Here you see the X-59 scaled model inside the JAXA supersonic wind tunnel during critical tests related to sound predictions.

NASA Administrator Bridenstine stands with AFRC center director McBride by model NASA's Supersonic X-Plane, X-59 Quiet Supersonic Technology or QueSST. Bridenstine spoke at press event at Mojave Air and Space Port in California. The goal of X-59 is to quiet the sound when aircraft pierce the speed of sound and make a loud sonic boom on the ground.

An aerospace research engineer and technicians inspect the X-59 Commercial Supersonic Transport model’s installation and alignment before testing. The blade hanging from the top of the tunnel will be measuring the shock waves coming from the model during testing. The intent is to develop a supersonic aircraft with less sonic boom.

A Lockheed Martin technician looks at the connector installation on the cad model of the X-59 airplane. The aircraft, under construction at Lockheed Martin Skunk Works in Palmdale, California, will demonstrate the ability to fly supersonic while reducing the loud sonic boom to a quiet sonic thump.

The X-59 Commercial Supersonic Transport model is installed upside down in the test section of the GRC 8x6 Supersonic wind tunnel. The blade hanging from the top of the tunnel will be measuring the shock waves coming from the bottom of the model during testing. The shock waves coming from the bottom of the model represent the sonic boom reaching the ground during flight. The shape of the model is designed so as to greatly reduce the shock waves to prevent the typical boom coming from a supersonic aircraft.
