ILLUMINATING SHELLS (fig. 303).
Description. - Illuminating shells include a steel shell body, with a screw base; it can be divided internally, by a steel frame, into several floors with several compartments. It is crossed by a central tube and sometimes a side tube.
Loading. - The lighting load is made up of one or more cylindrical stars with parachute, housed in the various compartments. The bursting and igniting charge consists of a warhead charge and a powder pellet charge. The central and side tubes can be fitted with a worm wick.
Painting and Marks. - The illuminating shells are entirely painted white. The loading marks are affixed to the warhead. Below these marks are 3 5-pointed stars, in bluish-gray, regularly spaced at the same height around the perimeter of the shell.
Priming. - The illuminating shells are armed with a non-detonator fusing rocket, some when loading, others when firing.
Operation. - The rocket sets fire, sometimes to the side tube and thereby to the base charge, to the central tube, to the warhead charge, sometimes to the warhead charge, to the central tube, to the base charge. The latter blew the nerve; the central tube ignites the stars; the warhead charge expels the stars through the base, the parachute envelopes remaining attached to the frame by wire. The stars shine like parachute fireworks.
Employment. - The use of illuminating shells includes the possible positioning, stripping and unblocking of the rocket.
