Air Force Dynamic Mechanical Analysis Testing of NATO Round Robin Propellant Testing for Development of AOP-4717

Abstract

In late July and early August of 2015, the Air Force Research Laboratory (Propulsion Division) performed testing on an inert propellant previously provided by Naval Air Warfare Center Weapons Division (NAWCWD). The purpose of the tests was to participate in an international round robin that would have as its main goal standardization of dynamic mechanical analysis (DMA) testing of solid rocket propellants. The standardization of these types of tests (as they apply to propellants) will become part of AOP-4717, an overarching NATO document that includes other propellant testing protocols. Due to resource limitations, the reduced protocol was followed. The tests are best described in two parts: the following section describes the strain sweep tests, which are a necessary precursor to the frequency sweep tests. After these strain sweep tests are described, the frequency sweep tests are explained. Since the experimental apparatus is common to both test types, however, this is described next.
