"In addition to the improvement of the power system, what are the improvements of this aircraft?" Listening to Wang Xiaodong's nonsense about the reason for retaining the navigator's cabin, Chen Geng asked.

"Mainly the fuselage and wings," Wang Xiaodong said: "According to your suggestion of 'laying the foundation first' at that time, we enlarged the fuselage by 26%, increased the wing area by 32%, and in order to meet the requirements of the hardpoint, the length of the wing was lengthened by 2.8 meters.

In addition, we have designed a total of six underwing hardpoints and two wingtip hardpoints, of which these two hardpoints near the fuselage have been specially strengthened, which can be hung in the form of composite pylons on two air-to-ground -63 missiles, and the other four hardpoints can be hung on one air-to-ground -63 missile......"

Chen Geng nodded frequently when he listened, and had a general impression of the performance of this technical verification machine: the foundation has been laid.

Although limited to the level of electronic technology, the overall combat effectiveness of this H6 technology verification aircraft is much worse than that of the K version of H6 a few years later, but the foundation is much better than the K version of H6. There will be a step-by-step leap in the amount of weapons carried, and the deterrence capability of the opponent will also be multiplied.

Of course, this is a good thing, but Chen Geng found a bad problem: why did the engineers and technicians around this "technical verification machine" not look surprised at all by the arrival of his "outsider"?

When he asked Wang Xiaodong this question, Wang Xiaodong laughed: "Mr. Chen, this project was proposed by you, and it also received strong support from your COMAC during the period.

Chen Geng was dumbfounded.

But if you think about it, too!

What time is it?

It is the honeymoon period between the East and the West, and it is the famous "model of peace" period, during this period, the West can even sell the F14 and F16 fighters to us (we can't afford it is another matter), we can even send our own J8 to the United States, ask the Americans to help improve it, and ask Chen Geng to visit a static, but also because of Chen Geng's proposal to get started, and during the period of the technical verification aircraft with the strong support of the COMAC Group, is there anything incomprehensible?

"We have flown several sorties of this demonstration aircraft, and the test pilots have a high evaluation of this aircraft, but now we are a little worried, and the above does not seem to be too interested in formally establishing and developing this type of aircraft," Wang Xiaodong said with some worry: "If we spend so much money and so much energy to build this aircraft, and finally cannot officially establish the project, we will waste all the time, energy and funds we spent during this time." ”

Wang Xiaodong has such worries, but Chen Geng is full of confidence in the future of this technology verification machine, and after the Gulf War in 1991, the Americans have shown the world that the B-52 has fallen behind in the eyes of China to adapt to the times. Only after the new use of the things that are buried in the cemetery, everyone suddenly reacted to the fact that there is no absolutely advanced weapon, and there is no absolutely backward weapon, even if it is a backward weapon, if its potential is fully explored, not only can this weapon regain its livelihood, but can even become a killer heavyweight equipment, such as H6, the medium-range bomber that the Soviet Union has eliminated, was changed by us into a quasi-strategic bombing capability. A large airborne precision strike platform that can remotely launch guided weapons outside the enemy's defense zone.

What's even more powerful is that the N version after the K version not only strengthens the electronic warfare and electromagnetic suppression capabilities on the basis of the K version, but also has the ability to refuel in the air, so that this aircraft, which previously only had a "quasi-strategic" range, has a real strategic-level range.

He patted Wang Xiaodong on the shoulder and said, "You don't have to worry about this, even if it's to sell a few more engines, I will definitely help you Xifei speak...... Speaking of which, has the above clearly expressed its opposition to the establishment of this aircraft project?"

"That's not true," Wang Xiaodong said: "The above just thinks that this aircraft is more expensive, almost 70% more expensive than the ordinary H6 using two turbojet-8s, and some leaders mean that if you buy two of these aircraft, you can sell three ordinary H6s." ”

Chen Geng was speechless for a while: "If we calculate according to this account, why should we develop precision strike weapons such as missiles, and directly use artillery to bombard more trouble? No, the artillery is too advanced, and we can directly take knives, guns, and sticks to cut them down." ”

Wang Xiaodong smiled wryly and didn't speak: Some words, some complaints, Chen Geng can say, he can't say.

