Definitions

  • This invention relates to a mechanism that provides to move the covers closing the areas where payloads are located in air vehicles.
  • Payloads such as ammunition, fuel tanks, electronic warfare devices, landing gears, cameras are generally transported by mounting them in various areas on air vehicles. These areas on air vehicles should be closed with covers and opened when necessary. Especially in new generation air vehicles, low visibility, transonic and supersonic stability and structural and aerodynamic optimization of geometry gain importance. An unstable and highly complex flow occurs when a door is opened even when the respective air vehicle is flying at a constant altitude. In addition, a decrease in stability in the covers, which are also affected by side forces, potentially poses a danger.
  • each door is formed of an outer half and an inner half pivoted together at hinge. The outward edge of the outer half is hinged at hinge link assembly to bracket fixed on the aircraft structure.
  • a first double-acting cylinder is mounted between the fixed aircraft structure and the inner end of the outer half.
  • a second double-acting cylinder is secured between the aircraft structure and the inner half.
  • a further object of the present invention is to provide ease of operation during maintenance etc. by increasing the height between the cover and the ground in the open position of the cover.
  • the cover movement mechanism realized to achieve the object of the invention, defined in the first claim and in the claims dependent thereon, comprises a part and/or the body of an air vehicle.
  • a payload is placed in a chamber-like opening on the body.
  • a triggering arm in the form of a tube can be rotated around an axis on which it extends.
  • the cover which is a part of the aerodynamic surface of the aircraft, the payload can be prevented from being exposed to the air flow.
  • the geared actuator located on the triggering arm the rotational motion can be transmitted to the cover so that the cover can be triggered.
  • At least one support element is connected to the cover with one end thereof being connected to the cover and the other end thereof to the body by means of a movable joint.
  • the cover movement mechanism comprises a connection element, with one end thereof being connected to the gearbox by means of a fixed joint, and the other end thereof being connected to the cover by means of a movable joint.
  • the point where the connection element is connected to the cover is selected so that this point stays between the point where the support element is connected and the gearbox.
  • the connection element triggers the cover to move between the open position (A) and the closed position (K) by means of the movement transmitted from the gearbox.
  • the connection element may be provided in plurality, but they are all on an axis parallel to the triggering arm, i.e. in the same direction. Thus, by virtue of the support element and the connection element connected to the cover from different points, the cover is moved in parallel planes while moving between the open position (A) and the closed position (k).
  • the cover comprised by the cover movement mechanism does not make a planar angle while moving between the open position (A) and the closed position (K).
  • An auxiliary part is comprised that is hinged to the cover and rotates around the point where it is hinged to the cover while the cover is moved between the open position (A) and the closed position (K).
  • the auxiliary part rotates towards the opening.
  • the angle towards the opening between the cover and the auxiliary part is reduced.
  • the auxiliary part rotates and closes the opening.
  • the angle towards the opening between the cover and the auxiliary part increases and comes to the same plane when closed.
  • the auxiliary part comprised by the cover movement mechanism is attached to an edge of the cover that is close to the triggering arm.
  • the auxiliary part and the cover can almost completely prevent the air flow from reaching the ammunition.
  • the auxiliary part and the cover are in the closed position (K).
  • the connection element connected to the gearbox pushes the cover so as to cause it to be opened.
  • the auxiliary part is rotated around the point where it is connected to the cover and at the same time, is also pushed by a connecting rod. In this case, the auxiliary part and the cover are in the open position (A).
  • connection rod keeps the auxiliary part
  • the auxiliary part supports the cover from its edge, and that the connection element is connected to the cover from between the support element and the auxiliary part, it is ensured that the cover moves along planes which are parallel to each other between the open position (A) and the closed position (K) in a way that the planes do not intersect each other at any angle.
  • connection element comprised by the cover moving mechanism pushes the cover while the cover and auxiliary cover are brought from the closed position (K) to the open position (A) by means of an actuator.
  • the connection element rotates with the gearbox and pushes the cover, the auxiliary part is likewise pushed by the connection rod and opened.
  • connection element comprised by the cover movement mechanism pulls the cover while the cover and auxiliary cover are brought from the open position (A) to the closed position (K) by means of the actuator.
  • the connection element rotates with the gearbox and pulls the cover, the auxiliary part is likewise pulled by the connection rod and opened.
  • the side of the connection element, comprised by the cover movement mechanism, that is close to the gearbox has a curved form and therefore its full form is called a gooseneck.
  • connection element comprised by the cover movement mechanism has a channel-shaped groove preferably along its whole length, thereby enabling the connection rod to be connected to the walls of the groove.
  • the form of the connection element facilitates the assembly of the connection rod and prevents the connection rod from hitting the connection element when the cover and the auxiliary part are in the open position (A).
  • the support element has a straight bar form that is connected to both sides of the cover and the connection rods are connected to each connection element in the cover movement mechanism.
  • connection rod comprised by the cover movement mechanism is mounted to the connection element and onto the auxiliary part by means of a movable joint.
  • connection element comprised by the cover movement mechanism is fixedly connected onto the gearbox by means of two pins.
  • the actuator is in the form of a hydraulic actuator
  • the trigger arm is in the form of a torque tube that is rotated by the actuator in a clockwise and counterclockwise direction so as to enable the cover and the auxiliary part between the open position (A) and the closed position (K), wherein the gearbox enables the movement of the triggering arm to be directly transmitted to the cover and indirectly to the auxiliary part in the cover movement mechanism.
  • the payload placed in the opening that is in the form an ammunition receptacle is ammunition in the cover movement mechanism.
  • the cover movement mechanism comprises hinges at an edge between the cover and the auxiliary part so that they can be rotated and folded relative to each other.
  • Figure 1 is a schematic representation of an air vehicle.
  • Figure 2 is a schematic representation of a payload, an opening and body.
