CTOnews.com, May 2 (Xinhua) Texas-based Venus Airlines is developing a hypersonic (Hypersonic) aircraft called the stargazer, which can fly at the edge of the atmosphere at nine times the speed of sound (CTOnews.com Note: Mach 9, about 11104 kilometers per hour), reducing the flight time of any two cities in the world to less than an hour.

Hypersonic (Hypersonic) is defined as five times the speed of sound, and the last commercial supersonic jet Concorde had a speed of Mach 2, or about 2470 km / h. The fastest plane ever, Lockheed's SR-71 Blackbird, flew at a speed of 3.2mach (about 3950 km / h).

Stargazer is a business jet that can carry 12 passengers and is 150 feet long, 100 feet wide and weighs 68,000 kilograms. It will use a rotating detonation engine at 20000 revolutions per second and will ignite the rocket at a supersonic speed after takeoff at an altitude of 170000 feet. The rotary detonation engine is a new type of propulsion technology that can continuously generate supersonic explosions inside the engine, saving 20% more fuel than traditional engines, and the U.S. Navy is also promoting this technology.

Andrew Dugby, co-founder and chief technology officer of rotary detonation engine Venus Airlines, said they had successfully tested a prototype engine at Spaceport headquarters in Houston, using propellant stored at room temperature. This is the first time that this propellant has been used to test a rotary detonation engine, which is a key step for the realization of a real flight system.

Venus Airlines, founded in 2020, has raised $33 million to build a stargazer. The company plans to first test hypersonic flight with a 20-foot-long drone, with the goal of achieving five times the speed of sound. A prototype of the stargazer will be built after that, but the exact date has not yet been announced.

In addition to Venus Airlines, other companies are also competing to develop hypersonic aircraft. Syrah Space is building a plane called the Dream Chaser, and Hermius in Atlanta is developing an aircraft that can reach five times the speed of sound, called the Quarterhorse.
