Diagram of a British Constantinescu (CC) Gear

 
 
Perhaps the single most important technological development of the air war was the interrupter gear (also known as synchronisation gear). This enabled a machine gun to fire through the rotating propeller of an aircraft without hitting the blades. After the German Military adopted the system in May 1915, the Royal Flying Corps began to develop their own, introducing its first gear in March 1916. This is a diagram of a Sopwith-Kauper type gear.
