Blue Ridge Research and Consulting LLC of Asheville, North Carolina EMS Brüel & Kjær Inc. of Folsom, California NASA is designing and building the X-59 research aircraft – a piloted, single-seat supersonic X-plane – with technology that reduces the loudness of a sonic boom to that of a gentle thump. NASA’s aeronautical innovators are leading a team across government and industry to collect data that could allow supersonic flight over land, dramatically reducing travel time within the United States or to anywhere in the world. The scope of the work under this contract includes supporting NASA in the planning, execution, and documentation of phase three of the agency’s Low-Boom Flight Demonstration mission.
