Structural static test was conducted on the CFRP composite co cured MLG(Aft) door to demonstrate the structural integrity of the door and to experimentally determine the deflections and strains at selected locations and to correlate the test values with those obtained by theoretical values. The door was loaded for two pressure load cases and two suction load cases. Pressure load cases are limit load cases. One suction load case corresponds to Design ultimate load case and the other suction load case corresponds to jamming load case. The load v/s deflection/strain behavior was obtained for all load cases. The door successfully withstood the ultimate load without any failure and the maximum deflection was 11.26mm and the maximum strain was 1681 micro strains. Both deflections and strains were well within the design requirements. It was therefore concluded that the structural behavior of the door is satisfactory and it was cleared for flight trials. This report deals with the results of the static testing of the door.
