Chapter 747: The Shield

"Mr. Serge gave a wonderful introduction, highlighting the advantages of the Mirage 2000 fighter jet."
Without waiting for Song and Chen to speak, Tan Zhenhua spoke first: "But I heard that the "Phantom 2000" fighter was dragged down by the performance of the M53 engine selected, and its climb performance was not very good. This is a volley that we pay special attention to. The combat situation is very unfavorable. How about Mr. Serge telling us about the performance parameters in this respect?"
"Uh, this..."
Serge was suddenly enlisted in the army, and he was a little speechless. Fortunately, Charles, who was sitting next to him, saw that the situation was wrong and immediately took the conversation: "In fact, the M53-P2 engine currently installed can provide afterburner thrust. With a power of 95 kilonewtons, it takes about 50 seconds for the "Phantom 2000" fighter to accelerate from Mach 0.7 to Mach 1.3 at an altitude of 5000 meters; and at an altitude of 10,000 meters, it takes 184 seconds to accelerate from Mach 1.0 to Mach 2.0; its sea level The maximum climb rate is 255 meters per second, and the climb rate at high altitudes and supersonic speeds can reach about 150 meters per second. These data cannot be said to be bad, but they are not particularly prominent among the fighters of the same generation, and we The M53 engine is being improved. The next production batch is expected to increase the maximum thrust to 98.1 kN. By then, the climb performance of the "Phantom 2000" fighter will be further improved. Mr. Eric, I personally think that these should not It became an obstacle for China to purchase this fighter."
Tan Zhenhua nodded slightly, but didn't mean to let it go: "Then Mr. Charles, can you tell me, when will the next mass production batch of engines be put into mass production?"
"...I'm sorry, Mr. Eric, the improvement of aero engines is not a simple matter. I am afraid that I cannot promise you the most accurate time. Therefore, I actually want to suggest that you consider a compromise solution, first based on the current state of the art. I personally think that this plan is relatively safe to deliver the aircraft and then replace it with a new model of engine during mid-term maintenance."
"That is to say, before replacing the engine, the fighter will face insufficient thrust, and if the thrust is insufficient, the thrust-to-weight ratio will naturally be low, and the stability of the plate is definitely not ideal, right?" Tan Zhenhua continued to pursue it.
Stable disk, often associated with instant disk, is another description of the agile performance of a fighter.
As the name implies, the steady plate means that the thrust of the engine can offset the drag when the aircraft is in a circling motion.
In other words, the aircraft can maintain this hovering for a long time without losing altitude or speed, maintaining its own kinetic energy and potential energy.
In the mid-air combat where the bayonet is popular, maintaining the energy of your fighter is often the key to victory.
Tan Zhenhua lightly hit the table top with his knuckles and said: "The reason why I value the ability of the aircraft to stabilize the disk more than the instant disk is because, according to the latest popular, the US Air Force Major John Boyd put forward the "energy maneuver Theory "In air combat, although there are many factors that determine the outcome of the two sides, the most important one is energy, the available energy! And the ability to stabilize the plate." He paused and looked up at the opposite side. Serge and Charles said:
The ability to stabilize the disk is one of the key performance indicators for aircraft to maintain energy.

His words made the faces of Serge and Charles a little ugly, but Song Wenhua looked at his famous student with a surprised look as if he had discovered a new world. As for Chen Yijian? He smiled and stared at Tan Zhenhua, but there seemed to be something extra in his eyes.
After a moment of silence, Serge finally spoke again, but his tone contained a hint of helplessness: "Although I don't want to admit it, but based on the rigor of an engineering researcher, I have to admit, Eric, you say Perhaps it is correct. In its current state, the "Phantom 2000" fighter is slightly insufficient in stability. However, Charles just said just now that this problem is expected to be alleviated after the new engine is put into use."
Tan Zhenhua nodded and said: "Mr. Serge, Mr. Charles, I accept your explanations and suggestions, and by the way I am sorry, kid, I'm just a layman in the aviation industry, and you two shouldn't take it to heart. It does not deny that the "Phantom 2000" is an excellent fighter. I also know that designing a fighter is an extremely challenging task. Engineers must make choices about the final result under limited conditions. What I said just now is just to put forward some of my suggestions. I hope that "Phantom 2000" can do better in the future improvement work."
When he said this, he finally relieved the slightly embarrassing atmosphere in the house a bit, and Charles took over Serge's words and continued on.
"On the "Phantom 2000" aircraft, we have adopted a lot of the latest research results," he said. "The most commendable is that we have adopted the mature 4 degree fly-by-wire control system, which relaxes the static stability. This move not only greatly improves the aircraft’s landing performance, but also improves the aircraft’s maneuverability."
This is the general trend of the world's new generation of fighters. Song Wenhua and Chen Yijian nodded slightly to express their approval.
Charles went on to introduce: "We have also applied the latest display technology. The advanced cockpit is equipped with a head-up display and a down-view display, which greatly improves the ability of pilots to obtain information. The latest CSFRDY pulse Doppler radar developed by Thomson has Complete air and ground functions, multi-target capabilities and good anti-electronic interference capabilities. In the air-to-air state, it has speed search, scanning and ranging, multi-target searching and tracking, air combat evaluation, Air combat, single target tracking and other working methods, its maximum detection range is 130 kilometers, it can track up to 8 targets at the same time and lock 4 of them, if it matches our radar-guided medium-range air-to-air missile "Mika" , It can perform fire control calculations for 4 missiles at the same time; this radar also has a strong air-to-ground capability, so that the "Phantom 2000" fighter can fully perform deep attack and close support missions."
Tan Zhenhua interrupted Charles' narration and asked: "What is the data cross-linking between the radar and the fire control system?"
"We adopted a digital multi-channel data bus cross-linking, the bus is controlled by a 16-bit, 64K reserve computer, and the communication equipment, inertial navigation equipment and radio navigation equipment equipped on the plane are also cross-linked on this bus. This allows the pilot to better manage the flight status of the aircraft." Charles replied.
Tan Zhenhua nodded in satisfaction, and then said: "Thank you very much, Mr. Serge and Mr. Charles, for explaining this "Phantom 2000" fighter for laymen. Although it has some points worthy of improvement, I have to admit that it is indeed a An excellent fighter, Mr. Serge, you may have heard from Mr. Jacob, I am a very direct person, so I have one more question next."
"Eric, you are welcome, please." Serge said casually
"Well, the question is, if I ask that in addition to purchasing the "Phantom 2000" fighter, I also need to purchase the full set of technologies, drawings, patents and production licenses for this fighter. How will Dassault consider it?"
"What? Oh? No, Eric, we only sell fighters at Dassault, and the rest are not for sale... And, why do you buy those things? Do you plan to lay the hens in order to eat eggs? Buy it back?"
"Because" Tan Zhenhua replied with a smile: "Just now at lunch, Mr. Serge reminded me of one thing, and I happened to think of some unpleasant encounters between Isaac and Argentina."
