In any case, the advent of the "model machine" has made the Republic a big step forward in terms of having a modern air early warning and command capability!

It was also at this time that another piece of good news came.

The Z-9X demonstrator, which was carried out to validate the ultra-high-speed heavy-duty helicopter project, and was equipped with a small forward-swept fixed-wing and a vectored thrust ducted propeller on the Z-9 helicopter, finally made its first flight.

The development difficulty of the straight-9X is much more difficult than imagined, compared with the straight-9, the straight-9X has the dual characteristics of fixed-wing aircraft and rotary-wing aircraft, and also has the design difficulty of both fixed-wing aircraft and rotary-wing aircraft, the republic has always been weak in the aerodynamic design and theory of the rotorcraft, and now the installation of these two sets of things on the rotorcraft is even multiplied with difficulty, and it was originally expected to be able to test the flight of the straight-9X project at the beginning of 96, It was not until the middle of '97 that it made its first flight.

…………………………………………

The comrades of the navy were particularly excited, and the Zhilu Daozhi-9X was the future aircraft carrier of the Republic, and the carrier-based early warning aircraft and carrier-based air tanker were doing technical research, and they rushed to the Bingcheng Aircraft Factory as soon as the Zhilu Daozhi-9X made its first flight.

"Brother Lin, thank you, thank you, thank you, you have helped us a lot." General Wang Xu, the commander of the naval aviation unit who came to Bingcheng, stepped forward and held Lin Hongfei's hand tightly, and said in a speechless voice.

On the contrary, under the premise that the country is already aware that aircraft carriers will inevitably develop aircraft carriers as the core of China's naval fleet, aircraft carrier-based aircraft, carrier-based early warning aircraft, and other related auxiliary carrier-based aircraft have become problems pondered by the navy and the navy all day long, and the demand for certain special aircraft is even much higher and more numerous than that of the air force. Among them, the technical difficulty of aircraft carrier early warning aircraft and aircraft carrier air tanker aircraft is the most!

Aircraft carrier carrier-based fighters are good to say, the republic is secretly seeking to obtain from Ukraine the prototype T-33 of Russia's main heavy carrier-based fighter SU-10, with the character of the poor Ermao family who can't even get their underwear, everyone is full of confidence in getting the T-10 prototype, and it is only a matter of time before they get the T-10, but the aircraft carrier carrier-based early warning aircraft is really too much of a problem, and the woolly bears have not solved the problem of fixed-wing early warning aircraft on the ship until the collapse of the Soviet Union, and they have no choice but to do so. Helicopters had to be used as carrier aircraft.

As for carrier-based air tankers? Well. For the United States and the former Soviet Union, where overseas military bases are spread all over the world, they don't need this thing, but the problem is that the republic doesn't have this thing, so the dispensable thing like carrier-based air tankers becomes extremely necessary for the Republic Navy.

Just when everyone is at a loss and can't find a way to solve the problem. Lin Hongfei suddenly proposed a brand-new concept of a high-speed aircraft that can take off from an aircraft carrier by combining fixed-wing aircraft and rotary-wing aircraft, which made the navy ecstatic.

What made the Navy even more ecstatic was that. Lin Hongfei's plan is indeed feasible after demonstration. And when this kind of plane really appeared in front of the leaders of the Navy today, the generals were already so excited that they almost cried with joy.

"General, this is what we should do," Lin Hongfei understood why General Wang was so excited, because he also felt the same way, "Only our country's army is strong." The fists are hard enough so that we don't get bullied...... As long as our army becomes strong as soon as possible, the Americans will not dare to point fingers at our North County 100 and North County 200 in the future. ”

In the past six months, the Americans and the French have been pointing fingers at the Beijun 100 and Beijun 200 planes of the Second AVIC Group. scolded the Americans and the French for being shameless, and now when I heard Lin Hongfei say this, I immediately nodded again and again, and was deeply touched by Lin Hongfei's words, "What I said is that only when we become strong as soon as possible can we ensure that we will not be bullied by others......"

Speaking of this, General Wang Xu glanced at Lin Hongfei deeply, "Xiaolin, speaking of which, I should thank you the most, if it weren't for your efforts in the former Soviet republics, our country's military industry would not have developed so fast." ”

"Don't talk about this, it's not the credit of one person or two," Lin Hongfei smiled, "Let's hurry up and take a look at our baby." ”

"Yes, yes, let's take a look at our baby first!" General Wang Xu nodded again and again.

