    Ning Lei, who had finally caught the opportunity, told Liang Yuan everything about the Republic's inspection of Tornado fighter jets.

    "Ah, why don't I remember that Uncle Ning went to the Federal Republic of Germany in 1986? If I had known about this, I would have contacted Mbb a long time ago."

    Liang Yuan casually said that COMAC is entirely a civil aviation project, even for Belfast, which has a Universiade pedigree. Liang Yuan did not deliberately inquire about the military industry, so he really didn¡¯t know what Mbb¡¯s role in the military industry and the Republic was.  origin between.

    "This is already evil enough. If it had been a year earlier, it would not have allowed anyone to live."

    Logan complained on the side, and everyone laughed.

    "The year before, Xiao Yuan used a remote control plane to hang caterpillars to scare his sister's pocket money, but there was no sign of any genius." Ning Wanjia also smiled and exposed Liang Yuan's background.

    Liang Yuan knew that his changes could not be hidden from Ning Wanjia. Hearing the girl talk about his messy things the year before smuggling, he felt a little guilty and quickly changed the subject.

    "There is no suitable reason for Qiansuo to reach out randomly. Hainan Airlines does not have an aircraft carrier. No one in Qiansuo takes care of the carrier-based aircraft no matter how high-profile it is. If it were other things, even if the policy is fine, it would be too lazy to spend energy and some  Friends and businessmen compete with each other in a battle of wits and courage.¡±

    In Liang Yuan's view, the Republic's naval power is the global tentacle for the Republic to convey its will. Underwater nuclear power is the cornerstone of the Republic's survival. The other Air Force and Army are not used in many places except for nuclear wars, so there is no need for him to go out of his way to do so.  Its cheating.

    As for a certain island, if the strength exceeds a certain critical point, the navy can solve it alone. If the strength is not enough, even the three armies will be in vain.

    "Then you blame Uncle Ning for everything that happened in Qiansuo?"

    "Ning Lei, I'm not telling you. The purpose of reforming the reform is to change the concept. It would be good if a big boss invests. Is it possible that I have to feed it to you?"

    Tang Wan complained about Ning Lei's attitude.

    Ning Lei let out a helpless sigh. There was no way he could tell Tang Wan that the army and society were not the same thing at all.

    "Uncle Ning, I have put the conditions on the table anyway, and I don't understand the aircraft design, so Uncle Ning can just put it together."

    "I won't talk about the Big Cat series. I'm trying to buy Mbb's titanium alloy wing box technology. My mother has been improving the Spey. The latest version of the Spey has increased thrust by 7%.  The thrust force has increased from 98.15KN to 105.15KN~."

    Although Sibei¡¯s push ratio is low, the foundation is that of a big push, and the improvement potential is by no means comparable to the three-meter-long medium push newly developed in Europe.

    "The latest Sibei experimental model has a push ratio of 6.3. Mom, when will the Sibei be changed to a push ratio of 7? When will Brilliance be able to make money in China?"

    Speaking of this, Liang Yuan gave a thumbs up and shook it vigorously at his mother. The five-digit push force of 10515 has fully entered the threshold of big push. This is also the reason why Liang Yuan is not very enthusiastic about the transfer of Luo Luo Rb119.  .

    If Brilliance Dynamics overcomes the five-meter-length major thrust and the three-meter-length medium-thrust aeroengine, the Republic¡¯s own equipment needs will probably only be the next-generation advanced trainer aircraft, although Laoba¡¯s Super Saber project also has demand for medium-thrust aero engines.  , but Liang Yuan is not sure whether it is worthwhile to develop a new Chinese model for the project of higher education and Laoba.

    "With the technology of supercomputing and the French M88 engine, it is not difficult to change subsequent models of Spey to push ratio seven. However, if we continue to change to push ratio eight or nine, we will have to develop it again. On the original basis  Tinkering won¡¯t work.¡±

    "Sister-in-law, when will Sibei Kai, who pushed Bi Qi, mature and start using the machine?"

    "It will take two or three years to change to Tuibi 7, at least five or six years to change to Tuibi 8, and it may take the next century to change to Tuibi 9. If it takes more than that, I'm not sure."

    Li Yuanling casually talked about Brilliance Power¡¯s expected progress in SPEI reform.

