Air defense gun is mounted on the loader's hatch in the turret of the tank and is controlled by the loader .It is primarily used to attack low flying armored vehicles. Presently the gunner has to expose himself to track the enemy vehicle and attack the target and so he becomes vulnerable to external foes, added to it he has to manually adjust the desired elevation and depression of the air defense gun.
Our project focuses on the safety of the gunner by employing embedded systems to position the air defense gun without having the gunner exposed. Presently the air defense gun is maneuvered manually both in azimuth and vertical planes. This entails operation of the air defense gun by the loader in the hatch opened condition, exposing the loader to the attack by the enemy. Also this manual operation will be a tiring activity .
The system should enable sighting of the target through a sight, aiming the target in hatch closed condition by slewing and elevating/ depressing anti-aircraft gun The system should enable the rotation of loader's hatch in azimuth plane both in anti-clockwise and clockwise direction through 360 degree. The movement of air defense gun in the vertical plane is from -10 degree to +70 degree. The system also requires automatic stopping of gun movement if it attains the extreme positions in the vertical plane.
In automatic firearms , burst mode or burst fire is a firing mode enabling the shooter to fire a predetermined number of rounds , usually 2 or 3 rounds or 100+ on anti-aircraft weapons , with a single pull of the trigger. This firing mode is commonly used in submachine guns , assault rifles and carbines
The burst mode is normally employed as an intermediate fire mode between semi-automatic and fully-automatic , although some firearms lack a "full auto" capability and use a burst mode instead. The number of rounds fired in a burst is almost universally determined by a cam mechanism that trips the trigger mechanism for each shot in the burst. Some designs will terminate the burst if the trigger is released before the burst is complete, while others will reset the cam position, so the next burst will fire a full number of rounds.
• PC interface with the circuit for future processes.
• Updating and displaying the number of bullets fired.
• Using image processing for targeting the gun with the hatch in closed position.
• Use of advanced motors for a better control of position.
• Use of real time cameras for tracking the movement of the air defence gun.
