Austro-Hungarian Submaine Torpedo Launch Methods


Posts 1 to 5



Hello to All; I have detailed plans for the 1914-1918 Austro-Hungarian submarine "U-XIV" (ex 1912 French submaine "Curie") and noticed that torpedos were launched by some method other than tubes. It appeares that they were launched by some syster of linkages and arms. Can some one describe how this method worked and could it be done under-water? Also, how might it be modeled? Thanks in advance for any help. walls250


Stefan Drzewiecki was a Polish engineer who did a lot of work for the Russian navy, he was the one who developed these torpedo drop collars. Because of his Russian association, you my find any number of transliterations of his name, such as Dzhevetskii. The collars were pneumatic. The forward arm would swing out to a chosen angle while the back arm remained in place. In this way, the sub could fire a spread of torpedoes without any sort of gyro system. This salvo would release no bubbles or effect the sub's buoyancy, as would be the case with tubes. The fact that the system passed so quickly into antiquity is proof of its disadvantages. In the Russians' case, these included the tendency of the collars to ice up.


Thank you for the information. This helps in identifing some of the features on the drawings, such as a pivot located behind the torpedo and the parallel support arm. Very ingenious.
