Recoilless gun

Better results were obtained in 1943 when Dr. Hermann and collaborators of the Rhein-metall-Borsig AG constructed the 8cm PWK 43 (80mm Antitank Gun). Tire description of this gun, called in Frerich canon antichar modele 1943, was given by Travers and Touchard (Ref 3). They claimed that the turbocanon Delamare-Maze, invented in France about 20 years earlier, may be considered as the predecessor, of both the H/L and recoilless guns...

NC(13.15% N) 87, DNT 10 DBuPh 3%. At about the same time, the proplnt called FNH (Flashless-Nonhygroscopic) was developed. Its compn was NC(12.6% N) 74, NC(13.25% N ), 20, DNT 5 DPhA 1%. Designations NH and FNH are not used any more, being replaced by letters M or T followed by numbers 1,2,3 etc(See Tables V,VI VII). M means a proplnt adopted for service and T, one in the experimental stage Current US Single-Base Cannon Propellants. In Table V there are listed only three proplnts (MIAI, M3D M31) which are based on "Pyrocellulose (NC with 12.6%N), because the majority of proplnts are now based on "Blend (NC 13.15-13.25%N), which is prepd by mixing "Pyro (12.6%N) with Guncotton (13.4-13.45%N). The 1st component is sol in 2 l-eth-alc, while the 2nd is not. Cannon proplnts Ml, M6, Ml4 and recoilless gun proplnt M10 are based on NC with 13.25%N and so are small arms proplnts IMR (Improved Military Rifle) and M12 (listed here for comparison with cannon proplnts)...

A recoilless gun was open at both ends instead of one end as in the conventional gun. When the propellant charge exploded, the shell sped forward through the barrel while the gas blew backward through the breech. The gun, shell, and propellant were designed to make the forward action equal to the backward reaction, eliminating recoil.
