Structural Analysis and Fatigue Test of the Ranger Anti-Armor/Anti- Personnel Weapon System (RAAWS)

Abstract

The Ranger Anti-Armor/Anti-Personnel Weapon System (RAAWS) was investigated to determine its structural strength and fatigue life. The RAAWS is an 84-mm lightweight, shoulder-Fired recoilless weapon produced by FFV Ordnance, Sweden. The tube consists of a thin steel rifled liner overwrapped with a graphite/epoxy composite jacket. This investigation includes a finite element stress analysis, firing tests, laboratory strain and material property tests, and fatigue tests to determine the interim safe fatigue life for the weapon. Ranger Anti-Armor/Anti-Personnel Weapon System(RAAWS), Recoilless rifle, Composite gun tube, Fatigue tests, Finite element stress analysis, Firing tests, Strain measurements, Material tests, Chemical analysis, Thermogravimetric Analysis, Differential scanning calorimetry.
