Available in PDF, EPUB and Kindle. Book excerpt: After a buckling failure in a section of AM2 landing mat runway during a test landing of a C-5A at Dyess AFB, Texas, in August 1970, a model testing program was initiated. This report presents the results of the development and testing of an analytical model and a 1/7-scale physical model AM2 mat runway subjected to C-5A loadings. The analytical model represents the landing mat as a series of discrete rigid elements interconnected and suspended by springs and dashpots subjected to external forces simulating Coulomb friction, shear, and the action of the aircraft. Results from the computer program developed included a simulation of the Dyess failure and an evaluation of various mat modifications. The 1/7-scale physical model of the C-5A landing gear produced buckling failures in the model AM2 mat runway similar to the failure that occurred at Dyess AFB. (Modified author abstract).

Available in PDF, EPUB and Kindle. Book excerpt: A series of model C-5A landing tests on 4 by 4.5 ft. and 2 by 9 ft. Dow truss web landing mat runways were studied using a 1/7 scale physical model. Model landing mat units were constructed of extruded aluminum joint edges bonded to a foam core fiber glass panel. Simulated landings were made on 14.5 by 128 ft. mat runways. The model 4 by 4.5 ft. mats were tested in four runway laying patterns. Laying patterns without a transverse hinged joint formed the most stable runway. When laid in the standard brick pattern with a transverse hinged joint, the 4 by 4.5 ft. mat runway was more stable than the 2 by 9 ft. mat runway. The 2 by 9 ft. mat runways were tested only in the standard brick pattern. Restraint at the runway edge did not prevent buckling of the 2 by 9 ft. mat runway in the standard brick pattern. tension anchors at the touchdown end of the runway controlled the longitudinal displacement and prevented buckling of both mat types when laid in the standard brick pattern. The use of end anchorage appears to be a practical method to reduce mat runway maintenance and prevent buckling failure. (Author).
