French pilot Jules Védrines in the cockpit of his Morane-Saulnier N in September 1915
Before Fokker’s famous gun-synchronizing device made his appearance, another system, invented by French manufacturer Raymond Saulnier, had already been tested in combat by Roland Garros, the first pilot to shoot down an enemy aircraft using a fixed machine-gun.
Unlike Fokker’s interrupt mechanism, which effectively blocked the machine-gun from firing when the rotating propeller’s blades were passing in front of the gun, Saulnier’s system worked as a synchronizer between the gun and the rotating blades enabling the bullets to pass between the blades of the spinning propeller. Due to the imprecise nature of an automatic gun's firing, variations in the spinning propeller’s velocity, and the very high speed at which any gear synchronizing the two had to operate made this system far from perfect with bullets hitting the blades every so often.
Saulnier’s friend, aviator Roland Garros came up with a solution, albeit a crude one, in the form of wedge-shaped bullet deflectors installed on the propeller’s blades. These would deflect any bullet that might have struck them. The system worked to a degree, considerably reducing damage to the blades, but it also reduced the propeller’s efficiency making the already slow Morane-Saulnier fighter even slower.
This particular photo shows the whole firing system with the deflectors clearly visible. Concerning these early weapon systems, I cannot help but wonder about how difficult and complex must have been for the pilot when he had to reload the gun (in this case, a Hotchkiss Model 1909 Benét-Mercié machine-gun) by inserting a new 25 round magazine, while at the same time piloting his aircraft and attempting to keep his opponent in sight.
Jules Charles Toussaint Védrines (1881-1919) was an early French aviator, notable for being the first pilot to fly at more than 100 mph (in 1912 flying a Deperdussin Racing Monoplane) and for winning the Gordon Bennett Trophy race in 1912.
During the Great War, he was posted to the French 6th Army flying reconnaissance and clandestine missions in his Blériot XXXVIbis. By war's end, he had flown over 1,000 hours.
On April 21st, 1919, Védrines was killed in a plane crash near Lyon while attempting to fly a Caudron C.23 from Villacoublay to Rome.
