Definitions

  • This invention relates to propulsive cartridges for use in connection with mortar projectiles.
  • Projectiles adapted to be fired from mortars which are provided with stabilizing tails and with propulsive cartridges which fit around that portion of the tail which is comprised between the body of the projectile and the stabilizing surfaces, and which can be placed in positionon said tail.
  • said cartridges are constituted by annular cases containing the powder and, in order to enable such cartridges to be placed in position, the tail of the projectile must be previously detached from the body, so that the cartridge can be threaded over the front end of the tail, which latter has 'then to be screwed onto the projectile.
  • the present invention aims at providing a propulsive cartridge which, whilst preserving a substantially circular form, can be placed directly around the projectile without requiring the tail to be detached beforehand.
  • the cartridge. of the invention is subdivided into constituent charges, and is constructed after the manner of an elastic arch, the
  • constituent charges composing the arch being attached together by elastic connections in such a manner that the arch is capable of resilient expansion, to fit above the stabilizing fins and 30 to grip the stabilizing tail when in position.
  • Fig. 1 is an axial section of the rearward por- 40 tion of awinged projectile carrying a propulsive cartridge according to the invention
  • Fig. 2 is a section, on a larger scale, along the line 2-2 of Fig. 1.
  • the body I of a pro- 45 jectile is prolonged, in the rearward direction, by a tail 2, on the extremity of which are mounted fins 3.
  • the propulsion is effected in known manner by the aid. of an ordinary cartridge 4 introduced 50 and frictionally held in the tail 2. Lateral openings 5 are provided in the tail 2 to enable the gases to escape.
  • a variable number of propulsive relays or in- 55 crements, formed by a combustible casing containing a supplementary charge, are disposed on the tail 2.
  • relays are constituted by two or more members 6 in the form of cylindrical crown segments, with rounded ends, resembling the shape 6 crown segments is less than the external diameter 15 of the fins 3, and hence these fins prevent the relays from slipping backward off the tail.
  • Thecartridge and the number of relays required for attaining the desired range is placed in position in the mortar and the shot is fired by. the permission of the cartridge 4.
  • the gases" escaping through the openings 5 set fire to the relays or increments 6 so that the gases from these increments or relays cooperate with those of the cartridge 4 to drive the projectile, by acting on its rear face. Since the relays have been placed, not on the fins, but in front thereof, their deflagration cannot damage the fins, which are consequently not exposed to any risk of distortion.
  • a propulsive cartridge for projectiles comprising at least two casing members for containing the propellant, and resilient means connecting the adjacent ends of said cartridge members with the exception of one pair of the adjacent ends of two such casing members which remain free, said resilient means urging the said one pair of adjacent ends the one towards the other.
  • a propulsive cartridge for projectiles comprising at least two casing members, said casing members having rounded adjacent ends and resilient means connecting the adjacent ends of said cartridge members with the exception of one pair of the adjacent ends of two such casing members which remain free, said resilient 5 I means urging the said one pair of adjacent ends the one towards the other.
  • said resilient means tending to maintain the members in the form of a cylindrical crown hav iing'an internal "diameter less than'the outer diameter of the fins'and operating during the plat:-
  • a propulsive cartridge for projectiles comprising at least two propellent elements, and yielding means connecting adjacent ends of said elementsat one pair of ends, said yielding means "permitting separation of free adjacent ends of said elements-and" normally operating to hold saidfree ends close together in'the form of a cylindrical:crown.
  • Apropulsive cartridge for projectiles comprising a plurality of easing members for containing the propellant; andyielding means 'connecting all except onegpair of adjacent ends of said casing members, said means permitting separation of the saidcne pair. of adjacent ends and normallyi'operating to hold said pair of ends close together.
