Chapter 829: This design is interesting
First of all, as the positioning of a light fourth-generation aircraft, the designer was able to design two large bomb bays that were already very good, and they were forced into the F-35 fat electric bomb bay design scheme, not only after giving up many aspects did they get two large bomb bays plus side bomb bays!
Even the Russian-designed T-50 does not have a side bomb bay design at all, and the fourth-generation aircraft plan that the Republic of China came up with on the northeast side of the country did not have a side bomb bay design in the end. Pen "Fun" Pavilion www.biquge.info
And now the most important point, Yang Hui is clear at a glance that the bomb bay design scheme in the light four plan obviously has some room for further excavation, if the design can be reasonable enough, it is still very possible to take out another bomb bay from the central axis of the belly, and the design scheme of three large bomb bays will be enough to use at that time.
Thinking that the bomb bay design scheme could be optimized in the future, he took advantage of the stall where the chief landing engineer took a breath and interjected: "The design brought by the chief engineer Lu is indeed very good, as for the problem of the bomb bay, we can optimize it in the future, this aspect can not be too much attention for the time being, I think it is better to continue to talk about the aerodynamic design of this aircraft!" ”
Obviously, the aerodynamic design of the light four has not been fully said this time, and the highlight of the aerodynamic design of the light four is definitely not only the clever cooperation between the air intake and the wing, at least Yang Hui saw another ingenious design at the air intake at this time.
As soon as Chief Lu heard Yang Hui say that there was still room for optimization in the design of the bomb bay, he understood the situation at this time, and it must be that Yang Hui had some new ideas, and it was not good to say it directly at this time due to some special circumstances, so he only proposed to skip the bomb bay design for the time being, so that Mr. Lu was happy to continue the topic on aerodynamic design.
"Regarding the aerodynamic design scheme, there are indeed some new designs that have been applied to the design of the air intake, and this is mainly inspired by the design of the American F-22 fighter, now you can take a closer look at the outside of the air intake, here I designed a folded line, but you guessed its function?"
The folded line design on the outside of the air intake, which is an indispensable design for stealth fighters, has been used for the F-22's Garette air intake since the beginning of the folded line is only based on stealth considerations, and plays the same role as the folded line in the nose design of stealth fighters.
And this has long been the consensus of all stealth fighter designers, especially the two chief designers Yu and Song, who have had a lot of research on stealth design before, they are very clear about this design, especially Chief Engineer Yu, who also has the same design in his heavy four plan, but due to various reasons, it is not as exquisite as Chief Lu's plan.
Therefore, when Chief Engineer Yu saw the folded line of the outer inlet of Chief Lu's plan, he couldn't help but sigh: "Chief Lu's design plan is indeed exquisite, especially in the aerodynamic design, which is definitely a classic in the light fourth-generation aircraft, and the status is probably comparable to the F-16 in the third-generation aircraft!" ”
It seems to be a bit arbitrary to be able to use the F-16 in the third-generation aircraft to describe the status of the light four in the fourth-generation aircraft, but it sounds very reasonable to Yang Hui, and it is difficult to have the kind of multi-party tearing war in the future fourth-generation aircraft design, and the fourth-generation aircraft era is mainly China and the United States to provoke the girder, and the king of the light fourth-generation aircraft is nothing more than the competition between the light four and the F-35.
And to talk about the F-35 project, of course Yang Hui knows what kind of pit ratio project this is, to use the F-35 and the light four to compare, Yang Hui first in the aerodynamic design to give the light four a complete victory, if the two meet in the air battle in the future, the same situation is definitely the light four better than the F-35.
At least no matter what, the F-35 project is a joint strike fighter, why the "attack" will be in front of the "battle", which obviously shows that in the early design requirements, the F-35 is more focused on attack, regardless of the various requirements of the American allies in the later period, the F-35 strengthens air superiority, but the body design of the aircraft is there, and the aerodynamics of the F-35 are not the material for the air superiority aircraft at all.
But at this time, the people attending the meeting were naturally not clear about the F-35 project, at least at this time, the JSF joint strike fighter project had not yet begun, and it seems that the previous project was not launched until 96, and it was not even until 2001 that the final choice was decided.
Although the development of military equipment in the United States is relatively open in many cases, there are no shadow projects at all, how can you make it public?
But when the words just fell, Mr. Lu also continued to uncover the mystery: "The polygonal design on the outside of the DSI inlet duct is not only for the needs of stealth design, at that time, when we conducted wind tunnel research on the aerodynamics of the F-22, we have found that the folded line of the F-22 inlet is not only able to play a stealth role, but even we have found that it can play a role similar to the side strip wing, and the aircraft can also pull out a beneficial detachment vortex in the flight state of high angle of attack." ”
When it comes to the edge wing, Sun and Wu of course the two new generation of chief designers can be more clear, after careful study of the fold line, it is also found that the fold line can indeed achieve some of the role of the edge strip wing, the fold line can pull out a beneficial detachment vortex, the vortex can achieve a great aerodynamic gain when flowing through the upper surface of the main wing.
After Mr. Sun figured out the function of this broken line before and after, he was also admired: "This design is so exquisite, it can really be said to simplify the complex!" The design of the edge strip wing started from the small side strip of the early F-5, then the S-shaped edge strip of the F-18, and then the large side strip on our YZ-1 verification aircraft. Previously, the 0111 Institute's research on the edge strip wing could claim to be the most cutting-edge in China, and now the light four plan has come out, which really makes the younger generations admire. ”
Seeing Chief Master Sun's performance, Yang Hui smiled and didn't say much, to say that the side fold line design outside the DSI air inlet duct actually looks almost 80% similar to the F-35's side fold line design outside the air intake.
But considering that the F-35 fighter at this time is still in the protein stage, Loma has not even gotten the design tender for the JSF project, so there is absolutely no plagiarism in the light four, which can only be said to be the same way, as long as everyone designs in the direction of the fourth-generation aircraft, then it is not surprising that there are some coincidences in the design.
Just when everyone sighed at the wonder of the design of the outer fold line of the air inlet of Master Lu, only Yang Hui and Chief Master Song did not move, especially the Chief Master Song's side frowned, because he had already seen the strangeness of this folded line in the design, although this folded line played the same role as the side strip wing, but it was definitely not the same thing.
The more I thought about it, the more I felt that something was wrong, but Mr. Song was interested, and now this design is quite interesting..........
