Delethalized Cyclic Control Stick.
Abstract
In November 1983, the final report for the initial crashworthy cyclic control stick effort was published. The report detailed the development and testing of a purely mechanical self-contained crashworthy cyclic control stick equipped with load-limiting and separating joint. The joint was to limit impact loads transmitted to a crewmember. This report covers the additional development and testing of this concept by Simula Inc. to further delethalize the separating crashworthy cyclic control stick. Using an impact load-limiting grip pad and reduction of the moving mass to reduce the inertial forces, two configurations were subjected to static and dynamic pendululm testings. Additional destructive static tested in a full-scale dynamic test using an anthropomorphic dummy and a vertically stroking UH-60A Black Hawk crewseat. Testing demonstrated that the delethalized stick worked as intended when struck by the dummy. It also showed that the loads transmitted to the dummy were far less than with conventional sticks.
