Director Zhao and Li Fang couldn't help but be stunned when they heard this, what kind of advanced light tactical transport aircraft plan? Why haven't they heard of it?

"I remember that you don't have any other models except for the Yun-6 and the Plateau Eagle series derived from it, right?" Song Changzheng suddenly asked.

Zhuang Jianye smiled brightly: "The advanced light tactical transport aircraft program is just a new model made within our Tengfei Aviation Corporation, which is slightly larger than the Y-6 that is now equipped with the Air Force, with a maximum take-off weight of between 16 and 20 tons and a carrying capacity of about 6 to 9 tons......"

"Wait!" Zhuang Jianye was about to continue, but was interrupted by Li Fang: "Your parameters are basically the same as Yun 7 and An-26, and the homogenization is very serious. ”

Song Changzheng also frowned and nodded: "The Navy and Air Force were equipped with a batch of An-26 in the seventies, and the overall age of the aircraft is not bad until now, and because of this, the Y-7 of the Northwest Factory looks very embarrassing, if you have such a similar model here......"

Song Changzheng didn't say the next words, but the helpless shaking of his head was worth a thousand words, Director Zhao didn't say anything, but his dark face was full of worry, just now I felt that the inaction of the head of the headquarters was very good, could it be that Xiaozhuang turned his head and they were nonsense in other aspects?

"Chiefs, don't worry, listen to what I'm saying. Zhuang Jianye hurriedly explained with a smile: "Our positioning of our advanced light tactical transport aircraft is not in the take-off weight and load, but in the range and consumption ratio, because the maximum range we designed is not less than about 5,000 kilometers, even if it is fully fueled, it also has a range of nearly 3,000 kilometers......"

"Maximum range 5000 km?"

Zhuang Jianye's words were interrupted by Li Fang again halfway through his words, but this time Li Fang was not expressionless, but from the small eyes that could not be concealed disbelief.

Song Changzheng also frowned deeply, pondered for a moment and shook his head: "The maximum range of five thousand kilometers ......" and then raised his eyes to look at Zhuang Jianye: "Isn't it too exaggerated?"

This is what I have just seen the excellent performance of D-50, otherwise Li Fang and Song Changzheng would never be so cautious, and they would not hesitate to 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 can reach a range of more than 3,000 kilometers, and if you want to reach 5,000 kilometers, it is the level of a medium-sized transport aircraft with a take-off weight of more than 45 tons.

Not to mention anything else, the Y-7, which has just been tested every two years, has a maximum range of less than 2,000 kilometers, and the An-26 imported from the Soviet Union in the 70s will only reach a range of 2,000 kilometers with a light load.

5,000 kilometers, that is the height that can only be reached by the 8, Zhuang Jianye opened his mouth and said that his advanced light tactical transport aircraft can fly to 5,000 kilometers, if the 8-level is still believed, but the 20-ton light transport aircraft, even if it is fooled, it is necessary to find a layman to fool, they are all senior technical experts in the army, tell them this......

Li Fang and Song Changzheng felt that Zhuang Jianye was carried away by the D-50 score just now, and began to brag that he would not pay taxes.

Not only the two naval experts, Director Zhao also felt that the data exposed by Zhuang Jianye was a bit outrageous, although Director Zhao was not interested in aviation, but many things in aerospace were interconnected, but he also knew the doorway in the plane, so he felt that Zhuang Jianye's cowhide this time was a bit big.

It's just that unlike Li Fang and Song Changzheng, who simply felt that Zhuang Jianye was a little carried away, Director Zhao had a little bit of a teacher's hatred for students, and even if he bragged, he couldn't brag about it, right?

"Chiefs, please don't judge our advanced light tactical transport aircraft with the old-fashioned notions of the past. ”

As a result, before Zhuang Jianye could explain, Qian Qiang on the side suddenly spoke, and his tone was hard, which made Director Zhao and the others stunned, and said in their hearts, Qian Gong, what's wrong?

Only behind Zhuang Jianye's bitter smile on the surface is all kinds of wow-stricken.

What's wrong? For a small amount of money, of course.

You must know that the export of Plateau Eagle to Nepal suddenly made the Lin Guanghua team in charge of aircraft design, the Peng Chuan 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's team, which was in charge of the engine, got a big zero, because Nepal's Plateau Eagle used American turboprop engines, not the D-series of Take-off Aviation Power.

Fortunately, Pan Xu later reached eight sets of combined cooling\heat and power generation units with Nepal, which finally gave Qian Qiang's gas turbine power unit team a piece of the pie.

But it still makes Qian Qiang feel very uncomfortable, the reason is very simple, the aircraft is a high-end industry, the main business of the Tengfei Aviation Corporation, is the top existence; the combined cooling\heat and power generation device is only an incidental business of the Tengfei Aviation Corporation, no matter how much you earn, it is not comparable to the dominant position of the aircraft.

In other words, there is a chain of contempt that cannot be seen or touched between the various businesses of Tengfei Aviation Corporation, and the aircraft is naturally the top of the chain of contempt, not to mention the most valued, and the proportion of sales share is also the largest, properly crushing other businesses.

Qian Qiang is light on the surface, but in fact, he is envious to death, especially Song Yanan, the stubborn woman who actually surpasses herself in this regard, which makes Qian Qiang not only envious, but also a trace of jealousy, when he was in Xihang University, he had higher achievements than Song Yanan, how could he come to Tengfei Aviation Corporation?

So some time ago, Qian Qiang suddenly put down the reserve of a scholar, pestered Zhuang Jianye with a dead face, patted his chest and promised that with their turboprop engine, it would be no problem.

Whether it is Yun 6 or Plateau Eagle, all belong to the face of the Tengfei Aviation Corporation to establish a reputation for products, even if you have confidence in your own products, Zhuang Jianye still feels cautious, not to mention that Yun 6 and Plateau Eagle series are single-engine turboprop aircraft, the limitations are very large, so before the reliability of its own products is not fully recognized, Zhuang Jianye will never apply it to Yun 6 and Plateau Eagle.

However, it is not a matter of letting Tengfei Aviation Power do this cold bench, so under the leadership of Zhuang Jianye, a twin-engine turboprop light transport aircraft scheme was officially released.

Because it is a double engine, there is a certain guarantee in safety, so even if the D series of Tengfei Aviation Power does not have the overhaul interval and service life of the United States or so much, it is barely promoted to most of the mission requirements, and more importantly, the D series finally has its own platform.

The happiest thing about this is Qian Qiang, not only is he stepping up the development of a supporting turboprop engine, but he will also call Lin Guanghua when he has nothing to do, urging him to hurry up the design, which is more than the chief engineer.

As a result, the treasure that he valued so much was questioned, Qian Qiang might be able to sit still, without saying a word, he walked directly to another filing cabinet, flipped through it twice, took out a notebook, and handed it to Li Fang and others: "This is the data on the fuel consumption rate of several turboprop engines, and none of them exceed 0.308 kg \ kW per hour." ”

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