Does anyone know how the Germans were able to get the 88 shells to explode at a given altitude against bombing raids.
I imagine there was a fuse that could somehow be adjusted on each individual shell. Perhaps some form of 'dial' that would spin or adjust prior to firing which correlated to shell burst timing.
Problem as I see it though, the muzzle velocity was approximately 2,700 ft/s. In order for it to explode within 100 ft, you would need a precision to 1/27th of a second (or even greater for a smaller window.
Also it would seem as the shell reached it's apogee, it would begin to get slower and slower until v=0.
Then depending on the angle of the shot, as the planes approached from the horizon to a point vertical over the gun, the net distance from gun to plane would change quite quickly.
I imagine it was probably pretty hard to actually get shells to burst among the airplanes when you think of all the variables.
