Abstract:

Results of recent tests on the thermal conductivity of Pershing propellant are included in the report. These tests were performed at the Propulsion Laboratory of the Army Missile Command, Huntsville, Alabama. A transient heat transfer system has been constructed and tested in an attempt to determine the thermal diffusivity of solid propellant. Details on the construction and calibration of the apparatus are given in the report. Also, thermal conductivity has been determined for an inert propellant sample by the line-source and steadystate methods used previously. The density of the specimen was measured and the specific heat was calculated in order to provide a complete thermal analysis. Derivation of a series solution for the problem of transient heat flow in a semi-infinite solid is given in an appendix. The equations are programmed so as to obtain a trial-and-error solution for the thermal diffusivity. Author
