Areas of interest for the test were sea level takeoff and landing at Mach 0.2, subsonic cruise at Mach 0.9, and supersonic cruise at Mach 1.4. Knowing the aircraft's speed and attitude is critical for flight safety and is also critical data for the Sonic Boom mission. The probe will be the primary instrument for the flight test of the X-59 for determining angle of attack, angle of sideslip, airspeed, and pressure altitude of the aircraft in flight. A backup nose probe was also run through the same test matrix as the primary probe. About 725 high quality data runs were recorded during testing to be used in the calibration of the probe. Most data were collected using continuous roll angle sweeps at a set Mach number and pitch angle. The probe was successfully tested and calibrated at 19 Mach numbers between Mach 0.25 and Mach 1.7. Two wind tunnel tests were conducted in the NASA Glenn Research Center (GRC) 8- by 6-Foot Supersonic Wind Tunnel to calibrate the nose probe for the X-59. and international regulators to potentially allow supersonic flight over land, drastically reducing travel time within the U.S. The data from the X-59 test flights will be provided to U.S. The plane will be used to collect human response data over select U.S. X-59 Air Data Probe Calibration Wind Tunnel Test NASA's aeronautical innovators are working with Lockheed Martin to design and build a supersonic X-plane, the X-59, under the the Low Boom Flight Demonstrator (LBFD) Project, that produces a gentle thump rather than a loud sonic boom.
