German G7e Torpedo 1941
Ғылым және технология
The German G7e electric torpedo was made with several variants. This animation is based on the basic Type TIII, and is a revision of my Work-in-Progress video, with more detail and corrections.
The one major inconsistency is the Exploder shown in the animation, the Pi 1, was fitted to earlier models of the G7e (TI, TII) but the TIII actually carried the Pi 2 - impact and magnetic influence Exploder. Unfortunately no drawings have been found (yet) of the Pi 2, so the Pi 1 has been substituted, however the Pi 1 is an interesting design of an impact-only exploder.
The German G7e electric torpedo was probably the widest used torpedo arming the U-boat fleet during WWII. The original designs for an electric torpedo date back to 1916, and a production version was due to enter service in early 1919, but the end of the Great War and terms of the Versailles Treaty prevented Germany from manufacturing torpedoes until 1935.
Electric torpedoes, although slower and having a shorter range than an air-heater design, were cheaper and easier to build. At the start of WWII, Germany was working on a large number of different designs and propulsion systems, including hydrogen peroxide, battery and enhanced oxygen torpedoes. The principal design was the G7a - a conventional 7m long ’Whitehead’ air driven wet heater capable of 45 knots for a range of 5,000m, but this model was expensive to build and required highly skilled workers. The Electric version used used many of the same parts - gyro, depth control, warhead and pistol/exploder. However, it was only capable of 30 knots for a range of 5,000m if the batteries were pre-warmed to 30 deg C, and significantly less when launched with a cold battery. Nevertheless, it was ideal for submarine warfare.
Later G7e versions were capable of pattern running (FAT) or circling, including the ability to be set to follow and zig-zag across a convoy of ships (LUT). Acoustic homing torpedoes were also developed to home on propeller noise. I hope to be able to produce an updated animation that will demonstrate the FAT and LUT mechanisms (if I can get the manuals and drawings).
The animation illustrates the torpedo being launched from a Type VII U-Boat torpedo compartment. The actual launch mechanism is only a simple representation. It shows several of the basic principles for loading, maintaining and firing but is incomplete, inconsistent and often pure guesswork.
The animation replaces my earlier ‘Work-in-Progress ‘ video, which contains a number of inaccuracies that have been corrected (I hope) now that I have better drawings. The old version can still be viewed on this link:

I have never heard of any german torpedo "going off" early and killing the crew... The formost problem with the torpedoes was tactical, ie actually hitting the target.

the torpedo itself is the pinnacle of engineering. It is an incredibly precise and thoughtful mechanism of great complexity. The complexity of the systems is shocking, but it is also absolutely wonderful to think over technical solutions (it is a pity that such a miracle of technology was used to kill other people). The fact that the torpedo is a master of engineering is one thing, but the other thing is that your work on this presentation is a lot of effort and power of knowledge! I am shocked by the enormity of your work. I bow my hat down to the ground and I am shocked by the enormous wealth of your work !!! You are master!!!

"Its pity... other people". We would be still be apes if our brains werent capable to make the first axes, bow and spears to win of a more primitive clan. The modern human being is a filtrate or left over of an almost endless ammounts of strugles and hardships, where you had to outwit the other parties technological advantages. On the background, economics, healthcare and many other developments is assisting our chances in breakthroughs, the small little bits that make us lose or win. People dont grow faster and intelligenter brains out of its own or out of miracle. We had primiteves in europe, see the cave paintings in France, its the dumber part of our family that got wiped out. From a familly one child is doing better than the other one in school, and nature hardships, is selecting them to go trough and make he next generation or not. All what lives, overcame strugles, for it wouldnt exist in the beginning, and with such things requires offence, for there would be no food on your plate that way, perhaps we see animals not even as possible threats but see them mainly as food to consume. We lost the interest of thinking as them as fellow combatants, the only real danger left to us as animals (plants are also self living organisms, i dont think they would like to be consumed by vegetarians) are just other humans. Its a breakthrough in evolution, no other organism is achieving as much as we do, we outwitted our competitors, we wouldnt be alive otherwise. These machines belong to us, if not we would be overthrown eventually.

