"In this way, we will wait a few days for the selection of the air inlet of the new aircraft, and I need to discuss it with the company's senior management before I can give an answer!"

After finishing speaking, the vice president of Northrop left in a hurry, and he couldn't hold back something in his heart, so it was better to go back and discuss it quickly, after all, this matter is too big, if one doesn't do well, Northrop will really be doomed!

As it turns out, Northrop is always at his most astonishing efficiency when it comes to his own life and death. In just one week, the vice president flew a plane back and forth between China and the United States, and got a solution.

After two days of closed-door memories, the bosses at the top of Northrop finally made a decision, and after breaking the door of the conference room, a group of middle-aged people who were already in the prime of life seemed to have been drained of all their energy.

Only the vice president who needs to be stationed in Southwest Science and Industry does not have a decadent expression, but a relief after the big event is finally decided.

"It's up to you after this time, you have to remember that you can't let them announce the Galaette intake before the ATF project is announced, and you can do the rest."

At this moment, Northrop brought its essence as a capital company into full play, and in the face of life and death, what danger could not be taken.

After returning to Southwest Science and Technology, the vice president of Northrop looked very relaxed and no longer anxious, and sat down silently to preside over the continuation and finishing of the YZ1 verification machine.

Yang Hui was not too anxious, and leisurely convened the relevant production units of J-74. Chief Engineer Yu returned to the company two days ago with the test flight team, and also returned the first batch of J-74 refitting orders for the Navy's two flight regiments with up to 60 sorties.

For this order, Yang Hui is ready to work overtime to produce. First do not deliver foreign orders, and concentrate on the delivery of equipment for a flying regiment before 88.

At this time, it was inevitable to coordinate with many parties, and even slowed down the production of Jianjiao-7 in order to catch up with the schedule, which made Yang Hui tired for more than half a month, until the first J-74 walked off the production line and was pushed into the test flight station for test flight.

Seeing that everything was on the right track, Yang Hui casually came to find Northrop. In the end, it is time for the showdown between the two sides, and the development of the air intake tract cannot be delayed.

"How do you think about it? A two-dimensional rectangular air inlet is definitely not an option, we must have a more advanced design than a two-dimensional rectangular supersonic air intake."

The two had no superfluous words at the beginning. It's best to get straight to the point, and it's too lazy to bother with your saliva.

I already had the bottom in my heart, and Vice President Northrop calmed down: "There are always solutions, and it is not impossible to have more advanced technology than two-dimensional rectangular supersonic air intakes." It's even more suitable for new aircraft than your new intake tract, which is based on high-speed waverider and supersonic shock boost technology. ”

Could it be better suited for a new aircraft than a Garette air intake? Except for the plan that Yang Hui had overturned in his heart earlier. Yang Hui couldn't think of any more inlet technology than the Galatt intake that would be better suited to the use of the new aircraft.

But it's only been 87 years! Could it be that someone in the United States was reborn and came up with the DSI inlet technology in advance? That sounds a bit too!

"What does the gentleman mean"

Yang Hui couldn't believe his inference, and he didn't even dare to say too much when he asked, for fear of revealing some heavenly secrets, which would be short-lived if leaked, and he was a sinner of the nation.

Slowly, turn on the computer and skillfully enter commands to open the document. The familiar CATAI interface made Yang Hui very puzzled until he saw that the document had been loaded. A rough model appeared, which was relatively simple except for the air intake.

Although this model is incomplete, only the air intake is relatively complete, but after seeing Yang Hui see this thing, his heart is still turning over huge waves, although this plane is not recognized, but Yang Hui can still recognize the iconic Adam's apple in the air inlet of this aircraft.

That's right, it's the Adam's apple, of course, it can also be called the DSI inlet or more vividly called the mussel intake, Yang Hui can't believe that the Yankees took out the DSI inlet so quickly.

With a stomach full of questions, Yang Hui's mood at this moment was no different from the last time Vice President Northrop heard Yang Hui's garlett intake.

"This is"

"There is no doubt that this air intake is a completely new air intake, and it is very advanced. It shouldn't be on the new fighter planes we're working on, and as you can see in this picture, it's a futuristic technology. ”

Yang Hui didn't have time to listen to this guy's pretense of mystery, this thing was rotten by the Republic in the later generations, and in Yang Hui's opinion, it didn't seem to be mysterious.

The only problem is that Yang Hui can't understand why the air intake that was originally developed by Noukheid in the 90s came out in advance in 87.

"What kind of air intake is this? Is this the latest biomimetic achievement, is it to imitate the design of a man's Adam's apple? ”

Biomimicry is indeed a university question, but the current DSI inlet has its own unique source, the earliest study of the DSI intake, but not the last famous Nokheed.

"Bionic? No! We call it the DSI intake, and it has unmatched performance, not only is it lighter than all the traditional intakes, but it is also much more efficient than the traditional intakes, and I will tell you the truth, this is a fighter design from Boeing. ”

It's getting more and more confused, how can the DSI air intake thing have anything to do with Boeing again, and look at the appearance of this aircraft, and then think about the "future technology" just now.

This has to remind Yang Hui of the ATF project that the United States has only started now, which should be used as a new generation of fighter design, and only in this way can it be explained.

But when you think about it, you realize the problem: if the DSI intake tract is present in the ATF project, why did the F22 win in the end?

Even this Boeing design plan didn't even survive the first round, and it was directly defeated, which is too much to take the DSI air intake tract seriously.

These questions popped up one after another, and although they had nothing to do with the new plane, they did not prevent Yang Hui from having a strong sense of curiosity.

If we want to talk about the relationship between Boeing and DSI intakes, we must involve the ATF project, which began in 85 years, and a total of five companies first proposed the design of the scheme.

So there were five early options, and we all knew that the last YF23 failed because it was too advanced, but the most radical in the whole project was not the YF23, but the Boeing program, which didn't even have an official name.

Boeing's scheme is actually similar to the YF32 that Boeing lost again in later generations, the wing layout is more like Northro's YF23 design, there is no flat tail design, and the air intake is more like the Soviet MiG-1.44, which is a huge belly air intake, which is supplied to two engines.

This alone is not too radical, the really radical thing is that the Boeing program in 86 made the DSI intake tract.

Of course, Boeing knew through previous research that the adaptability of the DSI inlet at high altitude and high speed was relatively low, so Boeing used the radical DSI air inlet and gave a hidden flow control system in order to take care of the high altitude and high speed.

That's right, Boeing's plan is so bold that he uses the DSI intake and the air flow control system at a time when everyone else is using the Garette intake.

This thing is simply a zenith star, except for the last 0611 of the Republic of China, who dared to do this on the J-20 for special reasons, even Lockheed only used a fixed DSI intake on the fertilizer electricity.

It can be seen from this that the Boeing program is so radical that the natural Boeing program has not even been evaluated in the first round, but Northrop, as a competitor, has naturally conducted a certain amount of research on the Boeing program.

Boeing, the early founder of the DSI inlet duct, came up with the DSI inlet duct was naturally known to Northrop, and after some research, it was found that this inlet was indeed advanced, but Northrop had no idea about this thing, and this complex inlet with a flow regulation system was used in ATF projects that required supersonic cruise speed.

In that case, it is better to use it in the new F18 modification, which does not require high-speed performance, so that there is no need for such a flow conditioning system.

Only this thing can attract Southwest Science and Industry, as for how advanced the new F18 is after using this thing, it is not something that Northrop can manage, and what we need to do now is to first pass the difficulties in front of us. (To be continued.) )
