NASA's X-59 Achieves Supersonic Speed and Altitude Milestones
NASA's X-59 experimental aircraft successfully completed a test flight reaching Mach 1.4 at 55,000 feet, demonstrating its ability to achieve necessary supersonic conditions. This marks a critical step towards the Quesst mission, aiming to test quiet supersonic flight over populated areas and gather public feedback on the resulting "sonic thump."
Key points
- NASA's X-59 research aircraft achieved Mach 1.4 (approximately 924 mph) and an altitude of 55,000 feet in a recent test flight.
- These speed and altitude figures are critical conditions for the X-59's planned supersonic flights over U.S. communities.
- The aircraft is designed to produce a "quiet sonic thump" instead of a traditional loud sonic boom.
- The Quesst mission, scheduled for later this year, will involve flying the X-59 over populated areas to collect public reactions to its noise signature.
- Before community flights, NASA will conduct an acoustic validation phase to measure the aircraft's supersonic sound signature.
NASA's experimental X-59 aircraft has achieved crucial speed and altitude milestones in recent test flights, bringing it closer to its goal of demonstrating quiet supersonic flight. In its latest demonstration, the X-59 reached Mach 1.4 (around 924 mph) and an altitude of 55,000 feet.
This flight represents a significant step in validating the aircraft's capabilities for future missions. Earlier in June, the X-59 had already flown at Mach 1.1. The X-59 is engineered to fly faster than the speed of sound while producing a subdued "sonic thump" rather than the disruptive boom typically associated with supersonic jets.
The next phase involves the Quesst mission, which is planned for later in the year. During this mission, the X-59 will fly over U.S. communities to allow NASA to gauge public perception of the aircraft's noise. Prior to these community flights, an acoustic validation phase will precisely measure the supersonic sound signature to confirm its reduced noise level.
