The Most Awesome Mechanical Design Manuscript in Human History

Every period is full of mechanical enthusiasts and designers, especially the brainy mechanical engineers of the former Soviet Union and Germany, who built some machinery and design manuscripts you may never have seen, but these brainy ideas have been physically present and you can only worship them!

1. Armored motorcycle

In December 1940, a design was submitted for an “armored motorcycle” with a movable curved armor cover on the motorcycle.

2. Moving armored fortress

The concept of the permanent fortification bunker was transplanted to the tank, and a mobile armored fort was designed.

The tank armor is 600 mm thick and equipped with large-caliber guns, small caliber guns, flat-fire machine guns and antiaircraft machine guns.

3. Manpower tractors

It has a human-powered tractor with multiple functions for transportation and plowing.

The designers believe that it is possible to obtain a larger transmission ratio through a multi-stage chain drive, have a traction force five times greater than that of an ordinary bicycle, and be able to pull a plow into the field.

4. The Birdman suit

The Birdman Suit, in 1955, Leo Valentin, a birdman, hoped to achieve man’s desire to fly by adding a pair of large wings to outer armor.

Unfortunately, in 1956, Valentine crashed to death while jumping out of the airplane to try this invention.

5. The duck-foot pistol

The duck-foot pistol is a popular weapon used by captains in the 19th century.

It has 4 barrels like duck feet, and can attack 4 enemies at the same time! !

But in real combat, it cannot attack the target directly in front.

6. Amphibious tank armoured vehicle travel mechanism

This is an amphibious tank armored vehicle running mechanism proposal submitted by Lieutenant  Б.К. Григоренко on March 2, 1944.

This lieutenant worked as a mechanic repairman before joining the army.

After joining the army, he worked as a repair shop mechanic in a tank unit, and later as a car repairman in a cavalry regiment.

During the war, he saw too much muddy roads, so he proposed to use screw rods instead of wheels and tracks to advance the tank.

It should be said that this plan is extremely advanced, and a similar vehicle really appeared in the Soviet Union many years later, that is, the SHN-1 all-terrain vehicle.

7. Combat vehicle “Karrar”

The total height of “Karrar” is about 3 meters, with 1 crew member, both the driver and the gunner.

The walking part is 6 spring-loaded legs controlled by the engine at the bottom of the turret.

Its walking method is to jump, which uses a motor to compress the spring and drive the support leg to contract and release.

Each jump can move forward 5-20 meters.

The battle room of “Karrar” is a sphere with a diameter of 1.25 meters.

According to the designer’s idea, the battle room is made of alloy armored steel plate, which can be rotated.

The weapon is 4 fixed PPsh41 submachine guns.

In order to combat tanks, “Karrar” also considered the subsequent installation of anti-tank guns and flamethrowers for engineers.

8. Krummlauf periscopic rifle

The design of the periscope rifle by Krummlauf can reach 90-degree bends, which has advantages in urban street warfare.

Soldiers hiding in the corner can also see the battle behind them through the mirror, which is a genius design.

But the problem of changing the direction of the bullet needs to be solved by aliens.

9. Human radar

During World War I, in Italy, when the radar had not yet appeared, air defense only relied on people to observe the sound of aircraft engines with their eyes and ears.

But because human hearing is limited, so someone invented this gadget.

10. The dual-turret tank

This is a dual-turret tank scheme.

The rear turret can be raised and lowered at a speed of 2 meters per second, and the maximum height can reach 10 meters.

The lifting power comes from a hydraulic lever.

The bomb feed mechanism and personnel access are hidden in an accordion airbag hose.

The designer believes that this kind of lifting turret can be raised in the woods to conceal the observation of distant targets;

It can also shoot high-rise targets in urban battles;

It can also be close to the building when the building is on fire, allowing the people in the building to evacuate to the ground through the lifting turret.

11. Steel armor

It may seem overly bulky, but it can actually withstand bullets, and when in danger, what needs to do is to drop the eye protection and kneel on the ground while retracting your limbs behind the shield.

Could this be the prototype for Iron Man?

12. Jet tank

It is powered by a solid rocket motor, travels on wheels, which can be replaced by a sled in winter.

It has two crews, a pilot and a gunner, who lie prone in a low and armored crew compartment.

The weapon system consists of six RS-82 rockets, which is divided into two launchers.

Between the two launchers is a ShKAS aviation machine gun.

Jet tank

The solid rocket motor of the “PT Jet Tank” is actually a direct transplant of the RS-132 rocket motor, which used electric firing.

The designers believed that the jet tank would be low profile, and it would be difficult to hit by the enemy at a top speed of 100km/h.

In battle, the jet tank could be used intensively and suddenly, the RS-82 rocket could shoot at enemy tanks, the machine gun could destroy infantry, and its whistling rocket engine could give the enemy a great psychological shock.

13. Round Battleships

In the early 1870s, Russian Vice-Admiral Popov proposed the bold idea of making battleships round, so that they could have the largest tonnage at the shallowest draught and smallest size to carry guns of the same size as larger battleships.

After demonstrating that the idea was feasible, the Technical Committee of the Russian Navy set up a panel to design it.

Round Battleships

Soon, several round warships were completed and put into service.

The warship was 30.8 meters in diameter and was equipped with an 11-inch cannon, two 4-pounder cannons, 16 37mm cannons and 12 pole torpedoes.

Due to the flat bottom of the boat, the waves swayed more than 1 meter high, which seriously affected the accuracy of shooting, and it was impossible to operate at all.

The Dnieper River, which was only 3 knots per hour, was rushed around by this.

It turned more fiercely when the gun was fired.

The ship would spin out of control when it encountered the current, and all the people on the ship were dizzy.

14. Heavy Battle Tanks

This is a heavy battle tank conceived by a reserve officer with the rank of lieutenant in March 1944.

