Applied Research & Development of Triaxial Piezoelectric (PZL) Accelerometer Systems of Improved Design.

Abstract

Refinements in the accelerometer system used in the falling-sphere atmospheric density measuring system have been implemented. These include a redesigned Z-axis amplifier chain, range scale changes in the X and y axis amplifier outputs to provide overlap, and a new temperature monitor circuit. The squib initiation circuit and squib holder bushing has been redesigned for greater reliability. Calibration has been improved by the use of a specially-designed function generator. Five systems were fabricated. Three systems were flown at Kwajalein, M.I. and Red Lake. Canada. (Author)
