China is advancing its supersonic aviation technology through several key companies and projects. Sichuan Lingkong Tianxing Technology Co., a company based in Chengdu, has unveiled the Yunxing family of supersonic aircraft, including the Cuantianhou ("Soaring Monkey") prototype, designed to fly at Mach 4, twice the speed of the retired Concorde. This aircraft is intended for commercial use, with plans for its first test flight in 2026 to evaluate aerodynamics, heat-resistant materials, and power systems.  The company aims to conduct the maiden flight of its full-sized supersonic passenger jet, named Dasheng or Monkey King, by 2030.  The aircraft is designed to operate in near-space, between 20-100 kilometers above Earth, and could potentially transport passengers from Beijing to New York in about two hours.

The development of the Yunxing aircraft incorporates advanced technologies, including lightweight, high-strength composite materials capable of withstanding surface temperatures exceeding 1,000 degrees Celsius during high-speed flight.  The aircraft's design, which features a high lift-to-drag ratio and a unique launch and landing sequence involving a booster and vertical landing, draws inspiration from the concept of a stone skimming across water, a principle associated with hypersonic flight.  The company has already successfully tested the prototype, validating its aerodynamics, thermal protection, and control systems.

Another significant player in China's aerospace sector is Xi'an Supersonic Aviation Technology Co., Ltd. (SAT), headquartered in Xi'an. SAT specializes in high-quality UAV systems, unmanned vehicles/robots, and complex aerospace engine components for large carrier rockets, aero engines, weapon engines, and gas turbines.  The company leverages proprietary technologies such as vacuum brazing, powder metallurgy, and industrial 3D printing to produce customized parts and systems.

 SAT serves both domestic and international markets, with a significant presence in Europe, the Middle East, Africa, and Asia.  The company's products are used in various fields, including scientific research, space exploration, aviation, power generation, and national defense.

Additionally, Comac, China's state-owned aircraft manufacturer, is developing the C949 supersonic jet, which aims to offer a 50% increase in range and a 95% reduction in noise compared to the Concorde. This project, detailed in a recent academic paper, focuses on reducing sonic booms to a level comparable to a hairdryer, potentially overcoming regulatory barriers that previously prevented overland supersonic flights.  These advancements highlight China's growing ambition and capability in the field of supersonic aviation, with both commercial and military applications in development.
