readx; The key to jet aircraft lies in turbojet engine technology, and this turbojet engine, the British side is slightly worse, they have not been able to solve the key technology of axial turbojet engines, resulting in the research and development progress of jet engines far behind China and Germany, and Germany is very fast, their jet engine technology is actually suitable for China to develop together, and it is a joint research and development project like liquid-cooled engines. As a result, the FL39 engine of Föhler Aviation and the Yumo 109-004 engine of the German Junkers company have a common technical source, and the two are also similar.

During the thirties, in order to develop the aero engine industry, China took out a lot of advanced goods to carry out military cooperation with Germany, and in the process of rebuilding the German navy, the shadow of Chinese technology existed in the design of the fuselage of new aircraft. Similar military-technical cooperation exists in all walks of life, and it is not even only with Germany, but with Italy, France, Great Britain, Germany, and the United States. In recent years, although all countries have the idea of technological secrecy, but the concept of trade freedom is still very deeply rooted in the hearts of the people, before World War II, there was no country to carry out a technological blockade against China, and the global technology blockade began to be implemented after the outbreak of World War II.

The jet engine developed jointly with China is also developing rapidly in Germany, and the P1065 program for their twin-engine jet has already begun to be implemented, and is currently undergoing initial development and prototype construction, about two to three years later than the practical application of the Chinese jet military aircraft. The reason why China's jet progress is faster is not because China's technology is better than Germany's, but because the Chinese Air Force has invested more resources.

To put it simply, it is more important than the Germans to the development of jet aircraft, and the importance means more resource investment, faster research and development, and faster service speed.

Today, the world's aviation technology is changing day by day, the Chinese Air Force has spent a huge price in order to maintain its technological leadership, when it crossed from the era of air-cooled engines to liquid-cooled engines, the Air Force found that its liquid-cooled engine level was limited, although it occupied a certain advantage in the design of the airframe, but during the war, Britain and the United States could use a lot of resources to catch up with the pace of the Chinese Air Force in a short time, that is to say, the liquid-cooled engine could not bring the decisive advantage to the Chinese Air Force. In order to further expand and consolidate its leading position, the Air Force has invested significant resources in the field of jet engines, trying to rely on jet engines to re-establish an era's lead, and hope to maintain that lead for at least five years or more.

When Chen Jingyun heard that the Air Force had said that it had also carried out the test of the swept wing, he also put his heart down, and originally he planned to remind the people who reminded the Air Force to let them use the swept wing design, but he didn't expect them to be ready to do it without reminding themselves. This made Chen Jingyun very satisfied with the Air Force.

In the development of the navy, land and air force, especially in the development of military equipment, Chen Jingyun often put forward some of his own ideas and requirements, and then let the military people do it in detail, but many times there is no need for Chen Jingyun to say, the military people first found the problem and put forward a solution, in fact, China's first aircraft carrier, the Taishan modified aircraft carrier, is not Chen Jingyun's meaning, but the group of people in the navy who saw the potential of the aircraft to get out, Chen Jingyun only put forward some ideas of his own in the later construction of formal aircraft carriers.

The Air Force is similar, the research and development of liquid-cooled engines and jet engines was actually not Chen Jingyun's reminder at the beginning, but it was reported to Chen Jingyun after the Air Force started it, and Chen Jingyun would know. Of course, there are also some things that Chen Jingyun personally gave instructions to do, such as radar projects, such as air defense radio-activated bombs on the navy's side, and nuclear bombs and missile projects.

However, on the whole, there are still many projects independently developed by the military, and Chen Jingyun is just an embellishment.

"Is there a big problem with the mass production of this aircraft, and what is the cost?" Chen Jingyun in addition to caring about the surname of the aircraft, he is more concerned about the production and price of these aircraft, only can be mass-produced, the price is cheap, then this aircraft has the surname of actual combat, or it is an expensive and rare toy, does not have actual combat value.

Lieutenant General Lin Feiyang said: "There is no problem in mass production, and Guang'an Aircraft Company and Föhler Airlines can devote themselves to mass production of engines and airframes at any time. Price, this depends on the total amount of procurement, early small batch procurement due to the average share of R & D costs are relatively high, the unit price is expected to be about 200,000 yuan, if the purchase volume can exceed 100 aircraft, then the unit price is expected to be achieved within 150,000 yuan, if the number of purchases exceeds 500 aircraft, then the purchase price will be further reduced to about 130,000 yuan. ”

Chen Jingyun frowned slightly when he heard this: "In this case, even after mass production, the price of an F10 fighter will be more than three times that of an F5 fighter?" ”

As a new generation of main fighters of the Chinese Air Force, the F5 fighter after mass production is actually very cheap, the unit price is only about 50,000 yuan, converted into US dollars is only 20,000 US dollars, which is a very cheap kind in the world, and this group is because the production of F5 fighters is very high, resulting in a significant reduction in the cost of production. If the F10 fighter wants to control the price within 100,000 yuan, then the number of mass production must be at least more than 1,000 units.

