AlRCRAFT (FULL-SIZE GLIDER) CRASH-WOHTHINESSS IMPACT TEST

Anthony Segal

Abstract


The purpose of the test was to record the forces acting on a full-size glider, a pilot manikin, and the seat harness in a representative crash. A pendulum testrig was used. High peak g loadings of short duration were recorded on the airframe and the pilot manikin. Energy was absorbed by deformation and delamination of the GRP fuselage. There was a failure in tension at the junction of a forward transverse bulkhead and the fuselage side-wall. There was considerable loading on the seat hamess lap srap. The pilot manikin 'submarined' down and forward under the seat harness. This demonstrated that five or six point seat harness should be fitted.
