Definitions

  • the present invention relates to airplanes provided with an automatic firearm and it is more especially, although not exclusively, concerned with airplanes provided with a firearm of the so-called open breech type, that is to say in I which the breech is open when the arm is ready for firing.
  • the object of the present invention is to-provide an airplane of this kind which is. better adapted to meet the requirements of practice.
  • the essential feature of the present invention consists in so arranging the firearm to be carried by theairplane as above stated that one of the parts of said firearm is fixed to one spar of the wing, while another part of the firearm is supported through means permitting axial movement of the firearm but in substantially fixed position with respect to the structure of the wing.
  • Fig. l diagrammatically shows the arrangement of a gun in the wing of an airplane, accordin to the present invention
  • Fig. 2 shows, on a larger scale, a vertical section through the axis of the gun tube of the device for fixing the gun to the wing according to the invention
  • Fig. 3 shows, also on a larger scale, a section, on the line III--III of Fig. 1, of the connecting device provided between the structure of said wing and the rear part of the gun.
  • the airplane proper may be of any type whatever, provided that the wing I in which the gun is to be mounted includes at least one main lateral member or spar.
  • the automatic gun 2 (preferably the barrel thereof) is fixed to this spar (or tonne of the'spars if the wing includes several of them, and in this case preferably to the front one).
  • this spar or tonne of the'spars if the wing includes several of them, and in this case preferably to the front one.
  • the whole of the automatic gun is housed insidethe wing, as diagrammatically shown in the View of Fig. 1.
  • a device 3 adapted to keep the axis of the gun in substantially fixed position with respect to the wing structure.
  • this device is so made, in the known manner,
  • the wing includes two spars, or main lateral members, such as 4 and 5, and when the barrel of the gun is fixed to the front spar 4, the above mentioned device 3 preferably will be fitted on the rear spar 5.
  • the barrel of the gun might be rigidly fixed to spar 4.
  • a fixation system ensuring axially, and at least in one direction, a certain elasticity between the gun and the spar, in order to protect the wing structure against recoil effects and other normal and abnormal effects resulting from the firing of the gun.
  • I provide, on at least one side of said guiding means, and preferably on both sides thereof, an elastic system, having preferably a certain compression in the state of rest, adapted to elastically maintain the gun barrel in position by applying against a stationary stop a projection carried by said gun barrel.
  • spar 4 carries a guiding member 6 the axis of which is parallel to the desired direction of firing.
  • this guiding member consists of a ring having a rear face I and a front face 3 and fixed on spar 4 by means of bolts.
  • a sleeve S provided, at its front end, with a flange 10 adapted to butt against the edge 8 of guiding member 6.
  • This sleeve 9 extends, for instance, a little beyond guiding member 6, toward the rear, and its inner diameter is so chosen that the barrel l of the gun can slide therein with a working flt.
  • the barrel is provided, at a suitable point thereof, with a stop II.
  • I further provide, on said barrel, a sleeve l2 provided, at its rear end, with a flange l3 adapted to be applied against stop I i. Between said flange l3 and edge I, I insert at least one spring H, or preferably a plurality of springs, each mounted in a housing provided in the front face of flange I 3.
  • I flx on guiding member 6 an adjustable stop adapted to coact with the rear face of flange l3.
  • this stop consists of the flat end of a cap I8 provided with a hole adapted to accommodate the gun barrel and screwed on a tubular part l5 carried by edge I of member 6, this part I! and said cap it forming together a kind of casing in which springs M are enclosed.
  • the various elements of the fixation device above described are so dimensioned that the elasticity of the elasticsystem corresponds to the working that will be hereinafter described, and that, preferably, in the state of rest, the rear, edge of sleeve 9 is in contact with the front edge of sleeve i2.
  • a strong spring I! is inserted between flange i0 and a stop I 8 fixed to the part of the gun barrel I located in front of said flange.
  • this stop is a stop,
  • a nut l9 which may be, for instance, rigid with a fire protector 20 extending preferably as far as the leading edge 2
  • Spring i1 is given a certain initial compression preferably greater than the recoil force transmitted to the gun barrel, and equal for instance to-- I of this force.
  • springs i4 their function is to absorb the shocks due to the return of the organs of the gun into firing position.
  • An airplane which comprises, in combination, a wins. a wing frame, two spars in said wing frame located one behind the other, a gun mounted in said wing, a guiding member carried by the front spar, a sleeve mounted in said guiding member with a working flt and surrounding the gun barrel, which is mounted therein with a working flt, a flange on said sleeve at the front end there- 'of, a projection on said gun barrel, a spring interposed between said projection and said flange, and means carried by the other spar for slidably guiding the rear part of the gun so as to keep the axis thereof parallel to the direction in which the barrel of the gun' is allowed to slide in said sleeve.
  • An airplane which comprises, in combination, a wing, a wing frame, two spars in said wing frame located one behind the other, a gun mounted in said wing, a guiding member carried by the front spar, a sleeve mounted in said guiding member with a working flt and surrounding the gun barrel, which is inserted therein with a working fit, a flange on said sleeve at the front last mentioned flange and the rear face of said guiding member, and means carried by the other spar for slidably guiding the rear part of the gun so as to keep the axis thereof parallel to the direction in which the barrel of the gun is allowed to slide in said sleeves.
  • An airplane according to claim 2 further including means carried by said guiding member for adjusting the initial compression of the second mentioned spring.
  • a wing In an airplane, a wing, a wing frame, at least one spar in said wing frame, a gun carried by said wing, means for flxing a part of said gun to said spar in such a manner that said part and said spar will be rigid at least on normal firing, and means carried by said wing for guiding another part of said gun in such a manner as to permit axial displacements of said other part, both of said means acting to maintain the axis of the gun in a substantially fixed position with respect to said wing.
  • a wing In an airplane, a wing, a wing frame, two spars in'said wing frame located one behind the other, a gun carried by said wing, means for flxing a part of said gun to the front spar in such a manner as to prevent axial displacements of said part at least on normal firing and recoil and means carried by the other spar for guiding another part of said gun in such a manner asto permit axial displacements of said other part, both of said means acting to maintain the axis of the gun in a substantially fixed position with respect to said wing.
  • a wing In an airplane, a wing, a wing frame, at least one spar in said wing frame, a gun with a barrel carried by said wing,.means for fixing the barrel to said spar in such a manner as to prevent axial displacements of said barrel at least on normal firing and recoil. and means carried 2,675,087 by said wing for guiding another part of said.
  • both of said means acting to maintain the axis of the gun in a 5 substantially fixed position with respect to said wing.
  • a wing a wing frame, at least one spar in said wing frame, an automatic gun with a barrel, means carried by said spar 10 of the wing for slidably supporting the barrel of said gun, at least one preliminary stressed spring for yieldingly opposing sliding displacements of said barrel with respect to the wing,
