Definitions

  • the present invention relates to an automatic device for ejecting a container from a load, such as a sheet buoy.
  • the listening buoys generally consist of a load in which are arranged the circuits and apparatuses intended for the reception and / or the emission of signals and of a container in which are housed the members such as folded antenna, braking parachute; etc ...
  • the assembly constituted by the load and the container is released from an aircraft such as an airplane, means being provided to separate the container from the load, in order to allow the deployment of a parachute, especially.
  • the assembly thus defined also comprises means which lock or secure the container and the load during the entire storage period of handling or non-use, these locking means only having to be unlocked at the time of the release. , or immediately after dropping.
  • the object of the present invention is to propose an ejection device which is simple to produce, safe in its operation and which allows all the manipulations during the entire storage period.
  • the present invention relates to an automatic device for ejecting into the air the container of a parachuted load such as a sheet buoy
  • a container support secured to a load body a container constituted by a tube the open base of which is inserted into a housing formed in the load body and at least two symmetrical half-shells each articulated on the top of the tube
  • the device being characterized in that it comprises at least two flexible tongues each having a end connected to a point on the upper part of the lateral surface of the half-shells, while the other end is connected to an elastic bead arranged in the hollow of an external annular rib formed at the lower end of the half-shells , where an internal boss of the rib engages in a corresponding annular groove formed in the load body, the tongues having sufficient drag to move the elastic bead out of his accommodation.
  • the load release device comprises a support 1 which has the shape of a cup 2 and which can be produced either directly from the body of the load 3, or attached to the body of the charge, but made solidary of the latter by any appropriate means.
  • a tube 4 made up of one or more parts connected or not connected together ensures the function of container for the various elements associated with the load, such as a parachute, antenna, etc.
  • the tube 4 is housed by its open base in the support 1, the internal dimensions of the cup 2 and the external dimensions of the tube 4 are chosen so that there is no play between them.
  • each half-shell 6 constituting, in the folded state, a cylinder whose internal dimensions are greater than the external dimensions of the support 1.
  • the surface lateral of each half-shell 6 is greater than half of the lateral surface of the tube 4.
  • tongue end 7 On the half-shells 6 is attached a tongue end 7, the point of attachment of these tongues possibly being any point on the upper part of the lateral surface of said half-shells.
  • the tongues 7, two in number for example, are in the form of rectangular strips of length approximately equal to the height of the half-shells 6 or of the tube 4 and whose width and thickness are respectively of the order 50 mm and 0.15 mm.
  • each tongue 7 is shaped so as to allow the housing and the maintenance of an elastic member 8 in the form of a bead and intended to be placed in the hollow 9 of an outer annular rib 10 formed in the half-shells 6, the conformation of the housing 11 of the elastic member 8 being such that the latter cannot move too much in said housing 11, both in the storage state and in operation.
  • the rib 10 fits perfectly in the hollow of a corresponding rib 12 formed at the periphery of the support 1.
  • the support 1 comprises an annular groove in the form of a groove 13 in which is housed a centering and locking stud 14 provided on each of the half-shells 6.
  • the assembly is as shown in Figure 1, the pins 14 and the elastic flange 8 constituting the elastic member maintain the container on the support 1, while the tongues 7 are pressed against the half-shells. If necessary, they can be kept in this state by rolling around the tabs, and consequently around the half-shells, any adhesive tape which is torn off, for example, when boarding the means of transport from which the load must be released.
  • the drag is determined by the nature of the material used to make said tabs and by their dimensions.
  • the tongues are obtained from flexible aluminum sheets and have the dimensions mentioned above.
  • the container or tube 4 In the fully deployed state of the half-shells, the container or tube 4 is urged towards detachment from the support 1 under the action of the pressure exerted on the internal faces of said half-shells.
  • the container 4 When the container 4 is separated from the support 1, the organs which it contained are released and can fulfill their own functions.
  • the invention is not limited to the embodiment described above.
  • the container and the half-shells could be replaced by a tube in two parts hinged to each other freely, in particular by means of a flange engaging in a suitable slot so that when the bead and the flexible tongues fulfill their functions the half-parts of the container are urged towards detachment from one another, in order to allow the extraction of the organs contained in the container.
