Abstract
Weapon equipment including a launcher and a projectile, the projectile having an operating head, a tail and a weight between 750 g and 1000 g. The tail includes a tube made of an aluminum alloy having an inner diameter between 21.5 and 22.5 mm, a stroke between first and second locations between 110 mm and 120 mm, and a thickness in the vicinity of the first location between 4.6 mm and 5 mm, a piston movable between the first and second locations and defining with the tube a hermetically-sealed propulsion chamber, a propulsion charge placed in the propulsion chamber, the propulsion charge including a powder having a heat of combustion between 3500 J/g and 4000 J/g, the propulsion charge having a mass greater than 2.4 g and less than 3.7 g.
Claims20
Weapon equipment comprising a launcher and at least one projectile intended to be projected at a distance by the launcher,
- wherein the launcher comprises:
- a cylindrical barrel along a barrel axis, with the barrel comprising a housing adapted to receive at least one portion of the projectile, and a mouth adapted to allow for a passage of the projectile,
- a launch rod extending in the housing of the barrel along the barrel axis and having a free end facing the mouth of the barrel, the free end having a bearing surface and a recess arranged in the bearing surface,
- a percussion device comprising a percussion tip mounted to be movable in the launch rod between a retracted position, wherein the percussion tip is arranged in the recess, and a priming position, wherein the percussion tip protrudes in relation to the bearing surface,
- wherein the projectile has a weight between 750 g and 1000 g and extends along a projectile axis, the projectile comprising an operating head and a tail that extends the operating head along the projectile axis, the tail comprising:
- a tube adapted to be mounted on the launch rod, with the tube being made of an aluminum alloy and having an inner cylindrical surface of circular section along the projectile axis, the inner surface having a constant inner diameter over a stroke along the projectile axis between a first location located on a side of the operating head and a second location separate from the first location, the inner diameter being between 21.5 mm and 22.5 mm, the stroke being between 110 mm and 120 mm, the tube having a thickness in the vicinity of the first location between 4.6 mm and 5 mm,
- a sealing element closing the tube in a sealed manner in a vicinity of the first location,
- a piston placed in the tube in sealed contact with the inner surface of said tube and adapted to rest on the bearing surface of the free end of the launch rod, the piston comprising a primer arranged to be activated by the percussion tip in priming position when the piston is resting on the bearing surface of the free end of the launch rod, the piston defining with the tube and the sealing element a hermetically-sealed propulsion chamber, with the piston being placed at the first location and able to be moved to the second location,
- a propulsion charge placed in the propulsion chamber when the piston is at the first location and which can be activated by the primer of the piston in order to move the piston bearing on the bearing surface of the free end of the launch rod from the first location to the second location, the propulsion charge comprising a powder having a heat of combustion between 3500 J/g and 4000 J/g,
- a stopper element adapted to retain the piston in the tube at the second location,
- wherein the propulsion charge has a mass strictly greater than 2.4 g and less than 3.7 g.
Projectile specially adapted for weapon equipment, the projectile having a weight between 750 g and 1000 g and extending along a projectile axis, the projectile comprising an operating head and a tail which extends the operating head along the projectile axis, the tail comprising:
- a tube adapted to be mounted on a launch rod of a launcher, with the tube being made of an aluminum alloy and having an inner cylindrical surface of circular section along the projectile axis, the inner surface having a constant inner diameter over a stroke along the projectile axis between a first location located on a side of the operating head and a second location separate from the first location, the inner diameter being between 21.5 mm and 22.5 mm, the stroke being between 110 mm and 120 mm, the tube having a thickness in the vicinity of the first location between 4.6 mm and 5 mm,
- a sealing element closing the tube in a sealed manner in the vicinity of the first location,
- a piston placed in the tube in sealed contact with the inner surface of said tube and adapted to rest on a bearing surface of a free end of the launch rod of the launcher, the piston comprising a primer arranged in order to be activated by a percussion tip in priming position of a percussion device of the launcher when the piston is resting on the bearing surface of the free end of the launch rod of the launcher, with the piston defining with the tube and the sealing element a hermetically-sealed propulsion chamber, with the piston being placed at the first location and able to be moved to the second location,
- a propulsion charge placed in the propulsion chamber when the piston is at the first location and which can be activated by the primer of the piston in order to displace the piston bearing on the bearing surface of the free end of the launch rod of the launcher from the first location to the second location, the propulsion charge comprising a powder having a heat of combustion between 3500 J/g and 4000 J/g,
- a stopper element adapted to retain the piston in the tube at the second location,
- wherein the propulsion charge has a mass strictly greater than 2.4 g and less than 3.7 g.
