If you want to make this large bomber fly, you must have a powerful engine, and now, the engine they use is the Wright R-3350 engine, this 18-cylinder star engine, can already output 2200 horsepower, more than the 1800 horsepower of the Atlantic airliner.

However, it is quite unstable.

In particular, this kind of star-shaped engine is in the front and rear rows, and the engine in the second row behind is more difficult to dissipate heat, so every test flight is accompanied by engine failure.

In just 23 test flights, they have changed 16 engines and have not solved the problem of engine overheating.

Later, I don't know who gave an opinion, why not refer to the design of the Germans?

At a time when American engineers were still having a headache with the cooling of the engines in the second row, the German planes had long since perfectly solved these problems.

If you directly apply for a Junkers-290 from Germany to study, it will definitely not work, the Junkers-290 is never exported, and only the Luftwaffe has one user.

However, there is also a passenger plane of the same model! The Atlantik One airliner uses the same type of engine! At that time, in order to develop this engine, the Xiusi company made a large amount of money, and later, the Atlantik 1 passenger aircraft became a joint production of the Xiuce company and the Hawker company.

After several arrangements, these engineers finally saw the engine of the Atlantik-1 airliner of the Theseus company, and when they opened the shell and saw the inside, they suddenly realized.

It turned out that this is how the German engineers solved it!

Since the heat dissipation of the second row is poor, then simply add a few air pipes outside, directly blow the wind to the second row, and force the heat to dissipate, which is simple, solves the problem and makes everyone suddenly.

When they came back, they arranged their engines in the same way, and just like that, the heat dissipation problem was solved.

After the test flight just now, it was confirmed that there was no problem at all!

This aircraft requires a high degree of secrecy, so many of the test flights of the aircraft are carried out at night and only start after dark.

As for why I did this, I'm afraid it has something to do with it!

"Now, we are facing a new problem, which is to design a remote-controlled turret." Captain Donald L. Pat of the Aviation Materiel Command, who was involved in the development of the aircraft, said: "Our bomber often flies at an altitude of 10,000 meters, so it is necessary to remotely control the turret to solve the problem. ”

Ordinary bombers are turrets that are directly controlled by people, after all, human reactions are the best.

However, an ordinary bomber is only a few kilometers at an altitude of several thousand meters, and this bomber often flies at an altitude of 10,000 meters, the outside temperature is minus 50 degrees, and the air pressure is also quite low, the pilot must sit in the pressurized cockpit, at this time, it is impossible to use an open unsealed manned turret.

Therefore, the remote-controlled turret is also a must.

The problem of the engine can be solved with the help of the Atlantic airliner, but the plan of the turret can only be done by themselves.

Hearing this, test pilot Allen also exclaimed: "Yes, as long as the problem of the remote-controlled turret is solved, there will be no problem with this aircraft passing the test." ”

After saying that, suddenly, he felt a pain in his stomach, what was going on? Could it be that there was something wrong with the drink that was drunk when landing?

After getting off the plane, he was a little thirsty, and as a result, the ground staff handed him a drink, he didn't think about it, he drank it all, now think about it, the ground crew seems to be a newcomer, I haven't seen it before?

His stomach was uncomfortable, so Alan didn't think about it anymore, and he pulled his legs and ran out.

There is no toilet in this huge factory, and if you want to go to the toilet, you can only go outside the factory, a few hundred meters away, and he probably can't wait.

Well, the usual way is to solve it in the grass outside.

Alan burrowed into the dark grass, found a no-man's land, opened his pants, and crouched down.

Then, it's time to have a good time.

When Alan got back on his feet, he felt that everything was relaxed, he lifted his pants, and just wanted to go back, when suddenly, behind him, a large hand covered his mouth.

Who's kidding themselves? As soon as Alan wanted to turn his head, he felt a violent impact on the back of his head, and his eyes were dizzy, and he immediately fell into a stupor.

He lost all consciousness and went into darkness.

It's built in the woods, opening up a large enough area, for a very important reason, for the sake of stealth, but it also makes it more difficult to defend.

If it were on flat ground, a sentry could observe the surrounding area, but now, with so many woods, it is easy to infiltrate.

In such a factory, there are tens of thousands of employees, and it is impossible for everyone to know each other.

Now, just like that, there was an accident, and as the chief test pilot of Boeing, Allen was quite important, and now, he is gone.

Half an hour later, the improvement suggestions for the aircraft were reached, and when everyone dispersed, they found that Alan was not there, if it wasn't for the chief engineer wanting to continue to discuss with Allen, everyone else thought that Allen had gone back to sleep!

As a result, it was discovered that Alan was gone, and he was found until dawn, but he was not found, and the person in charge of the base felt bad and hurriedly reported to the top.

Soon, an agent came with the dog and sniffed next to the poop outside for a long time, and the dog chased it for a long distance until it reached a river five kilometers away from the factory and lost its trace.

The other party must have run away in a dinghy.

Who did it, and why did you kidnap Allen? He's just a test pilot!

"Smack." In a small cabin, the lights were on, and Alan, who had recovered from a coma, gradually saw clearly, and in front of him were several men, at this time, each of them with fierce eyes.

"I'm just a test pilot, what do you want? If you want money, please find a company, and the company will pay a ransom for me, and I think I'm worth at least 50 million dollars. Alan spoke first.

As long as you find the company, the company will definitely save itself! When Alan said this, he actually wanted the other party to report to him.

"Allen, we want to know that half a month ago, you flew an XB-29 bomber to bomb New York, and we want you to give us justice." One man said: "We are all family members of the victims of this incident. ”

Hearing this, Allen was stunned: "What bombing New York, isn't that the Germans' business?" I don't know? ”
