AIRCRAFT GROUND-FLOTATION INVESTIGATION PART III. DATA REPORT ON TEST SECTION 2
Abstract
A description is presented of work undertaken as part of an overall program to develop ground-flotation criteria for the C-5A aircraft. A test section was constructed to a width adequate for two similar test lanes. Each lane was divided into three items having different subgrade CBR values and different traffic surfaces. Item 1 was surfaced with modified T11 aluminum landing mat, item 2 with M8 steel landing mat, and item 3 remained unsurfaced. Traffic was applied to one lane using a 35,000-lb load on a single-wheel assembly consisting of one 56x16, 24-ply aircraft tire inflated to 100 psi. On the other lane a twin-wheel assembly (loaded to 70,000 lb) consisting of two 56x16, 32-ply aircraft tires spaced 25 in. c-c and inflated to 110 psi was used. Presented is a description of the test section and wheel assemblies, and results of traffic. The traffic-coverage level at which failure was evidenced on each test item is also given.
