Abstract:

The purpose of the study reported was to obtain data to validate or modify, if necessary, existing criteria for the operation of the C-5A aircraft on unsurfaced airfields. Two specially prepared test sections were constructed and trafficked. Test section 1 consisted of a three-item test lane designed for evaluation of surface strength requirements and was trafficked with a 12-wheel C-5A gear arrangement loaded to 252,00 lb. Test section 2 consisted of two traffic lanes lanes 1 and 2 of four items each designed for evaluation of thickness requirements. Lane 1 was trafficked with a 35,000-lb single-wheel load, and lane 2 was trafficked with the 12-wheel C-5A gear arrangement. An analysis of the test data showed that existing criteria could be used to design unsurfaced airfields for operations of C-5A aircraft.