………………

In front of the senior generals of the HNA is a Zhi-9 helicopter that they are already familiar with and is temporarily painted in military green, but unlike the carrier-based Zhi-9 helicopter used on the warships of the Chinese Navy, this helicopter temporarily named Zhi-9X has a pair of long wings, and the ducted tail rotor behind it is missing, replaced by a so-called "vector thrust ducted propeller".

"Chief Master Guo, this wingspan ...... It's about 14 meters, right? It seems that it is still a forward-swept wing? Is the technique mature enough? Major General Zheng, who was in charge of equipment development next to him, looked at the Z-9X, and asked Guo Jingshan, the chief designer of the Z-9X next to Lin Hongfei and the person in charge of the Z-9X verification machine project, in surprise, with a slight worry in his tone.

"The wingspan is 14.7 meters, and the wing sweep angle is 7.6 degrees," Guo Jingshan is full of confidence in the world's second aircraft to use a small forward sweep wing, "We have done rigorous testing of this wing for more than two years, and we can ensure that as long as the flight speed does not exceed 700 kilometers, there will be absolutely no problem with the wing,...... Well, the Z-9X is designed for a maximum speed of 550 km/h. ”

"That's good." Major General Zheng nodded, obviously relieved, indeed, after more than two years of testing, basically any problems should be discovered, and in the future, after the aircraft is put into service, it only needs to be stable in the sky hovering and flying, and it does not need to do high maneuvering maneuvers like armed helicopters and fighters, so that the requirements can be lower. But the next moment, Major General Zheng exclaimed, "Well, you even got the folding wings out?" ”

Wing folding?

With the exclamation of Major General Zheng, the eyes of the generals suddenly looked at the Zhi-9X that was heating up: under the gaze of the generals, the plane was doing the action of folding the wings, and the Zhi-9X was slowly folding the wings that had just been flattened......

Seeing this scene, the generals' mouths all turned O-shaped, and General Wang Xu looked at Lin Hongfei with a shocked face, and was a little incoherent for a while, "Mr. Lin, your steps...... Too fast, right? …… It's just a technical verification machine, and it is necessary to engage in folding wings? ”

Lin Hongfei understood what General Wang Xu meant, folding wings is a unique design of aircraft carrier-based aircraft, in order to put as many aircraft as possible in the limited space on the aircraft carrier, to enhance the aircraft carrier battle group of fighters, carrier-based early warning aircraft will naturally be no exception, but the Z-9X is just a technical verification aircraft, is it necessary to engage in folding wings? The most important thing is that we have never done folding wings before, can we solve the technical problems? Is it okay to have material strength? What about the design of the structure?

Doubting his own technical strength? Is this worth it?!

Without waiting for Lin Hongfei to speak, Guo Jingshan, the chief designer of the Z-9X, had already opened his mouth with a dissatisfied face, "Commander Wang, as a low-speed flying AWACS aircraft powered by vector ducted propellers and rotors, the flight speed of the Z-9X is much lower than that of a fighter, because there is no need to mount weapons under the wing, and its wing load and requirements for wing strength are much smaller than those of the fighter wing. If we can't solve the structural strength problem of this low-demand folding wing, is it worthy of the country's massive capital investment? ”

"I'm sorry, I made a mistake." General Wang Xu was stunned for a moment before he realized what he had done wrong, and immediately apologized to the experts present.

Indeed, as Guo Jingshan said, since there is a variable swept wing technique of the Tu-22M3 "Backfire" fighter for reference, the difficulty of designing a vulgar folding wing with weak wing load is not as great as imagined, and he is only subconsciously frightened by the folding wing technique.

Guo Jingshan didn't expect General Wang Xu to apologize so quickly, but he was a little flattered for a while, and said a little helplessly, "It's okay, I can't blame you ......."

"Okay, let's not talk about this," Lin Hongfei interjected, resolving the embarrassment of the scene, "Folding wings and rotor techniques are what we need, early research is better than late research, huh...... General Wang, the plane is about to take off......"

Wang Xu hurriedly looked over, isn't it, just this talking kung fu, this straight-9X verification aircraft has completed the wing folding process, the original length of nearly 15 meters of wings and rotors after all were folded up and all spread out, just now was "petite and cute" Zhi-9X instantly became huge!

Seeing this incomparably smooth and mellow scene, the admirals nodded secretly in their hearts, and their eyes lit up one by one: just through this simple action, it can be seen that AVIC No. 2 Group's technology in folding wings and folding rotors has been very mature and reliable.

No, not only is it very mature and reliable, but it has even reached a very mature level.

Realizing this, the generals of the Navy were all excited and enthusiastic: if the wings and rotors could be folded, how much space could be saved and how many more planes could be installed on the aircraft carrier in the future!
