International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada === The demand for test projectiles instrumented for gathering in-bore torsional impulse data has been steadily increasing. A test projectile consists of a telemeter, 12 accelerometers, and the remaining necessary hardware. Cost, availability, and survivability of commercial accelerometers being used have become a major concern. In-house testing of a new source and different technology accelerometer show a cost benefit, higher availability and a much higher survivability rate. This paper outlines the recent progress of qualifying a new source and different technology accelerometer, which leads to a modification of the current Torsional Impulse test projectile, along with potential developments to insure a more cost effective, available, and reliable test projectile to be used in future torsional impulse tests.
