"The entire laser targeting and infrared navigation system will be the key to our ground attack. The system is divided into two parts, and the role of laser aiming is needless to say, it is the existence of providing guidance information for laser-guided bombs. ”

Of course, the whole system is not only laser aiming, but also an infrared navigation system, which is also a must.

"The infrared navigation system can provide infrared information about the target at night, or provide infrared navigation information near the flight path in ultra-low-altitude flight, so that the fighter can also achieve accurate ground attack operations at night."

As Chief Engineer Li continued to speak, he finally made the southwest science and industry plan roughly clear, and the technical indicators of the entire new annihilation were constantly raised, and the army's side also seemed to have a higher vision.

"We also have a general understanding of the southwest science and industry plan, very unique ideas, and the general technical data have also been seen, although there is still a gap between the distance and the requirements of the 4000 kilometers without conformal fuel tanks, but it can also be put later."

……

It took two days before and after the Southwest Science and Industry Program Show, and the entire new J-1 bidding also entered the final stage of the Xifei Program Speech, but the chief engineer of the Xifei looked a little listless.

Chief Chen originally came on the spot, preparing to win the new annihilation project, and the ambition to resurrect the flying leopard has long been gone.

"Our plan adopts some aspects of the technology that has been verified by the old Flying Leopard, and continues to use the fuselage design of the Flying Leopard, the air intake is moved downward, and the wing is changed to a medium single wing design, so that the new J is far stronger than the old Flying Leopard in maneuvering......"

Sure enough, it was as I had guessed at the beginning. The Westward Flying Program is still a major change to the Old Flying Leopard Program, mainly to improve mobility.

For this kind of move in the West. Yang Hui didn't think there was anything wrong, this time the new J-1 indicator was changed from the flying leopard indicator.

And that's just the range requirement. Except for the existence of the perverted design of the old flying leopard, no fighter can achieve such an internal fuel range, and besides, ......

"Although our plan this time cannot be compared with other solutions in terms of maneuverability, the plan we brought to the west is the only one that achieves the 4,200-kilometer range target under normal loading."

Speaking of which, several other units are also interested, for the 4200-meter transfer range given by the army, each unit is scratching its ears and cheeks, and in the end, it is all through other wonderful solutions to meet the technical requirements, and now Xifei said that it can be done through conventional technology mounting. That's right......

Hearing Xifei's words, even the military side that was originally a little skeptical about whether the range index was set too high this time also became interested, it seems that there is nothing difficult in the world, but I am afraid that there are people who have a heart!

"Oh, then let's talk about it, I want to see what kind of technology your plan uses this time, and you can actually use the old flying leopard's body to achieve such a range index."

Perhaps also sensing the curiosity and surprise of the army, the Science and Technology Commission and other bidding units, Chief Chen also smiled bitterly, in the eyes of others. What kind of high-tech is used to achieve such a big leap forward in the old flying leopard fuselage this time, but in fact, it is ......

Smiling, Chief Chen is not mysterious: "This is actually a very simple thing, the old Spey 202 engine is more than 1 meter longer than the size of the turbofan 12 this time." The space freed up by a new turbofan 12 engine. All the fuel we used to load was naturally able to meet the requirements of the transfer range required by the army. ”

After listening to Chief Chen's answer here, this can be regarded as the reason why the voyage of the Westward Flight Plan can be so perverted.

"We were negligent, but the replacement of the turbofan 12 engine can achieve such an effect. However, it is also a loss to redesign on the basis of the old flying leopard, otherwise it would not have achieved such an effect. ”

The navy listened to the reason for the increase in internal oil in the westward flight plan. I think of the same model that replaced the old engine, when the US Navy replaced the old TF30 engine of the F14. It was quite a struggle.

The size data of the old TF30 engine is also not small, this engine is actually the same level as the Spey 202 engine, and it also bid for the early power of the F14 together that year.

