NASA Picks Lockheed Martin to Make Low-Boom Supersonic X-Plane
NASA just announced the next step in supersonic flight research: a new piloted X-plane to be built by Lockheed Martin called the Low-Boom-Flight Demonstrator (LBFD). The aircraft, about the size of an F-16, will take advantage of a long and slender shape to decrease the noise of a sonic-boom.
First flight of the LBFD is slated for summer of 2021. Shortly thereafter, NASA plans to fly the plane up to Mach 1.4 at an altitude of 55,000 feet over 50-square-mile testing areas in the American Southwest. Because the point of the program is to build a supersonic plane with a quieter sonic-boom, NASA will survey hundreds of people living in the communities under the flight testing areas to find out if they heard-booms coming from the LBFD and gauge their reactions to the noise.
