- Faced with this situation, Zhuang Jianye really had nothing to say.
It cannot be said that domestic aero-engine development units and production plants are not working hard and enterprising, but the mentality of greed for bigness and seeking perfection abounds.
Generally speaking, this is not wrong. After all, it is human nature to pursue higher, faster, and stronger. What's more, high-thrust aeroengines are the crystallization of all human industrial wisdom. With them, the performance of fighter jets can be even better. It is excellent. With it, large transport aircraft and bombers can soar into the sky, and with it, large civil aviation aircraft can fly across the ocean.
Of course, if you can complete it, the participating technical staff will receive higher honors, and the leading officials will be promoted faster.
What can a small turbine gas power plant under 1,000 kilowatts do? Even if the superior leaders came to inspect, they would be embarrassed to show it off. It is so small and the power is so low. If the leader asked, what kind of aircraft can this thing of yours fit in, it would be embarrassing to talk about it.
In addition, foreign countries¡¯ open attitude towards turbine gas power used in aircraft auxiliary power units has also prompted domestic units to become casual about this field.
Especially with the introduction of a new batch of large wide-body passenger aircraft such as Boeing and McDonnell Douglas, supporting aircraft auxiliary power units have also entered the country in the form of spare parts.
For example, the Model-36 aircraft auxiliary power unit on the six Boeing-737 passenger aircraft just imported by Civil Aviation has been favored by the Northwest Institute because of its stable performance and superb high-altitude starting capability, and it has been applied in the improved version of the Yun-7. on, becoming the auxiliary power system of the latest Yun 7.
As for fighter jets, 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 all are mechanical instruments, and there are no requirements for the airborne power system. outstanding, so the auxiliary power only stops at starting the main engine.
Therefore, they are generally made very small, with a maximum weight of only fifteen kilograms. Coupled with material and structural limitations, the power is not very high.
Therefore, domestic fighter aircraft are often equipped with ground support equipment such as power supply or gas supply at the airport. The reason is that the J-6 and J-7 fighters do not have independent power supply and gas supply auxiliary power units, which also indirectly increases the ground support equipment. burden.
But because of the different combat concepts and tactical composition, the troops did not seem to care about this. It was not until the emergence of the J-20 in the 2010s that this idea was completely changed, and an APU aircraft auxiliary power unit was installed inside the fuselage.
The reason for this is very simple. The auxiliary power unit APU is a set of small engines installed on the aircraft that do not rely on any energy outside the aircraft and are self-contained.
When the aircraft is being maintained on the ground and the main engine is not working, the APU can provide electrical, pneumatic, hydraulic and other energy to the aircraft. It does not rely on the support of ground equipment, improves the aircraft's self-sufficiency and maintenance support, extends the service life of the main engine and reduces the cost of the aircraft. life cycle maintenance costs.
When the engine fails in the air, or when the power supply or hydraulic system fails, the APU can provide auxiliary energy such as power supply and hydraulic pressure, and can assist the engine in quickly starting in the air, improving the safety and flight capabilities of the aircraft.
But this is all a thing for another day. Today, the domestic aviation industry, especially the military, has not paid enough attention to this aspect.
Therefore, the t-62t that Zhuang Jianye worked so hard to achieve was completely useless. It was because his grandfather did not care for his uncle. Of course, if Liszt could follow Zhuang Jianye¡¯s idea and get the model-36, the effect would probably be better. After all, This auxiliary power unit is used on Boeing and McDonnell Douglas passenger aircraft in civil aviation, and it can get some credit.
"However, the effect will not be too great. After all, the newly arrived wide-body passenger aircraft of civil aviation have their own maintenance support system. Tengfei Factory has learned how to do it in the past. If you start to take the job, you will probably be beaten with a stick.
All in all, in short, the introduction of APU this time is a losing business no matter how you look at it.
