Abstract : A study was conducted to determine the feasibility of employing a mechanical timer in a spin environment when all components are mounted off the axis of rotation. It is necessary, for practical purposes, to consider a range of spin radii and speed, so for this study the upper design limits were 2.5 inches and 16,000 rpm. Results of this study indicate that the device designed for this program will operate in the required environment, but additional effort is necessary to establish timing accuracy and to eliminate deficiencies.
