Chapter 134： overheat

How did Hans, a strong-willed pilot, overcome these difficulties and fly this airplane with so many movements?

Hans at this time was almost soaked from head to toe, as if he was fished out of the water!

As soon as the cockpit lid was opened, a heat wave surged out, mixed with the smell of engine exhaust gas, and people could not believe that there would be people in such a harsh environment!

"The plane must be modified." Hans sat in the seat, almost collapsed, he said to the people outside.

If you want to modify it, you have to change it!

This test flight confirmed that the aircraft has good maneuvering qualities, such as precise control response, all of which, of course, benefited from good design and high-power engines.

However, the cockpit of the aircraft must be modified!

Front-mounted engine, the heat will be dissipated to the back, if it is a liquid-cooled engine, the heat can be taken away by the coolant and dissipated to other places, but air-cooled is no way!

The engine in front of it does not dissipate heat originally, and the heat flows backwards!

As a result, in this test flight, when the cockpit was sealed, the temperature of the entire cockpit rose to 55 degrees Celsius! Moreover, some of the exhaust gas from the front engine rushed into the cockpit. Without an oxygen mask, these exhaust gases would suffocate Hans!

When he came to the conference room, Hans, who had slowed down, said all this, everyone stopped talking, and his face was ugly.

How to do? Is it a mistake to use an air-cooled engine? In this case, it means a complete failure of this model!

of course not!

Kurt will never give up! During the First World War, Fokker manufactured many advanced aircraft. Now, after the war, Fokker must not decline!

Suddenly, Kurt remembered that after taking off, Cyric gave the order to use the oxygen mask in time. It seems that Cyric must know something! He is so amazing that he foresees the possible overheating of this aircraft in advance! Then, General Cyric, there must be a solution!

"General Cyric, do you have any good insights to solve these problems?" Kurt said to Cyric.

solve these problems! Cyric certainly has a good opinion! As a fan of World War II, Cyric knows quite in detail about the famous FW190!

In the early days of this aircraft, we encountered many difficulties, the biggest problem is overheating!

This is also the problem encountered by all air-cooled aircraft. Even the United States has been plagued by these problems. For example, the best-in-class B-29 strategic bomber in the United States has been facing the problem of engine overheating throughout its service period, until after World War II. Just solved.

Now, these problems, of course, are not problems.

"First, move the cockpit back." Cyrek said: "Moving the cockpit back by half a meter should greatly reduce the effect of engine heat on the cockpit."

Since the cockpit is too close to the engine, causing overheating, just move back!

"However, this will affect the pilot's sight even more," Kurt said.

The airplanes of this era are all propellers. The front propellers provide the airplane with forward power. At the same time, it is also a scourge, because it is necessary to prevent it from colliding with the ground!

Therefore, propeller planes are all rear three-point landing gear, and the front head is tilted high, so that the propeller can leave the ground.

At the same time, this also means that the pilot's front vision is very poor because the front is bulging!

Moreover, the engine is in the front, so the position of the pilot must be behind the engine! In this way, there is a huge obstruction in front. For liquid-cooled engines, the pilot can be directly next to the engine, while for air-cooled engines, the pilot has to move back!

moves back, the field of view is even worse!

"You can raise the cockpit slightly." Cyric said.

The only solution is to raise the cockpit. In this way, the exposed body of the pilot will be higher and the natural vision will be wider!

On the other hand, the Navy’s aircraft carrier is planned to be on the catapult! With the catapult, the plane takes off, so don’t worry!

Kurt nodded his head, let’s be a solution for the time being!

"Regarding the engine overheating, I propose to add a ten-blade cooling fan in front of the engine and enlarge the opening of the engine cowling." Cyric continued.

Historically, this was the solution. Since the cooling performance of the air-cooled engine is not good, I simply installed a large fan on it, and blow air against it to force cooling! This is definitely a correct solution. After this treatment, the heat dissipation problem of FW190 was finally solved.

Cyric’s simple plan is an improvement to this fighter, setting a tone. If there is a problem, it is normal. If there is a problem Then solve the problem!

And now, Cyric is absolutely supportive of this aircraft. At the same time, Cyric has more ideas!

"I have another suggestion." Cyric said: "In order to increase the range of this aircraft, the space on the aircraft can be effectively used. For example, the wing of the aircraft can also be made enclosed and used for storage. Fuel."

wing fuel tank!

A row of horizontally arranged ribs are strung together with a few long beams and then wrapped with skin to form the wings. Old-fashioned aircraft wing spars and ribs are made of wood, and the skin is made of canvas. Therefore, although the wing is hollow, it cannot be used.

And in this era, it has moved to an aircraft with an all-aluminum alloy skin. For example, in this new fighter, the spar, ribs and skin are all made of aluminum alloy.

Then, the space in the middle of the wings can be used, as long as it is sealed, fuel can be stored! The wing becomes a big fuel tank!

At the same time, there is another advantage. When the plane is flying, the lift force on the wings is upward, and the gravity of the fuel in the wings is positive and negative, and they will cancel each other out. The force on the wing is reduced, and the structure of the wing can be made lighter.

In later generations, wing fuel tanks are absolutely standard, and even large passenger aircraft have 70% of the fuel installed in the wings.

And now, to put fuel into the wing, Cyric is definitely the first to propose!

Hearing what Cyric said, Kurt was first happy, and then worried: "In that case, as long as one of the other's bullets hits the wing, the wing will burn."

Previous canvas-skinned airplanes were often hit with hundreds of holes in their skins when they came down, but they could still fly. Now, with a single bullet, the airplane may catch fire!
