ILIR Task of Digital Recoil Travel Measurement System,

reportActive / Technical Report | Accession Number: ADA147102 | Open PDF

Abstract:

A study was conducted to improve measurement of large caliber weapon recoil travel. Since the 1950s, a continuous rotation, single turn potentiometer driven by a rack and pinion gear has been used on a variety of weapons. Satisfactory data has been produced by this system, but the data records suffer from a number of problems caused by the potentiometer. Therefore, the potentiometer was replaced by a digital incremental optical shaft encoder. Circuitry was developed to interface the encoder output to a digital data acquisition system. Software was then written to process the data at the firing site, and provide a near real-time plot of recoil travel and velocity versus time. Originator supplied keywords include Ballistic Test Site Terminal, and Incremental Optical Encoder.
