So, these tests were very helpful,&#8221; Lin said.<\/p>\n<p>Completing the tests marks another milestone off the checklist of things to do before the X-59 makes its first flight this year, continuing NASA&#8217;s Quesst mission to help enable commercial supersonic air <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/trip-and-travel\/\" data-internallinksmanager029f6b8e52c=\"10\" title=\"Trip &amp; Travel\" target=\"_blank\" rel=\"noopener\">travel<\/a> over land.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Simulating_the_sky\"><\/span>Simulating the sky<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>During the testing, engineers from NASA and contractor Lockheed Martin turned on most of the X-59&#8217;s systems, leaving the engine off. For example, if the pilot moved the control stick a certain way, the flight computer moved the aircraft&#8217;s rudder or other control surfaces, just as it would in flight.<\/p>\n<p>At the same time, the airplane was electronically connected to a ground computer that sends simulated signals\u2014which the X-59 interpreted as real\u2014such as changes in altitude, speed, temperature, or the health of various systems.<\/p>\n<p>Sitting in the cockpit, the pilot &#8220;flew&#8221; the aircraft to see how the airplane would respond.<\/p>\n<p>&#8220;These were simple maneuvers, nothing too crazy,&#8221; Lin said. &#8220;We would then inject failures into the airplane to see how it would respond. Would the system compensate for the failure?

But since the X-59 is a one-of-a-kind airplane, officials decided it was better and less expensive to use the aircraft itself.<\/p>\n<p>As a result, engineers dubbed this series of exercises &#8220;aluminum bird&#8221; testing, since that&#8217;s the metal the X-59 is mostly made of.<\/p>\n<p>So, instead of testing an &#8220;iron bird&#8221; with copies of an aircraft&#8217;s systems on a non-descript frame, the &#8220;aluminum bird&#8221; used the actual aircraft and its systems, which in turn meant the test results gave everyone higher confidence in the design.<\/p>\n<p>&#8220;It&#8217;s a perfect example of the old tried and true adage in aviation that says &#8220;Test what you fly.
