Chapter 134 Overheating

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

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

When the cockpit cover was opened, a heat wave gushed out, mixed with the smell of engine exhaust, making people unbelievable that there would be people in such a harsh environment!

"The plane, it must be modified." Hans sat on 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 handling qualities, such as precise control response, all of which, of course, benefit from good design and high-power engines.

However, the cockpit of the plane must be modified!

For the front engine, the heat will spread 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 there is no way for the air-cooled engine!

The engine in front has poor heat dissipation, and the hot air 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 jumped into the cockpit. If there is no oxygen mask, these exhaust gases will simply suffocate Hans!

When he came to the conference room and Hans, who had already come over, said all this, everyone stopped talking, and his face was ugly for a while.

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

of course not!

Kurt will never give up! During the First World War, Fokker made many advanced aircraft, and 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 simply amazing, he actually predicted the possible overheating of this aircraft in advance! Then, General Cyric, there must be a solution!

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

solve these problems! Cyric certainly has good insights! As a military fan of World War II, Cyric knows the famous FW190 in great detail!

In the early days of this aircraft, there were many difficulties, the biggest problem was overheating!

This is also a problem encountered by all air-cooled aircraft. Even the United States has always been troubled by these problems. For example, the most powerful 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 resolved.

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

"First, move the cockpit back," Cyric said. "Moving the cockpit back half a meter should greatly reduce the effect of the engine's heat on the cockpit."

Since the cockpit is too close to the engine, causing it to overheat, just put it back!

"However, this will make the pilot's line of sight more affected," Coulter said.

Aircraft in this era are all propellers, and the front propellers provide power for the aircraft to move forward. 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 raised very high, which allows the propeller to leave the ground.

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

Moreover, the engine is in the front, so the pilot's position must be behind the engine! In this way, there is a huge block in front. For a liquid-cooled engine, the pilot is directly next to the engine, but for an air-cooled engine, the pilot has to move back!

Moving back, the field of vision is even worse!

"You can raise the cockpit a little bit," Cyric said.

The only solution is to raise the cockpit, so that the pilot's exposed body is higher and the natural field of vision is wider!

On the other hand, the Navy's aircraft carrier is planned to have a catapult! With a catapult, the plane takes off, so don't worry!

Kurt nodded, let's just say this is a solution!

"With regard to engine overheating, I propose that a ten-blade cooling fan be added in front of the engine and a larger engine cowling opening," Cyric continued.

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

Cyric's simple plan can be regarded as the improvement of this fighter, and set a tone. If there is a problem, it is normal. If there is a problem, then solve the problem!

And now, Cyric absolutely supports this aircraft, and 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 wings of the aircraft can also be made closed and used for storage. fuel."

Wing tanks!

A row of horizontally arranged ribs is strung together with several long beams and then wrapped with skin to form a wing. Old-fashioned airplane spars and ribs were made of wood, and the skin was made of canvas. So, although the wings are hollow, they cannot be used.

In this era, it has moved towards an aircraft with all-aluminum alloy skins. For example, in this new fighter, the wing spars, ribs and skins are all made of aluminum alloys.

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

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

In later generations, wing fuel tanks are absolutely standard, and even 70 percent of the fuel in large passenger planes is installed in the wings.

And now, putting fuel into the wings, Cyric is definitely the first to come up with it!

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

In the past, canvas skinned aircraft often had thousands of holes in the skin when they came down, but they could still fly, but now, with a single bullet, it is possible to see the aircraft set on fire!
