On the other side of the channel, Vickers supermarin, UK.

This is a famous aircraft design company. The outstanding S-Series aircraft won the champion of the "Schneider Cup" international seaplane racing competition for three consecutive times in 1927, 1929 and 1931.

Therefore, 18 days after winning the Schneider cup for the third time, the British Aviation Department issued a development project numbered f.7/30, requiring the design of a single wing fighter to replace the old two wing fighter. This is the first time that supermarin has been given the opportunity to develop a single seater fighter.

Designing fighter planes for the army is a great honor for an aircraft company. Therefore, chaomarin company attaches great importance to it. Six months later, the chief designer Reginald Mitchell finally came up with the design scheme numbered 224.

Unfortunately, this scheme is screwed up, because we can't find a suitable engine!

If you want the aircraft to fly faster, you should minimize the flight resistance. As the champion of three racing aircraft, Mitchell deeply knows this index.

But he couldn't find the right engine.

Historically, the engine he needed was a Merlin engine, but now Rolls Royce has closed down.

Merlin's engine died without illness. Mitchell looked around the country and found that he couldn't find a liquid cooled engine with a power of more than 1000 horsepower! Without this engine, he could not design an advanced plane!

In this way, after a few years, Mitchell finally found a powerful engine, the Centaur engine produced by Bristol company! It's just that this is an air-cooled engine.

When it comes to World War II, Britain's industrial heritage is the strongest. It can be seen from the aviation industry that Britain's Merlin engine has even been exported to the United States and become a Mustang engine.

This also gives others a misunderstanding that the British liquid cooling is strong and the air cooling is weak. However, this weakness is also relatively liquid cooling.

Now, the Merlin engine has come to an end, while other engine manufacturers are still working hard. Therefore, this advanced air-cooled engine finally appeared.

(East China hero is no exaggeration. The Centaur engine in history was also launched in 38 years, a year earlier than the German BMW 801. Now, with Merlin gone, it's possible to come out a year earlier?)

This engine, in later generations, the final development model, can output more than 2500 horsepower, and now the initial model can also stably output 1800 horsepower!

It can be said that compared with Germany, the British engine has never been weak.

This is the inside story of the old capitalist countries! Even after World War II, Britain has always been in a leading position in terms of engines!

With the engine, although it is an air-cooled engine, it is not Mitchell's favorite type. After all, it can be used. Therefore, on the basis of this engine, Mitchell rolled out the drawings and redesigned, launched the 300 fighter and participated in the bidding of the f37 / 34 high-speed single seat fighter project of the Ministry of aviation.

In the process of designing this aircraft, a new BF109 aircraft has appeared in Germany. This aircraft is almost an epoch-making work! Mitchell had a deep hunch that there would inevitably be new struggles, so he had to go all out!

Now, it is the first test flight of the new aircraft. Compared with Germany, they have fallen behind.

"Mitchell, are you okay?" Asked assistant Josephine Smith, watching Mitchell crouch painfully with her stomach covered.

"Never mind, I can." Mitchell reluctantly stood up. Last year, he knew he had cancer, and what he wants most now is to see the test flight of the plane with his own eyes!

This is a brand-new work that he almost pushed back, just to suppress BF109!

At the same time, it is also the first all metal load-bearing skin cantilevered lower single wing aircraft adopted by supermarin company. All fixed weapons and retractable main landing gears of the aircraft are installed in the wing.

At the same time, the wing adopts the cantilever lower single wing with elliptical plane shape, which is very different from the rectangular wing adopted in other countries. Although the manufacturing process is complex and time-consuming, it has good aerodynamic characteristics and large lift drag ratio

From the appearance, it is completely different from the later generation of flamethrower. Its nose is too large and the front is quite strong, which is a compromise that has to be made in order to plug in the air-cooled engine.

Looking at the chief designer squatting on the side of the runway, super Marin's chief test pilot Matt summers got into the plane.

This is the first flight, but Matt is not nervous at all. He believes this is a very excellent plane!

With the roar of the motor, the propeller turned quickly. Matt pushed the accelerator. The fighter skidded and ran quickly on the runway.

Pull up the joystick and the plane flies easily. It's great!

Matt couldn't help cheering. He was very excited.

Retract the landing gear and test the climb! Relying on the outstanding high-power engine, the climb rate of this aircraft is higher than that of the previous racing aircraft!

"The climb rate is 762 M / min." Matt shouted on the radio, "now conduct a level flight test at maximum speed."

"Da..." a drop of sweat fell from Matt's forehead to his knee. Matt couldn't help wiping his forehead with his gloved hand.

Something's wrong! Why is the temperature in the cabin so high?

Matt has rich experience. He has found the problem. The front air-cooled engine is constantly pumping hot air into the cockpit. Soon, he will become a roast chicken!

"The cockpit is overheated and the test flight is terminated." Matt shouted on the radio. He looked at the water mist on his cabin glass and the surrounding was blurred.

So he finally couldn't help lifting the cockpit cover above his head!

The current height is 2000 meters, not counting the high altitude. Even biplanes without closed cockpit can fly up. When the cockpit cover is lifted, the cold air whizzes over. Now, it's finally cool!

In the history of spitting fire, the first flight was very smooth because it was a liquid cooled engine! Now, after equipped with air-cooled engine, the heat dissipation problem has always troubled designers!

In history, the storm fighter with this air-cooled engine did not encounter these problems, because after Britain had seized the fw-190, the intelligence of German engineers was inherited by British engineers.

They learned about the technical measures for the application of high-power air-cooled engines, arranged large annular air inlets, and used the strong slipstream of the propeller to forcibly cool the cylinder fins; The vibration is reduced by connecting the separate exhaust pipe of each cylinder to the exhaust port of the aircraft gill and the engine with the rubber component and the engine support.

But now, they don't know anything and everything is under exploration.

When the fighter with the open canopy landed back on the runway, everyone looked very ugly. Matt got off the plane and said to Mitchell, "I feel like it's spitting fire at me!"
