Inertial Upper Stage Thermal Test Program
Abstract
An extensive thermal testing program was performed in an arc tunnel facility in support of an IUS second-stage solid rocket motor (SRM) requalification activity. A three-phase laboratory thermal study of failure scenarios resulted in the following items. First, bursting of the SRM environmental closure was pressure rather than temperature dependent, which allowed full-scale cold-gas simulation of the closure burst sequence. Secondly, arc tunnel ablation measurements of EPDM, a thermal insulative rubber material covering the SRM ignitor housing, were made in both convective and radiative heater environments under varied sample vibration levels to simulate the measured motor vibration environment.
