Definitions

  • the invention relates to a device for coupling and then separating airborne projectiles according to the preamble of claim 1. It also relates to projectiles equipped with such devices.
  • the invention relates to such a coupling device capable of simultaneously ensuring the hooking and chocking functions of a plurality of projectiles, with a view to carrying them under aircraft, as well as their ejection one by one, starting by the one which is furthest from this aircraft.
  • One means of carrying multiple loads under an aircraft consists in attaching an intermediate part, generally called an "adapter", to a polyone, integral with the aircraft, which has a plurality of hooking locations for the loads to be transported. At each of these locations, there are installed the devices allowing, the attachment, the setting, the safety controls, and the ejection of the load.
  • a load ejection system is generally installed in the adapter to eject the load downwards at a determined speed.
  • chocking generally using chock screws carried by arms
  • the ejector usually pyrotechnic, is included in the adapter at each location.
  • the device described comprises a hooking means which comprises, diametrically opposite, a male part in the form of a cylinder which carries balls regularly spaced at its periphery and a female part constituted by a fixed base comprising a rim which provides a continuous circular groove intended for the embedding of the balls of the male part of the adjacent projectile.
  • a first drawback of this attachment means results from the need for precise manufacture of the elements to jointly ensure the mutual attachment and wedging of the projectiles; a second drawback lies in the relative complexity of producing the male part which further comprises a movable collar for retaining the balls.
  • the present invention aims to overcome the aforementioned drawbacks and aims to provide a coupling and separation device comprising a combination of means which cooperate with each other to accomplish the following four essential functions, namely: the attachment of a load one under the other, the mutual mechanical setting of each of these charges thus attached, the electrical connections between the carrier vehicle and the various electrical members of the projectiles and, the sequential separation of these charges thus superimposed, starting with the charge farther from the adapter fixed under the carrier vehicle or aircraft.
  • the object of the invention is a device for coupling and then sequentially separating a plurality of all identical projectiles carried by an aircraft, this device comprising a hooking means which comprises diametrically opposite, a male part, movable in rotation around its axis, which carries regularly spaced balls at its periphery and a female part constituted by a fixed base in which a cavity is delimited by a rim interrupted by cells intended for the engagement of the balls of the male part of the underlying projectile, the ball-bearing cylinder comprising a rotational drive means which cooperates with first and second fixed supports located on the directly adjacent projectile to provide a means for mutual setting of the projectiles.
  • the ball-bearing cylinder comprises a movable concentric piston, the axial movement of which allows the radial movement of the balls and consequently the separation of the projectiles.
  • the male and female parts of the attachment means respectively comprise electrical contacts and retractable conductive pads to ensure the electrical connections between the aircraft and various electrical members placed in the projectiles.
  • FIGS. 2a and 2b each represent a detail of FIG. 1.
  • the first and the second bomb 1 and 2 are respectively called carrier bomb of rank (n - 1) and bomb carried of rank (n).
  • the number (n) depends on the resistance criteria of the materials and the mechanical stresses involved. Only part of these bombs is represented with the exception of the front part (Av) and the rear part (Ar).
  • the coupling device according to the invention is generally referenced 20.
  • It essentially comprises a combination of mechanical attachment and setting means, electrical means for transferring the control signals, and ejection means. It is an integral part of the body of the load (in the example described). But they can be independent and is then connected to it solidly by any means which does not compromise the aerodynamic qualities of the assembly. In all cases, it is positioned near the center of gravity of the load.
  • the hooking and wedging means essentially comprise a connecting element 70 connecting together a male part 3 and a female part 6.
  • the first part in an exemplary embodiment comprises a pivotable cylinder 4 carrying balls 5 and a system of rather conductive 83 ( Figure 2b) whose function will be described later.
  • the second part 6, known as the fixed base comprises, as shown in FIG. 2a, a cavity 7 delimited by a flange 8 interrupted by cells 9. It also includes a set of mobile pads which are good conductors of electricity intended to cooperate, as will be explained below, with the fixed studs 83 of the pivotable cylinder.
