Travel Around the World in One Hour on Mach 9
The Texas aerospace company has just unveiled its Stargazer hypersonic aircraft concept that would take passengers more than 50 kilometers high. With a cruising speed of Mach 9, the manufacturer claims it could reach anywhere on earth in an hour.
Will the future of commercial aviation be hypersonic?
At least that’s what Venus Aerospace, a Texas company that has just unveiled its Stargazer hypersonic spaceplane, is hoping for. According to the manufacturer, the device will be able to reach the speed of Mach 9 and transport passengers anywhere in the world in an hour. To reach such a speed, the plane will fly at a very high altitude, nearly 52 kilometers (170,000 feet). . Stargazer will use conventional airports and will therefore need to fly at subsonic speeds for takeoff and landing.
Once at altitude it accelerates to Mach 9. The aircraft will be 45 meters long with a wingspan of 30 meters and will be able to carry up to 12 people. A zero carbon footprintMach 9 means nine times the speed of sound, which varies with temperature and therefore altitude.
The team worked with NASA to ensure that the sonic boom generated at this altitude would not be audible from the ground. Venus Aerospace hasn’t said what the Stargazer will use for fuel, but says the carbon footprint will be zero. However, the device is still in the concept phase and the company does not give a deadline for a possible prototype.
In addition, since the circumference of the earth is approximately 40,075 kilometers, it would take at least 20,000 km/h to reach any point on earth, a minimum speed that increases for an airplane flying at altitude. That question doesn’t seem to worry investors, however, as Venus Aerospace has managed to raise more than $33 million in funding.