Chen Geng didn't mean to continue to complain, and after complaining a few words, he continued to ask: "Didn't you carefully settle accounts for these opposing leaders?"

"It's a matter of forgetting, but it's ......," Wang Xiaodong euphemistically explained to Chen Geng: "Well, the leaders also have their own set of ideas. ”

I see!

To put it bluntly, it is not that individual comrades do not know that if this aircraft can be finalized, the improvement of our army's combat effectiveness and strategic significance, but in this way, they are making their voices heard and expressing their existence - this situation is too normal.

"Then take your time, don't be in a hurry, anyway, it will take a long time for this plane to complete the finalization work," Chen Geng comforted Wang Xiaodong and said: "Then how about the comrades of the Air Force about this plane? Are you interested?"

Speaking of this, Wang Xiaodong was a little proud: "The leaders of the Air Force have come several times just to see this aircraft, except that they are a little dissatisfied with the engine layout of this aircraft and feel that it is too capitalist, the overall evaluation is still good." ”

It can be seen from Wang Xiaodong's slightly arrogant reaction that he actually didn't take the opposition of individual comrades too seriously.

"Then what else is there to worry about?" Chen Geng immediately relieved his heart: "As long as the comrades of the Air Force are interested...... Will it be possible to complete the test flight within three years?"

Wang Xiaodong: "If the funding can be guaranteed, it should be about the same." ”

Chen Geng knew in his heart: As long as this H6 technology verification machine can last for three years, three years later, as soon as the Gulf War breaks out and ends, and when the time comes to see the performance of the B52 in the war under modern high-tech conditions, even if Xifei wants to dismount this plane, it will be impossible for him: give you money! You must give Lao Tzu this plane up!

It was Wang Xiaodong who couldn't help but complain about Chen Geng: "Mr. Chen, when did you start working on that 90,000 Nn thrust engine?"

The "magic change" technical route of COMAC's "tay" MK650 series engine was not deliberately announced, but it was not deliberately hidden, Wang Xiaodong has always been a person who knows this "magic change" technical route, which Chen Geng knows, but this guy's complaint at this time still makes Chen Geng very curious.

"After knowing the fuel consumption of your MK650 engine, the comrades of the Air Force have always wanted to replace the current turbojet-8 with a turbofan, but the thrust of the engine is too bad," Speaking of this, Wang Xiaodong couldn't help but complain: "The comrades of the Air Force are embarrassed to look for you, so they are nagging in my ear, and I don't know how many times I have told me." ”

Chen Geng laughed when he heard this: "Then you let them come to me...... Having said that, we haven't even fully mastered the MK650-8C of the basic version we have introduced, and if we want a 90 kN engine, we will have to wait at least another seven or eight years. ”

It is also helpless to say, since the first batch of "tay" MK650-8C data began to be handed over, several years have passed, but limited by the restrictions of the domestic precision processing industry and material industry, the localization rate of the "tay" 650-8C engine of COMAC Group is still less than 100%, and almost 8% of the materials and blanks need to be imported from Rolls-Royce Even if everything goes well, it will take about 2 years.

Some people may ask, Rolls-Royce has been teaching you hand-in-hand and dedicatedly, for several years, why can't you? Are you not learning hard or are you stupid?

This is really not a question of stupidity or not, there must always be a step-by-step process of learning and mastering - rolling skin, making dumplings seems very simple, right? It seems to be nothing more than a very simple pinch, a pinch, but you ask those students who can make dumplings, how long did it take them to learn to make a beautiful dumpling from the beginning?

