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:

據《航空國際新聞》報道，美國聯邦航空局與堪薩斯州交通部簽署了一項協議，他們將在堪薩斯建立一條770英里的超音速運輸走廊，用於測試新飛機:

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…

該協議將為新興的超音速飛機集團提供一個關鍵的測試場地，因為民用超音速飛行目前仍被禁止在陸地上空飛行（只能海上）。Aerion公司的AS2和Boom公司的Overture等模型的飛行測試，預計將在10年內進行測試，而NASA與洛克希德·馬丁公司的X-59演示機的噪音測試，預計將在2024年進行。

“今年是 Chuck Yeager 突破音障的73週年，有了這條超音速飛行走廊，堪薩斯州將在下一個時代的超音速運輸中扮演一個特殊的重要角色。”州參議員傑瑞·莫蘭在協議的聲明中説了這些話……

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.”

通用航空製造商協會(GAMA)對走廊的建立表示讚賞，稱這將有助於民用超音速旅行的“重生”。

伽馬總裁兼首席執行官皮特説：“堪薩斯超音速運輸走廊還將用來協助評估減聲結構和引擎設計，以及最先進的大氣聲學建模，並記錄飛行速度高於音速的飛機的噪聲特徵，尋求方法解決音爆帶來的轟隆噪音。”

“通過使用先進的地面聲學和遙測傳感器，這些數據將給未來技術突破提供必要的驗證，用來協助全球監管機構和決策者建立超音速飛行的現代化政策。”

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.

NASA計劃使用洛克希德·馬丁公司的X-59演示機，來測試對不同人羣的低爆噪聲效果（簡單説：讓新的超音速飛機從人羣上空飛過，看看有什麼特殊影響）。美國宇航局局長吉姆表示:“我對‘靜音’超音速技術，及其未來改變超音速飛行領域，和經濟方面的影響感到非常期待。”

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.

與此同時，Aerion計劃測試“爆轟巡航”(Boom Cruise)技術，該技術主要是想辦法阻止音爆傳到地面，他們計劃在2025年開始飛行試驗，而Boom公司還在他們的商業客機領域研究低爆轟技術。
