C-5A Ground-Flotation Tests on a Landing Mat Runway (Civil Engineering Support).
Abstract
The effect of C-5A operations on the Tri-Service landing mat runway at Dyess AFB, Texas, is described. Runway condition before, during, and after flight tests is given. The magnitude and effects of jet blast damage, lateral and longitudinal mat movement, runway bow and bow waves are described. Large quantities of debris were deposited on the runway because of jet blast. The jet blast dislocated a portion of a mat taxiway interconnect. Lateral mat movement was severe in turnaround areas. Longitudinal mat movement resulted in a bow in the plane of the mat which caused mat end connector failures. 5ongitudinal movement up to 33 inches in one landing resulted in bow waves which caused severe mat failure in the runway at three separate locations during one landing. In its present configuration the Tri-Service landing mat runway is not suitable for future tests. A theoretical and model analysis of the dynamic multi-wheel heavy gear loads of the C-5A Galaxy on aluminum landing mats is proposed. (Author)
