Chapter 676: Early warning aircraft can also be matched with high and low levels
The early warning aircraft does not need to load large cargo at all. The original tail hatch is naturally sealed directly. By the way, a lot of control and loading mechanisms are omitted. While reducing the take-off weight as much as possible, it can also be regarded as maintaining longitudinal balance. Made some contributions——
The T-shaped antenna added during the modification process and the resulting raised tail made the rear half of the aircraft a bit overweight.
Generally speaking, when faced with this kind of situation, the main balancing method is to adjust the fuel distribution in the aircraft. However, the range of the Y-8 air-tight model is already ridiculously short. If the fuel is further affected, the actual performance of this early warning aircraft will be reduced. There is no need to count on efficiency...
As a factory airport, the comfort configuration is naturally average.
After hearing the chief say he wanted to get on the plane, someone quickly brought an ordinary metal ladder and set it up at the cabin door on the right side of the plane.
At the same time, a power supply truck had been parked on the other side. Several ground staff got out of the truck and began to connect power to the aircraft.
Fortunately, everyone's legs and feet at the scene were pretty good, at least they wouldn't fall down even if they climbed up a ladder.
Since there was no sunlight and there was no heating when the plane had not started, it was actually colder inside the cabin than outside.
Wang Xiaomo, who was a bit older, couldn't help but tighten her coat.
As a military transport aircraft designed in the 8s, the cabin of the Y- is relatively narrow, so only a row of operating desks is arranged on the right side.
Fortunately, the plane itself is long enough, so the seats are quite sufficient.
The leader walked back and forth twice in the cabin, then sat on one of the seats and gently moved the trackball and keyboard fixed on the table.
Two years ago, when Chang Haonan and Wang Xiaomo talked about the early warning aircraft, in addition to the aircraft itself, they also talked about some design details.
For example, do not use an ordinary chair at the operating station, and do not place an ordinary keyboard and mouse on the operating table.
After all, an early warning aircraft is an airplane, and various situations may occur while flying in the sky.
In case of any strong convective weather or even malfunction or damage, the fewer things that cannot be fixed and can fly around in the cabin, the better.
These details may seem ordinary, but for China, which is seriously developing an early warning aircraft for the first time, it is easy to overlook.
In particular, Wang Xiaomo, who is responsible for the research and development of in-cabin equipment, is not an expert in aviation technology, and some of the experience of ground radar stations cannot be copied to the sky.
At that time, he also praised Chang Haonan's thoughtfulness.
But in fact, these are the lessons learned from the early days of the Air Police 200 project in the previous generation...
"Can this console be turned on now?"
The leader turned his head slightly and asked the people behind him.
"The operation terminal can be turned on, but the radar is not working yet."
Wang Xiaomo replied:
"In order to reduce the risk, the current array will be removed during the first flight and replaced with a counterweight of the same shape and weight, so the radar is not yet connected to power."
The time spent by the 14th Institute to produce this radar was almost longer than that of the 182nd Factory to produce the following aircraft, so naturally it is very precious.
Although the risk of the first flight is very small according to the wind tunnel test results, it cannot be guaranteed to be foolproof after all.
As soon as he finished his answer, another technician next to him turned on the power of the terminal cabinet.
In this era, even Windows
Therefore, the interface is not very attractive. After the self-test, a schematic diagram showing distance and orientation appeared on the CRT monitor, but there was only a light spot in the middle.
Several English prompts flashed on another screen nearby.
The chief spoke foreign languages very well and understood what it meant when the radar self-test failed.
"There are many people here who are good at foreign languages, but for the radar we developed ourselves, is it possible to change the operating interface into Chinese?"
He didn't directly give the order. After all, he was also a technical person, so he knew that at this time, it was not necessary for an outsider to guide an expert.
"The software is not difficult, but the number of bytes occupied by Chinese characters is a bit large. In order to ensure stability, the performance of the early warning aircraft operating terminal is far inferior to that of ordinary PCs, so we still use English for now."
Wang Xiaomo quickly explained:
"But when the hardware level improves in the future, it will not be difficult to change. We will strive for..."
As soon as he said this, he was interrupted by the chief waving with a smile on his face:
"I'm just asking casually, and there is no need to affect the normal research and development progress."
