Coaxial (firearm)
The term coaxial in firearms refers to a coordinate axis . In armored vehicles, the installation of a secondary weapon is referred to as coaxial (sometimes also axially parallel in German-language literature ) if its barrel is always parallel to the main weapon. This arrangement opens up the possibility of using a common aiming device for the barrels arranged in this way . The secondary weapon is usually a machine gun. Examples of tanks are the M1 Abrams and the Leclerc . Corrections are necessary in the aiming device for sufficient accuracy of the primary and secondary weapon:
- Elevation corrections achieve the same point of impact for calibers with different ballistic properties.
- In parallel barrels, side corrections compensate for the side distance between the barrels in order to achieve the same point of impact.
Furthermore, manufacturing tolerances, material stresses, bedding and wear and tear mean that firearms are rarely identical with regard to their point of impact.
Coaxiality in the sense of the meaning of the axes of rotation results when insert barrels are used in firearms. This type of caliber reduction is particularly widespread with combined weapons .
