What is the purpose of fire-control units in firearms? These systems typically interface with sensors that give the user information on the direction and range of a target. This information about Sig fire control unit can then be used to calculate an effective solution. In addition, optical sights can also give the user information to calculate range, which is useful when aiming a weapon at a target. However, the disadvantage of this technology is that the user gets less warning when tracking.
The disconnector is an integral part of most fire control unit (FCU) powered firearms. It prevents full-auto firing by preventing the sear from releasing the hammer until the slide is fully forward. Designed by John Browning, the disconnector prevents full-auto firing by preventing the sear from releasing the hammer until the slide is fully forward. There are two types of disconnectors: rotary and sear disconnectors. The disconnectors of both types are designed differently.
A shaped cam block is inserted into the sear housing pin in the disconnector system. The shaped cam block engages a corresponding cam cut on the rear lower trigger bar, providing a positive shelf for the trigger bar and increasing its resistance to displacement. This sear pin is compatible with a disconnector and a curved sear bar. In addition, the angled head of the sear pin helps the disconnector override resistance.
The advancement of computer technology has made it possible for a person to fire multiple rounds without reloading the weapon. Computers, often called fire control units, calculate the time delay between each shot and target. In the past, a person had to guess the gun’s range and target position from the target’s distance. These new systems can automatically adjust for any changes in the target range. Computer guns can also calculate elevation and target bearing. The AN/UYK – 7 is the main component of the computerized fire control unit. It can be used to track a target via its PPI and initiate tactical and non-tactical operating modes.
Gun order computer
A fire control unit powered firearm’s gun order computer computes ballistic corrections based on target motion and sight angle. This computer also computes fuze and train orders. It is connected to other units and transmits the corrector train and elevation orders to the gun mount. These components allow the shooter to make accurate and repeatable shots. The computer calculates these factors and then transmits them to the gun mount for use in firing the firearm.
The computer is the major unit in a linear-rate system and can be considered the counterpart of the surface range keeper in the main battery system. It performs the calculations required for fire control and receives the same inputs as the range keeper. For example, it receives the target elevation and rate of climb from the director, and it computes the elevation and gun train orders and transmits them to the firing unit.
Linear-rate antiaircraft fire control system
The linear-rate antiaircraft fire control system is complex equipment that controls dual-purpose guns. Like the main-battery system, it has several components that interact and function under various conditions. Its basic function is to determine the target’s elevation and rate of climb and adjust the system accordingly. The next sheets describe the various components of this system. A director and computer control the systems.
The two types of linear-rate antiaircraft fire control systems are the relative-rate system and the linear-rate system. The first type controls a machine gun and is used against low-flying short-range targets. Relative-rate systems differ from linear-rate systems in that they determine the target’s motion by measuring its angular velocity. This system is also used on battleships and cruisers. It is designed to work with 5-inch and six-inch guns.
