Abstract:  
Some unique testing methods in connection with static load application and associated data acquisition are described. The "free-flilght" method of airplane static testing is covered as it applies to the current test program for the C-133 Cargomaster (300,000 lb gross weight). The loading and safety advantages of the single pressure concept are discussed. Instrumentation provides for visual readout as well as IBM bunch cards for records of deflection, cabin pressures, jack loads and up to a total of 2800 strain gage installations. Use of the Electromec and safety methods for fuselages pressurized by air are discussed. Additional areas that are covered: Hydrostatic-test methods and instrumentation; fail safe development for pressureized cabins; and future of fatigue tests of a complete airplane.
