Composite Universal Weapons Pylon Damage Tolerance

Abstract

Damage tolerance testing of the OH-58D Composite Universal Weapons Pylon (CUWP) commenced 07 May 2010 and was completed 25 May 2010. The damage introduced into the test article consisted of an asymmetrical hole bored into a critical section of the composite tube and also the removal of a critical fastener. The CUWP successfully met the cyclic, stiffness, and proof load requirements of the test plan. Visual inspection of the CUWP prior to testing and after all load applications were completed showed that no visible damage was introduced into the test article. The CUWP test article can be considered damage tolerant, to the extent of the damage introduced in the test article, up to four lifetimes of weapons firing on the OH-58D.
