Aircraft Machine Guns

Caliber .30 and .50 Browning aircraft machine guns for aircraft from Index of Aeronautical Equipment with Navy and British Equivalents: Volume 5, Armament, March 1944.

AIRCRAFT MACHINE GUNS

Aircraft machine guns are used offensively or defensively against enemy aircraft or ground objectives, and are fired from fixed, flexible, or turret installations.

The caliber .30 and .50 Browning aircraft machine guns are recoil-operated, belt-fed, and air-cooled. Upon depressing the trigger, the gun operation becomes fully automatic, and it will continue to fire within the limit of the ammunition supply or until the trigger is released. Firing is accomplished manually by depressing the trigger, or electrically by a solenoid which is operated from a gun switch. The recoil of the gun supplies the power necessary to extract ammunition from the belt, feed it into the chamber, cock and fire the gun, eject the empty cartridge case, and move the next round into the feedway. Charging the gun for initial firing, or following stoppages, is performed manually, by retracting the handle of the slide group assembly, or remotely, by operating the control valve of a pneumatic or hydraulic gun charger.

These guns may be fed from the left or right side, and may be convened to either feed by reversing a few minor parts. A disintegrating metallic link belt is normally used to supply ammunition to the guns. The belt separates into individual links upon the removal of the loaded cartridge.

Guns may be mounted in the fuselage or in the wings, and require the use of gun mounts or adapters, depending upon the individual installation. When mounted to fire through the propeller arc, the gun must be equipped with a synchronizer, to prevent damage to the propeller.

Don’t Be A Dope V

Always check the oil! An angry tank crew stars in another “Don’t Be A Dope” training poster from Aberdeen Proving Grounds.

Always Check the Oil - Dont Be a Dope WW2 Poster

The tank crew is sore as a boil
For it ain’t according to Hoyle
     To get caught in a spot.
     So exceedingly hot.–
Joe Dope had checked all-but the oil!
Don’t be a dope! HANDLE EQUIPMENT RIGHT!

Ain’t the time to make up for a lack

With a month’s gummy dust on its back!
CLEAN IT EVERY 3 DAYS
 
Don’t be a dope! HANDLE EQUIPMENT RIGHT.
