3 early tank designs that were to ridiculous to function
Tanks are a staple of ground warfare. Militaries around the world deploy a wide range of tanks, but typically they conform to some basic principals. In nearly all of them, a large turret sits on top of an armored vehicle that moves on treads.
However, this wasn't always the case. In the early 20th century, engineers around the world were scrambling to figure out how exactly to pass uneven terrain and mobilize troops. This period of innovation resulted in today's technologically marvelous tanks, but before that, they had some truly outrageous ideas.
The Tsar Tank
The giant, bicycle-style wheels in front of the tank did prove effective for traversing a variety of terrains. But they severely limited the firing range of the 12 water-cooled machine guns situated in between the massive wheels. Thanks to two 250 horsepower Sunbeam engines powering either wheel, the Tsar could reach a respectable speed of up to 10.5 mph.
When testing began in a forest outside of Moscow, the rear wheel became mired in soft soil. Despite the Russian military's best efforts to free the 60-ton behemoth, it remained in that spot until 1923 when it was sold for scrap.
The Boirault Machine
In 1914, a few months before Britain began work on the "Little Willy" tank that would set the precedent for modern tanks, French engineer Louis Boirault presented the French War Ministry with plans for the Boirault Machine.Boirault's tank design was 26 feet high, and has been described as a "rhomboid-shaped skeleton tank without armor, with a single overhead track." The machine weighed a whopping 30 tons, and was powered by a single 80 horsepower motor which enabled the craft to move at a leisurely rate of less than 1 mph.
The singular tracked "wheel" that encompassed the Boirault was nearly 80 feet long and had a cumbersome 330 foot turn radius, earning it the nickname "Diplodocus Militarus," after one of the longest and most sluggish dinosaurs of all time.
The Screw Tank
The tank made it to a prototype stage, but was never fully realized and died on the drawing board.Recently, the idea of a screw tank has resurfaced, with the Russians seemingly perfecting the design as illustrated in the video below:
