QUALIFICATION TESTS OF THIOKOL CHEMICAL CORPORATION TE-M-364-3 SOLID- PROPELLANT ROCKET MOTORS TESTED IN THE SPIN AND NO-SPIN MODE AT SIMULATED ALTITUDE CONDITIONS (PART 1 - INITIAL PHASE)
Abstract
Two Thiokol Chemical Corporation TE-M-364-3 solid-propellant rocket motors were qualification tested at average pressure altitudes of about 104,000 ft. The motors were temperature conditioned at 75 plus or minus 3 F. One motor (S/N T00004) was fired in the no-spin mode, and the other motor (S/N T00005) was fired while spinning about its axial centerline at 110 rpm to determine altitude ballistic performance, tailoff characteristics, temperature-time history during and after motor operation, component structural integrity, and nonaxial thrust of the spinning motor. Vacuum specific impulse values based on the manufacturer's stated propellant weight were 290.86 (S/N T00004) and 291.14 (S/N T00005) lbf-sec/lbm. Both motors maintained structural integrity throughout their entire burn time. However, the fiber glass band located at the nozzle exit plane became completely detached 34 sec after ignition of motor S/N T00004 and partially detached 29 sec after ignition of motor S/N T00005.
