A study is made of the feasibility of applying the concepts of pneumatic timing to meet the requirements demanded of artillery fuzing including the establishing of the advantages and limitations of proposed pneumatic systems attempting to conform to typical artillery fuze specifications and the finding of indications of possible solutions to the various problems which may arise. System design, packaging, and environmental effects were studied, solutions were found to problems, and a complete feasible timer system was proposed, based on the results of these studies. A practical demonstration of the proposed timer was given by a working breadboard model and an end item size packaging model. The determination of the feasibility of the timer is substantiated by experimental evidence supported by theoretical considerations. The resulting fuze timer concept is a timer, settable in 0.1-second increments up to 180 seconds capable of packaging within a conventional artillery fuze contour, withstanding standard military tests, and capable of operating under conventional artillery projectile environmental conditions.