"For high-tech equipment, the less the output, the more expensive, the more cheap!" Lin Feiyang seemed to have expected Chen Jingyun's reaction, and immediately explained: "However, if it can be formally finalized, then the number of air force equipment will not be less than 1,000, so that the unit price can be accepted evenly, and the subsequent improvement and research and development of jet aircraft can also greatly reduce costs!" ”

If the Air Force wants to equip jet fighters now, then the cost is very expensive, and this is also a matter of no way, when the F5 fighter began to be produced in small batches, the price was also very expensive, sometimes the price of this thing can not be counted only one batch, but multiple batches must be combined together to calculate, otherwise you will find the same weapon, the price difference before and after is very large.

Chen Jingyun's frown does not mean that he is opposed to equipping jet planes, but if the price is so expensive, the funding problem is not easy to solve, and now the air force itself has no money, and if you want to equip the air force with jet aircraft, you have to give the air force an additional amount of funds, and where this money is misappropriated is also a problem.

Moreover, the early jet fighters in Chen Jingyun's memory should have been single-seat, single-engine swept wings, such as the American F86 fighter during the Korean War and the Soviet Union's MiG-15 fighter, so it also created such an illusion for Chen Jingyun, that is, the jet fighter has the basis of the main force of the Air Force after reaching the level of F86 or MiG-15. And now the X10A jet fighter in front of him is actually more like an early test for Chen Jingyun, used to accumulate experience.

Therefore, in my heart, I am also reluctant to equip these twin-engine jet fighters on a large scale.

Seeing that Chen Jingyun fell into deep thought, Lin Feiyang didn't dare to talk nonsense, for fear that Chen Jingyun would accidentally shoot the X10 project.

On the other side, the general manager of Chuzhou Aircraft Company looked sad, but at this time, Guan Shijie of the Navy came over.

"Manager Fan, the flight show just now was very exciting!" Guan Shijie first praised it, and then said: "I don't know if your company is interested in the project of jet carrier-based aircraft!" ”

As the so-called gains and losses, Manager Fan now has this mood, before coming to Nanjing, he was full of confidence to win the bidding, but Guang'an Aircraft Company got a little trick, using aerobatics to attract Chen Jingyun's attention, and now Chen Jingyun has discussed with the Air Force about mass production and cost control, and this almost means that the X10B designed by Chuzhou Aircraft Company almost missed the Air Force's jet fighter project.

However, now Guan Shijie's words made Manager Fan's eyes shine, if the Air Force can't do it, then look for the Navy! The number of carrier-based fighters in the Navy is no less than that of the Air Force, and the competition is still small.

Since the Air Force's massive shift to liquid-cooled engines, the Navy and Air Force have also chosen different models, which has forced the Chinese Navy to invest a lot of money in the research and development of new aircraft, and the F8 fighter jet is a typical example. However, this does not mean that the Navy has to invest a lot of money and technology, because the naval aviation is very conservative in the bidding for carrier-based aircraft, and often takes the initiative to require the use of mature technology, which is different from the Air Force's penchant for innovation and use a large number of new technologies, and in this way, it almost means that the Navy's aircraft can use many of the results of the Air Force's funded research and development instead of allocating a large amount of research and development funds.

And now Guan Shijie found Chuzhou Aircraft Company is almost the same idea, you must know that before today, there was no research and development project of jet carrier-based aircraft in the navy, and now, Guan Shijie sees that the jet aircraft of the Air Force have been almost done, and the jet engine that the Air Force has invested heavily in research and development is also mature, so he is thinking of picking peaches directly, and he can equip the Navy with new jet fighters without spending so much money, which is not a good thing.

And Chuzhou Aircraft Company is worried about what to do after the development of jet aircraft fails, so the Navy and Chuzhou Aircraft Company are so-called hit it off, and immediately these two people just stepped aside, and then talked softly.

"However, unlike the countrymen in our Navy and Air Force, our requirements for jet carrier-based aircraft will be higher, and we require the take-off speed and take-off distance to be reduced as low as possible, at least the two test aircraft in the X10 project will definitely not be able to take off and land on our Navy's aircraft carriers. And it is better to be a single-engine fighter, so that maintenance and maneuverability can also be better solved! ”
