War Tank on One Wheel

Look what crazy thing I found.
The Idea is, that one man, armed with a machine gun, fastly can drive through a battlefield.
Back in the WW I this little machine would have been very frightend battlemachine.
The picture shows an English Wheel tank. The Germans also invented some Wheeltanks, but this tanks were only prototypes, because they would have been not wery effectiv in a a battlefield withe the new "real" tanks (like the British "Mark tanks" or the German "A7V")

War Tank on One Wheel OPERATED BY ONE MAN
Suddenly, through the drifting smoke of a hard-fought battle, rush weird, one-man fighting tanks. They have the appearance of disk wheels and roll like hoops across the battlefield. Pouring out machine-gun fire, they leap over trenches, vaulting across on strange steel crutches to pursue the disorganized enemy.
Such is the startling vision foreseen by a New York inventor. He has just obtained a patent upon a unicycle-type tank which he believes will revolutionize battlefield tactics.

Housed inside the armored body, the operator will steer the single main wheel by means of two small auxiliary wheels at the rear. A turn of the handlebar lifts one stabilizing wheel and lowers the other, shifting the balance of the machine and turning it to one side or the other. An internal gear mechanism, operated by a motor inside the body, drives the wheel ahead at remarkable speed.
By a simple process of inverting the streamlined pants on the stabilizing wheels, so they form balancing floats, and attaching propelling fins to the main wheel, the tank can be turned into an amphibian capable of plunging into a stream and rolling to the other side.
One of the oddest features of the revolutionary machine is formed by the steel-tube crutches that project ahead on either side like medieval lances. As the tank rushes upon a trench or obstruction, the operator will drop the tubes so they dig into the earth and the whole machine will vault through the air to the other side. An open-type form of the vehicle, which is shown on our cover, has also been devised by the inventor. Without the armored body or the crutches, it is designed for highway use.
In various parts of the world, recently, engineers have been reviving the idea of the unicycle. Attracted by the economy and compactness of a one-wheeled vehicle, they have been attacking anew the problems of balance and propulsion which have been the stumbling blocks in the path of the inventors.
In England, an Italian inventor has just demonstrated a single-passenger unicycle in which he claims to have reached speeds of 100 miles an hour and to have made 280 miles on a gallon of gasoline. In the near future, he plans to bring the machine to the United States and demonstrate its adaptability to American highways. Perfected after more than ten years of experiment, this odd machine rests solely upon one huge pneumatic tire encircling the driver, and dispenses entirely with exterior steering apparatus. The metal rim within the tire supports the frame and driver’s seat and is rotated by a motor of one and three-fourths horsepower. To guide the vehicle to left or right, a steering wheel tilts the central frame with respect to the wheel, shifting the driver’s weight and thus steering the hoop. Models of various sizes are contemplated, the diameter of the hoop being suited to the height of the driver, so that a tall man, according to the inventor, would use a larger unicycle than a short man.

The russian "Tsar Tank" - prototype of WW1

The german "Go 229" also named Horton HO IX 229

length:   7,47 m

wing spread:   16.76 m

height:   2.81 m

crew:   1

engine:   2 Jumo 004 B-2 engine with 900kp

max. speed:   ~1000 Km/h

operating distance:   ~1900 km

 

The Go 229 jet aircraft was the first operational flying wing airplane equipped with jet engines. In the history of aviation, it deserves a special place, along with the Me 262 and the Me 163. But the Go 229 is certainly the one that looked the more out-of-this-world.

The German started researching the flying wing aircraft concept in the Twenties. This idea had been explored by Alexander Lippisch, and was further developped by the Horten brothers.
At the end of the Thirties, a few prototypes of the aircraft had been built, with "pusher" propeller engines. The first flights were made in 1937. The beginning of the war served as a catalyst, accelerating the design.

In December, 1944, the German were still working on this strange aicraft, aiming at manufacturing a fighter-bomber equipped with Jumo jet engines. The end of the war in Europe prevented the Nazi from using the airplane against Allied targets.

