Chapter 676: The early warning aircraft can also be matched with high and low configurations
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 eliminated. It may not only reduce the take-off weight, but also make some contribution to maintaining longitudinal balance -
The T-shaped antenna added during the modification process and the subsequently raised tail made the rear half of the aircraft Some are a bit overweight.
Generally speaking, when faced with this kind of situation, adjusting the fuel distribution in the aircraft is the main balancing method. However, the flight range of the Y8 air-tight model is already ridiculously short. If the fuel is further affected, , then there is no need to count on the actual effectiveness of this early warning aircraft...
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 car and began to connect power to the aircraft.
Fortunately, everyone's legs and feet were pretty good, at least they didn't fall down even on the ladder.
Due to the lack of sunlight and the fact that the plane had not started, there was no heating, so 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 1950s, the cabin of the Y-8 is relatively narrow. Therefore, 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 chief 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 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 serious about developing 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. 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 early experiences and lessons of the Air Police 200 project in the previous life...
“Can this console be turned on now?”
The leader turned around slightly and asked the people behind him road.
“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."
For production purposes, the 14th Institute This radar took almost longer than the 182 Factory to produce the following aircraft, so it is naturally very valuable.
Although according to the wind tunnel test results, the risk of the first flight is very small, 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.
A few English prompts flashed on another screen next to it.
The chief speaks foreign languages very well and understands that it means the radar self-test failed.
“There are a lot of 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 did not give a direct order. After all, I have a technical background, and I know that at this time, it is 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:
“However, when the hardware level improves in the future, it will not be difficult to change. Let’s strive for...”
As soon as he said this, he was waved away by the chief with a smile on his face. Broken:
"I'm just asking casually, it doesn't have to affect the normal research and development progress." Wang Xiaomo breathed a sigh of relief.
Although he is well-informed, he is still a little nervous in this environment.
"Since there is no problem with the performance of the radar, how 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 Y8 The current key design indicators of the air-tight platform have been 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 2,000 kilometers, and a flight time of approximately 4.5 hours.”
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 3,000 kilometers. Now it is equipped with a mission load with a total weight of more than 5 tons, coupled with an antenna with huge induced resistance and a large vertical fin, it is also Being able to save more than half of the voyage is already the limit of Liang Shaoxiu's ability.
"In other words, in terms of flight performance, there is indeed a certain gap with the ring project."
The leader used a declarative tone.
Actually, when the numbers are here, there is really nothing to ask.
Liang Shaoxiu suddenly didn't know what to contact.
He can'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 beside him without speaking, came to his rescue:
“Chief, the Ring Project is a strategic transport aircraft platform after all. In terms of indicators such as range and speed, It is destined to have an advantage. The take-off weight of the Y-8 is only one-third of the IL-76, so it is normal for it to be inferior.”
“Moreover, our domestic early warning aircraft cannot only stay at 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 early warning aircraft in the future.”
Upon hearing this, the chief's eyebrows moved, and he was obviously somewhat interested in this.
Although Ding Gaoheng is not an aviation professional, he has heard Chang Haonan give him a picture many times. Seeing this, he quickly continued to add details:
"Although the take-off weight of the C909 is not It is lower than the IL-76, but it is basically a passenger aircraft. The basic model has a range of about 6,000 kilometers, and the luggage compartment space under the floor can be converted into a fuel tank. "
" Tupolev. Similar upgrades have been carried out before, which can increase the range to more than 9,000 kilometers. Even taking into account the impact of load capacity and radar antenna, it is enough to provide an available mission time of 8-10 hours. "
"Furthermore, For commanders and fighters who perform long-term missions in the air, the comfort of the passenger aircraft platform is much better than that of the IL-76 military transport aircraft.”
This rhetoric is obviously painting a cake, 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, the disc The fixed three-sided array in the radome and even the back-to-back rotatable dual-band two-sided array radar are also being developed simultaneously, and the progress should be able to match the progress of the domestic passenger aircraft platform. "
Advise superiors to do it. For something, pay attention to one point.
The higher the level of leadership, the more issues and aspects to consider when making decisions.
As long as you do what you say, 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 surrounds 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 is 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...< br>
