NASA's X-59 supersonic aircraft inches closer to historic first flight with key tests underway

NASA's X-59 aircraft is moving closer to its historic first flight, with a series of crucial tests and inspections now underway. Designed to fly faster than the speed of sound without generating a disruptive sonic boom, the X-59 aims to revolutionize supersonic travel, potentially paving the way for commercial flights over land.

NASA said the experimental plane X-59 is currently undergoing a rigorous testing phase to ensure its unique design performs. This phase includes important structural tests and evaluations of the aircraft’s fuselage, wings, and control surfaces. Engineers are focused on predicting and validating how these components will interact during flight, using extensive ground testing to refine their models.

According to NASA, the engineering team since 2022 has gathered valuable data on the X-59's structural integrity, and tests have assessed the aircraft's response to various forces and vibrations. "You do these tests, you get the data, and things compare well in some areas and in other areas you want to improve them," said Walt Silva, Senior Research Scientist at NASA Langley Research Center in Hampton, Virginia, who serves as structures lead for the X-59. "The testing not only tells us how structurally sound the aircraft is, but also what kind of forces it can take once it is in the air. So, you figure that all out and then you work towards making it better."

The American space agency said this year, the X-59 successfully completed its final trio of critical structural tests. These included structural coupling tests where computer-controlled movements tested the aircraft’s control surfaces, vibration response tests using "shakers" and a proof test to ensure the aircraft can handle flight forces. Additionally, the agency said the ejection seat was installed and passed inspection, enhancing pilot safety.
