Gun Synchronization

By: Kelvin Gonzalez

Browning Machine Gun, Cal .30, M1917A1

This weapon was used for the airplanes and machine guns on WW1.They set up a time when to shoot and when not to so it doesn't hit the propeller.A propeller is a type of fan that transmits power by converting rotational motion into Thurst.The interrupter stops the gun from firing while the synchronization method used a cam on the prop to fire the gun when the pilot was pulling the trigger. The pilot would squeeze the trigger, but the gun fired each round when the prop sweep engaged the cam, hence the prop fired the gun.



Until the beginning of World War I in 1914, aircraft were generally considered nothing more than a means of reconnaissance to observe enemy troop movements.But when the US noticed that they could start shooting from up top they started gaining more power.

How does it work?

Synchronizer gear allowed the gun to fire when the blade of the propeller was not in line with the barrel of the gun. The cam allowed the gun to fire at its free rate until the push rod stopped pushing the sear when the pilot pulled the trigger. It should also be noted that the rate of fire was tied to the speed of the engine so that when the engine was slowed down, the rate of fire was, too. In addition, if the engine was operating at very high speed, the synchronization might not allow for the speed of the propeller to clear the field of fire and you could shoot your own propeller off.

Was it Successfully used?

Yes it was successful because the first victory using a synchronized gun-equipped fighter is believed to have occurred on 1 July 1915 when Lieutenant Kurt Wintgens of Feldflieger Abteilung 67, flying the Fokker M.5K/MG.

Interesting facts

1.) One of the most important weapons of the war was the machine gun that had a profound impact on the nature of ground battles


2.) Until the beginning of World War I in 1914, aircraft were generally considered nothing more than a means of reconnaissance to observe enemy troop movements.


3.)Attitudes about combat planes began to change with the outbreak of war in Europe.
