Chapter 2182: Modification

Hearing what Lu Lao said, Qin Guan was also very happy, and immediately nodded: "Of course. In this case, we can also have a batch of more technologically advanced aircraft that can continue to have an advantage in the sky before our new fighters are put into service. ."
Thinking about future generations, many fighters are not up to the level of fourth-generation fighters, but they feel that they are higher than third-generation fighters. Therefore, there is a 3.5-generation fighter. What's more, there are three points. The argument of the fifth-generation fighter is not enough, so I made a three-point and five-generation argument. In short, I put gold on my face. Our aircraft is not enough for the fourth-generation aircraft. It’s not much worse than the fourth-generation aircraft. Although these statements have some problems, the development of the fourth-generation aircraft is very difficult. Therefore, many aircraft in flight are not up to the standard, but have better performance than the original third-generation aircraft. High is an indisputable fact.
Now that Mr. Lu has mentioned it, of course he can support it. However, this is also a prerequisite. There can be no major changes. Otherwise, the price will rise. After all, the vast land of Han must be maintained first. Only an aviation unit of sufficient scale will work. If the price goes up, the quantity of equipment will not be too much.
"Great, President Qin, you also support us, so we can make changes according to our own ideas." Lu Lao said: "This modification is mainly in terms of appearance. We only need to change the mold and production process. Yes, let’s start from the nose."
In the era of the third-generation aircraft, most of the nose is round, so it is considered to have the least resistance. In the fourth-generation aircraft, the nose is mainly diamond-shaped, which can reduce the radar reflection area.
We have already tested the fourth-generation aircraft plan. The main one is the modification of the shape, which is naturally the same now. The nose is changed to a special shape with a tilt angle to reduce the radar reflection area of ​​the nose. The inlet is blocked, so that the blades of the turbofan inside are not exposed directly, reducing radar reflections. In the back, the tall double vertical tails should be inclined outwards, which can also reduce the height at the same time.
Of course, these changes will increase the air resistance of the aircraft, and the maximum speed will drop slightly if the engine does not change, but it should be worth it compared to what we got.
At the same time, these changes will not have much impact. The original pilot can complete the modification of the new aircraft after simply flying over the simulator. It is very simple.
Since it is a fly-by-wire flight control with more than four degrees, so as long as the flight control system is optimized, there is no big problem in flight. In short, this is the lowest cost improvement method.
"Are you not going to change its missile mount?" Qin Guan asked.
In these changes, Mr. Lu did not include the design of the built-in bomb bay. Now, after hearing Qin Guan’s question, Mr. Lu shook his head: "This is not going to be changed. Now, we are still optimizing the ejection mechanism of the missile. The built-in weapon bay can greatly reduce the radar reflection area. However, for our current aircraft, the price paid is too high. Similarly, there is also the phased array radar."
The built-in weapon bomb bay is quite complicated. The missile can be launched by directly igniting the missile on the pylon. After entering the bomb bay, you must open the door and throw the missile out before firing. In the distance fighting, you may not be able to grasp the first opportunity, which is also a disadvantage of the fourth-generation aircraft.
Therefore, although many 3.5-generation fighters have undergone detailed changes in all aspects, they rarely choose built-in bomb bays in terms of mounting missiles. Anyway, they are not completely pursuing perfect stealth. There are technologies to reduce the radar reflection area. This improvement is not worth the loss, so it is not carried out.
You know, the volume of the built-in bomb bay is limited after all, and the main Phoenix missile of the J-11 fighter cannot be inserted.
Now, Qin Guan got the answer from the other party, and was still very satisfied. They did not blindly pursue advancedness, but made a reasonable compromise. This is a very reasonable choice.
Similarly, there are phased array radars. For the fourth-generation aircraft, going out with a phased-array radar is the only way to show off. If there is no phased array, it is definitely not enough for the fourth-generation aircraft. The research and development of the phased array radar system has been completed, and it is used on early warning aircraft and warships. However, these are equipped with a small amount after all, and fighters are a large number of equipment. The current flat-panel slot radar has a very low cost. , The performance is also good, if you install a phased array radar, yes, the performance is improved, but at the same time it will also bring a soaring cost.
Therefore, Mr. Lu did not make this improvement. Such an upgrade is the most economical. In the future, with the continuous advancement of electronic technology, the cost of phased array radar will come down, or the country will become more affluent. With its economic strength, it’s not too late to install this radar.
Qin Guan made the final decision: "Yes, we will carry out trial production in accordance with this plan. After success, we can mass-produce new F-11 fighters with improved appearance. I personally firmly support this improvement."
There are still many difficulties in the fourth-generation aircraft, ranging from the ejection of missiles to the engine with a thrust-to-weight ratio of 10, all of which need time. The technology that has now been verified is used to improve the existing fighters to reach 3.5-generation. The standard is definitely a good plan.
Of course Qin Guan supported it.
Time passed quickly. The missile experts studied for a long time. Finally, when it was time for dinner, most of the people went back to rest after having dinner in the factory.
As before, Qin Guan strolled around and walked to the staging area of ​​the J-11 fighter. The fighters here were the ones waiting to be refurbished.
Xiucai and Xiao Lu walked behind Qin Guan, knowing that Qin Guan was about to use his superpowers, so they had cleared the field in advance to ensure that there were no people around here and no one would see them. After all, these fighters were too Too much, it is impossible to find a closed place to use super powers for Qin Guan.
"These are all our meritorious aircraft." Qin Guan sighed himself: "It is this batch of fighters that made our air force's equipment finally enter the modern sequence."
The J-11 and J-10 have already supported the sky of the motherland, and these fighters have reached the end of their lifespan. Now, let yourself refurbish them!
Qin Guan entered the system, and skillfully clicked on the various interfaces, and then entered the aircraft cemetery of Eagle Country. Here, the scene was exactly the same as before.
