DESCRIPTION
MULTI-FUNCTIONAL MISSION GRIP SYSTEM FOR A VEHICLE Field of the Invention
The present invention relates to a mission grip system which enables to control moving digital map system, weapon system and target detection/sighting system equipment by means of a copilot right hand mission grip, copilot left hand mission grip, pilot mission grip and control units integrated into aircrafts (e.g. T-129 Atak (Attack) helicopter).
Background of the Invention In the state of the art applications, the interfaces between the user and the moving digital map system, weapon system and target detection/sighting system can be provided by limited means, and time consuming methods that are difficult to be accessed. The number of the systems controlled by the mission grips used in aircrafts is limited and/or they are more inconvenient. This in turn increases the user' s time loss and error rate.
Again in these applications, non-ergonomic designs made for the users cause the user to get tired and fail performing necessary functions as required, and the system to occupy a more than necessary space in the cockpit in long duration flights. Furthermore, failure to read the labels on the mission grips in night flights brings along possible problems.
Problems Solved by the Invention The objective of the present invention is to provide a mission grip system which enables the user to control different systems simultaneously in aircrafts. Thanks to
the present invention, a more convenient accessibility is provided between the pilots and the moving digital map system, weapon system and target detection/sighting system, and by the support of more user interfaces, the pilots are enabled to save time and the error rate is reduced.
Another objective of the present invention is to provide a mission grip system which, in addition to providing ease of use in short and long duration flights of the users by means of its ergonomic design architecture, provides advantage of space for the other equipment in the cockpit owing to the fact that it occupies a smaller space in the cockpit.
By means of the illumination panels provided on the front side of the mission grips, the labels indicating the key functions can be read in night flights and the said mission equipment are enabled to be used more effectively in night conditions compared to the past.
The mission grip system of the present invention is developed in compliance with the environmental requirements determined by military standards (MIL-HDBK- 5400, MIL-STD-810, MIL-STD-704 and MIL-STD-461). Within this framework, altitude, low and high temperature, thermal shock, humidity, vibration, mechanical shock, dust, salty atmosphere, rain, acceleration, solar radiation, temperature-altitude, temperature-vibration, power and EMI/EMC tests are applied to the equipment.

15. Control unit A mission grip system (1) which enables the pilot/copilot to control the critical mission equipment in aircrafts simultaneously, basically comprises
at least one pilot mission grip (2),
at least one copilot left hand mission grip (3) and/or at least one copilot right hand mission grip (4),
at least one fire trigger (5) which enables to fire the gun, missile and/or laser located in the aircraft,
at least one button guard (6) which prevents accidental pressing of the fire trigger (5) by covering the said trigger,
at least one sunk button (7) which is assigned for critical missions and which is sunk in at least one of the mission grips,
at least one first protrusion (8) which is provided on at least one of the mission grips and which prevents slipping of the user's hand from the mission grip by providing a friction between the hand and the handle, at least one second protrusion (9) which is provided at the base of at least one of the mission grips and which contacts the bottom of the hand and extends outwards preferably parallel to the ground plane for preventing the hand from slipping downwards,
at least one gun interface unit (10), which is adapted to generate control signals according to the discrete control and condition signals coming from the mission grips for controlling and firing the gun units in the aircraft and to transmit these signals to the gun unit that will be controlled; and to generate location information from the data coming from the gun unit location sensors and to transmit these information to the gun unit that will be directed,
at least one weapon interface unit (11) which is adapted to generate the power and discrete signals required to fire the laser guided missiles, unguided missiles, air-to-air missiles and/or antitank missiles which are integrated to the aircraft,
at least one mission computer (12) which is adapted to control all mission equipment such as moving digital map system, weapon system and target detection/sighting system of the aircraft and to provide the data transmission between the said equipment,
control levers (collective & cyclic) (13) which enable to perform the basic flight controls,
at least one power supply (14) which supplies the required energy, at least one control unit (15) which is adapted to generate the power signals required for the mission grips, and to collect the parallel data coming from the mission grips and to transmit the said data serially to the mission computer (12).
A preferred embodiment of the mission grip system (1) of the present invention includes a pilot mission grip (2), copilot left hand mission grip (3) and/or copilot right hand mission grip (4). Each mission grip has a button guard (6) on the gun, missile and/or laser fire trigger (5), and thus accidental pressing of the fire trigger (5) (preferably the button that corresponds to the index finger) by the pilot/copilot is prevented (Figure 3, 4 and 5).
In one embodiment of the invention, the said button guard (6) is located at the rear part of the handle on the mission grips such that it is connected to a shaft and can rotate around the axis of the said shaft (Figure 3, 4). In another embodiment of the invention, the button guard (6) is positioned such that it covers at least one of the buttons provided on the upper part of the handle and that it rotates around the axis of a shaft (Figure 5). When the fire trigger (5) is intended to be pressed, the button guard (6) is lifted upwards to access the fire trigger (5).
In one embodiment of the invention, there is provided at least one sunk button (7) which is assigned for performance of critical missions and which is arranged as sunk in the body of at least one of the mission grips (Figure 6).
In one embodiment of the invention, the handle parts of the body are produced in an ergonomic form in order to prevent the hand from slipping on the mission grips and getting tired. As can be seen in Figure 7, there is a plurality of first protrusions (8) on the said handle. These first protrusions (8) enable a friction
between the hand and the handle, and this way the user's hand is prevented from slipping from the mission grip.
In one embodiment of the invention, there are illumination panels, which are compatible with night vision goggles used in aviation, provided on the front surface of at least one of the mission grips. Thus, the labels, which are provided on the front part of the mission grips, and which indicate the key functions can be seen more easily in night flights, and the pilots are enabled to use the weapon systems more easily and effectively in night flights.
In one embodiment of the invention, there is a second protrusion (9) which is provided on the base of at least one of the mission grips and which extends forward or sideward preferably parallel to the ground plane (Figure 7). The said second protrusion (9) contacts the bottom part of the hand and prevents the hand from slipping downwards from the handle and thus prevents the user from losing control of the mission grip.
In a preferred embodiment of the invention, the discrete signals coming from the pilot mission grip (2), copilot left hand mission grip (3) and copilot right hand mission grip (4) are transmitted to the gun interface unit (10), weapon interface unit (11), mission computer (12) and the control units (15). The said gun interface unit (10), generates control signals according to the discrete control and condition signals coming from the mission grips for controlling and firing the gun units in the aircraft and transmits these signals to the gun unit that will be controlled; and generates location information from the data coming from the gun unit location sensors and transmits this information to the gun unit that will be directed. The weapon interface unit (11) generates the power and discrete signals required to fire the laser guided missiles, unguided missiles, air-to-air missiles and antitank missiles which are integrated to the aircraft. Furthermore, it conveys the condition and status information of the discrete and power signals digitally via a defined data bus to the mission computer (12). The control unit (15) also reads the key
information coming from the control levers (collective & cyclic), by which basic flight controls are carried out, generates the power signals required for the mission grips in accordance with the discrete signals coming from the mission grips, and upon collecting numerous parallel data coming from the mission grips, transmits them serially to the mission computer (12).
In a preferred embodiment of the invention, there are provided two control units (15), one for the discrete signals coming from the pilot mission grip (2), and the other for the ones coming from the copilot left hand mission grip (3) and copilot right hand mission grip (4) (Figure 9, 10). The said control units (15) are conjugated and are backup units for each other. In case of failure of any one of them, the other control unit (15) enables the whole system to remain active.
