Engineers at NASA’s Armstrong Flight Research Center examined the X-56 Multi-Use Technology Testbed as the aircraft underwent “moment of inertia” testing in the center’s Flight Loads Laboratory (FLL).
The tests, which were the final series for the vehicle in the FLL, featured a swing test to determine how easy or difficult it is for the vehicle to pitch up or down. Tools to assist researchers during the tests included everything from a laser ball and tracker to a simple stop watch. Data from the tests will go towards updating the finite element model, bringing the team closer to possible flight testing.
