NASA X-Plane Looks To The Future Of Quiet Supersonic Planes


For the first time in decades, NASA aeronautics is moving forward with the construction of a piloted X-plane, designed from scratch to fly faster than sound with the latest in quiet supersonic technologies,by reducing the disruptive sonic boom sound associated with supersonic flight.

The proposed aircraft will measure 28.65 meters long, have a wingspan of about 9 meters , and have a takeoff weight of 14,650 kg.Based on the company’s design, the X-plane will be powered by a single General Electric F414 engine, the same used by F/A-18E/F fighters.

It will be flown by a single pilot and have a top speed of Mach 1.5 (1590 km; 990 mph) and a speed of Mach 1.42 (1513 km; 940 mph) at a cruising altitude of 16764 meters.


NASA expects the new aircraft to create a sound of less than half the noise level — or more akin to the sound of a closing car door.

This new contract is a separate venture from Lockheed Martin’s work with Aerion Corp. to develop a supersonic business jet, the AS2, which has its first flight planned for 2023.
