NASA has successfully completed a ground test of the maximum afterburner engine run on its X-59 quiet supersonic research aircraft. The test, conducted at Lockheed Martin’s Skunk Works facility in California, marks an important milestone in the project’s progress toward flight.
The F414-GE-100 engine with afterburner is crucial for achieving supersonic speed requirements. The ground test demonstrated the engine’s ability to operate within safe temperature limits and sufficient airflow, as well as its synchronization with other aircraft systems.
As part of NASA’s Quiet Supersonic Technology (QUST) mission, the X-59 aims to reduce sonic booms to make supersonic flight over land more feasible. The aircraft is expected to take its first flight in 2025, paving the way for quieter supersonic travel.