    Hearing Li Yuanling's answer, Ning Lei was just very surprised by Brilliance Power's research and development speed, but Liang Yuan almost burst into tears. If my mother could really solve the aeroengine of the Push-7, she wouldn't have to worry about the J-11. I'm afraid the power of the 10 would be  The Republic can handle it on its own.

    As for the remaining Tuibi 8 and Tuibi 9, Liang Yuan doesn¡¯t know what to say. It¡¯s obvious that Liang Yuan has never seen the aero engine modifications of Tuibi 8 and Tuibi 9 in Brilliance Power¡¯s documents.  Plan, when Li Yuanling mentioned this at this time, he was endorsing the fourth-generation annihilation plan that his son had just emerged from.

    "My sister-in-law is awesome. I will rely on Hua Chen for the motivation to fight against the odds in the future. Even if I am deceived by Xiaoyuan, the news about my sister-in-law alone will make this trip worth it."

    Ning Lei smiled and stretched out his hands, shaking them in the direction of Li Yuanling with sincerity.It shook again.

    Both Ning Lei and Li Yuanling, as senior industry insiders, know that aviation engines are the foundation of aircraft. Without engines, no matter how advanced the aircraft is, it is useless.

    "Uncle Ning, I have a bad idea. The 93rd Army can invite bids for fighter-bombers from the whole system. They are required to have 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 using a variable swept wing design, or the thrust ratio of the aircraft engine exceeds 8, preferably reaching a thrust ratio of  9. There is no other way.

    From the analysis of performance data, the Republic's JH-7 and Tornado fighter jets are almost the same level of attack aircraft.

    The length of JH-7 is 21 meters and the length of Kuangfeng is 16 meters

    The wingspan of JH-7 is 12.8 meters, and the wingspan of Guangfeng is 13.91 meters (in unfolded state)

    The JH-7 weighs 14.5 tons when empty, and the Guangfeng weighs 13.9 tons when empty

    The maximum load capacity of JH-7 is 12.9 tons, and the maximum load capacity of Guangfeng is 14.1 tons

    The maximum range of JH7 is 3650 kilometers, and the maximum range of Guangfeng is 3890 kilometers

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

    The J-H7 military thrust is 2*55.56KN, and the afterburner thrust is 2*93.05KN.

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

    In terms of maximum speed, the J-H-7 is lower than the violent wind. In terms of maximum range, the J-H-7 is also lower than the violent wind. In terms of maximum thrust and military thrust, the J-H-7 is greater than the violent wind. The only explanation for this is that the airfoils of both sides are completely different.  It is obvious at a glance whether the performance of the variable swept wing is good or not.

    Of course, the JH-7 can also imitate the fashionable controllable large side strips on the F18 across the Pacific. It is said that this thing can perfectly replace the effect of variable swept wings, but the F18's maximum speed of only Mach 1.8 makes this perfect replacement a bit awkward.

    For example, the biggest advantage of changing the swept wing is that when the aircraft engine thrust ratio is 6, the aircraft can obtain performance data of an engine thrust ratio of 8. Grumman's stillborn Super Tomcat project has an aviation thrust ratio of 7.5.  The engine is enough to propel the Super Cat to supersonic cruise.

    What is the cost of the F22 universal airfoil that is said to be able to handle low speed, subsonic speed, and supersonic speed when performing supersonic cruise? The thrust ratio of the aero engine is 10+.

    There are two reasons for the elimination of overseas variable-sweep wings. The thrust ratio of aero-engines directly explodes to 10+. At the speed of sound above M2.5, atmospheric friction heat causes huge damage to the aircraft structure.

    In other words, with an aircraft engine with a thrust ratio of 10+, the brick can fly below M2.5. The area of ??the earth is not that big. Of course, the airfoil shape can be modified casually. When the speed exceeds M2.5 and above, the structure of the aircraft  The material 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 10+ thrust ratio aeroengine of an air superiority fighter type aircraft will not be enough. At least a 30+ thrust ratio is enough.  .

    "If we ignore the pitifully short lifespan of human beings, from the perspective of the variable-sweep wing with its excellent attributes, it is also true that the aviation materials are backward and the thrust ratio of the aero-engine is backward, so it cannot support me to fly faster.

