America Creates a 770-Mile Corridor for Testing Supersonic Aircraft Up to Mach 3

America's Federal Aviation Agency signed an agreement with the state of Kansas's department of transportation to establish a 770-nautical mile Kansas Supersonic Transportation Corridor for testing aircraft up to Mach 3, reports Aviation International News:The agreement would provide a critical testing site for the emerging group of supersonic aircraft as civil supersonic flight remains banned over land. Flight testing for models such as Aerion's AS2 and Boom's Overture is expected this decade, while NASA noise trials with the Lockheed Martin X-59 demonstrator are anticipated by 2024. "This year marks 73 years since Chuck Yeager broke the sound barrier, and with this supersonic flight corridor Kansas will have a unique role in the next generation of supersonic transportation," said Sen. Jerry Moran (R-Kansas) in the announcement of the agreement... The General Aviation Manufacturers Association (GAMA) lauded the establishment of the corridor, saying it will help in the "re-birth" of civil supersonic travel. "The Kansas Supersonic Transportation Corridor will assist in the assessment of sound mitigating structural and engine designs as well as state of the art atmospheric acoustic modeling that eliminates the sonic boom and shapes the noise signature of an aircraft traveling faster than the speed of sound to a very low volume rumble," said GAMA president and CEO Pete Bunce. "The validation of these technological breakthroughs through the use of sophisticated ground acoustic and telemetry sensors will provide the necessary data to assist global regulators and policymakers in modernizing supersonic flight policies." NASA plans to use the Lockheed Martin X-59 demonstrator to test low-boom noise effects over various populations. "I'm really excited about quiet supersonic technology and its ability to be transformative for flight and our economy," said NASA Administrator Jim Bridenstine. Aerion, meanwhile, plans to test "Boom Cruise" technology that is designed to keep the sonic boom from reaching the ground with plans to begin flight trials in 2025, while Boom is looking at low boom technologies for its commercial airliner Overture.
