Chapter 1452: New plan (5)

The sketch spread out on the table drew a strange-looking aircraft. The nose and fuselage of this aircraft are similar to the "Yun 7", but the tail is completely different. The "Yun 7" is a typical single hanging The tail, low-level tail, but the plane on the sketch has 4 vertical tails!
Moreover, there is a huge disc on the back of this plane!
To the few people sitting in this room now, they are very familiar with the appearance of this aircraft, because this is the sketch of the famous metric E2 "Eagle Eye" early warning aircraft!
Of course, the person who is most familiar with this aircraft is Lu Hesheng, you know, E2 is also one of his masterpieces when he was the host designer at Grumman!
The E2 early warning aircraft, the only active early warning aircraft of the U.S. Navy, began its development in 1957, and made its first test flight in 1960. In 1964, the first model E2A was delivered to the U.S. Navy, nicknamed "Eagle Eye". It has ship-borne early airborne early warning and air control capabilities. It has also been purchased and equipped by Gaul, Singapore, Japan, Isaac and other countries. Among these countries without aircraft carriers, E2 assumes the function of homeland air defense early warning aircraft. It is the world’s largest production and widest range of early warning aircraft.
Since its installation in the 1960s, the E2 early warning aircraft has undergone many upgrades and modifications. The latest model is E2C. The radar equipped on it has been upgraded from AN/APS-96, which can only detect 200 kilometers, to AN, which can detect 480 kilometers. /APS-138 radar. In addition, a set of AN/ALR-59 passive electromagnetic signal reception and detection system with a range of more than 600 kilometers has been added. The engine is also from a single T-56-A-8 turboprop engine with 4050 shaft horsepower. Upgraded to a single T56-A-427A with 5100 shaft horsepower.
Now that Tan Zhenhua has picked out his aircraft carrier plan, although the people sitting in the room want to break their heads and cannot guess how he will solve the most important problem of the big ship, he must insist on advancing from his own pocket. "JH- It can be seen from the development plan of the "7BH" model that the rich man is serious, so he wants to build a ship-borne early warning aircraft. In fact, it is logical to think carefully.
But this is an early warning aircraft. It is a model that China has been searching for for many years and cannot find it. Even if Tan Zhenhua has money and does not have enough technology accumulation, can he get it?
Regardless of how to solve the problem of the radar that is very different from the requirements of the land-based radar, this carrier aircraft is a big trouble.
Basically, the most advanced and most successful early warning aircraft in the world is the Americans. The first real AWACS in the world was modified and applied by the Americans on the TBM-3 fish bomber in World War II. Okay, students. You already know that the TBM-3 torpedo bomber used to be the car of the current president of the United States, Bush, and the chief designer who developed this fighter was sitting in the house at this time...
After World War II, the Americans took the lead in creating the E2 series of early warning aircraft, and the chief designer of this aircraft was the same one.
Lu Hesheng felt that his mind was a little messy-did you say that Tan Zhenhua got him because he really liked Vivienne, or did he deliberately approach Vivienne because of these carrier-based aircraft?
Also, when is this kid planning to marry Vivian?
He shook his head, threw these messy thoughts out of his mind, and said in a deep voice: "Zhenhua, let's first assume that you can indeed get an aircraft carrier, but I have to remind you that, based on my understanding, "Yun 7" The
WJ5AI
currently in use on the board has a take-off power of only 2133 kilowatts and 2900 horsepower, which is absolutely not enough for an early warning aircraft with a take-off weight of more than 25 tons. Even the most primitive E2A has a single engine power. It has also reached 4050 horsepower, and the current E2C has been upgraded to a single 5100 horsepower. Does China have an engine of this power? I have to remind you that this is purely military equipment, and no one else can sell it to you."
"In fact, we have a more powerful turboprop engine." Tan Zhenhua replied: "The "WJ6", which is the same as the "WJ5" series engine, can achieve 3124 kilowatts and 4250 horsepower with the current state of the art. This engine It has also undergone long-term flight verification on the "Yun-8" transport aircraft, and its performance and reliability still meet the requirements, but this engine is after all an imitation of the Soviet Russian AH-20M without any original data. In the future, compared to the prototype, it is still slightly inferior in terms of power, power-to-weight ratio, refurbished life, etc., and there is a big gap with similar Western products, but under the current situation, it can still be used, and I intend to use it here. I will make an investment in the type of engine. I will go back and talk to Mr. Wu. What I want to know now is, with this "WJ6" as the power core, is it possible for us to build a Chinese version of the E2? ?"
"Wait a minute, Mr. Tan, I have to ask you a key question." This time the answer was Gong Guozheng, the host designer of "Yun 7". He asked: "Looking at what you mean by this picture, it should be in " A major change on the basis of Yun 7"? But first we have to figure out whether the take-off method of this aircraft is the catapult method used by the Americans or the ski-jump method like the aircraft carrier being built by the Soviets. Without knowing this, many basic parameters of this aircraft cannot be determined."
"My opinion is that the aircraft is still designed according to the catapult takeoff method, but it needs to be considered to take off on the ski jump deck." Tan Zhenhua replied: "I think so. Catapult takeoff is a general trend in the development of aircraft carrier loading aircraft, and it is The aircraft developed for catapult take-off is actually compatible with the ski jump takeoff method, provided that the lift conditions are met, Grandpa Lu, am I right?"
Lu Hesheng shook his head and said: "In the early days of World War II, carrier-based aircraft did not have a catapult takeoff method, but at that time the aircraft were powered by piston propellers. The weight of the aircraft itself was low and the low-speed performance was better, so this type of takeoff was not needed. Auxiliary equipment, catapult is actually developed after carrier-based aircraft entered the jet era, because the aircraft’s take-off weight is getting heavier, but I can’t answer your question, Zhenhua, because I personally haven’t done it on the ski jump deck. For jet aircraft taking off on board, only the British "Invincible" class light aircraft carrier in the entire Western world has adopted this design, but this is based on the fact that the carrier-based aircraft on it is the "Sea Harrier" that can take off and land vertically or short distances. As far as I know, the British were not equipped with fixed-wing carrier-based early warning aircraft on this type of aircraft carrier. They used a modified "Neptune" class helicopter to perform similar tasks."
Tan Zhenhua, of course, cannot explain to you at this time. In fact, the Americans have calculated the specific data of E2 taking off and landing on the ski-jump aircraft carrier deck and conducted special tests. The test data has long been used by China's military forums. It was clean, because for a while, equipping China's "seesaw" with fixed-wing early warning aircraft was a major concern for all military fans in the country!
However, since it has been proved in American tests that under 25 deck winds, the E2 with a take-off weight of 25 tons can take off normally on the 12-degree upturned runway at the end of 165 meters, even because the E2 has a propeller. The reverse distance, it can stop at a distance of 100 meters without the help of a blocking cable, then his idea is feasible, and what he has to do now is to organize a group of people to gradually realize his idea!
