Development of CBR Design Curves for Harvey Aluminum Landing Mat

摘要

The report describes a study conducted to develop CBR design curves for an aluminum landing mat. The design curves were to represent 1600 operational cycles of an aircraft having a 60,000-lb gross weight with a single-wheel main gear assembly load of 27,000 lb and a 30-7.7 tire inflated to 400 psi. CBR design curves were also desired for 1600 passes of a 39,000-lb single-wheel load applied in a single track to represent the calculated loading imposed on the landing mat during launching of the 60,000-lb aircraft by catapult.
