The tests also mark the first time the X-59 was powered fully internally. </p><p>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.</p><p>"It was an emotional high to see and hear another innovative, boundary-pushing Skunk Works X-plane come to life," says 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."</p><p>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.</p><p>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.</p><p>The X-59 is a one-of-a-kind test aircraft designed to achieve quiet supersonic flight and transform future commercial air travel. Lockheed Martin and NASA are taking every precaution in a paced, systematic and disciplined approach to ensure safety and success of the mission.</p>  <div class="addthis_inline_share_toolbox"></div> </div> <div class="separator-sm"></div> <table class="main-table no-border"> <tr> <td colspan="2"><b>Contact details from our directory:</b></td> </tr> <tr> <td class="first-column"><a href="direct_detail.html?company=131011" title="Lockheed Martin Skunk Works">Lockheed Martin Skunk Works</a></td> <td>Airborne Communication Systems, Airframer, Collision Avoidance Systems/TCAS, Design Services, Research/Consulting Services, Technical/Eng/Scientific Studies</td> </tr> <tr class="no-border"> <td class="first-column"><a href="direct_detail.html?company=115400" title="NASA Langley Research Center">NASA Langley Research Center</a></td> <td>Research/Consulting Services, Testing Services, Wind Tunnels</td> </tr> </table> <div class="separator-sm"></div> <table class="main-table no-border"> <tr> <td><b>Related aircraft programs:</b></td> </tr> <tr class="no-border"> <td class="first-column"><a href="aircraft_detail.html?model=X_59">Lockheed Martin Skunk Works X-59 QueSST</a></td> </tr> </table> </div> </div> </div> <div class="col-lg-4"> <div class="separator-sm d-block d-md-none"></div> <div class="stickify text-center text-md-right"> <div class="blackout"></div> <div class="d-none d-md-block" style="margin-top:18px;
