The Measurement of the Longitudinal Offset of the Centre of Mass of Chaff Dipoles.

Abstract

The distance between the centre of mass and the mid-point of aluminised glass chaff dipoles. Measurements were made of the longitudinal offset of chaff dipoles by encapsulating them in resin and taking multiple sections, measuring the area of the dipoles and the distance between sections. The position of the centre of mass was determined by taking moments of the elemental volumes so described about one end of each dipole. The measurements were made by photomicrography and manual analysis of the film since the characteristics of packed dipoles put the measurements outside the capabilities of computer based image analysers. The final result was that the offset was very small.
