Lockheed Martin and NASA begin building 'son of Concorde' X-59 plane that could see the return of supersonic passenger travel

 

The supersonic plane is officially known as the X-59 Quiet Supersonic Technology aircraft

The 'Son of Concorde' will cut flight times in half without producing sonic boom, NASA hopes

The X-59 is designed to cruise at 55,000 ft at a speed of 940 mph, with the first flight scheduled for 2021

NASA says it will create a sound 'about as loud as a car door closing'  

콩코드의 후예가 태어난다 일명 "콩코드의 아들 X59" 제작 착수   록히드 마틴과 나사가 초음속 여객기 일명 "콩코드의 아들 X59"가 제작에 들어갔다. 록히드 마틴은 공식적으로 X-59 Quiet Supersonic Technology 항공기로 알려진 이 초음속 비행기를 초음속으로 이동할 때 발생하는 조용한 소닉 붐(음속 폭음)을 완벽하게 실현하기 위해 나사와 함께 제작에 돌입했다. X-59가 소닉 붐을 일으키지 않고 비행시간을 반으로 단축시킬 것이라고 NASA는 기대하고 있다. 시속 1,504km의 속도로 16,500m 고도를 비행하도록 설계되었으며, 첫 비행은 2021년으로 예정되어 있다. NASA는 '차 문이 닫히는 것만큼 만한' 소리를 낼 것이라고 말한다. 영국과 프랑스가 최초로 개발한 초음속 여객기 콩코드는 1976년 첫 취항 이래 2003년 까지 운행되었지만 소음과 경제성 문제가 대두되어 역사의 뒤안길로 사라지고 말았다. 황기철 콘페이퍼 에디터 큐레이터 Ki Cheol Hwang, conpaper editor, curator

Lockheed Martin has begun building a 'son of Concorde' plane that could herald the return of supersonic passenger travel.

Officially known as the X-59 Quiet Supersonic Technology aircraft, it is being built with NASA to perfect quiet sonic booms that would allow craft to go supersonic over land. The X-59 will conduct its first flight in 2021. It is designed to cruise at 55,000 feet at a speed of about 940 mph and create a sound about as loud as a car door closing, 75 Perceived Level decibel (PLdB), instead of a sonic boom.

Lockheed Martin said the move 'marks a milestone to bring supersonic commercial travel over land one step closer to reality.'