"Director Zhuang Xiaozhuang"
Just when Zhuang Jianye was hesitant about the turbine gas power plant, the bursts of voices on the phone finally brought Zhuang Jianye back to his senses: "Um Professor Qian, I'm sorry, I was a little distracted just now, you said "
Hearing Zhuang Jianye's reply, Qian Qiang finally breathed a sigh of relief. He was really afraid that Zhuang Jianye wouldn't be able to handle it alone. He would drop millions without even seeing a splash, and everyone would suffer if he dropped it. No.
Furthermore, turbine gas power is not something that can be effective in one or two years. If nothing else, just look at 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, except for the Soviet Union. In addition to the several jet engines that have been successfully imitated by providing drawings and a complete set of technical information, how many self-developed models have been successfully produced?
? This is true even for a country, let alone a company.So Qian Qiang frowned and hesitated for a moment, then made up his mind and said: "Xiaozhuang, if that doesn't work, let's stop the jet power research for a while. This thing is too demanding and requires too much investment. If this continues, I'm afraid the factory won't be able to sustain it."
Zhuang Jianye held the phone in one hand and rubbed his face vigorously with the other. He was also struggling in his heart. From the time Master Ju and the others started doing jet power experiments to now, Zhuang Jianye has invested more than ten million, and all he got was a pile of scrapped parts. Except for the child, there is nothing.
There is no such a way to lose money. Stopping seems to be a good choice. Not only does it save one troublesome thing, but it can also save millions of dollars a year.
But if it really stops, let alone the huge civilian passenger aircraft market in the future, the APU on the fighter jet will be a huge piece of cake; in addition, the EPU (ground power unit) derived from the APU will be used in the electric power, metallurgy, and chemical industries. It also has a very wide range of applications.
There is no need to go abroad to compete with giants for the market. Domestic development in the next few decades will be enough for Tengfei Factory to make a lot of money in this area.
As for the small turbojet engine and small turbofan engine that were born out of APU, they are the best power for high-performance drones, anti-ship missiles, and cruise missiles. If the technology is mature and amplified, it can become the main power source of trainer aircraft and even business jets. Power module.
This is a very clear technological development route, and it is also a broad road paved with gold. Should we save money now for immediate benefits; or should we continue to burn money in order to have a lot of money chasing us tomorrow
"Go ahead, add another two million to the funding, and raise the total cost this year to eight million. This will be the case for the first half of the year. I will notify the finance accountant to increase the payment amount for the second half of the year. But Professor Qian, I would like to add that, then It¡¯s reliability, whether we imitate the American T-62t or innovate based on it, the reliability can never be worse than theirs!¡±
Zhuang Jianye finally gritted his teeth and made his final decision. Qian Qiang and Yan Tiancheng on the other end of the phone couldn't help but breathed a sigh of relief for some reason. Qian Qiang immediately said: "Don't worry, Director Zhuang, we won't I will betray your trust."
"good!"
Zhuang Jianye nodded, and after chatting for a few more words, he put down the phone. After that, he felt as if he was empty, and leaned on the back of his chair. Since he was a loser, he had to lose it completely. He couldn't continue to spend a few more years without even a splash. Can't even be smashed out.
But the most important thing now is to make money. Damn it, why can¡¯t Lister buy more DRO drones? Not only are they consumables, they also have a good profit margin
¡¡
Lister, who is in New York, has the same idea. Unfortunately, not everyone in South Africa can see the value of the "Attacker" drone like South Africa, because they prefer that the "Attacker" be a missile. , rather than some drone that no one understands.
So Liszt can¡¯t wait to go to the battlefield in person, hoping that those guys who long for the ¡°attacker¡± to be missiles will open their eyes and see that drones are thousands of times sharper than the missiles they imagined.
"It's just that Lister in New York couldn't realize this wish, but Weisberg, who returned to South Africa from the United States and then re-entered Angola from South Africa, could do it with a raise of his hand.
Because at this moment, he was leading a battalion of the Angolan Alliance Army, driving 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 had also prepared Be prepared, the encounter is about to begin
