Definitions

  • the rear casing 20 is movable axially within the front casing 2
  • the rear portion of the casing 21 is provided with four apertures 2% to allow for the escape of the gases generated by the burning of the propellent composition in the casing 2
  • the casings 2! and 20 may be charged with propellent and smoke-producing composition in exactly the same way as the casings I and 2 in Figures 1 to 5.
  • both compositions may be of the kind which burn inwardly from the outer surface, instead of outwardly as in Figures 1 to 5.
  • the propellent composition 25 is in the form of a. pressed cylinder which is held in spaced relation to the casing 21 by means of bands; 26. surrounding the composition 25 and provided with projections 27 to form spiders.
  • the pressed cylinder 23 of smoke producing composition is similarly supported in the casing by means of spiders 29. Ignition of the compositions andi28 is effected by means of fuzes 30 and 3
  • the fuze 30, which is attached to the rear end of the composition 25, passes through an orifice in the conical plug 32, through the space between the composition 28 and the casing 20 and out through an orif ce in the choke collar [4 on the rear casing I is provided with two further sleeves 34 in which are rigidly secured rods 35.
  • the sliding tail in this instance is formed of a band 4! slidable on the casing 20 and joined by three bars 42 to a wider band 43. Slots 44 are provided inthe annular stop 23 to accommodate A flange 45 is provided at the rear end of the casing 20 to act as a stop to limit rearward movement of the sliding tail on the casing.