He designed retractable side armour flaps for the tank’s tracks on both sides and it could be lowered to cover the tracks and the side of the load wheels during combat, which was similar to the lines of the side skirts found on modern tanks.

A pair of large rollers were also designed on the front of the tank, which is connected by a drive chain to the track travel system,

It could be rotated together to shield the front of the tank’s tracks from incoming shells, which is much like the minesweeper rolls of today’s minesweeper tanks.

Heavy Battle Tanks

The Lieutenant also proposed to strengthen firepower and install a large-caliber automatic gun for the tank.

But he didn’t mention the specific structure of the artillery.

15. Giant Rat Tank

The No. 8 mouse tank designed by the father of Porsche, the biggest feature is that it is big, and it is also the largest super tank in history so far!

If the intelligence personnel at the time did not investigate in detail but just took it for granted, it would definitely suffer a big loss.

Giant Rat Tank

This 188-ton behemoth is too heavy and even crushes the bridge, which can only use a weird breathing tube to connect two mouse tanks to dive across the river.

Hitler ordered the suspension, which ended the German super tank delusion.

16.Four-track tank

The four-track design scheme adds two tracks for the tank to improve its passing ability on extremely harsh terrain.

However, it was rejected because it would increase the weight by 5-6 tons, and the exposed chain drive at the bottom could easily get stuck in the rocks and mud and cause failure.

But the four-track design has not disappeared, because there is also the nuclear war tank 279 projects that we are familiar with.

Four-track tank

17. Steel hydraulic jet tanks

The designer not only designed ordinary tank cannons and machine guns for the tank, but also designed an astonishing weapon – steel hydraulic jet.

He set up a steel generator in the hull with iron oxide powder and aluminum powder composed of the aluminum hot agents.

Aluminum hot agent ignited before spraying a strong burning, iron oxide reduction into the molten state of molten iron, and then it sprayed out to destroy the target.

18. Balloon bombs

During World War II, Japan used balloons with 9,300 bombs to blow up the United States and Canada without leaving them.

Balloon bombs

But finally, only 357 of them hit their targets, and two floated back to Japan to blow up their own people.

I wonder how it is possible that 357 of them could have hit their targets, can it be detonated in the United States even if it hits the target?

19. Stick hand grenades

It was invented by the British, they put sticky glue on a grenade and throw it at a tank and it sticks to the tank.

Then it explodes and wins the war!

Stick hand grenades

Initially, the military opposed the manufacture of the weapon, but then British Prime Minister Winston Churchill made a big push for mass production.

As a result, 2.5 million sticky grenades were produced.

But when they were used in the field, there was a problem: the Germans seemed to be not very clean, their tanks were so dirty and covered in mud that sticky grenades couldn’t stick to enemy tanks!

20. Flying aircraft carriers

In 1933, two prominent airships, the USA Akron (ZRS-4) and Macon (ZRS-5), encountered atmospheric turbulence and crashed.

“Akron” was named by President Hoover’s wife in 1931.

Two years later, on 4 April 1933, it had made 74 flights and accumulated 1,700 hours in the air.

It was caught in a violent storm off the coast of New Jersey, broke apart and crashed into the Atlantic Ocean.

The “Macon” was an aircraft carrier carrying four Curtiss F9C-2 Sparrowhawk reconnaissance aircraft.

At the time of the crash, it was off the coast of California to head for Spur Point, south of Monterey and had just recovered its last aircraft.

A sudden gust of wind caused the craft to roll violently, its cross-tail came off vertically and punctured three helium pockets.

After a heroic 40-minute struggle, the craft crashed into the sea.

21. Power wing fighters

During World War II, the Germans attempted to develop a powered winged vertical take-off and landing fighter (Triebflugel).

This aircraft was tail-erected with a rotating ring on the fuselage, which in turn was fitted with three thin wings and angled jet engines on the wingtips.

When the engines start working, it can take off vertically like a helicopter.

Unlike helicopters, this aircraft could fly flat at high speed.

But the Germans soon discovered that this plan was useless, as it was difficult to land with the propeller tied to the engine.

22. Tsar Chariot

The “Tsar Chariot” was also called the “Bat Chariot” because of its triangular shape, which is similar to bats hanging upside down.

In August 1917, when the first prototype was demonstrated in front of the Imperial Court, it was rejected on the spot because the rear wheels could not get over an obstacle.

Lacking maneuverability, the Tsar’s Chariot was a sitting duck for enemy fire.

The only “Tsar Chariot” was sent to the scrap yard before it even entered the battlefield.

Tsar Chariot

23. Motorcycle artillery

This is the cannon used by the French in Vietnam in the 1950s.

This combination of motorcycle and gun was created because the French lacked the funds to provide more advanced weapons at that time and had to “obtain materials from local sources”.

This vehicle was mainly used by paratroopers.

However, it certainty say that this type of vehicle has very poor protection, and the reloading of artillery is also a problem, which makes the role in the war is very limited.

Motorcycle artillery

24. Dora Cannon

The Dora Cannon is an over-range gun developed by Germany during World War II.

It is supergiant artillery secretly developed after Hitler came to power.

The Dora cannon has a barrel length of 32.48 meters, a total length of 42.9 meters, a caliber of 800 mm, and a total weight of 1329 tons.

This is the largest cannon in the world, and a soldier can squat down in the barrel.

Dora Cannon

The cannon was a pain to maintain, with a total of over 4,000 people taking part in command, operation and guarding, and its projectile was appalling.

Each penetrator weighed 7.1 tons, a high explosive projectile weighed 4.8 tons, and propulsion fuel was between 1.8 and 2 tons, so only a few dozen projectiles were fired throughout World War II, which was a huge waste of manpower.

Here’s the problem.
