THERMAL STABILITY OF SOME NF PROPELLANTS.

Abstract

The efforts of these Laboratories in evaluating and improving the thermal stability of high energy NF propellant based on NFPA and TVOPA are summarized. Test methods are briefly described. Sufficient experimental results are included to demonstrate significant improvements which were achieved. Methods which led to these improvements are described; these include the use of an acrylic acid-diepoxide curing system, purification of TVOPA in an ion-exchange column, inclusion of a finely divided aluminum oxide as a coating for ammonium perchlorate, omission of FeAA curing catalyst, and elimination of volatile contaminants from the binder. The importance of storing propellant in a dry environment and the effect of high temperature mechanical strength on cube fissuring behavior are shown.
