Chapter 474

Director Zhao and Li Fang can't help but wonder where the advanced light tactical transport aircraft is? Why haven't you heard of it?

"I remember you didn't set up any other models except yun-6 and the plateau Eagle series derived from it?" Song Changzheng suddenly asked.

Zhuang Jianye has a brilliant smile: "the advanced light tactical transport aircraft scheme is just a new model made by our national aviation company, which is slightly larger than the current Yun 6 equipped with air force. The maximum take-off weight is between 16 and 20 tons, and the deadweight is about 6 to 9 tons..."

"Wait!" As soon as Zhuang Jianye was ready to go on, he was interrupted by Li Fang: "your parameter is basically the same as yun-7 and an-26, and the homogenization is very serious."

Song Changzheng also frowned and nodded: "the Navy and the air force were equipped with a batch of an-26 in the 1970s. Up to now, the overall age of the aircraft is not bad. Because of this, the northwest factory's yun-7 is very embarrassed. If you have another similar model here..."

Song Changzheng didn't say the following words, but he shook his head more helplessly than a thousand words. Director Zhao didn't say anything, but his dark face was full of worries. Just now, he thought that the headquarters head's inaction was very good. Could he turn to Xiaozhuang and they just fooled around in other ways?

"Heads, don't worry. Let me finish." Zhuang Jianye quickly explained with a smile: "our positioning of this advanced light tactical transport aircraft is not on the take-off weight and load, but on the range and consumption ratio, because the maximum range designed by us is not less than 5000 km, even if it is full of fuel, it also has a range of nearly 3000 km..."

"Maximum range 5000 km?"

Zhuang Jianye's words had just been interrupted by Li Fang, but this time Li Fang was not expressionless, but from his narrow eyes he could not hide his disbelief.

Song Changzheng also frowned deeply, pondered for a moment and shook his head: "the biggest voyage of 5000 kilometers..." Then he raised his eyes to Zhuang Jianye: "is it too exaggerated?"

That is to say, I have just seen the excellent performance of the d-50. Otherwise, Li Fang and song Changzheng would never be so cautious. They would turn around and leave without hesitation.

The reason is very simple. A light transport aircraft with a take-off weight of less than 20 tons and a range of more than 3000 kilometers is world-class. If you want to reach 5000 kilometers, that's the level of a medium transport aircraft with a take-off weight of more than 45 tons.

Among other things, the maximum range of yun-7, which has just been tested every two years, is less than 2000 km; the range of an-26, which was introduced from the Soviet Union in the 1970s, will only reach 2000 km under the condition of light load.

5000 km, that's the height that yun-8 can reach. Zhuang Jianye says that his advanced light tactical transport aircraft can fly to 5000 km. If yun-8 is still believed, but 20 ton light transport aircraft, even if they are fooled, they have to find a layman. They are all senior technical experts in the team. Tell them this

Li Fang and song Changzheng felt that Zhuang Jianye had been carried away by his d-50 achievements and began to brag about not paying taxes.

It's not just two naval experts. Director Zhao also thinks that Zhuang Jianye's data is a bit off the mark. Although director Zhao is not interested in aviation, many things in aerospace are interconnected, but he knows the way inside the plane, so he thinks that Zhuang Jianye's bluff is a bit big this time.

It's just different from Li Fang and song Changzheng who simply feel that Zhuang Jianye is overjoyed. Director Zhao has a little bit of hatred for his students. Even if he brags, he can't blow too much, can he? Just say 3000 kilometers. 5000 kilometers is a little unrealistic.

"Chief, please don't judge our advanced light tactical transport aircraft with old-fashioned ideas."

As a result, before Zhuang Jianye opened his mouth to explain, Qian Qiang suddenly opened his mouth in a tough tone, which made director Zhao and others feel stunned. What happened to Qian Gong?

Only behind Zhuang Jianye's bitter smile are all kinds of dark cool.

What's the matter? It's for small money, of course.

You should know that the plateau Eagle exported to Nepal, all of a sudden let the Lin Guanghua team in charge of aircraft design, the Pengchuan team in charge of production, the Wei Guangping team in charge of equipment improvement and the song Yanan team in charge of materials make a lot of money.

Only Qian Qiang, who is in charge of the engine, got a big zero, because the highland eagle in Nepal uses the turboprop engine of the United States instead of the D-series of Tengfei aviation power.

Fortunately, pan Xu later reached eight sets of CCHP units with Nepal, which finally gave Qian Qiang's gas turbine power plant team a piece of the cake,

but Qian Qiang was still very uncomfortable. The reason is very simple: aircraft is a high-end industry, and the main business of Tengfei aviation general company is the top existence; CCHP unit is just Tengfei aviation A subsidiary business of the head office, no matter how much it earns, can not match the dominant position of the aircraft.

In other words, there is an invisible disdain chain among the businesses of Tengfei airlines. Naturally, the aircraft is at the top of the disdain chain, and it is the most valued. The proportion of sales share is also the largest, so it is appropriate to crush other businesses.Qian Qiang's appearance is light and cloudless. In fact, he is envious to death, especially song Yanan's stubborn woman. This makes Qian Qiang not only envious, but also a little envious. When he was in the University of Western Airlines, he was more successful than song Yanan. How can he come to take off Airlines?

That's not true. In case the old superiors, old colleagues and old classmates know where to put their faces? So some time ago, Qian Qiang suddenly let go of the scholar's reserve and pestered Zhuang Jianye with a dead face. He patted his chest and promised that he would use their turboprop engine to make sure it was OK.

Both yun-6 and highland hawk are face products established by Tengfei airlines. Even if they have confidence in their own products, Zhuang Jianye still feels cautious. What's more, yun-6 and highland hawk series are single engine turboprop aircraft with great limitations. Therefore, Zhuang Jianye will never use them until the reliability of his own products is fully recognized Go to Yun 6 and highland eagle.

However, it's not a good thing to let Tengfei aviation power do this. Under the leadership of Zhuang Jianye, a twin engine turboprop light transport aircraft plan was officially released.

Because of the dual engine, the safety of the D-series has been guaranteed to a certain extent. Even though the overhaul interval and service life of the D-series of Tengfei aviation power are not as good as those in the United States or the United States, they are barely promoted to most of the mission requirements. More importantly, the D-series has finally got its own platform.

The happiest thing about this is Qian Qiang. Not only does he step up the development of supporting turboprop engines, but he will also call Lin Guanghua to urge him to speed up the design. His style is even better than that of the chief engineer.

As a result, the treasure he valued so much was questioned. Qian Qiang might be able to sit still. Without saying a word, he went to another filing cabinet, turned it over twice, took out a book, and handed it to Li Fang and others: "this is the fuel consumption data of several turboprop engines, none of which is more than 0.308 kgkwh."

"So low!" Song Changzheng's eyes were wide open, and he just looked at Qian Qiang.
