After all, the European market is a long-term plan, and the most important thing for Chang Haonan at the moment is to deal with the few projects at hand.

Fortunately, for him now, it is not particularly difficult to help Liang Shaoxiu complete the overall design of the Air Police 200.

Although the Air Police 200 has only been officially approved for less than a month, the aerodynamic and structural design of this aircraft has actually started after Chang Haonan first proposed the plan of the Yun-8 platform and T-shaped antenna.

At that time, Liang Shaoxiu was mainly led by Liang Shaoxiu to promote the factory-affiliated design office of Factory 182.

Many structural and balancing problems have been solved, and only some key problems that are difficult to solve with traditional tools and means remain.

For example, when it comes to the calculation details of antennas and turboprop engines.

These parts are typical dirty models, i.e., models with irregular surface shapes and a lot of bending, making it difficult to parametrically model.

But this happens to be what Chang Haonan and TORCH Multiphysics are good at.

As far as the aerodynamic design is concerned, the T-shaped antenna used is a relatively simple type, and the damage to the original aerodynamics, especially the longitudinal stability that is more difficult to deal with, is far less than that of the disc antenna, and even to some extent smaller than the conformal array antenna like Ferkang.

The only concern may be the large antenna area along the axis of the fuselage, and the resulting heightened tail and increased pelvic fin, which makes the entire aircraft more affected by crosswinds.

In fact, this does not solve the problem at the root and even makes it impossible for the T-shaped antenna to be mounted on a small platform (because the large area is the advantage of the T-shaped antenna).

Fortunately, although the platform of Yun 8 is very bad from Chang Haonan's point of view, the 35-ton empty weight volume is definitely enough, and after specially increasing the area of the vertical tail action surface, this seemingly exaggerated antenna finally only caused the air police 200 to reduce the wind requirements in the take-off and landing process by about 2m/s.

About a quarter of a force force wind.

Quite acceptable.

In the supercomputer operation room of Beijing Aviation University, Wang Xiaomo stood beside Chang Haonan, looking at the 3D model on the screen in front of him, and the simulation calculation results flashing by rows, and said with some emotion:

"Even a year ago, it was hard for me to imagine that the comrades of the aviation system could come up with a new aircraft in less than half a year to ......"

"Is this...... On the one hand, the platform itself is ready-made, and on the other hand, it is also dependent on the antenna provided by you to be friendly to our work, so the design is not too difficult. ”

Chang Haonan said and hit the enter key to save the data and the model together.

It's not that he compliments the other person.

The high-performance radar design and packaging scheme provided by Wang Xiaomo ensures the relative lightweight of the antenna itself, which does save a lot of structural design work for the aging Y-8 platform.

Although the Y-8 has a maximum load of 20 tons on paper, any transport aircraft, especially tactical transport aircraft and passenger aircraft, is designed to be evenly loaded throughout the cargo compartment, rather than a large centralized load – a matter that would only be considered by the An-124/C5 or at least the An-22.

If the weight of the antenna itself is too large, it is necessary to additionally reinforce the structure of the Yun-8, in that case, it will involve too many problems involving the whole body, even Chang Haonan cannot solve it in a short time.

The current transformation mainly only needs to consider aerodynamic changes, and the difficulty is much lower.

It's the beginning of a virtuous circle.

It's true that the amount of water a barrel can hold depends on how long the shortest board is.

But if the length of the other boards is okay, or even slightly exceeded, then the barrel can still be filled with more if it is tilted in one direction that has no shortcomings.

The Air Police 200, which is almost completely different from its previous life, is the advantage of using the radar antenna design to make up for the shortcomings of the Y-8 as a carrier aircraft to a certain extent.

Although it is definitely better to directly change to a reliable platform, it is already good in the case of urgent use at the moment.

Liang Shaoxiu, who was standing behind Chang Haonan, pushed his glasses:

"What the hell is a permanent worker...... If it is left in our factory, I am afraid that it may be delayed for a year or two for these few small problems, and if the project schedule is delayed, then my sin will be great. ”

"Liang Gong, don't be too arrogant."

Chang Haonan turned his head and motioned for the other party to start packing the data files, and comforted at the same time:

"Engage in engineering, or highlight a step-by-step, you have this experience, and you will be proficient when you do other projects in the future, the design office of the 182 factory was only a small unit responsible for copying models before, and now it can gradually undertake the design task, which is already a very fast progress."

Liang Shaoxiu sat in front of the computer, began to process the stored engineering files, and then sighed:

"I'm still a little scared......"

"Seeing that other fraternal units are making rapid progress one by one, and the third-generation aircraft, passenger planes, and helicopters are booming, even Guihang, which has always been with us in the past, has recently come up with a new model of training aircraft, and a few days ago a comrade from our factory went on a business trip to Zhucheng, and I heard that they are about to build even the front fuselage."

Chang Haonan didn't want to say that Guihang's trainer plane was also his own handiwork to some extent, but when he heard the last sentence, he almost subconsciously spoke:

"They're moving so fast?"

You must know that Sun Huizhong only went back last month.

Of course, he knows that in the previous life, Guihang also set a speed record in the process of producing FTC2000G - 9 months from design to the first flight, and 4 months from the start of construction to the first flight.

The production progress of the prototype is broadcast live almost every day on the official account.

But when you really feel it intuitively, it's still quite shocking.

It's a new plane.

And that's Guihang, Yunma Factory.

It's the worst place in the country's aviation system.

A month to get to the front fuselage is about to roll off the assembly line, and it is not too much to say that it is a miracle.

"It's really ...... very fast"

Liang Shaoxiu just said half a sentence before he reacted:

"Wait, do you know about this training aircraft project?"

"Uh......"

This question made Chang Haonan speechless for a while:

"It's better to say that this model was handed over to them by me, and it is nominally the technical verification and project supporting of Project No. 10."

“……”

“……”

Wang Xiaomo and Liang Shaoxiu looked at Chang Haonan almost at the same time, revealing a difficult expression.

It's all you......

After a long while, Liang Shaoxiu reopened his mouth and explained:

"I heard that Yunma Factory got an appropriation and paid the first half of the year's salary, and there was no mention of layoffs, so all the employees took the initiative to work in three shifts, eat and live in the factory, and worked day and night for a month."

"In addition, Guizhou Province also intends to support the high-end manufacturing industry in the province, so the provincial party committee personally takes command to provide logistics support, in short, the position is quite exaggerated......

It makes sense.

After all, everything is afraid of comparison.

Surrounded by all kinds of layoffs, the relocation of the whole factory and even bankruptcy and bankruptcy, they not only have a stable job but also pay wages, and they have to play with their lives on anyone.

The engineering files in the computer are actually not very large, but due to the file transfer speed of this era, the progress bar only jumped about two bars during the time when several people were chatting.

Another few minutes of silence.

"Permanent worker."

In the end, it was Liang Shaoxiu who broke the silence:

"Do you think the Air Police 200 has a chance to build a full-state prototype by October '99?"

Saying this point in time, it is obvious that he has an idea.

According to the requirements of the 9910 project, the military parade does not need to be really finalized, in fact, there are a lot of equipment that is still in the prototype stage for each military parade.

But you have to at least make sure that the technology is mature.

Especially aviation units.

If the ground equipment fails, there can be a backup, and it is a great loss to lose someone, and if the plane fails, it is a big deal......

"If you want me to say, it's not hopeless."

Chang Haonan touched his chin and thought for a while, and added:

"I mean hopeful."
