NASA\u2019s quiet supersonic X-59 research aircraft has cleared electromagnetic testing, confirming its systems will work together safely, without interference across a range of scenarios.<\/p>

\u201cReaching this phase shows that the aircraft integration is advancing,\u201d said Yohan Lin, NASA\u2019s X-59 avionics lead. \u201cIt\u2019s exciting to see the progress, knowing we\u2019ve cleared a major hurdle that moves us closer to X-59\u2019s first flight.\u201d<\/p>

Electromagnetic interference occurs when an electric or magnetic field source affects an aircraft\u2019s operations, potentially impacting safety. This interference, whether from an external source or the aircraft\u2019s own equipment, can disrupt the electronic signals that control critical systems \u2013 similar to effects that lead to static or crackling on a radio from a nearby emitting device, like a phone.<\/p>

The tests, conducted at contractor Lockheed Martin Skunk Works\u2019 facility in Palmdale, California, ensured that the X-59\u2019s onboard systems \u2013 such as radios, navigation equipment, and sensors \u2013 did not interfere with one another or cause unexpected problems. During these tests, engineers activated each system on the aircraft one at a time while they monitored the other systems for possible interference.<\/p>

NASA\u2019s X-59 quiet supersonic research aircraft successfully completed electromagnetic interference (EMI) testing at Lockheed Martin Skunk Works in Palmdale, California. During EMI tests, the team examined each of the X-59\u2019s internal electronic systems, ensuring they worked with one another without interference. The X-59 is designed to fly faster than the speed of sound while reducing the loud sonic boom to a quieter sonic thump.<\/div>

\u201cThis testing helped us determine whether the systems within the X-59 are interfering with each other,\u201d Lin said. \u201cIt\u2019s called a source-victim test \u2013 essentially, we activate one system and monitor the other for issues like noise, glitches, faults, or errors.\u201d<\/p>

The X-59 will generate a quieter thump rather than a loud boom while flying faster than the speed of sound. The aircraft is the centerpiece of NASA\u2019s\u00a0Quesst<\/a>\u00a0mission, which will provide regulators with information that could help lift current bans on commercial supersonic flight over land. Currently, the aircraft is progressing through ground tests to ensure safety and performance. These included the recent,\u00a0successful completion<\/a>\u00a0of a set of engine tests. The electromagnetic interference testing to examine the X-59\u2019s internal electronic systems followed.<\/p>

Other electromagnetic interference testing involved the team looking at the operation of the X-59\u2019s landing gear, ensuring this critical component can extend and retract without affecting other systems. And they tested that the fuel switch shutoff was functioning properly without interference.<\/p>

Electromagnetic compatibility was also assessed during this testing \u2013 making sure the X-59\u2019s systems will function properly when it eventually flies near NASA research aircraft.<\/p>

The EMI testing ensures an aircraft\u2019s systems function properly under various conditions of electromagnetic radiation. The X-59 is the centerpiece of the NASA\u2019s Quesst mission, designed to demonstrate quiet supersonic technology and provide data to address a key barrier to commercial supersonic travel.<\/div>

Researchers staged the X-59 on the ground in front of NASA\u2019s F-15D, placing them 47 feet apart, then 500 feet apart. The proximity of the two aircraft replicated conditions needed for the F-15D to use a special probe to gather measurements\u00a0about the shock waves<\/a>\u00a0the X-59 will produce.<\/p>

\u201cWe want to confirm there\u2019s compatibility between the two aircraft, even at close proximity,\u201d Lin said.<\/p>

For the electromagnetic compatibility testing, the team powered up the X-59\u2019s engine while turning on the F-15D\u2019s radar, C-band radar transponder, and radios. Data from the X-59 were transmitted to NASA\u2019s Mobile Operations Facility, where control room staff and engineers monitored for anomalies.<\/p>

\u201cYou want to make discoveries of any potential electromagnetic interference or electromagnetic compatibility issues on the ground first,\u201d Lin said. \u201cThis reduces risk and ensures we\u2019re not learning about problems in the air.\u201d<\/p>

Now that electromagnetic testing is complete, the X-59 is ready to move on to aluminum bird tests \u2013 during which data will be fed to the aircraft on the ground under both normal and failure conditions \u2013 and then taxi tests before flight.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
