PALMDALE, Calif., Nov. 12,
2024 /PRNewswire/ -- Lockheed Martin Skunk
Works® (NYSE: LMT), in partnership with NASA
Aeronautics, started X-59 engine run testing, marking the
aircraft's final major system check-out before taxi tests and first
flight. The tests also mark the first time the X-59 was powered
fully internally.
During the tests, Lockheed Martin is verifying inlet and nozzle
performance, aircraft and engine structural and system interfaces,
and engine control algorithms. Previously, the X-59 had been
powered externally – electrically, hydraulically and
pneumatically.
"It was an emotional high to see and hear another innovative,
boundary-pushing Skunk Works X-plane come to life," said
Pat LeBeau, X-59 program manager,
Lockheed Martin Skunk Works. "The team has done an incredible job,
and we remain focused on the path forward to a safe and successful
first flight."
Engine runs are the last, critical system check-out prior to
first flight that verifies proper functionality of the X-59 as an
integrated system operating on its own power. The tests ensure the
engine can be controlled through the vehicle management system and
engine computer. They also verify management of the fuel system,
vibration and temperature interactions and more.
Following these successful engine runs, the X-59 will be
evaluated for electromagnetic interference effects, simulated
in-flight failure modes and validation of the emergency power
system. Once those are complete, the aircraft will undergo
low-speed and high-speed taxi tests in preparation for first
flight.
The X-59 is a one-of-a-kind test aircraft designed to achieve
quiet supersonic flight and transform future commercial air travel.
It is a singularly unique, national asset. Lockheed Martin and NASA
are taking every precaution in a paced, systematic and disciplined
approach to ensure safety and success of the mission.