    From the long-term perspective of scientific and technological development, the relationship between swept wings, aviation materials, and aero-engine thrust ratios, no matter which one is used to describe it, is inappropriate, but spiraling is very appropriate.

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

    Brilliance Dynamics is willing to spend money and has a talented chief engineer like Li Yuanling. It will take five or six years for the aero engine to push the Bi8 off the production line. It might not be possible until the next century to push the Bi9. Liang Yuancai does not believe in the Republic.  Other power suppliers will explode inexplicably and come up with an aero engine that can push 8 levels before Brilliance.

    There is no way to go about the engine. The only one left to participate in the bidding for the quick response ninety-three equipment is to change the swept wing. Of course, if the big manufacturers in the north can explode and handle Maozi, Liang Yuan will also be willing to localize the Su-30 and the like.  Admit defeat.

    Although Hong Kong Base Electric has caught up with the tail of the international chip industry, it can be said that it knows nothing about the military industry. Hong Kong Base Electric is currently developing in the four fields of supercomputing, communications, general cup, and process technology, and it is extremely thirsty for it.  Talents and funds, there is no energy to enter the military industry.

    The chip replacement in the military industry is far less rapid and intense than that in the civilian industry. If Hong Kong-based power collection is distracted, it will only slow down its own development pace. Therefore, in Liang Yuan¡¯s plan, Hong Kong-based power collection can only provide security for the military industry.  Basic chips, basic communication networks and other products, as for how to use the chips, they need to be developed and designed by professionals in the military industry.

    At present, the institution with the strongest chip design capabilities in the Republic is Hong Kong-based Power Collection itself. In the giant enterprise HongAs a result, outstanding talents who can start from basic development have been poached by Liang Yuan and invested in the most fierce civilian competition field. This directly leads to the fact that there are few Nie Xiaotian and Wang Xin who can take the lead in the military industry.  Top talents are responsible for the research and development of the entire chip application system.

    It is impossible for Liang Yuan to invest experts of Wang Xin and Nie Xiaotian's level into the F14 fighter's avionics localization project, so building a mature technology platform and re-developing it on this basis can exponentially reduce the difficulty of research and development. After all,  The kind of research and development carried out by Hong Kong-based power collectors belongs to pioneers, and the difficulty of copycatting by followers will be reduced exponentially.

    Grumman couldn't count on it, so Guangfeng became one of Liang Yuan's choices, but Liang Yuan didn't expect that there was a past story between Ning Lei and the Guangfeng fighter.

    Although Liang Yuan spoke in fragments, Ning Lei had vaguely guessed what Liang Yuan meant after having dealt with him for so long. It was too difficult for the Republic to suppress the F14 itself. It introduced the Tornado fighter platform from overseas. With this basic comparison,  With European technology, it will be much easier to suppress the F14. At least the most troublesome wing box problem is no longer an obstacle.

    The f14 localization project and the fourth generation heavy annihilation project were carried out simultaneously. Although Ning Lei couldn't guess where Liang Yuan's confidence came from, he also vaguely guessed that the f14 localization project itself might just be carried out by Liang Yuan for the fourth generation heavy annihilation.  It is just a technical verification. In other words, even if the localization of F14 is successful, the possibility of mass production of equipment is probably not high.

    However, once the development of the fourth-generation heavy annihilation is stuck, the domestically produced F14 can take over the pit. This is completely in line with Liang Duo¡¯s work style of pitting multiple spare tires. No matter how Ning Lei looks at it, he feels that the fourth-generation heavy annihilation is Liang Yuan¡¯s ultimate goal.  .

    "Xiaoyuan's idea is not a bad idea. Xiaoyuan directly imitates the F14. Xiaoyuan is afraid of attracting the attention of the other side of the Pacific Ocean in advance. After all, I think Yuanjia's development plan in recent years cannot bypass the market. It will learn technology through the wind platform and produce in small quantities.  f14 verification technology, and finally directly annihilating the fourth generation in batches is Xiaoyuan¡¯s hidden intention.¡±

    "Has Xiaoyuan thought about changing the number of F14 fighter jets currently equipped by the Navy and Air Force? Once the F14 is successfully domestically produced in the future, he will directly replace them one by one~"

    Ning Lei laughed and exposed Liang Yuan's unspoken plans.
