Automated Peak Chamber Pressure Measurements System (APCPMS).

Abstract

The Automated Peak Chamber Pressure Measurement System (APCPMS) was designed, built, and programmed to measure the height of the crushed copper spheres which is a function of the internal peak chamber pressure generated during weapon firing programs. A trial test was conducted with a sample size over a predetermined pressure range window. Results were compared with previously used measurement methods. By eliminating operator-error factors, the APCPMS demonstration that it was a more reliable and accurate means of obtaining peak chamber pressure measurement data. It was recommended that another computer system be used to improve visibility of display, and a more extensive test be conducted over a wider pressure range. The APCPMS consists of the following components: a gaging fixture (LVDT), a microcomputer based controller, and a printer. Keywords: Automated peak chamber pressure; Measurements system; Linear variable differential transformer; Chamber pressure measurements; Copper crusher.