Wang Xiaodong smiled and shook his head, some words he couldn't explain too much, after all, Chen Geng's identity was still a little sensitive, so he changed the topic and asked Chen Geng: "By the way, what's going on with the American boss who came with you?"

"Are you talking about Mr. Robinson?" Chen Geng said in surprise, "What's wrong with him?"

Wang Xiaodong said with a smile: "It's not a big deal, it's just that many comrades are avoiding this Mr. Robinson during this time." ”

I see!

Because of Frank Robinson's perseverance in wanting to open up the general aviation market in China, some comrades really couldn't stand it, but this Frank Robinson was not only a very rich foreign guest, but also a friend of Chen Geng.

After knowing that Chen Geng was going to fly west, some comrades who were annoyed by Frank Robinson could not come directly to themselves, so they simply paid attention to Wang Xiaodong's head: Comrade Xiaodong, can you talk to Mr. Chen Geng, and let Mr. Chen persuade his American friend to stop tossing, it is impossible for us to open the general aviation market and the airspace below 3,000 meters.

What else can Chen Geng do?

Of course, the only way to do that was to promise to go back and persuade Frank Robinson.

But Wang Xiaodong, because of this, couldn't help but be a little curious about the general aviation market in the United States: "Mr. Chen, I heard that many Americans have private jets, and the airspace in the United States is open to private individuals, is it true?"

"The United States will be 3000 meters below the airspace for general aviation airspace, and open to all general aviation aircraft," Chen Geng shook his head and said: "However, although the United States will be 3000 meters below the general aviation airspace, but it is not unconditional, unrestricted open, such as medium-sized, large airports near how many kilometers of the airspace, in order to ensure the normal take-off and landing of civil aircraft, will not be open to general aviation, want to go in need to apply in advance, of course, the application process is very simple, The approval process is also very fast, basically to get in touch with the tower, and then the tower will give you a reply - all civil aircraft in the United States are forced to install an automatic answering machine when leaving the factory, as long as the aircraft flies together, even if it is an ultra-low altitude flight, the automatic answering machine will be activated, and will automatically get in touch with the nearby air traffic control agency, and the registration code, heading, speed and other information of your aircraft will automatically appear on the computer of the nearby air traffic control agency;

For example, some sensitive military and political settings will also be set up near the no-fly zone for general aviation, but in general, the vast majority of the airspace in the United States is open to general aviation, as long as you fly at an altitude below 3000 meters, you basically fly how you want. ”

"This is as it should be, the airspace near the airport and near the military base must not be casually passed, otherwise what if a foreign spy takes a plane to take a photo?" Wang Xiaodong nodded frequently when he listened, feeling eye-opening, and looking forward to what Chen Geng was going to say next.

"As for private jets," Chen said, "according to the statistics of the Federal Aviation Administration in 1985, in the United States, the number of people with civil aviation pilot licenses is about 650,000, if you exclude commercial licenses, civil airline scheduled flight pilot licenses and pilot student licenses, the number of people with fixed-wing aircraft private pilot licenses is about 220,000, if you add sports and leisure pilot licenses, rotorcraft and glider pilot licenses, the total number should be 280,000."

Of course, having a private jet license does not mean that there is a private jet, counting the jet business jets owned by large companies and large groups, the number of private jets in the United States is about 200,000. ”

"200,000 private jets?!280,000 people have private pilot's licenses?!" Wang Xiaodong's surprised eyes were about to fall out: "No wonder your commercial aircraft have exported a lot of Yun-11 and Yun-12 to the United States in recent years!"

Since Chen Geng began to use the Yun 11 to reward dealers, COMAC has maintained the "tradition" of exporting Yun 12 transport aircraft to the United States every year in recent years, creating a large amount of foreign exchange for Huaxia, although these planes are "internally digested" through Chen Geng's own channels, but no matter how these planes are sold, the aircraft is finally sold to the United States, and the country's exports are earning foreign exchange, right?

The eyes of several major domestic aviation manufacturing groups are red and red.
