X-59: New steps towards silent supersonic flight
Specialists from NASA and the Japan Aerospace Exploration Agency (JAXA) have successfully concluded key tests of a scaled model of the experimental X-59 aircraft. The tests were conducted in JAXA's supersonic wind tunnel in Chofu. The primary objective of these trials was to measure the noise level generated by the aircraft, which is critically important for assessing its impact on people on the ground.
The X-59 is designed for supersonic flight without a loud sonic boom. For the tests, a model scaled to 1.62% of the original was subjected to airflow simulating a design speed of Mach 1.4 (approximately 1488 km/h). This enabled the collection of data on air behavior and the noise generated by shockwaves, which will subsequently be compared with numerical simulations. The X-59's unique design prevents a loud sonic boom; instead, a significantly quieter "thump" is anticipated.
The X-59 aircraft is currently undergoing final ground tests in Palmdale, California, prior to its historic maiden flight, which is scheduled for this year. The success of this project will facilitate the development of new design tools and technologies for future passenger supersonic airliners capable of flying rapidly without causing discomfort to residents on the ground.
