THE TEMPERATURE DISTRIBUTION IN A CASE BONDED CYLINDRICAL ROCKET ASSEMBLY
Abstract : Equations are presented for the temperature distribution in a case bonded propellant grain when the environmental temperature is suddenly changed. It is found that whenever the Biot modulus is relatively small, the temperature distribution is essentially independent of the radial coordinate but varies with the time coordinate only, at a rate which is dependent upon the geometry and the physical properties of the propellant grain as well as the heat transfer coefficients.
