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

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

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

"The plane, it has to be modified. www.biquge.info"Hans sat in his chair, almost collapsed, and said to the people outside.

If you want to revise it, you have to change it drastically!

This test flight confirmed that the aircraft has good handling qualities, such as precise control response, all thanks to good design and high-power engines.

However, the cockpit of the aircraft must be modified!

If the engine is liquid-cooled, the heat can be taken away by the coolant and dissipated to other places, but the air-cooled engine can't help it!

The engine in front of it is not good for heat dissipation, and those hot gases flow 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 gases from the front engine jumped into the cockpit, and without the oxygen mask, these exhaust gases would simply suffocate Hans!

When Hans, who had come to the conference room, had recovered and told all this, everyone stopped talking, and their faces were ugly.

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

Of course not!

Kurt will never give up! During the First World War, Fokker built a lot of advanced aircraft, and now, after the war, Fokker must not decline!

Suddenly, Kurt remembered that after taking off, Ciric gave the order to use an oxygen mask in time, and it seems that Ciric must know something! He was so godly that he actually predicted in advance the possible overheating of this aircraft! Then, General Ciric, there must be a solution!

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

Solve these problems! Ciric certainly has a good insight! As a military fan of World War II, Ciric knows the famous FW190 in quite detail!

In the early days, this aircraft encountered a lot of difficulties, and the biggest problem was overheating!

This is also a problem encountered by all air-cooled aircraft, even the United States, has been troubled by these problems, for example, the United States' best B-29 strategic bomber, throughout its service, has been facing the problem of engine overheating, until after World War II.

Now, none of these problems are of course a problem.

"First, move the cockpit back." "Moving the cockpit back half a metre should significantly reduce the impact of engine heat on the cockpit," says Ciric. ”

Since the cockpit is too close to the engine, causing it to overheat, then simply go back to the rear!

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

The planes of this era are all propellers, and the propellers in front provide the aircraft with forward power, and 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 cocked very high, which allows the propeller to leave the ground.

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

Moreover, the engine is in the front, so the pilot's position must be in the back of the engine! In this way, there is a huge shield in front, for liquid-cooled engines, the pilot can be directly next to the engine, and for air-cooled engines, the pilot has to move back!

Move back, and the vision is even worse!

"The cockpit can be raised slightly." Ciric said.

The solution can only be to raise the cockpit, so that the pilot's exposed body is taller and the natural vision is wider!

And on the other hand, the aircraft carrier of the Navy, it is planned to go on a catapult! There are catapults, the take-off of the plane, there is no need to worry!

Kurt nodded, let's think it's a solution!

"Regarding engine overheating, I propose that a 10-blade cooling fan be added in front of the engine and the engine fairing opening can be enlarged." Ciric continued.

Historically, this is how it was solved, since the cooling performance of the air-cooled engine is not good, simply install a big fan on it, blow air on it, and force cooling! This is definitely the right solution, and after this treatment, the heat dissipation problem of the FW190 was finally solved.

Ciric's simple plan can be regarded as an improvement for this fighter, setting a tone, if there is a problem, it is normal, if there is a problem, then solve the problem!

And now, Ciric is absolutely supportive of this aircraft, and at the same time, Ciric has more ideas!

"I have one more suggestion." "In order to increase the range of this aircraft, the space on the aircraft can be used efficiently, for example, the wings of the aircraft can also be made closed to store fuel," said Ciric. ”

Wing fuel tanks!

A row of transversely arranged ribs is strung together with several long beams, and the outer edge is wrapped with a skin to form the wing. The wing spars and ribs of vintage airplanes were made of wood, and the skin was made of canvas. So, although the wing is hollow, it cannot be utilized.

In this era, it has moved towards an all-aluminum alloy aircraft, such as this new fighter, the wing spar, ribs and skin are all made of aluminum alloy.

Then, the space between the wings can be utilized, and as long as it is sealed, fuel can be stored! The wing becomes a big fuel tank!

At the same time, there is another benefit, when the aircraft is flying, the lift on the wings is upward, and the gravity of the fuel in the wings is positive and negative, and they 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 were absolutely standard, and even large airliners had 70% of their fuel in the wings.

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

Hearing Ciric's words, Kurt was first happy, and 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, the canvas covered airplane, often when coming down, the skin was beaten to a thousand holes, but it could still fly, and now, a bullet may see the plane on fire!
