The Dispersion of and Dispersion Limits for the A. A. Fuze MK III with Recommended Dispersion Limits

Abstract

Causes of the dispersion in the time of flight of powder train fuzes are mentioned. It is shown that the dispersion of the A. A. Fuze Mk III can be considered to depend only upon the mean pressure along the trajectory. By the aid of this result, the dispersions are calculated as a function of elevation and fuze setting. Dispersion limits for specifications are recommended. No recommendations are made concerning calibration requirements for the fuze, since insufficiently complete data concerning the temperature of the fuze, the pressure of the atmosphere and the mean time of flight have been obtained from past firings.
