Definitions

  • the present invention relates to a rotor for a centrifugal launcher.
  • centrifugal launcher in the context of the present a machine comprising a rotating part or rotor driven at high speed around an axis of rotation and equipped with means for successively bringing projectiles into the central area of the rotor to be substantially radially ejected from the latter by centrifugal force.
  • Spherical projectiles nevertheless have considerable limitations in the military field: limitation of the speed of ejection; unfavorable ballistic qualities; practical impossibility of being provided with explosive charges, etc.
  • a centrifugal rifle extending from a cylindrical annular chamber and tangentially to the latter.
  • the assembly is mounted for rotation about the axis of said chamber.
  • the latter and the axis of said barrel are therefore two left rights.
  • Oblong projectiles, substantially in the form of a teardrop are successively ejected from a magazine in said annular chamber, a fixed stop being provided to prevent a projectile projected in said chamber from accompanying it in its rotation, this causing the projectile to enter said barrel.
  • the object of the invention is to provide a rotor allowing the launch at very high speed, in good conditions, of oblong projectiles whose shape is extremely close to that of conventional shells (that is to say with tail, body and ogival head).
  • a family of suitable projectiles in the context of the present invention is described in a joint application filed by the same Applicant (EP-A-53421).
  • a rotor according to the invention of the type with a cylindrical barrel rotating around an axis, is characterized in that said barrel is clamped between two flanges mounted at the end of a drive shaft, these flanges having a free central space into which ends the end of the barrel closest to the axis of rotation.
  • This internal end of the barrel is extended by a picking pallet extending as close to the axis of rotation of said rotor.
  • the presentation device is not part of the invention. As an indication, reference can be made to request 82201489E from the same Applicant.
  • cylindrical barrel is meant, in the context of the present, a tubular or semi-tubular barrel with a straight axis or substantially such.
  • the launcher shown comprises a rotor 1 constituted by two flanges 2 and 3 bolted to each other and enclosing a cylindrical barrel 4. This assembly is mounted and the end of a shaft 5 carried by bearings supported by a frame 6. This shaft 5 is capable of being driven by a motor, not shown.
  • the flanges 2 and 3 are each provided with a central bore, which leaves a free space 7 in the center of the rotor. In this space is engaged the end of a supply and presentation device, shown diagrammatically at 8.
  • the barrel 4 is arranged between the flanges 2 and 3 so that its axis X-X and the axis of rotation Y-Y of the rotor are two left straight lines.
  • the projections of these straight lines in the plane of Figure 2 are also perpendicular to each other.
  • the barrel 4 has a length such that its end closest to the YY axis ends in the escape 7. This end is provided with a picking pallet 9 which is in fact an extension of part of the wall of the .canon 4, of a width slightly less than the caliber of the projectiles 10. The length of said pallet is slightly greater than the distance separating the center of gravity of a projectile 10 from the tip of its warhead.
  • the device 8 comprises a magazine 11 in which projectiles 10 are aligned side-by-side and pushed back towards a stop 12.
  • a projectile applied against the stop 12 is immediately supported by the pallet 9 which, in its rotation, comes to pick up tangentially and remove it between the stop 10 and the supply of the next projectile.
  • the rotor rotates clockwise and, in its rotation, the pallet 9 is placed between the axis of rotation YY and the projectile for pick the latter.
  • the rotor is surrounded by two protective flanges 13 and 14 carrying a correction device 15 necessary to bring the axis of the projectile onto the trajectory of its center of gravity at the time of ejection.
  • the barrel is a cylindrical steel tube, which is the preferred solution. It could however be replaced by a semi-cylindrical blading, without departing from the scope of the invention.
  • a rotor according to the invention with a diameter of 950 cm, rotating at a speed of 12,443 rpm allows to communicate to a projectile an ejection speed of 800 m / s.
