![]() īy October, NASA Langley had completed three weeks of wind tunnel testing of an 8%- scale model, with high AOAs up to 50° and 88° at very low speed, up from 13° in previous tunnel campaigns. On June 26, 2018, the US Air Force informed NASA it had assigned the X-59 QueSST designation to the demonstrator. On April 2, 2018, NASA awarded Lockheed Martin a $247.5 million contract to design, build and deliver in late 2021 the Low-Boom X-plane. ![]() ![]() While NASA received three inquiries for its August 2017 request for proposals, Lockheed was the sole bidder. The preliminary design review was to be completed by June 2017. Ī 9% scale model was to be wind tunnel tested from Mach 0.3 to Mach 1.6 between February and April 2017. In February 2016, Lockheed Martin was awarded a preliminary design contract, aiming to fly in the 2020 timeframe. It is expected to cruise at Mach 1.42 (1,510 km/h 937 mph) at an altitude of 55,000 ft (16,800 m), creating a low 75 Perceived Level decibel (PLdB) thump to evaluate supersonic transport acceptability.ĭevelopment A model in a wind tunnel at NASA Langley, September 2017 Preliminary design started in February 2016, with the X-59 to be delivered to NASA in 2021 for flight testing in 2023. ![]() The Lockheed Martin X-59 QuessT ("Quiet SuperSonic Technology") is an American experimental supersonic aircraft being developed at Skunk Works for NASA's Low- Boom Flight Demonstrator project. ![]()
