Mach-3 Supersonic Passenger Aircraft is Coming; Travel Three times Faster than Sound

Mach-3 Supersonic Passenger Aircraft
Aerospace tourism company Virgin Galactic and Rolls-Royce are set to build a Mach-3 supersonic aircraft that will travel three times faster than sound. The Mach number is used to indicate the speed of the aircraft.

The new Mach-3 supersonic aircraft will fly faster than the Concorde that flew on the Mach-2 from 1976 to 2003. With a triangular 'Delta Wings' carrying 9 to 19 passengers, the aircraft is designed to fly at an altitude of 60,000 feet (18,000 meters, twice as high as a normal plane). 

The aircraft will be able to take off and land at existing airports. At the same time, fuel efficiency and noise are the biggest challenges facing these aircraft. Concerns about thermal management, maintenance, noise, pollution and financial liability are being carefully analyzed, Virgin Galactic officials said.

Virgin Galactic unveiled the design concept after gaining authorization from the US Federal Aviation Administration's Center for Emerging Concepts and Innovation to develop a certification framework for a new generation of supersonic passenger travel.

"The design philosophy of the aircraft is geared around making high speed travel practical, sustainable, safe and reliable while making customer experience a top priority," said the brand.

"The aircraft would take off and land like any other passenger aircraft and be expected to integrate into existing airport infrastructure and international airspace around the world."

NASA is preparing to develop the X-59, a noiseless supersonic test aircraft. The prototype was made by Lockheed Martin in California.
