Definitions

  • the invention relates to a safety device for dropping a load intended to be suspended from an aircraft for its transport. It also relates to any load equipped with such a device.
  • a device for dropping a load suspended from an aircraft which comprises: on the one hand, hooking rings which cooperate with hooks carried by the aircraft and, on the other hand, a plate sliding with respect to the suspended load, this plate comprising openings intended for the passage of armament cables which are connected to a pair of rockets.
  • the sliding bar can be moved under the action of a spring, between a first position called “safety” and a second position called “armed”; this movement being subject to complete disengagement of the hooks in the attachment rings.
  • the device comprises cables for cocking the rockets of the load and these cables are provided with traction rings mechanically connected to the aircraft.
  • the present invention relates to a release safety device comprising a sliding plate, called a "bus bar", of the type described above; this busbar comprises two obstructing members: a first obstructing member mechanically connected by a traction cable to the aircraft and a second obstructing member mechanically connected to the load hooking ring under the aircraft carrier and this bus bar comprising a set of locks, each of these locks having different sections to allow its locking in the bar and its unlocking from the bar.
  • Figure 1 In Figure 1 are shown locks 1, 2, 3 (by way of example three in number) and the control means associated therewith 4, 5, 6 intended to ensure their unlocking, thereby releasing the member or members contained in a container (not shown in the figure) that they locked.
  • It can be military charges, elementary tanks, modules, intended to be released together or successively, that is to say on demand. All of these organs and their control accessories are attached to the carrier vehicle (not shown) by means of a hanging system.
  • It is for example at least one ring 7, integral with the body containing the elementary modules, into the lumen 80 from which the hook of the carrying means (not visible in the figure), itself integral with the carrier vehicle, penetrates. The separation takes place when the hook is deliberately detached from the ring, thereby releasing the ring-hook connection.
  • a device 10 having the character of a general mechanical control member, is provided.
  • This bus bar 10 can occupy two positions: the first so-called “safety” position (the one shown in the figure) and a second position called the “armed” position.
  • the displacement of this bar can be controlled by any known means.
  • a cable 11 which may be a safety cable releasable from an SLC base, is stressed in tension at one of its ends 12.
  • a set of pulleys 13, 14 and 15 and of the spring 16 it acts on the spring 17 which compresses against the stop 18, thereby releasing a movable locking finger 19 which retracts.
  • the bus bar 10 previously held in its safety position by this finger 19 is released and, under the action of the return spring 20, moves back, translates in a given direction (for example that of the arrow 21) towards its position called “army”.
  • Housing 25, 26 and 27 are provided in this bus bar.
  • a combination bus bar lock is described below as an example.
  • These housings intended to cooperate with the locks comprise two parts: a first open cavity having a profile with a substantially circular section of diameter D and a second open cavity having a profile with a substantially rectangular section of width D, much less than D.
  • the locks in the example described, comprise for example two parts: the first, of cylindrical section, with a diameter very slightly less than D can move in the first cavity and ultimately be unlocked; the second has a thinned section over a length L slightly greater than the thickness of the bus bar and can only move in the second cavity over a short stroke corresponding approximately to this length L.
  • the locks In the safety position (cell in the figure) the locks, even if they receive the unlocking order, are locked, and the operation cannot take place.
  • the busbar 10 When the busbar 10 is in its so-called "armed" position, these same locks are positioned in the second cavity 25b, 26b, 27b of the housings and are then in the unlockable position and ready to undergo the action of the unlocking means 4, 5, 6 to retract as shown respectively by the arrows 30, 31, 32.
  • the unlocking orders depend on the sequence of operations chosen, either simultaneous or offset.
  • the busbar by moving from its "safety” position to its "armed” position, the busbar pushes through an additional housing 350 on a stud 35 which drives in rotation (see the direction arrow 36) the ring 7. If this ring 7 is still connected to the hook of the carrier vehicle, the hook-ring connection opposes this rotation and therefore opposes the movement of the bus bar 10 from its position "security” to its “armed” position. Consequently it is necessary that the separation of the ring from the hook of the carrier vehicle is effective for this movement to take place and for the unlocking of the locks 1, 2 and 3 to be possible. It is an extremely reliable security system which constitutes one of the main characteristics of the invention.
  • FIG. 2 is a schematic representation of an alternative embodiment of the combination of a bus bar 10 and a ring 7 cooperating in order to obtain the result stated above, namely the possible movement of the bus bar exclusively in the case where the hook of the carrier vehicle is well separated from the ring.
  • the ring 7 with its thread 70 intended to fix it to the container which must be transported and then released.
  • This ring 7 is connected, in this variant, to the bus bar 10 of the type which was described in the previous variant in the manner described below.
  • the first end of a lever arm or pallet 50 penetrates into the lumen 80 of the ring 7. This arm is articulated around a hinge pin 51.
  • FIG 3 is a schematic representation of another alternative embodiment of a combination according to the invention.
  • the ring does not rotate as in the case of Figure 1, but it rocks. Indeed it is held in place during the entire transport phase thanks to a lug 60 which takes place in a housing 61, provided for this purpose and formed in the bus bar 10 hampering the movement thereof.
  • This lug 60 leans upwards during transport against the structure of the container (not shown). It is held there as long as the hook of the carrier vehicle, by its presence inside the ring prevents a torsion spring 62 from playing its role.
  • FIG. 4 schematically represents an alternative embodiment in which the movement of the ring is vertical.
  • the ring 7 comprises, in addition to the lumen 80 intended to receive the hook of the carrier vehicle, a first cylindrical part 81 comprising a shoulder 82.
  • This cylindrical part 81 is contained in a housing 83 formed in the envelope 84 of the container which must support the ring, a spring 85 is provided between this shoulder 82 and one of the walls 86 of the housing 83.
  • the ring also comprises a second part 87 intended to penetrate into the bus bar 10. This second cylindrical part comprises a portion 90 thinned over a determined length. When the ring is suspended from the carrier hook, the spring 85 is compressed and the cylindrical part 87 is located in the circular section cavity 91 formed for this purpose in the bus bar 10.
