Measuring muzzle velocity
The AFV ASSOCIATION was formed in 1964 to support the thoughts and research of all those interested in Armored Fighting Vehicles and related topics, such as AFV drawings. The emphasis has always been on sharing information and communicating with other members of similar interests; e.g. German armor, Japanese AFVs, or whatever.

Post subject: Measuring muzzle velocity

A long time ago on the old AFV News forum someone asked about the method used to measure muzzle velocity. Below is showing one method using the Boulengé electrical chronograph. The shell is fired through a series of mesh grids with the difference in time and distance being used to calculate velocity.


Measuring the muzzle velocity of 18pdr guns during the First World War. (NAC PA-008284 & PA-008285)





Workman examines copper screens used to test the velocity of fired gun shells at Valcartier. (Feb. 1943, NAC neg. no. e000761170)



Female worker works with the laboratory equipment ("Boulange") connected to the copper screens used to test the velocity of fired gun shells, at the Valcartier test ranges. (Feb 1943, NAC neg. no. e000761171)
