The WW2 European fighter has a cannon of a gun at the center of the propeller part of the nose, that is, a propeller shaft (drive axis), and has a gun barrel there.Why did you need to do this kind of trouble?
わざわざエンジンに機関砲を通す価値は？1935 (Showa 10), Dobowatin D.Fighter with a groundbreaking mechanism of 501 has begun in France.This aircraft, which is a so -called reciprocating machine (an airplane that turns propellers by turning propellers with a reciprocating engine), makes propeller shaft (driving axis) a hollow structure, and fires a shell forward through a gun in it.Motor Canon was installed.Looking at the aircraft from the front, there is a gun mouth of a gun in the center of the propeller.
When the driving axis is hollow, it becomes a complicated mechanism, but why did you have to force the machine gun on the propeller shaft?It is related to the structural problem of the fighter at the time.
For machine guns and machine guns, in the case of fighters aiming at the pilot and drawing a trigger (not on board), the closer to the nose, the higher the target accuracy and the higher the hit rate.This "approaching the nose" was a bigger problem for a single reciprocating engine fighter until the second World War II.The mainstream was a shape with a propeller on the nose, and the propeller itself was in the way.
