Chapter 257

However, the Dassault aircraft design software of Tengfei factory is not a military aircraft design software with higher redundancy.

There is no way to do this. After all, Tengfei factory is only a civil aviation factory for UAVs, not a military factory for military aircraft.

Even though the UAVs produced by Tengfei factory have been sold by H company as military products, the characteristics of low altitude, low speed and low power are no different or even lower than those of ordinary small civil aircraft.

Therefore, Liszt didn't give top configuration treatment when selecting the flight design software developed by Zhuang Jianye. In addition to Liszt's inherent limitation and control of Tengfei factory, Liszt couldn't provide higher version software.

Therefore, the Dassault aircraft design software in the hands of Tengfei factory can only carry out the structural design of aircraft with a speed of less than 300 km / h.

It's not impossible to design an aircraft with a speed of more than 300 km / h, but the aerodynamics indexes in the software do not support the simulation data analysis of such high-speed airflow. Therefore, even if you do it, it's just a fantasy and can't be applied to practice.

Because of this limitation, there is no analysis and modeling module for large structural gravity parts in the software of Tengfei factory. The reason is very simple. The speed below 300 km / h is a typical small aircraft field, which does not involve the design and manufacture of large structural gravity parts. Even if it is installed, it is also a waste, so the smart French simply deleted this part.

Of course, if Tengfei wants an aerodynamics database with a speed of more than 300 km / h and a large gravity structure module, the French are still very open in this respect. As long as you take the money and agree to their terms, you can.

But it's obvious that it's just putting your head out there and letting the French kill you.

In this regard, a few of the No. 10 project leaders who came to the field to investigate the flight design software of Tengfei factory were somewhat disappointed. However, what comforted them was that Dassault aircraft design software reserved a very open upgrade back door.

Obviously, it's for the sake of upgrading in the future and earning another sum of money.

The reason why they are so open is that the French think that they can't play with such high-end things.

In fact, it's true. Not to mention that the software programming language is not a big pass, let's say that the aerodynamics database with detailed data can't be found in the world several times.

The two superpowers, the United States and the Soviet Union, are no exception. However, they are all made for the purpose of fighting the world war. They are so high-end that they don't look up to France at all.

Britain and West Germany have the ability to rewrite the software. The problem is that they are still dissatisfied with their own aerodynamics. They managed to get a "windy" fighter and have to take it to the United States for wind tunnel tests. As a result, one fighter was turned into a fighter bomber by the two countries.

China has heard that it has a set of wind tunnel test equipment. If you look at the dilemma of the jian-6 flying all over the ground, the Jian-7 having no friends, and the jian-8 being three flat and four out of round, you can see that China's aerodynamics is at the level of the 1960s.

The United States and the Soviet Union don't like it; Britain and Germany don't have the strength; China is so backward that they can't even find a way out. What's the fear of France, which thinks it is the leader of the second echelon?

I just put the back door where you can't do it. On the contrary, you have to take money to upgrade. It's hard to describe the unspeakable superiority. Only the happy moaning can express the romantic pleasure.

Lister thinks the same way. After all, if he wants to upgrade from a speed of less than 300 kilometers per hour to the design of supersonic fighters and large airliners, he doesn't believe that a country that doesn't even have TV sets, refrigerators or even food can do this.

However, both Liszt and the French have forgotten one thing. Not all nations in the world choose to hold back in the face of difficulties, and not all nations choose to take things as they please in times of poverty. Perhaps most nations on this blue planet are like this, but there are always one or two exceptions.

And the Chinese nation is that exception!

In fact, as early as the 10th of last year, when the project team contacted the French to purchase their aircraft design software, they had already begun to demonstrate the feasibility of domestic independent research and development of relevant design software.

You should know that this kind of software is an essential thing in the field of future aircraft design, especially in the field of military aircraft. It is absolutely a good thing to improve efficiency and reduce cost.

In this case, the domestic natural to master, or let people choke on the design end, it is too hard.

However, at that time, the project team of No. 10 project encountered several difficulties in this aspect and could not make up its mind. First, the domestic computer software was still in the blank stage, and whether such a large software could be produced still needed further investigation.

Secondly, the digital storage of aerodynamic test data is also blank, and the systematic research is not enough, which leads to the lack of detailed Aircraft Aerodynamics in China.

Finally, due to the lack of relevant experience, we don't know where to start and how to promote it. At the same time, we should also consider whether this sub project will affect the progress of project 10.Because of the above reasons, the person in charge of the No.10 project team is very cautious about developing domestic flight design software.

However, when they saw the castrated original flight design software of Dassault, all their hesitations were swept away.

China has a complete test wind group, covering almost all fields from low altitude areas to ultra-high speed in outer space; in addition, the fighter bomber project of Xi'an Institute of Aeronautics and Astronautics also uses the flight design software of Dassault company of France.

Although it is only a sample level software, the software upgrade is locked, and it is unable to carry out the design of higher level aircraft, but its scope is up to double the speed of sound, and it has a certain large gravity structure design module.

With these two things, plus the castrated version of flight design software with open back door, the project team of project 10 has a complete set of buff bonus. If we don't do it, when will we do it?

You should know that the heads of several project teams of Project No. 10 are all people who survived from the 1950s and 1960s. They thought they could produce two bombs and one satellite when they wanted nothing. Now they have wind power group, samples from China Western Airlines Institute and take-off factory. I don't know how much better the conditions are than those of two bombs and one satellite.

Why not? It's done!
