On the other side of the Channel, the United Kingdom, Vickers-Ultra-Marin. Pen, fun, pavilion www. biquge。 info

It was a well-known aircraft design company, and the outstanding S-series aircraft won the "Schneider Cup" international seaplane racing championship in 1927, 1929 and 1931.

So, 18 days after winning the Schneider Cup for the third time, the British Department of Aeronautics released a development project numbered F.7/30, calling for the design of a monoplane to replace the old biplane. This was the first time that the Super Marin was given the opportunity to develop a single-seat fighter.

Designing a fighter plane for the army is a huge honor for an aircraft company, so the super marlin company attaches great importance to it, and half a year later, the chief designer Reginald Mitchell finally came up with a design plan for the number 224.

It's a pity that this scheme spiraled, because a suitable engine could not be found!

If you want the plane to fly faster, you need to minimize the flight drag, and as a three-time champion of racing aircraft, Mitchell knows this indicator well.

However, he could not find a suitable engine.

Historically, the engine he needed was a Merlin engine, but now, Rolls-Royce has gone out of business.

The Merlin engine died without a hitch, and Mitchell looked around the country and found that he couldn't find the liquid-cooled engine he needed with more than a thousand horsepower! Without this engine, he would not have been able to design an advanced aircraft!

In this way, after a few more years, Mitchell finally found an engine with more power than the powerful, the Sagittarius engine produced by the Bristol company! Only, this is an air-cooled engine.

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

This has also caused a misunderstanding to others, thinking that the British liquid cooling is strong and air cooling is weak, but this weakness is also relatively liquid cooling.

And now, the Merlin engine has ended without a problem, and other engine manufacturers are still working hard to produce, so this advanced air-cooled engine has finally appeared.

(Huadong Zhixiong is not exaggerating, the historical Centaur engine also came out in 38, a year before the German BMW 801.) And now, with Merlin gone, it's possible to come out a year earlier, right? ）

This engine, in later generations, the final development model, can output more than 2,500 horsepower, and the current initial model, has been able to output 1,800 horsepower!

It can be said that compared to Germany, the British engine has never been weaker.

This is the essence of the old capitalist countries! Even after World War II, Britain has always been in the lead in terms of engines!

The engine is available, although it is an air-cooled engine, not the type that Mitchell likes, after all, it can still be used, so, on the basis of this engine, Mitchell rolled out the drawings to redesign, launched the 300 type fighter, and participated in the bidding for 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, which is almost an epoch-making work! Mitchell has a deep premonition that a new fight will inevitably arise, so he must give it his all!

Now, it is the first test flight of the new aircraft, and they are already lagging behind compared to Germany.

"Mitchell, are you okay?" Seeing Mitchell clutching his stomach and crouching to the side in pain, assistant Josephine Smith asked.

"It's okay, I'm okay." Mitchell barely stood up, knowing he had cancer last year, and all he wanted now was to see the plane fly with his own eyes!

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

At the same time, it is also the first all-metal load-bearing skin cantilever lower monoplane adopted by Super Marlin, and all the fixed weapons of the aircraft and the retractable main landing gear are installed in the wing.

At the same time, the wing adopts the cantilever lower wing of the elliptical plane shape, which is very different from the rectangular wing used in other countries, although the manufacturing process is complex, time-consuming and time-consuming, but the aerodynamic characteristics are good, and the lift-to-drag ratio is large

From the outside, it was completely different from the Spitfire of later generations, its nose was too large, and the front was quite thick, which was a compromise that had to be made in order to cram in the air-cooled engine.

Looking at the chief designer crouching on the side of the runway, Matt Summers, the chief test pilot of Super Marin, got into the plane.

It was the first flight, but Matt wasn't nervous, he believed it was a pretty good plane!

With the roar of the motor, the propeller spun rapidly, Matt pushed the throttle, and the fighter plane slid quickly on the runway.

Pull up the joystick and the plane flies with ease, which is simply amazing!

Matt couldn't help but cheer, he was excited.

Put the landing gear away and test the climb! Thanks to its outstanding high-horsepower engines, this aircraft has a higher climb rate than previous racing aircraft!

"The climb rate is 762 m/min." Matt shouted over the radio, "Now for the level flight test at maximum speed." ”

A drop of sweat fell from Matt's forehead to his knee, and Matt couldn't help but wipe his forehead with his gloved hand.

Something is wrong! Why is the temperature in the cockpit so high?

Matt is very experienced, he has already figured out what the problem is, the front air-cooled engine, is constantly blowing hot air into the cockpit, and soon, he will be a roast chicken!

"Overheating in the cockpit, terminate the test flight." Matt shouted over the radio, watching as his cockpit glass misted and the surroundings blurred.

So, he finally couldn't help but lift the cockpit canopy above his head!

Now the altitude is two thousand meters, not high-altitude, even a biplane without a closed cockpit can fly up, when the cockpit canopy is lifted, the cold air swishs over, and now, it is finally cool!

The Spitfire in history, the first flight went smoothly because it was a liquid-cooled engine! And now, after equipping the air-cooled engine, the heat dissipation problem has always troubled the designers!

Historically, the Storm fighter with this air-cooled engine did not encounter these problems, because after the British had captured the Fw-190 at that time, the wisdom of German engineers was all inherited by British engineers.

They learned about the technical measures for the application of high-horsepower air-cooled engines, arranged large annular air intakes, and used the powerful slipflow of the propeller to force the cooling of the cylinder heat sinks; Vibrations are reduced by converging the exhaust pipes of each cylinder into the exhaust port of the gill part of the aircraft and connecting the rubber components of the engine with the engine mount.

But now, they don't know anything, everything is being explored.

When the cockpit canopy landed back on the runway, everyone's faces were ugly, Matt stepped off the plane and said to Mitchell, "I feel like it's just breathing fire at me!" ”
