W2SD-19 Structural Development Test Case M215.06
Abstract
Structural development test W2SD-19, Case M215.06 was conducted at the Bacchus Works, HES Pow der Company, 26 April 1962 to determine the structural integrity of the Wing II M-57E1 motor case when subjected to combine flight load conditions of axial load, shear load, and bending moment at room temperature. Case M215.06 failed under the combined effects of an axial load of 24.38 kips, a shear load of 9.285 kips, and a bending moment of 883.5 in.- kips, all which were in excess of required flight design loads. These applied loads were calculated at the forward tan gent line where the failure occurred. From the test results, it was determined that the equivalent axial load was 129.62 kips and that the mode of failure was a circumferential buckling of the forward skirt at the forward tangent line. It was concluded that the Wing II design is capable of withstanding the present flight performance requirements as defined by Boeing document D2 3877-4. The safety factor, in excess of the de sign criteria, was determined to be 1.51.
