A Chinese aerospace company has unveiled its prototype for a next-generation supersonic passenger aircraft capable of flying at Mach 4, twice the speed of the legendary Concorde. Sichuan Lingkong Tianxing Technology Co revealed the prototype, named Cuantianhou, or “Soaring Monkey,” in Chengdu, the capital of Sichuan Province, earlier this week.
The ambitious project is part of China’s push to revolutionize high-speed intercontinental travel, with the maiden flight of the Cuantianhou demonstrator scheduled for 2026. The test flight will focus on evaluating key metrics, including aerodynamics, heat-resistant materials, and the innovative power system.
Deng Fan, the company’s chief engineer, described the initiative as a major step forward in reviving supersonic commercial travel. “Supersonic passenger aircraft is making significant breakthroughs and a strong comeback. It has great potential to provide more economical and reliable high-speed flight services in the coming years,” he said.
A Leap into Near-Space Travel
Designed to operate in near space, a region between 20 and 100 kilometers above sea level, Cuantianhou is equipped with a state-of-the-art ramrotor detonation engine, combining cutting-edge rotor compressor, ramjet, and detonation technology. Dubbed the Jindou-400S, the engine is compact, weighing only 100 kilograms, yet capable of producing at least 4,000 newtons of thrust. This propulsion system will enable the aircraft to reach speeds of Mach 4.2, or approximately 5,000 kilometers per hour, nearly five times faster than conventional jets.
At 7 meters long and weighing 1.5 metric tons, the Cuantianhou prototype features a streamlined aerodynamic design to reduce drag and improve flight efficiency. Its journey will begin with a carrier rocket launching it to an altitude of 20 kilometers, after which it will continue to fly autonomously. Most of its travel will occur in near space, far above the altitude of commercial airliners but below orbiting satellites.
Despite its extreme speeds, Deng assured that passengers on future iterations of the aircraft will not experience harmful acceleration effects, highlighting the safety and comfort of the design.
Vision for the Future: Dasheng
If successful, the company plans to follow up with a larger, commercial-use supersonic aircraft named Dasheng, or “Monkey King,” by 2030. Inspired by the legendary hero of Chinese mythology, Dasheng is expected to revolutionize global air travel, cutting intercontinental flight times from over 10 hours to just two or three.
The development of supersonic airliners represents a return to the aspirations once embodied by the Concorde, the world’s first supersonic passenger jet. While Concorde was retired in 2003 due to high costs, environmental concerns, and operational challenges, Lingkong Tianxing aims to overcome these hurdles with advanced materials, quieter engines, and a more sustainable operational model.
A New Era of High-Speed Travel
This announcement underscores the growing competitiveness of China’s private aerospace sector, which has already demonstrated expertise in building rockets, satellites, and drones. Now, with its eyes set on high-speed suborbital travel, the sector is poised to transform the way people think about intercontinental flights.
“Just imagine making an intercontinental flight within just two to three hours that you would now spend 10 hours or longer on,” Deng said, emphasizing the transformative potential of supersonic travel.
Globally, the race to develop next-generation supersonic aircraft is intensifying, with companies in the United States and Europe also working on similar projects. If Lingkong Tianxing’s timeline holds, China could become a leading player in the revival of ultrafast commercial airliners.
The maiden flight of Cuantianhou in 2026 will mark a pivotal moment in this ambitious endeavor, setting the stage for a new era of supersonic transportation.