As a Torpedoman in Uncle Sams' Navy during the last days of the Mk. 14, I was surprised to find that, other than propulsion, the control mechanisms and exploder were very similar in operation......excellent video

Nothing to be surprised by: American torpedoes were initially based on the design of the Whitehead (Italian) and later Schwartzkopf (german) torpedoes that was purchased by US Navy, which later copied them under license by E.W. Bliss Co. (I'm ignoring the Howell-torpedo and other creative american "torpedoinventions" during the late 18th century). Most effective torpedoes can be traced back to the original Whitehead-designs, so it's easy to identify the internal mechansims of most wet-heater torpedoes from ca 1870 to 1960.
Best naval animations on youtube!
You did a more than excellent job in both modelling, explanation of the different mechanisms and the procedures of (launching) a torpedo. Your videos are clearly underrated versus other channels.

I was eagerly waiting to see German submarine torpedoes on this channel, this one didn't disappoint. Is there enough open source data to hope to some day see a similar animation of the G7a? How about models with more advanced guidance such as the Fat, Lut, or the infamous G7es acoustic torpedo? Thanks for your work.

I have no plans to make a G7a model as it uses the same parts (Gyro, Depth gear, servos, warhead and pistol) as the G7e. The propulsion is a straightforward compressed air - wet heater - 4 cylinder radial Brotherhood type engine that I have already illustrated in the British Mark 2 of WW1 model. I can see nothing new or radical about the G7a engine. What is interesting are the advanced mechanisms. I have hope of getting drawings of the FAT mechanism inside the torpedo, but despair of finding the torpedo LUT mechanism drawings. As for the G7es Kaunkönig T V, I don't have the drawings and anyway only 761 T V were fired of which only 112 hit (14.7%). Infamous? I would much rather model the US Mark 24 'Mine' (accoustic anti-submarine homing torpedo - Fido) from 1943 - if only I could get the drawings.

@@vbbsmyt Thank you very much for the detailed answer, really appreciated. Makes sense that the G7a would be redundant and thus not so interesting to model other than for completion/reference. Fingers crossed you do get your hands on the drawings for FAT/LUT mechanisms. As for the T V, I admit that "infamous" was over-blowing it considering its actual impact, especially compared to the Mark 24 which would be fascinating to see. (Any plans for this one, by the way?) My wording was more about its perceived danger, which as for a lot of late WW2 German weaponry (V-2, Hs 293, Me 163, Wasserfall...) was far exceeding its actual impact on the war - other than further draining scarce German resources.

Wonderful work. I always wanted to understand how it works and finally I can know it in detail. Thanks 👍
Thank you so so much! I was waiting ages to see how this one came out. I had no idea just how much maintenance was required to keep them heated and charged. Now when my crew in SH3 (with full interior) get tired all the time in that compartment, I will have more respect. I had no idea about the hydrogen either. I guess I never considered it. And you're the first person I've seen that shows me how the Vorhaltrechner interfaces with the torp. The only thing I'd love to see now is the steam powered A model. Thank you again!

Also one question, regarding the hydrogen. At one stage, during the animation, the hydrogen was removed by means of an extractor system during charging. But during the heating process, it just shows the LP compressed air being blown in, which shows the hydrogen being vented over the side. Where does this hydrogen go?
@vbbsmyt
2 жыл бұрын
Hydrogen gas, mixed with the air in the battery compartment, is vented out of the torpedo though the vent valve (05:32) and into the torpedo compartment (torpedoes in the reserve storage compartments) or through the open torpedo rear doors. I shudder at the idea of leaving the rear doors open all the time, but this is what the Instructions imply. Then the hydrogen is extracted by the ventilation system and mixed with the whole submarine atmosphere, which dilutes it well below dangerous levels, until burnt up when the diesel engines are started.
