Definitions

  • the invention relates to an aiming head equipping an aircraft such as a rotorcraft. More specifically, the subject of the invention is a sighting head equipped with an integrated laser pointer allowing the illumination of a target by a laser beam emitting radiation in the visible or near infrared.
  • the invention applies in particular to a head of sighting of a helicopter fire control.
  • the aiming head comprises a most of which is generally located above the roof of the helicopter's cell.
  • a eyepiece arm extends the aiming head to inside the cell.
  • a beam laser Under certain conditions of use, it is necessary to illuminate the target with a beam laser. Depending on whether the user observes the target by eye naked or using night vision goggles, uses a laser beam emitting in the field visible or in the near infrared domain.
  • laser pointer a device that provides target illumination. More specifically, this device is held by hand, outside the helicopter. Indeed, the cell of the helicopter would significantly reduce laser frequencies and would cause reflections harmful internal if the laser pointer was used inside the helicopter.
  • Document FR-A-2 640 037 relates to a viewfinder helicopter mast equipped with a rangefinder or laser light barrier, which looks through the rotor blades. This arrangement makes it possible to take into counts the moment the rotor blade passes during the alignment process between the viewfinder and the system missile seeker.
  • the subject of the invention is precisely a head sight equipped with an integrated laser pointer allowing ensure pointing accuracy and range of optimal use, without degrading the specific characteristics of the aiming head.
  • the invention relates an aiming head for rotorcraft, comprising a housing at least part of which is suitable for being located the exterior of a rotorcraft cell, characterized by that a laser pointer is integrated into the aiming head, in said part of the housing.
  • the part of the housing located at the outside of the cell is bounded towards the outside of the sighting head by a cowling existing aerodynamics thereof. So the aerodynamic behavior of the aiming head is not modified by the integration of the laser pointer.
  • the laser pointer comprises a laser transmitter and orientation adjustment means of it in said part of the housing, allowing to render a laser beam emitted by the laser pointer parallel to an aiming axis of the aiming head. It is thus possible to precisely adjust the parallelism of the laser beam and the axis of the aiming head.
  • the adjusting means preferably include three screws setting regularly distributed around the transmitter laser.
  • the laser pointer includes plus a clean power source for the laser transmitter and a radio receiver allowing the ignition and switching off the laser transmitter.
  • FIG 1 there is shown schematically the front part of a helicopter. This includes a cell 10 whose roof supports a sighting head 12 of a firing line (not shown).
  • the sighting head 12 comprises a housing 14 of which a main part 16 is situated above the roof of cell 10, outside the helicopter. Another part 18 of the housing 14 is located at inside the cockpit 20 of the helicopter. An eyepiece arm 22 terminated by a eyepiece 24 is mounted on the part 18 of the housing 14, to allow an observer placed in cabin 20 to use the aiming head 12.
  • Parts 16 and 18 of the housing 14 and the arm eyepiece holder 22 are used to house different components optics (not shown) allowing an observer looking through eyepiece 24 to observe a scene according to a line of sight 26. Only an exit lens 28, arranged along this axis 26, is visible in FIG. 2.
  • the main part 16 of the housing 14 allows also to house a camera 30.
  • a laser pointer 32 is also placed inside the part main 16 of the housing 14.
  • the laser pointer 32 is housed in an area of the main part 16 of the housing 14, bounded towards the outside of the aiming head 12 by an existing aerodynamic cover 34.
  • the area in which is housed the laser pointer 32 is located above the camera 30.
  • this area can be located in any other available location suitable, according to the characteristics of the head of sight in which its implantation is carried out.
  • the area in which is received the laser pointer 32 is chosen taking into account of a number of criteria such as comfort of use for the operator, the existence of a volume sufficient to allow the establishment of different organs making up the laser pointer, the existence of hanging possibilities guaranteeing good rigidity, ease of access for maintenance and respect of the outside geometry of the aiming head.
  • the laser pointer 32 essentially comprises a laser transmitter 36, an energy source 38 suitable for this transmitter and a radio receiver 40.
  • the laser transmitter 36 is, for example, a laser emitting diode capable of emitting a laser beam in the visible or near domain infrared, depending on whether the observer watches the scene from with the naked eye or with night vision goggles.
  • the laser transmitter 36 is mounted on a support 42, fixed inside part 16 of the housing 14, for example by means of screws 43. More precisely, the laser transmitter 36 is mounted on the support 42 by means of adjustment 44 orientation. Said adjustment means 44 have the function of allowing adjustment precise parallelism of the laser beam likely to be emitted by the laser transmitter 36 with respect to the axis sight 26 of the sight head 12.
  • the means 44 of orientation adjustment include three adjustment screws 46, oriented parallel to the axis of the laser transmitter 36 and regularly distributed around this axis.
  • a front part of the laser transmitter 36 is fixed to a plate 48, at the front of the support 42, and it passes through an opening 49 machined in said support.
  • the screws 46 freely pass through holes 50 and 52 formed respectively in the support 42 and in the plate 48, and they are screwed into nuts 54, at the front of plate 48.
  • Coil springs of compression 56 mounted on each of the screws 46 between the support 42 and plate 48, permanently maintain these two rooms distant from each other.
  • the front end of the transmitter laser 36 is located opposite an opening 58 formed in said cowling and each of the bolts 54 is located opposite a hole 60 drilled in the cowling 34.
  • the energy source 38 is, for example, a battery or power supply battery. She is placed under an opening in the cowling 34, normally closed by a hatch 62. The source of energy 38 has the function of supplying energy the laser transmitter 36 and the radio receiver 40.
  • the radio receiver 40 is connected electrically to the laser transmitter 36 and to the source of energy 38 to allow switching on and off of the laser transmitter 36.
  • the invention is not limited to embodiment which has just been described as example.
  • the laser pointer can be installed on an aiming head of different design and in a different location of the one which has been described, without going beyond the framework of the invention.
