The purpose of this program is the development, design, fabrication, and demonstration of packageable, highexpansion-ratio nozzles for solid propellant rocket motors. The program is to be accomplished by conducting 1 a design and analysis program adapting liquid technology to solid propellant motors 2 a subscale test program to verify the selected designs and 3 a demonstration test program that will utilize the test experience of the subscale program and demonstrate the feasibility of elastomeric and metallic packageable exit cones for solid motors. During this report period the subscale test program was successfully completed. On the demonstration program the progress was as follows the design was completed on the metallic and elastomeric exit cones the first four motors have been cast, the second motor has a bond separation and will require refurbishing the igniters have been completed and the nozzles are partially fabricated.