  • the number and the arrangement of the balls 5 at the periphery of the attachment cylinder 4 on the one hand, the distribution of the cells 9 in the cavity 7 on the other hand, are such that at first the attachment cylinder of the bomb carried having rotated by a certain angle, can be introduced inside the cavity 7 of the bomb 2 carried, the balls then coinciding with the cells 9 along which they can slide and in a second time, the cylinder 4 ball holder 5 having returned to its initial position, the balls 5 are supported by the rim 8 of the cavity 7 then playing a support role for the balls 5.
  • the attachment between the carrier bomb 1 and the carrier bomb 2 is thus assured.
  • First means 10 are provided for rotation of the attachment cylinder 4, ball holder 5, while second means 11 ensure the displacement of wedging wedges 12 intended to cooperate with the oblique surfaces of a support 13.
  • the bomb carried is then wedged in three directions, thanks to the combined action of the connection by the attachment cylinder, wedging wedges and first supports 13 and second fixed supports 15 whose shape substantially matches that of the body the bomb.
  • a housing 90 formed in a bracket 111 is provided for receiving a key whose rotation will cause that of the cylinder 4 ball holder 5.
  • Figures 3 and 4 schematically show, in section and from above the means 10 and 11 intended respectively to ensure the movement of the attachment cylinder 4 carrying the balls 5 and that of the wedging wedges 12. These means are shown in these figures in the configuration corresponding to the so-called rest state, that is to say that which corresponds to the storage of the bombs before hanging for the purpose of carrying.
  • the carrying bomb 1 on which a first carried bomb 2 will be hung is equipped with a device according to the invention.
  • a slide called upper slide referenced 21 on which can act the key inserted in the housing 90 and a plate or slide referenced 22 connected integrally to the cylinder hooking 4 and causing it to rotate.
  • a finger 23 coordinates the movements of the upper slide 21 and of the slide 22 and is integral with a second slide called the lower slide referenced 24 attached to the casing 25 by means of studs 26 and 260 allowing its sliding between the casing and the head of these studs.
  • This slider 24 includes a light 27 which allows the slider 24 to slide at the level of the central stud 260 ( Figure 3) all along the light 27.
  • This slider 24 is also made integral with the two wedging wedges 12 which will follow its movement but which are returned to the initial so-called rest position by means of a return spring 29.
  • the device according to the invention is an integral part of the bomb, that is to say that the envelope 25 is confused with the shell (or body) of the bomb, but as has already been said, such a device can be produced in the form of an independent part.
  • the slide 21 and the slide 22 have each a guide path (a slit) 31 and 32 for the finger 23. They have the same profile which in the rest state does not however overlap. Thus, the finger 23 is flush with the guide path 31 of the slide 21.
  • the profile of this guide path 31 in plan view is not shown but it is the same as the profile of the guide path 32 of the second slide which is shown in Figure 4.
  • This Figure 4 has been shown, seen from above, in a configuration where the upper slide 21 has been removed, this to facilitate description and understanding.
  • the slide 22 has a second longitudinal guide path 33.
  • the slide 21 and the slide 22 are held together by lugs 330 allowing relative movement in two parallel planes of one and on the other of these parts 21 and 22.
  • the attachment of the first carrying bomb 1 with the second carried bomb 2 is achieved in particular thanks to the cooperation of this slide and this slide whose movement is ensured by the finger 23 like this is now described and illustrated by means of FIGS. 5 and 6.
  • Figure 5 shows, in sectional view, the position of the various elements constituting the attachment and timing system itself, namely the slide and the slide 21 and 22, the finger 23 guided by the guide tracks 31, 32 , 33.
  • the springs 29 and the wedging wedges 12, these elements being driven in movement by means of the key 102, when the key is in a position such that the finger 23 is unlocked.
  • Figure 6 is a plan view of the same attachment and wedging system in an intermediate configuration according to the unlocking configuration and before locking, shown in the previous figure, during which the finger 23 guided in the curved guide paths 31 and 32 then placed in coincidence, rotates the slide 22 and the cylinder 4 which is integral with it.
  • the key 100 which includes a control lever 101 and a bolt 102 capable of applying a force on the upper slide 21 on a curved part of the latter called, striker 103 by analogy with the bolt 102.
  • striker 103 As and as the operator presses the bolt 102 of the key 100 on the keeper 103 of the upper slide 21 in the direction of the arrow 104 (FIG. 5), the set of upper and lower slides 21 and 24 moves in the direction of the arrow 105.
