Chapter 655: Has the technology of early warning aircraft regressed?(1/2)
Mr. Lin immediately guessed the meaning of these numbers at first. They were just to compare with X-32 and X-35. They were disgusting to Americans. However, Wu Shengli obviously didn't think about it so much. He just thought about it briefly.
He nodded: "Then let's kill the Thirty-Two, we have to follow the order."
Therefore, this carrier-based aircraft was officially designated as the J-32. From now on, it will be all-powerful and give headaches to those with ill intentions.
The production of the J-32 was officially started after Qin Tao left. Zhao Dangsheng continued to be in charge here. The research and development and continued improvement and upgrading of several other models were still in charge of Pleshakov, with Wu Shengli taking the lead.
Qin Tao went to No. 603 Institute and No. 172 Factory without stopping.
These are of course preparations for the next aircraft carrier. Next, the Navy will officially start construction of the second aircraft carrier. Mingzhou Group must be prepared for various preparations related to the aircraft carrier.
As for the bidding of Bincheng Shipyard, everyone just needs to see through it without saying anything. Qin Tao is clearly here to accompany him. If only one factory of Mingzhou Group bids, it will not be justified.
Bincheng Shipyard was once the largest warship manufacturer in the country. It produced many warships and also bid for destroyers. Now it continues to bid for aircraft carriers. This can be seen as fair and reasonable. The navy chooses the best.
On the warship, other projects are almost done, but now we just need an early warning aircraft.
The project of carrier-based early warning aircraft has been arranged for a long time, and the 603 Research Institute is also working tirelessly, and the progress is very good. This time, Wu Shengli just wants to take Qin Tao to take a look.
Qin Tao has been running around here and there, and has not paid much attention to the early warning aircraft project in the past year.
When everyone arrived at House 603, Mr. Chen, who had received the news, was already waiting at the door.
"Mr. Chen, you are moving very fast." After seeing Mr. Chen, Qin Tao said with a smile: "I heard that the prototype has been built?"
"That's right, the airframe has been built, and the early warning radar equipment is now being installed in the workshop." Mr. Chen said, "Now, the R&D team of the early warning aircraft is also there to help. Leader Wu, Mr. Qin, you are here to listen first.
Do you want to listen to our report or go directly to the workshop?"
"Of course it's the workshop, what's the use of listening to the report?" Qin Tao said immediately.
So, a group of people went to the specialized early warning aircraft assembly workshop.
Zhao Ling looked through the window and looked outside. Since becoming Qin Tao's assistant, her life has been completely different from before. She traveled around, met all kinds of people, and came into contact with all kinds of R&D secrets.
A new life filled her with freshness and a new kind of happiness.
Brother Tao is so awesome, he can do anything! No matter who he is, he seems to be familiar with him, and the eyes he casts are full of respect and even admiration.
She felt proud of Qin Tao.
In the workshop, a group of people were busy. After Mr. Chen entered, he shouted: "Xiao Duan, Xiao Duan, stop working, Leader Wu and Mr. Qin are here."
Duan Yi climbed down from the scaffolding, walked over quickly, and looked at the people who came.
"Leader Wu, Mr. Qin, hello, our early warning aircraft is under construction schedule, so don't be surprised if I didn't go to greet you. Welcome to come and inspect the site." Duan Yi said, stretched out his hand, intending to shake hands with the leader, but
, his hands were full of dirt, and he planned to retract them and wipe them on his clothes.
Wu Shengli had already held his hand: "Mr. Duan, thank you for your hard work. Our navy's fixed-wing early warning aircraft depends on you!"
Qin Tao had a smile on his face. The person in front of him looked like he was only thirty or forty years old. He had already become the chief designer of this early warning aircraft. The research team is getting younger! Only in this way can the development team be full of vitality.
and vitality.liquid
"Mr. Duan, have you been responsible for this project?" Qin Tao asked.
