Ning Lei, who could be regarded as having seized the opportunity, told Liang Yuan in detail about the Republic's investigation of the Tornado fighter jet.

"Ah, Uncle Ning went to the Federal Republic of Germany in 86, why don't I remember, I would have contacted Mbb if I knew about it. ”

Liang Yuan said casually, COMAC is completely a civil aviation project, even Belfast, which has a great bloodline, and Liang Yuan did not deliberately explore the direction of the military industry, so he really didn't know the origin of Mbb in the military industry field and the Republic.

"It's enough to be wicked, and I won't let people live a year earlier. ”

Tang Wan complained on the side, and everyone laughed.

"The year before, Xiaoyuan was still holding a remote-controlled plane to hang a caterpillar to scare his sister's pocket money, but I can't see any signs of genius. Ning Wanjia also smiled and lifted Liang Yuan's old bottom.

Liang Yuan knew that his changes could not be hidden from Ning Wanjia, and when he heard the girl talk about her bullshit a year before smuggling, she felt a little empty in her heart, and quickly changed the topic.

"There is no suitable reason, and it is not easy to stretch out your hand indiscriminately, Hainan Airlines does not have aircraft carriers, and no one cares about the high-profile nature of carrier-based aircraft, and even if the policy is okay, it is too lazy to spend energy to fight wits and courage with some friendly businessmen. ”

In Liang Yuan's view, the naval force of the Republic is the global tentacle of the Republic to convey its own will, and the underwater nuclear force is the cornerstone of the survival of the Republic.

As for a certain island, the navy alone can solve it after a certain critical point in strength, and if the strength is not enough, even if the three armed forces are together, it will be in vain.

"And then you put all the things of the thousand institutes on Uncle Ning's head?"

"Ning Lei is not me talking about you, changing the change is to change the concept, it is good to have a big boss to invest, it is difficult to send it to your mouth to feed. ”

Tang Wan complained about Ning Lei's attitude.

Ning Lei sighed helplessly, there was really no way to break with Tang Wan, the army and society were not the same thing at all.

"Uncle Ning, anyway, I put the conditions on the table, and I don't understand the design of the aircraft, so Uncle Ning can combine it. ”

"Don't talk about the big cat series, Mbb's titanium alloy wingbox technology I try to buy it, my mom has been improving Spey, the latest version of Spey has increased by seven percent of the thrust, and the afterburner thrust has increased from 98.15KN to 105.15KN~. ”

Spey don't look at the push ratio is low, but the foundation is the foundation of the big push, and the improvement potential is by no means comparable to the newly developed three-meter-long push in Europe.

"The latest Spey experimental push ratio is 6.3, Mom, when will Spey be changed to 7 push ratio, when will Brilliance be able to lie down and make money in China. ”

Speaking of this, Liang Yuan gave a thumbs up and shook it vigorously at his wife, and the thrust of 10515 ~ five figures properly entered the threshold of the big push, which is also the reason why Liang Yuan is not very enthusiastic about the transfer of Rolls Rb119 at present.

If Brilliance Power overcomes the five-meter-long push, the three-meter-long medium-thrust aero engine, the republic's own equipment needs are probably only the next generation of advanced trainers, although Laoba's super Sabre project also has a demand for the push, but Liang Yuan is not sure whether it is worth developing a new pusher for the project of higher education and Laoba.

"With the technology of supercomputing and French M88 engines, it is not difficult for Spey's follow-up model to change to Tubi Seven, but if it continues to change to the number of Tubi eight or Tubi nine stages, it will have to be redeveloped, and tinkering on the original basis will not be successful. ”

"Sister-in-law, when will Speygai, who is pushing seven, be able to mature on the plane?"

"It will take two or three years to change to Tubi Seven, and it will take at least five or six years to change to Tubi Eight, and Tubi Nine may take the next century, and I am not sure if there is more. ”

Li Yuanling casually said the expected progress of Brilliance Power in Spey.

Hearing Li Yuanling's answer, Ning Lei was just very surprised by the research and development speed of Brilliance Power, but Liang Yuan almost burst into tears, if his wife can really solve the aero engine of Tubi Seven, J-11 will not worry about it first, and the power of No. 10 will be solved by the Republic itself.

