Quick Takeaways
-
NASA and JAXA successfully tested a scaled model of the X-59 aircraft in a wind tunnel to assess noise levels under supersonic flight conditions.
-
The X-59 is engineered to produce a quieter sonic thump instead of a loud sonic boom, leveraging a unique design to prevent shock waves from merging.
-
This testing, part of NASA’s Quesst mission, aims to gather data on acceptable sound levels for future quiet supersonic travel and involves critical comparisons with Computational Fluid Dynamics predictions.
- The X-59, built by Lockheed Martin, is nearing its first flight later this year, ultimately contributing to the development of technologies for faster, quieter commercial air travel.
X-59 Model Tested in Japanese Supersonic Wind Tunnel
Researchers from NASA and the Japanese Aerospace Exploration Agency (JAXA) recently conducted tests on a scale model of the X-59 experimental aircraft in a wind tunnel in Chofu, Japan. This test aimed to assess the noise levels produced beneath the aircraft during flight.
The X-59 is designed to travel faster than sound while minimizing the disruptive sonic boom. Therefore, understanding the aircraft’s noise profile is essential for its future operations over populated areas.
The X-59 measures 99.7 feet long with a wingspan of 29.7 feet. In contrast, the JAXA wind tunnel is relatively small, measuring just over 3 feet long and wide. To fit this setting, researchers used a model scaled to 1.62% of the actual aircraft—about 19 inches from nose to tail.
During the tests, they simulated conditions at Mach 1.4, which equals approximately 925 miles per hour. As a result, the tests provided vital data to validate predictions made through Computational Fluid Dynamics modeling. This modeling predicts how air will flow around the aircraft.
This round of tests marked the third set conducted for the X-59 model. Previous tests occurred at JAXA and NASA’s Glenn Research Center in Ohio. Collectively, the data gathered will help scientists understand the shock waves generated by the X-59 at supersonic speeds.
Traditional supersonic jets create loud sonic booms due to merging shock waves. However, the X-59’s innovative design aims to avoid this merging, producing a quieter sonic thump instead.
Manufactured in Palmdale, California, by Lockheed Martin Skunk Works, the X-59 is now preparing for its historic first flight later this year. NASA’s Quesst mission supports the advancement of quiet supersonic travel. This mission will allow researchers to gather public opinions on acceptable noise levels during such flights.
Through the development of the X-59, NASA seeks to provide the necessary design tools and technologies for future quiet supersonic airliners. These innovations could enable commercial operators to achieve high speeds without disturbing communities on the ground.