 
Had it been used to attack the United Kingdom (which at the time was getting early warnings of invading aircraft thanks to the recently invented radar), the Go 229 jet aircraft would have been totally invisible to the radar waves. The German engineers knew it and so they can be considered as the inventors of the stealth aircraft concept, which would later on be developped by the Americans.

The HK G11

Caliber: 4.7 mm caseless
Action: Gas operated, rotating breech
Overall length: 750 mm
Barrel length: 540 mm
Weigth: 3.6 kg empty
Magazine capacity: 50 or 45 rds

Rate of fire: ~2000 rounds/min. (3-rounds burst)

The German government decided at the end of the 1960's to replace the G3.

The initial studies lead to the idea of the small-caliber, rapid-fire rifle that fires caseless ammunition. To ensure sufficient stopping/killing power for small-caliber bullets used, the rifle should had have the three-round bursts capability and high capacity magazine.

Early prototypes featured one 50 rounds polymer magazine, while latest versions featured 45 rounds magazines - one in the loaded position within the movable housing and two spare magazines on the top of the rifle, asides from the loaded magazine.

 The rifle features unique cylinder breech/chamber system that rotates 90 degrees. The cartridges in the magazine are located above the barrel, bullets down. Prior to each shot, first cartridge is pushed down from magazine into chamber and then breech/chamber rotates 90 degrees to align the cartridge with the barrel (see pic).

The firing cycle process is roughly:

-As the cocking handle on the side is rotated clockwise by the weapon operator

-A round is dropped into the revolving chamber vertically (a loading piston assists this process).

-The chamber rotates 90° until it is lined up with the barrel. This completes the chambering of the round and cocking of the firing pin.

-When the trigger is pulled, a firing pin ignites the primer, which then ignites a powder booster charge that pushes the bullet into the barrel. The solid block of propellant is broken up to increase the ignition surface area and ignites, accelerating the bullet out of the barrel.

 -As the projectile is accelerating up the barrel, recoil forces drive the barrel, magazine, chamber and operating mechanism rearwards within the weapon, dissipating energy for single shot and fully automatic modes but allowing burst mode to deliver three projectiles downrange before buffering occurs.

 -Gas tapped off from the barrel rotates the chamber and actuates the loading mechanism then rotating the chamber back to the vertical original position until it is lined up with the feed mechanism and the process repeats.

The caseless ammunition in its early appearance was designed as a block of the propellant, coated with flammable laquer, with bullet and primer "glued on" the propellant. Final ammunition design DM11, that appeared in the mid-1980s, featured "telescopic" design, when bullet was fully enclosed in the block of the propellant. The cartridge propelled the bullet that weights 3.25 gramms, to the 930-960 meters per second.

Early prototypes were prone to the ammunition cook-offs during the sustained fire, but later Dynamit Nobel solved this issue.

In the late 1980s the Bundeswehr (West German Army) began the field tests of the pre-production G11s. After the initial tests, some improvements were devised, such as removable optical sight, mounting of two spare magazines on the rifle, and bayonet/bipod mount under the muzzle.

The modified variant, called G11K2, was tested in 1989, scoring at least 50% better combat accuracy when compared to G3 rifle. Initial batch of some 1000 G11K2s was received by Bundeswehr in 1990 or so, but due to some reasons the whole programme was cancelled by German Government. Main reasons of this cancellation were, in my opinion, the lack of fundings after the re-union of the West and East Germanies, and the general NATO policy for unification of the ammunition and even magazines for the assault rifles.

The slightly modified G11 was also tested in the USA under the ACR (Advanced Cobat Rifle) programme, in 1990. The ACR programme was not intended to result in adoption of the new rifle for the US Army, just to test new technologies and designs, and the G11 proved itself as a very accurate, comfortable to handle and fire, and reliable weapon.