"Yes, Mr. Qin, you left everything to us at the 603 Institute. Mr. Chen couldn't get away from studying the J-H-7, so I volunteered and stumbled up to now. I hope the test flight will go smoothly. Don't let you down.
expectations."
"Well, first
Tell me about the aircraft." Qin Tao looked at the early warning aircraft in front of him and felt very satisfied.
If you look at the shape, it is very similar to the E-2. There is nothing to say about it. After all, the Yak-44 early warning aircraft is called the Hawkeye Sky, and our own carrier-based early warning aircraft is based on the Yak-44 and Yun-12.
Improved on the basis.
The straight wings, four vertical tails, and a large plate on the back are all similar, but there are also different details.
For example, the propeller is coaxially counter-rotating, and the propeller blades look like a machete, which looks very powerful and domineering. The nose is also slightly shorter.
"Mr. Qin, let me first introduce to you the overall parameters of the aircraft. The length of this aircraft is 18 meters and the wingspan is 25 meters. Of course, the wings can be folded for easy access to the hangar. After the radar and electronic equipment are installed,
The weight can be kept at about twenty-five tons." Liquid
The empty weight is equivalent to the total weight of the E-2. There is nothing we can do about it. After all, there is still a gap between our own technology and the United States. However, compared to the weight of the Yak-44, it is much lighter.
"After being filled with fuel and personnel, its total weight can be kept at about 30 tons. This can be regarded as a satisfactory completion of the design indicators without any overweight."
When we first planned it, we aimed at a total weight of thirty tons, and now it has been successfully completed.
"At the same time, we use the D227 engine you provided for its engine. Under normal circumstances, we only need to use about 8,000 horsepower. If an engine suddenly stalls unexpectedly during takeoff, then
, the other engine will quickly reach the maximum power of 14,000 horsepower, which can ensure continued successful takeoff and then go-around landing."
This chapter is not finished yet. Please click on the next page to continue reading the exciting content! The power of the engine is a bit too large. This is a disadvantage and an advantage. After all, taking off and landing on an aircraft carrier is very dangerous, and various accidents can happen at any time.
If something happens, the people inside the AWACS cannot be ejected like a fighter jet.
"Has the mapping and copying of the engine started?" Qin Tao asked.
At the beginning, he got ten of them, eight of which were used to equip four early warning aircraft, and the remaining two were intended for surveying and mapping. If the navy wanted to build one, it would still need a lot of them in the future. In addition to early warning aircraft, there must also be transport aircraft.
Anti-submarine aircraft, etc. At the same time, this engine is powerful and can also be used to replace other land-based transport aircraft.
"Mr. Qin, there are currently two types of sounds in the country. One is directly imitated by mapping, and the other is designed by oneself and improved with modern technology. It can be more powerful than this kind of engine." Mr. Chen spoke.
"There is no shame in direct mapping and imitation. If we can imitate it, we can improve it." Qin Tao said: "We don't have so much time to do self-research and design. Can we build it in ten years? By then, our domestic aircraft carriers will have started construction for two or three years.
We have a ship, we don’t have an engine, and we can’t produce an early warning aircraft, what should we do?”
Qin Tao is a firm believer in imitating surveying and mapping because he knows how much time will be wasted if he does his own research.
He simply didn't have the time to wait, and the army didn't have the time to wait either. Let's do the mapping and imitation first! Improvement is a matter for the future.
Just like the turbofan 15, copy it first and then improve it. Solve the problem of whether or not first and then talk about improvement!
"Mr. Qin is right, let's imitate it first." Wu Shengli also nodded: "We can talk about other things after imitating it. Just like our turbofan 15, it is now usable, and the turbofan 10 is still available.
I'm experimenting."
Comparing the two, we can see that Qin Tao was wise at the time and directly bought a complete set of Turbofan 15 technology. Now it has become the most reliable power for the J-32. Let’s take a look at the Turbofan 10 and the relationship between this engine.
As for the localization of the J-10 and J-11 fighters, they have not been finalized for a long time. Although they have been equipped on the twin-engine J-11 for test flights, it is said that there are too many problems to count.
