Doesn't Go Boom

Concorde flew from London to New York in three and a half hours. It soared at nearly twice the speed of sound, leaving an almighty sonic boom in its wake. The noise restricted where it could fly, but now NASA hopes it can resurrect faster-than-sound travel, with quiet supersonic flight.

Enter X-59 QueSST (Quiet SuperSonic Technology), developed by NASA and Lockheed Martin. With its uniquely designed shape, the aircraft should allow NASA to break the sound barrier again – but this time, with no more noise than your neighbour slamming a car door.

At Lockheed Martin’s Skunk Works factory in Palmdale, California, an engineer works on the fuselage section of the X-59. The black rectangular panels are air intakes for the plane’s environmental control system (ECS), and the silver grate is the ECS exhaust.

Usually, the engine is placed on the bottom of an aircraft, but on the X-59, this section of the inlet and engine are mounted to the top of the plane. This is so the shock waves from the inlet and engine are shielded by the wing to reduce the sonic boom to a sonic thump © Lockheed Martin
