design as well.

The future of supersonic flight: 2027 and beyond

Space Transportation has ambitious plans for the future. They intend to complete a full-size prototype of the Yunxing aircraft, with a first test flight targeted for 2027. If successful, this will mark the beginning of a new era in aviation one where supersonic and even hypersonic travel become accessible not only to the ultra-wealthy but also potentially to a broader range of passengers.

The company was founded in 2018 with the express goal of reducing the costs associated with space exploration, and their experience includes planning large-scale flight projects and conducting environmental testing for extreme conditions. This experience positions them well to overcome the engineering challenges associated with supersonic travel.

If Yunxing’s development goes as planned, the aircraft could redefine air travel, providing a competitive alternative to conventional airlines for long-haul routes. Beyond civilian use, the aircraft’s capabilities also have potential military applications, including rapid troop deployment and reconnaissance. Such applications could significantly change military strategy, allowing for rapid global response times.

A new dawn for high-speed aviation

With Space Transportation’s efforts in developing the Yunxing aircraft, the dream of accessible supersonic travel is closer to becoming a reality. By building on the lessons learned from the Concorde and integrating new technologies such as VTOL and advancements in aerodynamics, Yunxing aims to address both the economic and environmental challenges of supersonic flight. Should their plans succeed, the two-hour Beijing-to-New York journey might become a common reality by the end of this decade, fundamentally altering how we think about time and distance in air travel.