The TF30 engine has a longer length than the 202 engine, with an unprecedented length of 6 meters. But in the end, the United States still used the TF30 engine as the power system of the F14A, and the reasons are naturally diverse.

What I want to say here is that when the United States imperialism replaced the engine for the F14, the new F401 engine was derived from the improvement of the F100 engine, and the length of the F100 engine was only 4.8 meters, and the gap with the TF30 was not a star and a half.

In order to balance the difference in the length of the engines and ensure that the original design of the aircraft would not change much, the US Navy had to extend the original 4.8-meter-long F100 engine.

That's right, you heard it right, it's just that the engine size is artificially extended, although it is claimed that the engine length is extended because of the engine push, but such nonsense......

In many cases, changing the original engine of an aircraft is an absolute major operation, especially when there is a huge difference in performance and size between the two engines.

In order to meet the use of old aircraft, the new engine is either changed to the aircraft structure or the new engine.

This kind of thing is sad, but fortunately, this time the Xifei plan has taken the previous path, and it seems to be working well.

"The effect after replacing the engine is not bad, but what is the plan you brought this time, you must have a good idea, we won't say more, this plan report is here!"

With Director Ding announcing the completion of the plan report of the five units, the Xifei plan has also become an irrelevant role for the prince to study.

At this time, although Chief Chen was a little disappointed in his heart, it was not a real relief. He has been circling around the Flying Leopard Project for nearly 20 years, and it seems a pity that he finally got such a result......

Stepping off the podium, several bidders returned to their ranks, until the army stood up and announced.

"At the end of the program report, we will soon select the two programs with the most development potential according to the plans given by each unit, and the results will be announced within a week.

With the departure of the army, the Science and Technology Commission, and the Ministry of Aviation Industry, the five units also walked out of the auditorium, and they also walked out of the auditorium, but this time their hearts seemed a little different.

From this moment on, it has entered the "waiting period for marking after the college entrance examination", such days are absolutely difficult, although the project plan is very good, and it seems that there is a good chance to enter the final finals, but no one can say this thing......

"It can't be said that the two technical indicators proposed by our Southwest Science and Industry this time are actually not only what we can do in Southwest Science and Industry."

In the face of Chief Master Chen, who came to take the initiative to talk this time, Yang Hui did not have any need to hide privately, on the one hand, Chief Master Chen said very clearly. He knew that there was no hope for the Xifei plan, and he just wanted to chat with Yang Hui this time.

At the same time, there is also a taste of discussing with Yang Hui to figure out where the gap between his plan and the Southwest Science and Industry plan is, and he wants to lose.

Yang Hui's answer is not optimistic: "To say that the aerodynamic layout of high maneuverability is better than ours, the digital avionics system is not the operating system of the aircraft, it can also be designed as a subsystem, the same is true for laser targeting and infrared navigation systems, if we want to work in the southwest section as a subsystem supplier, we also have to do the same." ”

After listening to these, Chief Engineer Chen understood Yang Hui's words, and also had a deeper understanding of the strength of Southwest Science and Industry, and was able to integrate the components in order to achieve the same goal into a strict subsystem, which is enough to reflect the advanced design concept of Southwest Science and Industry.

"In other words, the two systems you proposed this time that are related to the key combat capability of the Southwest Science and Industry Program can be extracted separately to become a system, just like airborne radar, and can also be used in several other programs?"

Sure enough, they are all smart people who do this business, and they are still very sensitive in technical issues, and they understand what Yang Hui means as soon as they say it.

"Yes, in terms of conventional aerodynamic layout, our Southwest Science and Industry Program should be the best, but compared with the canard aerodynamic layout of the 611 Institute and the variable swept wing layout of Hongdu, we are only half a catty or eight taels in aerodynamics. And our two killer features of Southwest Science and Industry are not only unique, if the other two solutions are installed with the avionics and laser targeting systems developed by our Southwest Science and Industry. I really don't see who will die in the end! (To be continued.) )
