20MM Extended Range Tracers.
Abstract
The design of the tracer projectiles consists of a single cavity at the base of the projectile containing the consolidated pyrotechnic formulation. The visible range of trace along the projectile's trajectory is dependent upon the chemical composition of the pyrotechnic mixture as well as the available length (or depth) of the tracer cavity. In the 20mm projectile, the tracer cavity has been modified by the incorporation of an aluminum multi-cavity capsule, called 'folded cavity', to extend the average visible range from the current 1800 meters to 3500 meters. This breakthrough has extended the burning time and hence the visible range without lengthening the available tracer cavity and without compromising other ammunition performance characteristics (such as ballistic stability in flight).