  • the finger 23 first guided by the longitudinal guide path 33 driving the lower slide 24 until the guide path 32 coincides with the guide path 31 of the upper slide 21, paths whose profiles are l both identical and curved as mentioned above.
  • FIG. 6 schematically represents an intermediate configuration clearly showing the angle a already existing between the longitudinal axis AB of the device and the longitudinal axis A'B 'of the upper slide and slide system.
  • the receding wedging wedges are applied to the support 13, thus ensuring the wedging of the carried bomb maintained, moreover, both by the attachment system and the fixed support with curved contact 15. It is immobilized in all directions without the need for more or less sophisticated timing adjustments.
  • FIG. 7a the upper slide and the slide occupy a position corresponding to the configuration shown in FIG. 1.
  • the key 100 is inserted into the housing 90 provided for this purpose.
  • the upper slide 21 and more particularly the keeper 103 of this slide on which the bolt 102 of the key 100 must come to bear is extended by a spout 110
  • the key can be inserted or removed without difficulty , the housing 90 not being obscured by this spout 110.
  • FIG. 7b when the key has accomplished its function, that is to say when it has brought the slide and the slide 21 and 22 in the position shown in particular in FIGS.
  • the operator can in no case remove the key: in fact, the housing 90 is partially obscured by the spout 110. So he must either continue the maneuver or go back. Under these conditions, it is easy to monitor the correct locking of all the bombs attached to each other by means of the device according to the invention. It suffices to note that no key remains after assembly and if there remains a forgotten one by mistake, to verify that it is possible to remove it and therefore to perform this action.
  • such a device also comprises a connecting element (reference 70 in FIG. 1) between the cylinder 4 with ball bearing and the cavity 7, an element containing the electrical transfer members on the one hand and the ejection means on the other hand.
  • FIG. 8 schematically illustrates an exemplary embodiment of such a connecting element 70.
  • the two charges in the example describing the bomb 1 carrier and the bomb 2 carried, are shown.
  • Any female part 6 referenced 6a in the case of the bomb 1 and 6b in the case of the bomb 2 comprises a plurality of movable pluts 82a and 82b. In the example described, there are four of them distributed uniformly over a ring 85a and 85b, two of which are only visible in FIG. 9.
  • Fixed contact pads 83b (the fixed pads belonging to the bomb 1 do not appear on Figure 8) in the same number as the movable contact pads 82a are provided and distributed in the same way on a ring belonging to the cylinder 4 ball holder.
  • the arrangement of these movable pads and these fixed pads are such that they cooperate with each other to ensure, when they are applied respectively against each other, good electrical contact.
  • the crown 85a belongs to the cavity 6a of the carrier bomb 1 and the movable studs 82a (symbolized by the presence of the springs 850 come to bear on the fixed contacts 83b of the ball-bearing cylinder 5 of the bomb being carried 2
  • the connecting element 70 also includes a sequencer 159 which receives the electrical orders emitted by the pilot of the aircraft and leading to the adapter attached to the pylon of this aircraft The orders pass as follows, illustrated diagrammatically by means of FIGS. 9a and 9b.
  • the sequencer 157 is off and therefore receives no pulse in this sequence. As a result, only the sequencer 159 will be activated and able to deliver the control signals ensuring the smooth running of the rest of the programmed operations. In the case where only one bomb is still attached, the contact 160 is on the contrary in the closed position and this signal is therefore applied to the sequencer 157 which can thus play its role. In the example described as mentioned above, there are four fixed and movable studs. Three of these pads are used to control the sequencers and the fourth to trigger a pyrotechnic charge 170 as shown in FIG. 8.
  • the electrical transfer circuit intended to control the firing of this pyrotechnic charge 170 follows the same process as that which has just been described for the various sequencers: namely that only the pyrotechnic charge of the lowest bomb (bomb of rank n) is ignited; the rant bomb (n - 1) can only be ignited when the row bomb (n) has itself been ejected.
  • the firing of a pyrotechnic charge for example the charge 170 of FIG.
  • the invention applies in particular to weapons systems requiring the successive dropping of a large number of military charges such as bombs or various projectiles.
