³§³Ü³¾³¾²¹°ù²â:ÌýThe Dream Chaser reusable spacecraft prototype was load tested in two configurationsÌýto validate analytical models of the vehicle.ÌýIn the first, the modular test system was configured to apply loads to the landing gear struts in a simulation of touchdown during landing.Ìý For the second, the test system was configured to apply loads to the connections for the solid rocket motors in a simulation of ascent to orbit. Over 200 strain gauges and other displacement and force instrumentation were used during loadingÌýand compared in real time to model predictions. Engineers monitored the comparisons and were able to halt the test if localized strains were exceeding safety limits.