Wang Xiaomo breathed a sigh of relief.
Although he is considered well-informed, he is still a little nervous in this environment.
"Since there is no problem with the performance of the radar, what about the aircraft itself?"
Fortunately, the chief did not keep putting pressure on him, but quickly turned his attention to Liang Shaoxiu on the other side.
Although the latter was well prepared, his heart sank when he heard this question.
After all, there are actually only two types of early warning aircraft using phased array radars in the world today, namely the Falcon and the Swedish Erieye. The radar of the Air Police 200 benefits from the advantage of being a latecomer, even if it is not as good as those two. It can definitely be called the top three in the world.
In comparison, the Yun8 platform is a bit embarrassing...
Of course, no matter what, the question still has to be answered:
"The improved Y-8 air-tight platform has several key design indicators that are improved compared to the original Y-8C. After the modification is completed, it is expected to reach a maximum level flight speed of 580km, a range of 2000 kilometers and about 4.5 hours. Leave time blank.”
For the special machine platform, these three indicators are important.
It's a pity...it's really not that good.
The air-tight platform itself has a maximum unloaded range of only 3000 kilometers. Now it is equipped with a mission load with a total weight of more than 5 tons, plus an antenna with huge induced resistance and a large vertical fin, and it can still maintain more than half of the range. Liang Shaoxiu has reached the limit of his abilities.
"That is to say, in terms of flight performance, there is indeed a certain gap between it and the ring project."
The leader used a declarative tone.
In fact, when the numbers are here, there is really nothing to ask.
Liang Shaoxiu suddenly didn't know what to contact.
He couldn't tell the entire development process of the flying platform in front of the big leaders.
But at this time, Ding Gaoheng, who had been following him without speaking a word, came to his rescue:
"Chief, the Ring Project is a strategic transport aircraft platform after all. It is destined to have advantages in terms of range and speed. The take-off weight of the Y-8 is only one-third of the IL-76, so it is normal that it cannot compare."
"Moreover, our domestically produced early warning aircraft cannot only be limited to the Air Police 200 model. When we planned to produce mainline passenger aircraft in Shanghai, Comrade Haonan and I considered the possibility of using the domestically produced C909 platform to modify the early warning aircraft in the future. "
Hearing this, the chief's eyebrows moved, obviously he was somewhat interested in this.
Although Ding Gaoheng is not an aviation professional, he has heard Chang Haonan draw cakes for him many times. Upon seeing this, he quickly continued to add details:
"Although the take-off weight of the C909 is lower than that of the IL-76, it is still a passenger aircraft. The basic model has a range of about 6000 kilometers, and the luggage compartment space under the floor can be converted into a fuel tank."
"Tupolev has carried out similar upgrades before, which can increase the range to more than 9000 kilometers. Even taking into account the impact of load and radar antenna, it is enough to provide 8-10 hours of available mission time."
"Moreover, for commanders and fighters who perform long-term missions in the air, the comfort of a passenger aircraft platform is much better than that of the IL-76, a military transport aircraft."
This rhetoric is obviously an understatement, but whether it is a domestic phased array radar or the C909 passenger aircraft that is already building a factory and preparing for production, it is obviously not something that can be seen or touched.
So this cake can at least smell.
Wang Xiaomo, who was next to him, saw this and quickly picked up the conversation:
"Our radar research and development is also in line with this. In addition to the T-shaped array currently used by the Air Police 200, there are also fixed three-sided arrays in the disc-shaped radome, and even back-to-back rotatable dual-band two-sided array radars. Simultaneous research and development should be able to match the progress of domestic passenger aircraft platforms.”
When persuading superiors to do something, pay attention to one point.
The higher the level of leadership, the more issues and aspects to consider when making decisions.
It’s enough to say what you say, and you must not keep pushing.
Therefore, after the two of them finished speaking, the cabin fell into silence again.
Only the buzzing sound of the cabinet cooling fan surrounded everyone's ears.
And in fact, since the chief will specially arrange this trip, it means that he already has some tendencies in his heart.
A personal inspection merely eliminates some concerns.
There was no need for them to say much more.
We are about to enter a stage where the content is relatively sensitive. I have re-registered a fan group at the bottom of the book details page. If there are chapters that I really cannot post, I will post them in the group...