As for the rest of the Tubi8 and Tubijiu, Liang Yuan didn't know what to say, it was obvious that Liang Yuan had never seen the aero engine modification plan of Tubi8 and Tubijiu on the documents of Brilliance Power, Li Yuanling mentioned this at this time to endorse the four-generation heavy annihilation plan that his son had just come out of.

"Sister-in-law is powerful, and the motivation to quickly reverse ninety-three in the future will count on Hua Chen, even if he is fooled by Xiaoyuan, the trip is worth it just because of the news of his sister-in-law. ”

Ning Lei smiled and stretched out his hands, and shook in the direction of Li Yuanling with joy and sincerity.

Whether Ning Lei or Li Yuanling, as senior industry insiders, know that aero engines are the foundation of aircraft, and no matter how advanced the aircraft is, it is useless.

"Uncle Ning, let me have a bad idea, the 93rd Army can bid for fighter-bombers for the whole system, requiring ultra-low-altitude breakthrough capabilities, supersonic flight capabilities, a maximum bomb load of nine tons, a maximum range of 3,900 kilometers, and a maximum speed of Mach 2.2. ”

The data given by Liang Yuan is a reference to the performance data of the Tornado fighter, if the aircraft intends to achieve this performance data, there are only two ways, either to adopt the design of the variable sweep wing, or the thrust ratio of the aero engine exceeds 8 and it is better to achieve the thrust ratio of 9, and there is no other way.

In terms of performance data, the Republic's J-7 and Tornado fighters are almost the same level of attack aircraft.

The length of the J-7 is 21 meters, and the length of the wind turbine is 16 meters

J-7 wingspan 12.8 meters, Gale wingspan 13.91 meters (unfolded)

The Jianh-7 has an empty weight of 14.5 tons and a Tornado has an empty weight of 13.9 tons

The maximum load of the J-7 is 12.9 tons, and the maximum load of the Tornado is 14.1 tons

The maximum range of the J-7 is 3,650 kilometers, and the maximum range of the Gale is 3,890 kilometers

The maximum speed of the J-7 is Mach 1.6, and the maximum speed of the Wind is Mach 2.2.

The military thrust of the J-7 is 2*55.56KN, and the afterburner thrust is 2*93.05KN.

The military thrust of the wind is 2*43.8KN, and the afterburner thrust is 2*76.8KN.

On the maximum speed of the J-7 is lower than the gale, on the maximum range of the J-7 is also lower than the gale, on the maximum thrust and military thrust of the J-7 is greater than the gale, the only explanation for this situation is that the airfoil of the two sides is completely different, and it is clear at a glance whether the performance of the variable sweep wing is good or not.

Of course, the J-7 can also imitate the fashionable controllable large side strip on the F18 across the Pacific Ocean, which is said to perfectly replace the effect of the swept wing, but the F18 only has a maximum speed of Mach 1.8, which really makes this perfect replacement a bit hehe.

For example, the biggest advantage of the variable swept wing is that when the aircraft engine thrust ratio is 6, the aircraft can obtain the performance data of the engine thrust ratio of 8, and the Grumman is stillborn in the Super Tomcat program, and the aero engine with a thrust ratio of 7.5 is enough to push the Super Big Cat to carry out supersonic cruise.

What is the price paid for the F22 that is said to be able to get a low-speed, subsonic, and supersonic universal airfoil for supersonic cruise, and the thrust ratio of the aero engine is 10+.

There are two bases for the elimination of overseas variable swept wings, the aero engine thrust ratio directly exploded to 10+, and the atmospheric friction heat caused great damage to the aircraft structure when the speed of sound above M2.5.

In other words, with a 10+ push ratio of the aviation engine, the brick can also fly below M2.5, the area of the earth is not large, of course, the airfoil can be done casually, and when the speed exceeds M2.5 or above, the structural material of the aircraft has to be changed from aluminum alloy to stainless steel, once the main material of the aircraft is changed from aluminum alloy to stainless steel, the aero engine of the air superiority fighter type aircraft with 10+ push ratio is not enough, at least 30+ push ratio is enough.