Therefore, imitation is necessary.
"Yes, Leader Wu, President Qin, I will pass on your opinions." Duan Yi said: "Right now, this aircraft is being installed, and I can't invite you to see it inside. Otherwise, I will give it to you here.
Continue to introduce?"
"Has the mushroom tray been installed?" Qin Tao pointed at the top of the early warning machine
asked the big round disk at the bottom.
"Yes, the mushroom tray was installed three days ago. Now, we are mainly doing the finishing work of the mushroom tray and the installation of internal equipment."
At this moment, another person jumped out. He wiped his sweat, and then looked at Qin Tao and others with a smile.
"Mr. Wang?" Qin Tao looked at the people who came down in surprise: "Are you here too?"
"I have just been here a few days ago. During the test at sea a few days ago, I was also on the AWACS. Your J-31A performed very well. Our AWACS..." Mr. Wang said here
He stopped, glanced around, and then said: "Let's talk about our early warning aircraft. Due to the limitations of the airframe, its performance is definitely not as good as our Air Police 2000."
"That's for sure. Our navy doesn't expect its performance to be better than the strategic early warning aircraft." Qin Tao said: "Its main mission is to search for low-altitude flying targets and help the navy better respond to sneak attacks."
Mr. Wang nodded: "Yes, so when we designed it, we deliberately strengthened its low-altitude search capabilities. Of course, since it was installed later, we used the more advanced Godson-2, with the main frequency
It is taller, has more advanced manufacturing processes, and generates lower heat. Although its equipment compartment has a small capacity, its processing power has reached one-half of that of the Air Police 2000!"
In the past few years, Mr. Ni and the others have been working tirelessly. There is still a certain gap between the world's advanced level of Godson No. 1 and they rely on quantity. By the time Godson No. 2 has reached world synchronization, by Godson No. 2, it has reached world synchronization.
On the 3rd, it’s time to achieve transcendence!
At present, Godson-2 has not yet entered the market in large quantities, but many scientific research institutions and military products have begun to use this most advanced processor. Therefore, despite the small size of the early warning aircraft in front of you, its operational performance
Not weak!
"Mr. Duan, there is something wrong with our rotating shaft!" At this moment, a technician above shouted.
Zhao Ling was stunned by these words: "Isn't the radome of our Air Police 2000 fixed? Why does it actually rotate when it's on our carrier-based aircraft? This method has long been outdated, right?"
This sentence was just blurted out. After finishing it, Zhao Ling felt a little embarrassed: "I'm sorry, I didn't mean it, I just..."
"Our AWACS aircraft cannot be compared with land-based aircraft when it is put on the ship." Qin Tao explained to Zhao Ling: "Our land-based AWACS aircraft does not need to consider issues such as weight and power consumption, so it can
It doesn’t matter how much money is spent to install a three-sided phased array. However, if our carrier-based early warning aircraft is also equipped with a three-sided phased array, there will be a lot of stuff packed into the radome, the weight will also increase, and it will consume more power.
It’s even more astonishing. We made this choice only after making trade-offs.”
"Mr. Qin, how did you know?" Mr. Wang was very curious. He remembered clearly that after Qin Tao handed over the affairs of this stall to the relevant person in charge, he took over as the shopkeeper and had never seen it before.
"I analyzed it." Qin Tao simply replied.
"Yes." Mr. Wang nodded: "Mr. Qin's analysis is so right. The radar used by our carrier-based early warning aircraft really makes things difficult for us. We originally planned to design a three-sided phased array radar, but calculations
We gave up after the weight was exceeded. Although the search effect of the three-sided fixed radar was better, and the design of the airframe also provided us with sufficient margin, we were also afraid that if it landed, the landing hook would hook.
I caught the blocking rope, but the big plate on top flew off?"
If the large plate is too heavy, something like this may happen, even if they have calculated it well. If they continue to reinforce it, they will pay more structural weight.
