- The Bliss-Leavitt Mark 7 torpedo was the first of Leavitt’s turbine-driven torpedoes to use the ‘wet heater’ design where water was sprayed into an external combustion chamber (burner) where a fuel (alcohol) was burning in the airstream. Heating the air from the pressure vessel gave significant improvement to a torpedo’s performance. The very hot gasses could, however, cause problems with the downstream materials. Spraying water into the burner had two advantages - the gasses were cooled, and the water turned to steam adding to the bulk of gasses delivered to the engine. In the USA, wet heater torpedoes were referred to as ‘Steam’ torpedoes, although the proportion of steam was a small fraction of the propelling gasses. Nowadays Leavitt’s turbines would probably be referred to as gas turbines.
The Mark 7 torpedo had a diameter of 17.7 inches (usually referred to as 18 inch), or 450 mm, and carried a warhead of 326 pounds of TNT. It had a maximum speed of 35 knots for a range of 2,000 yards, or 6,000 yards at 28 knots. The Mk 7 was introduced in 1912 and could be launched from surface ships and submarines, and remained in the US torpedo inventory into WW2 (to arm O class submarines and WW1 destroyers).
This model and animation are based on drawings from a 1916 manual. Certain components were not covered, and I have glossed over their operation. I have not included the complex oil distribution system feeding the bearings nor shown the oil accumulating in the torpedo’s bilge.
Animation created using Cinema 4D. Music credits are shown at the end of the movie.
Just incredible, these torpedoes. The engineering, the thought put into them to make them work. In addition, the guy who makes them all come to life with fully functioning digital models! Thanks Rob!
This animation is a thing of beauty.
It's an impressive amount of technology made just to be blown apart, i guess it was the guided missile of its time
What an impressive amount of engineering and technology for 1916 .. amazing.
Thank you for all your work you put into you videos, I hope that the research and time spent on sharing them brings you as much pleasure as it does for me watching them. Matthew.
A gas turbine torpedo at the beginning of the twentieth century!? No, I didn't expect this!!! 👍😍
ah yes the torpedo: a marvel of engineering making a object self steer under water with elegantly balanced :mechanics its purpose ? why to blow shit up of cours !
I have no idea why TH-cam recommended this video to me, but I found it interesting, and I liked the music. Thanks for your work!
Absolutely fascinting. Whilst having read about the various types before, I've never put much thought into how they work.
Amazing engineering and similarly amazing animation. These weapons have incredible intricacy, ingenious. Thank you for the excellent animation.
Thanks for another amazing and informative upload
Thanks for the good video. It's a reminder of the sophisticated level of technology used in WWI.
Thanks, I didn't know I wanted to learn how exactly a torpedo worked until now.
This is wonderful. I was always curious about the design and engineering of a torpedo. Great video, great amount of information. I appreciate it! :)
Well nice to see complex torpedoes and great music.
Great work, just great. This torpedo is a marvel of technology, back in 1916 ... Greetings from Spain!
Technical details beside, with this soundtrack it's like watching "How It's Made". Great video!
Marvelous engineering, even by today's standards.
Excellent video. Well done and thanks for the effort!
Well done and impressive video. I've always wondered how they worked. Thanks.
