High-speed cameras filming at 500 images per second track each dot, so after over the drop researchers can plot and see exactly how the fuselage buckled, bent, cracked or collapsed under crash loads.Īnother crash test of a similar helicopter equipped with additional technology, including composite airframe retrofits, is planned for next year. Technicians painted one entire side in black polka dots over a white background - a photographic technique called full field photogrammetry. ![]() The outside of the fuselage also is new for this test. “We want to see if it is useful as an additional way to track the movements of the dummies,” said test engineer Justin Littell. The impact condition represents a severe but survivable condition under both civilian and military requirements.įor the first time ever in any test, technicians installed a video game motion sensor in the helicopter. The helicopter will hit the ground at about 30 miles an hour. Just before impact, pyrotechnic devices release the suspension cables from the helicopter to allow free flight. ![]() During the test, onboard computers will record more than 350 channels of data as the helicopter is swung by cables, like a pendulum, into a bed of soil. ![]()
