China unveils Cuantianhou hypersonic drone

 

The Cuantianhou hypersonic drone

China has unveiled the Cuantianhou hypersonic drone with unique engines.

Sichuan Lingkong Tianxing Technology accelerated the development of the Cuantianhou hypersonic drone. Tests of the device with detonation engines will begin in 2026, and its speed will exceed Mach 4.

The Chinese company Sichuan Lingkong Tianxing Technology presented a model of the Cuantianhou hypersonic drone in Chengdu. Weighing 1.5 tons and 7 meters long, the device is equipped with two Jindou-400S detonation engines, which will allow it to accelerate to a speed of 4.2 Mach.

The first tests of Cuantianhou were planned for 2027, but successful prototype tests allowed them to be postponed to 2026. The company has conducted 88 tests over six years, including autumn engine launches on simple models.

Two Jindou-400S detonation engines will be installed on the drone. They are lighter and more efficient than the previous version of the Jindou-400. The new engine weighs 100 kg, has a length of 1.9 m and develops a thrust of 4 kN, consuming only 6 kg of fuel per 50 km flight at a speed of Mach 4.

The principle of operation of the engine is based on explosive detonation of fuel, which creates a more powerful jet stream compared to conventional combustion.

The developers believe that hypersonic civil aviation is already close to reality. Sichuan Lingkong Tianxing Technology plans to take the Da Sheng hypersonic passenger aircraft into the air in 2030.

Cuantianhou resembles the American SR-71 Blackbird reconnaissance aircraft, but surpasses it in speed and altitude. The SR-71 reached Mach 3.32, and the Chinese drone will accelerate to Mach 4.2 at an altitude of 20 km.

Chinese engineers are confident that their developments are ahead of their competitors. For example, the American Hermeus plans to create a hypersonic aircraft with a speed of Mach 5, but the project is three years behind schedule. Swiss startup Destinus is working on hydrogen-fueled airplanes, but their technology is still far from commercial implementation.