If we ignore the pitifully short lifespan of human beings, from the perspective of the variable swept wing of the bar essence attribute, the aviation materials are backward, the aero engine thrust ratio is backward, and it is also true that Lao Tzu cannot be supported to fly faster.

The long-term perspective of scientific and technological development changes the relationship between swept wings, aviation materials, and aero engine thrust ratios, no matter which one is said to be backward, it is very appropriate to use spiral ascension.

Of course, as far as the aircraft carrier carrier-based aircraft is concerned, the excellent low-speed performance of the variable sweep wing can defeat all dissatisfaction, and other airfoils are useless even if they are converted into bar fine attributes.

Brilliance Power is willing to spend money, and there is a genius chief engineer like Li Yuanling, it will take five or six years for the aero engine of the push-ratio 8 to roll off the assembly line, and it will take the next century to push the ratio 9 well, Liang Yuancai does not believe that other power suppliers in the republic will inexplicably explode, and make the push-ratio 8-level aero engine before Brilliance.

The way of the engine does not work, and there is only one left to participate in the bidding for the fast anti-93 equipment, of course, if the big factories in the north can explode to get Maozi in advance, Liang Yuan will also be willing to admit the localization of the Su-30 and the like.

Although Gangji has caught up with the tail of the international chip industry, it can be said that it knows nothing about the military industry, and Gangji is currently developing in the four fields of supercomputing, communications, general CUP, and process technology, and it is extremely thirsty for talents and funds, and has no energy to enter the military industry at all.

The replacement of chips in the military industry is far less rapid and fierce than that of the civilian industry, and if the gang-based collector is distracted, it will only slow down its own development pace, so in Liang Yuan's planning, the gang-based collector can only provide safe basic chips, basic communication networks and other products for the military industry, as for how to use the chip, professionals in the military field must be developed and designed.

At present, the strongest institution in the republic around chip design is the Hong Kong-based power collector itself, under the siphon effect of giant enterprises, the kind of outstanding talents who can start from basic development have been dug by Liang Yuan and invested in the most fierce civilian competition, which directly leads to the fact that there are few top talents in the military industry who can take the lead in Nie Xiaotian and Wang Xin to undertake the research and development of the entire chip application system.

It is impossible for Liang Yuan to put Wang Xin and Nie Xiaotian into the avionics localization project of the F14 fighter, so a mature technology platform can be redeveloped on this basis to reduce the difficulty of research and development exponentially.

Grummen couldn't count on it, and Hurricane became one of Liang Yuan's choices, but Liang Yuan didn't expect that there was a story between Ning Lei and Tempest Fighter.

Although Liang Yuan said it piecemeal, but after dealing with Liang Yuan for so long, Ning Lei also vaguely guessed what Liang Yuan meant, the difficulty of holding the F14 by the Republic itself is too high, and the introduction of the Tornado fighter platform from overseas will be much easier compared to European technology in the F14, at least the most headache wing box problem is not an obstacle.

Although Ning Lei couldn't guess where Liang Yuan's confidence came from, he also vaguely guessed that the F14 localization project itself may just be a technical verification carried out by Liang Yuan for the fourth generation of heavy annihilation, in other words, even if the F14 localization is successful, the possibility of mass production of equipment is not large.

However, once the research and development of the fourth-generation heavy annihilation is stuck, the localized F14 can be on top of the pit, which is completely in line with the style of Liang Duopit and multiple spare tires, no matter how Ning Lei looks at it, he feels that the fourth-generation heavy annihilation is the ultimate goal of Liang Yuan.

"Xiaoyuan's this is not a bad idea, directly copycat F14 Xiaoyuan is afraid of attracting the attention of the other side of the Pacific Ocean in advance, after all, I see that Yuanjia's development plan in recent years is not able to bypass the market, through the wind platform to learn technology, small-scale production of F14 verification technology, and finally directly batch four generations of heavy annihilation is Xiaoyuan's hidden thoughts. ”

"The F14 fighters that the Navy and Air Force are now equipped with are not in the mind of running away, once the F14 is successfully localized in the future, it will be directly replaced one by one~"

Ning Lei smiled and directly exposed Liang Yuan's unspoken little abacus.
