Definitions

  • the present invention relates to an alignment system that allows pilots to adjust their position in the cockpit appropriately.
  • positions of the displays, panels and controls in the cockpit are positioned according to the eye reference point. Being determined during a design phase, this is the point where a common pilot can theoretically obtain a vision, and is defined as the midpoint of both eyes of the pilot.
  • the pilots using a helicopter will not always be the same size, the inability to bring position-sensitive equipment such as hunter helmets to this point causes the equipment to not work effectively.
  • the pilot's failure to adjust his position with respect to the eye reference point may cause the pilot to have difficulty in accessing the control panels in the cockpit, causing blind spots and false readings on some of the displays that the pilot cannot see, as well as increasing the risk of collision with the building, ground support vehicles or other air vehicles on the runway.
  • the pilots adjust the seat positions according to the eye reference points in the cockpits, making sure that their eye level and therefore their position in the cockpit are appropriate.
  • US6377401 which is included in the known-state of the art, discloses a camera on a helmet used by the pilots, and markings located in front of the camera to be detected by the camera. When the markings are in a range that can be detected by the camera, head movements of the pilot can be detected and followed by the system so as to direct the equipment. Thanks to an alignment system according to the present invention, the pilots can adjust their position in the cockpit correctly.
  • Another object of the present invention is to detect head movements of the pilots precisely and accurately, so that the helmets used by the pilots operate simultaneously and error-free with the systems such as weapon and camera systems on the air vehicle.

  • the alignment system of the invention comprises a bracket which extends outward from the body; the guide located on the bracket as an opening; and the reference position in which the guide and the indicator are aligned completely on top of each other with respect to the pilot's angle of vision, thus enabling the pilot to reach a predetermined position in the cockpit.
  • the alignment system comprises at least one helmet which enables the pilot to control the systems on the air vehicle, or reflects the images transmitted from the cameras provided on the air vehicle; at least one sensor system which detects the head movements of the pilot during flight so as to provide data to the camera and weapon systems on the air vehicle, wherein the sensor system is operated while the pilot's eye is in the reference position, thus enabling the pilot's head movements to be detected more accurately and smoothly.
  • the alignment system comprises a first indicator and a second indicator which are located on the body; a first guide located on the bracket when the pilot is in the reference position, and overlapping the first indicator when the pilot closes his/her right eye and looks with his/her left eye; a second guide located on the bracket and coinciding with the second indicator when the pilot closes his/her left eye and looks with his/her right eye.
  • the alignment system comprises the first indicator and the second indicator which, in air vehicles steered by two pilots, allow both pilots to adjust their position in the cockpit using only a single bracket, wherein the first indicator and the second are used by the first pilot when the pilots are in the reference position; a third indicator which is aligned in an overlapping manner with the first guide used by the second pilot; and a fourth indicator aligned with the second guide in an overlapping manner.
  • the alignment system comprises the bracket which is produced integrally with the body.
  • the alignment system comprises the bracket located on the body in a removable way.
  • the alignment system comprises at least one canopy which protects the panels in the cockpit from sunlight and reflections; the bracket located on the canopy and extending outward from the canopy; and the indicator which is located on the panel.

  • the alignment system comprises the indicator which can have polygonal forms such as triangle, quadrilateral, pentagon.
  • the alignment system comprises the indicator whose wall and center are of different colors, thus allowing the pilot to determine the reference position more accurately.
  • the alignment system comprises at least one marking located on the bracket, which indicates the areas that the indicator in a polygonal form, such as a triangle or rectangle, should overlap with the guide when the pilot is at the reference position, thus allowing the pilot to find the reference position more easily and accurately according to the vertices of the polygon.
  • the alignment system comprises the guide, the indicator and the reference position, which are used on attack helicopters or civilian helicopters.
  • the alignment system comprises the sensor system which detects the head movements of the pilot so as to send commands to the camera and weapon systems, thus allowing the camera and weapon systems to be dependent on head movements of the pilot.
  • the alignment system comprises an air vehicle which is either a plane, civil, or attack helicopter.

  • the pilot can determine the position where the indicator (3) and the guide (4) coincide, in a more precise and accurate manner.
  • the pilot can access the flight controls and system control panels in the cockpit, and the displays in the cockpit to be almost completely visible to the pilot.
  • an alignment system (1) comprises at least one helmet (7) used by the pilot; at least one sensor system (8) which detects position and movements of the helmet (7) in the cockpit according to the head movements of the pilot, thereby sending commands to the systems in the air vehicle and providing input to the systems; the reference position (5) which enables position and movements of the helmet (7) to be detected by actuating the sensor system (8) while the pilot's eye is in the position where the guide (4) almost visually coincides with the indicator (3).
  • the helmet (7) used by the pilot comes to a predetermined point in the cockpit.
  • the reference point (5) the pilots of different heights or sitting in different positions sit in the cockpit in a predetermined position while using the air vehicle, so that the position sensitive helmet (7) and the sensor system (8) operate more effectively ( Figure - 2).
