 "On the contrary, the reason I don't choose this option is that it changes too much."
 Chang Haonan's words made Zhang Man's smile freeze on his face.
 "Remember what I just said? It needs to be based on existing mature technology. Although this enlarged version of the solution does not seem to change much in appearance, if it is implemented in manufacturing, the entire body will have to change, and a stronger aero engine will be needed. , this is not in line with our principles."
 Zhou Shuwan's face next to him finally looked a little better. He didn't care much about his idea being rejected, but he was just worried that Chang Haonan really misunderstood him.
 "After all, we have received some professional training. When we see a design drawing, we can't just rely on intuition to see the appearance like we did when we were freshmen. We should be able to think of something deeper." After Chang Haonan said this, he looked up. Zhang Man glanced across from him.
 "Hey, I can see something profound. It's not like you don't know. I haven't passed 80 points in any professional courses except English. For technical matters, just listen to Nanshen. Zhang Man, what are you doing? Is there any other plan?"
 Wu Yifan's words were just right to ease the situation, which not only gave Zhang Man a step down, but also prevented the relationship between her and Chang Haonan from getting too tense.
 After being beaten a little by Chang Haonan, Zhang Man quickly returned to his original bright and bright expression, as if nothing had happened, but he did not make any small moves and just pulled out the last piece of information.
 In fact, compared with the previous two real documents, what Zhang Man showed this time was just two photos.
 "There is another one here. It is a technical verification aircraft of the MiG Design Bureau. It is called Ye8. There is no detailed information. From the photo, it seems that the nose air intake has been directly changed to the belly air intake, and additional A pair of front wings..."
 Before Zhang Man finished speaking, Chang Haonan directly picked up one of the photos and looked at it.
 The Ye8 aircraft itself has more changes than the MiG-21, and it also involves the issue of three-wing surface control. It is also not a design that can be completed in a short time, but the pictures on the table helped him recall a kind of J-7 The unpopular improved model - J-7FS.
 An improved design that changes the nose air inlet of the J-7 to a mandibular air inlet, but leaves the rest of the fuselage, especially the rear fuselage, unchanged.
 Since this project was completely self-funded by the 611 Institute and had no initial users, and the research on the mandibular air inlet was not in-depth at that time, only one prototype was built for flight testing and then nothing happened.
 However, Chang Haonan knew that the potential of this improved model was actually quite large.
 More importantly, the study of the mandibular air intake itself is of great significance.
 Because future air-breathing hypersonic aircraft will also use similar but more advanced air inlets.
 Before Chang Haonan was reborn, he was preparing to test a hypersonic missile design using a mandibular three-dimensional inverted inlet at Base 29.
 According to the timeline, this modification should not have come out in 1996, or it might not even have started.
 “The air inlet design of the J-7 aircraft will be improved to enable it to adapt to larger-sized radars and ensure that the flight performance is at least not weaker than the original model.
 The specific idea is to change the nose inlet to a dual-module mandibular inlet to free up space in the nose for the radome. At the same time, the radome can be used as a conical front body and integrated with the air inlet to achieve The first-level compression of the flow is a downward-directed external compression.
 The air inlet achieves two-stage compression of the airflow, which is an internal compression method directed toward both sides and upwards, while the rest of the body remains unchanged. "
 As Chang Haonan's ideas continued to improve in his mind, the system also gave new prompts:
 [Technology points consumed to improve the project: 8 points. Points consumed to directly give the project results: 80 points. Are you sure to carry out the J-7 aircraft inlet improvement project? 】
 "confirm!"
 Almost like yesterday, the moment after Chang Haonan confirmed the project, a large amount of information appeared in his memory almost in the form of imprints. Although he had not been exposed to a lot of knowledge for many years, it seemed that he had already used it. You can become proficient after doing it a thousand times.
 In other words, the system can not only provide specific steps to complete a project, but can even improve Chang Haonan's related abilities at the same time.
 And this ability will not disappear with the completion of the project. For example, the ability he acquired yesterday to skillfully operate the fluid dynamics simulation software of this era and directly write programs in Fortran language to solve partial differential equations still exists.
 It's just that if you want to achieve inhuman operations with incredible efficiency like yesterday, you still have to rely on the buffs provided by the system for ongoing projects.
 "Haonan, are you going to choose this one?" Zhou Shuwan also took another photo and looked at it: "But isn't the design change of this three-wing surface even bigger?"
 "No, it's just that the idea is similar to this." Chang Haonan shook his head
 "The Ye8 plan's air intake is designed in the belly of the aircraft, resulting in a major change in the entire body structure. We can advance the air intake to a position almost flush with the bottom of the nose and design a mandibular air intake."
 Chang Haonan took a pen and paper and drew a simple diagram, and at the same time expressed his design ideas in as simple and popular a way as possible.
 "This can ensure that the length of the air intake is close to the original design, and the part after the 1Г cross-section of the body does not need to be modified, and we can also use the radome as a part of the air intake mechanism for the overall design, consisting of a conical radome Pre-compress the gas to improve the overall air intake performance."
 The reason why these words are wasted is naturally not due to Chang Haonan's attribute of being a teacher. Rather, according to the design method provided by the system, one first needs to manually determine the half-cone angle of a cone-shaped precursor, and then the corresponding inlet design can be calculated. Optimal solution.
 In other words, the inlet/cone front body combinations designed under different half-cone angles are quite different.
 However, Chang Haonan does not know how many half-cone angle corresponding design solutions will have the best effect after being installed on the J-7.
 In the field of design, choosing initial values ​​depends largely on experience, but Chang Haonan, as a military screwdriver before his rebirth, had no experience in mastering the overall design of a model...
 So he next needs to make several different plans, simulate their performance when combined with the J-7 body, and then explore the rules from them, and finally find the best performance option.
 The workload of this process is very large, but a lot of the content is actually repetitive work with little innovation, so it can be completed by three other people, while Chang Haonan himself concentrates on the most critical part.
 Firstly, this can improve efficiency, and secondly, it is in line with his vision of the future use of the system, so it can be regarded as a preview.
 "This way the workload is indeed much smaller, and many parts can even be used in common with the original model."
 Zhou Shuwan hammered his fist on the palm of his other hand, making a crisp sound: "Haonan, please tell me what to do next. We will all obey your command!"
