NASA reload program

Atlantic Research Corporation (ARC) contracted with NASA to manufacture and deliver thirteen small scale Solid Rocket Motors (SRM). These motors, containing five distinct propellant formulations, will be used for plume induced radiation studies. The information contained herein summarizes and documents the program accomplishments and results. Several modifications were made to the scope of work during the course of the program. The effort was on hold from late 1991 through August, 1992 while propellant formulation changes were developed. Modifications to the baseline program were completed in late-August and Modification No. 6 was received by ARC on September 14, 1992. The modifications include changes to the propellant formulation and the nozzle design. The required motor deliveries were completed in late-December, 1992. However, ARC agreed to perform an additional mix and cast effort at no cost to NASA and another motor was delivered in March, 1993.
