Chapter 260

In the face of this situation, Zhuang Jianye really has nothing to say.

It can not be said that domestic aero-engine research and development units and manufacturers do not work hard and forge ahead, but the idea of seeking perfection is everywhere.

After all, it's human nature to pursue higher, faster and stronger. What's more, the high thrust aeroengine is the crystallization of all human industrial wisdom. With it, the performance of fighter can be better. With it, large transport planes and bombers can fly in the sky. With it, large civil aircraft can fly across the ocean.

Of course, if we can complete it, the participating technicians will get higher honor, and the leading officials will get faster promotion.

What can a small turbine gas power plant below 1000 kW do? Even if the superior leaders come to inspect, they are embarrassed to put it out. It's so small and the power is so low. If the leader asks, what kind of plane can you put in this thing, it's embarrassing to say.

In addition, the open attitude of foreign countries towards the turbine gas power used in aircraft auxiliary power plant has also prompted domestic units to become careless in this field.

In particular, with the introduction of Boeing, McDonnell Douglas and other new large wide bodied airliners, the auxiliary power unit has also entered the country in the form of spare parts.

For example, the auxiliary power unit of model-36 aircraft on six Boeing-737 aircraft just imported by civil aviation is favored by Northwest Institute for its stable performance and super first-class high-altitude starting ability. It is applied to the improved model of yun-7 and becomes the latest auxiliary power system of yun-7.

As for fighter planes, China adheres to the rough style of the Soviet Union in the 1950s and 1960s, and the concept of auxiliary power is not clear. In addition, the airborne equipment is simple and basically mechanical instruments, and the requirements for the airborne power system are not prominent, so the auxiliary power only stays on starting the main engine.

As a result, it is usually very small, with a maximum of only 15 kg. With the limitation of materials and structure, the power is not very large.

Therefore, domestic fighters often have to be equipped with ground support equipment such as power supply or gas supply in the airport. The reason is that there is no independent auxiliary power unit for power supply and gas supply on the J-6 and J-7 fighters, which indirectly increases the burden of ground service.

However, due to different operational concepts and tactical composition, the army seems not to care about this. It was not until the emergence of the j-20 in the 21st century that this idea was completely changed and APU auxiliary power unit was installed inside the aircraft.

The reason for this is very simple. APU is a set of self-contained small engine which does not rely on any external energy.

When the main engine does not work, APU can provide power, gas, hydraulic and other energy to the aircraft. It can improve the self-sufficiency and maintenance support of the aircraft, extend the service life of the main engine and reduce the maintenance cost of the whole life of the aircraft without the support of ground equipment.

When the engine fails in the air, or when the power supply or hydraulic system fails, APU can provide auxiliary energy such as power supply and hydraulic system, and assist the engine to start quickly in the air, so as to improve the safety and flight ability of the aircraft.

However, this is the last word. Now the domestic aviation industry, especially the army, has not paid enough attention to this aspect.

Therefore, the t-62t, which Zhuang Jianye brought in with great efforts, has completely become a chicken rib. It's because my grandfather doesn't love me and my uncle doesn't love me. Of course, if Liszt can bring in the model-36 according to Zhuang Jianye's idea, the effect will be better. After all, this auxiliary power device is used on Boeing and McDonnell Douglas airplanes of civil aviation, and it can be a little light.

However, the effect will not be too great. After all, the new wide bodied airliner of civil aviation has its own maintenance support system. Tengfei factory used to learn how to do it, and it is estimated that it will be beaten by others.

In a word, in a word, the introduction of APU is a loss business.

"Director Zhuang Xiaozhuang... "

Just when Zhuang Jianye was hesitating because of the gas turbine power plant, the sound from the phone finally made him come back to himself: "er Excuse me, Professor Qian. I was a little distracted just now. You said... "

When he heard Zhuang Jianye's reply, Qian Qiang was relieved. He was really afraid that Zhuang Jianye would not be able to bear any good or bad things. Millions of dollars would fall down, and he could not even see a water flower. He could not bear to put it on anyone.

What's more, turbine gas power is not something that can be seen in one or two years. Let alone other things, we can see from the development of domestic aviation jet power in recent years. It has been more than 30 years since the founding of the people's Republic of China. Apart from several jet engines that were successfully imitated by the Soviet Union only after providing drawings and a full set of technical data, how many models have we developed?

Even the country is like this, let alone an enterprise.

So Qian Qiang frowned and hesitated for a moment, but he still said, "Xiaozhuang, no, let's stop jet power research. It's too demanding and too expensive. If it goes on like this, I'm afraid the factory will not be able to hold on."

Zhuang Jianye holds the phone in one hand and rubs his face vigorously in the other. He is also puzzled in his heart. From master Ju's start of jet power test to now, Zhuang Jianye has invested no less than ten million yuan and got nothing but a pile of scrapped parts.The loser doesn't have such a way to lose. It seems to be a good choice to stop. It's not only a bad worry, but also millions of money can be saved a year.

But if it really stops, the huge civil aircraft market in the future will not be mentioned. The APU on the fighter plane is a huge cake. In addition, the EPU (ground power unit) derived from APU is also widely used in electric power, metallurgy and chemical industry.

You don't have to go abroad to compete with other giants for the market. In the next few decades, the domestic development will be enough for the factory to make a lot of money.

As for the small turbojet engine and small turbofan engine of the tubeless APU, they are the best power for high-performance UAV, anti-ship missile and cruise missile. If the technology is mature and a little larger, they can become the main power module of the trainer and even the business aircraft.

This is a very clear technological development route, and it is also a broad road full of gold. Is it to save money for immediate interests now, or to continue to burn money for a lot of money tomorrow

"Go ahead, add another 2 million yuan to the total cost of this year, and raise it to 8 million yuan in the first half of the year. I will inform the accounting department to increase the amount of payment in the second half of the year. However, Professor Qian, I would like to add that is reliability. No matter we imitate the t-62t of the United States or innovate on its basis, reliability must not be worse than theirs!"

Zhuang Jianye finally clenched his teeth and said the final decision. Qian Qiang and Yan Tiancheng on the other end of the phone were relieved. Qian Qiang immediately said, "don't worry, director Zhuang, we will live up to your trust."

"Good!"

Zhuang Jianye nodded, then chatted a few words, and then put down the phone. After that, the whole person leaned back in his chair just like hollowing out. Since he was a loser, he was completely defeated. He couldn't smash it for a few more years. He couldn't even smash a flower.

But now the most important thing is to make money. TM, Liszt, why can't we have more dro drones? They are not only consumables, but also have a good profit margin

……

Liszt, who lives in New York City, has the same idea. Unfortunately, not everyone can see the value of the "attacker" UAV just like South Africa, because they prefer the "attacker" to be a missile rather than a UAV that no one understands.

So Liszt would like to go to the battlefield in person and let those guys who are eager for "attackers" to be missiles open their eyes and have a look. UAVs are thousands of times sharper than the missiles they imagined.

But Liszt, who is in New York, can't realize this wish. However, vesberg, who returned to South Africa from the United States and then re entered Angola from South Africa, can do it with his hands raised.

Because at the moment, he is driving a battalion of the Angolan Union Army in wheeled armored vehicles and pickup trucks, galloping over the vast distance. At the same time, at the end of the horizon of the grassland, the Angolan tribal army supported by the Soviet Union is ready, and the encounter is imminent
