LONG RANGE STUDY OF PREDICTION OF SAFE LIFE OF PROPELLANTS
Abstract
A long range storage program on many of the standard modern propellant formulations is being conducted at Picatinny Arsenal. Propellant samples are conditioned at temperate, tropical, desert, and laboratory controlled accelerated conditions. Standard and experimental testing techniques are employed to determine the safe life potential of each study propellant, and in turn the test methods are being evaluated as to their applicability for establishing stability potential. It has been shown that stabilizer analysis is an effective means for determining the chemical stability of propellants, however, an analytical problem does exist with ethyl centralite. The 65.5 C. Surveillance Test and Propellant Quick Test both appear to be suitable surveillance tools, however, both have short comings. The Methyl Violet Heat Test has limited value for estimating stability potential of an aged propellant, and the Vacuum Stability and Taliani Tests to date have not proven to be beneficial. The Viscosity Test results continue to show promise, and appear to correlate well with the other more reliable testing techniques. A better comprehension of propellant safe life concepts is being realized through the study of the test results of each propellant formulation under study.
