Yohan Lin, NASA’s X-59 avionics lead, described the achievement as a “major hurdle” that brings the aircraft closer to its first flight. The testing was conducted at Lockheed Martin Skunk Works in Palmdale, California, where engineers assessed whether the aircraft’s onboard systems, such as radios, navigation equipment, and sensors, interfered with one another.
Electromagnetic interference occurs when electrical or magnetic fields disrupt critical systems, potentially affecting aircraft operations. Engineers carried out a “source-victim” test, activating each system individually and monitoring for malfunctions such as noise, glitches, or errors.
The X-59, a core component of NASA’s Quesst mission, is designed to reduce the noise of supersonic flight by producing a quieter sonic “thump” instead of a loud boom. The project aims to provide data that could help lift current restrictions on commercial supersonic flight over land.
Recent tests also evaluated the aircraft’s landing gear operation and fuel shutoff systems to ensure they function correctly without interference. Engineers further examined electromagnetic compatibility by positioning the X-59 near NASA’s F-15D research aircraft, simulating conditions required for future airborne shock wave measurements.
During the compatibility tests, the X-59’s engine was powered up, while the F-15D activated its radar and communication systems. NASA engineers monitored the results from a mobile operations facility, ensuring there were no unexpected anomalies.
Lin emphasised that testing on the ground is crucial for identifying potential electromagnetic interference before flight. Detecting and resolving any issues in advance reduces risk and improves overall flight safety.
With electromagnetic testing complete, the X-59 will now move on to aluminium bird tests, where engineers simulate various operational conditions on the ground. This will be followed by taxi tests before the aircraft takes to the skies for the first time.
