Cast Perchlorate Propellants Based on Thermosetting High Polymers
Abstract
The Galcit propellants developed at the California Institute of Technology are outstanding in their ease of preparation and in the simplicity of the equipment in which they are prepared. Compared with many propellants they have the further major advantage of a low temperature coefficient. They have, however, shown deficiencies when used at very high or very low temperatures of a kind which are probably unavoidable in a material of a pitchy or asphaltic nature. Such materials become soft enough to flow at high temperatures and become hard and brittle at low ones. Work in this laboratory on binders for composite propellants (OSRD Report No. 5586) had shown that long chain high molecular weight polymers and especially elastomers have physical properties which are much less sensitive to temperature than are pitches and tars. Consequently investigation was started the latter part of 1944 looking toward the development of a castable propellant composed of a mixture of potassium perchlorate with some suitable high polymeric material.
