Chapter 461

Pan Xu didn't know much at first, but when he got to the back, the more he listened, the more his eyes lit up. Finally, he couldn't help holding Kong Qingfeng's hand, and his big fat face was even more brilliant than the chrysanthemum: "old Kong, really OK? As long as foreign customers provide mortgage or partial down payment, you can give them loans to buy our equipment? "

It's no wonder that Pan Xu would be like this. Knowing that the bank loans to enterprises to expand production, he also heard for the first time that he could loan customers to buy enterprise products.

This is tantamount to expanding the customer base. You should know that not all customers are rich in money, and not a few of them are cash strapped. In the past, Yuanli factory had to weigh up even if it wanted to sell. Now, with the help of the bank, Yuanli factory can do business with such customers.

In addition, this model is also very beneficial to the accounting period of an enterprise. You should know that the accounting period is the most difficult thing to avoid in an enterprise's transaction. It's better to delay for several ten days and a half months, and it's not new for a long year and a half.

This has resulted in a huge pressure on the return of enterprise funds, and the enterprise's own anti risk ability is very fragile. Once there is a storm, it is easy to collapse.

It is different to have financial services as support. The repayment risk of customers is transferred to the bank, and the enterprise can get full payment in the short term. It not only enhances the ability to resist risks, but also has the spare power to continue to expand reproduction.

It's so good that Pan Xu can't be excited.

Kong Qingfeng is not surprised at Pan Xu's sudden change of attitude. He has seen many similar things on Hong Kong Island, and he has seen them for a long time. As long as he can get a business done, he has to be modest. If the profit is large enough, even if he makes a deal with the devil, Kong Qingfeng will not frown, so he nods: "the premise is their asset status Kuang lianghao, with high credibility, has a long-term profit model, but you can rest assured that our bank will investigate in the past and we will not lend money if it does not meet the requirements. For example, the highland Eagle project in Nepal is a success.

Oh, by the way, their power supply is very underdeveloped. If director Pan is interested, he can try it. If he can, our procedures will be simplified a lot. After all, we have just finished the investigation in Nepal. Of course, this needs the consent of general manager Zhuang. After all, our bank has only one benchmarking pilot company, Tengfei aviation manufacturing corporation. "

"I have no problem here. Originally, the core equipment used by the factory in the park was made by us, and it can be attached to us." Zhuang Jianye nodded without hesitation.

Let the gas turbine power plant of Tengfei Aviation Manufacturing Corporation go abroad, expand overseas markets, and gradually improve the use experience and reliability. This is the way to develop the gas turbine power plant. Otherwise, Zhuang Jianye will only give pan Xu and Kong Qingfeng a relationship when he has so many things to do in a day.

It is mainly the gas turbine power plant of the aviation power plant affiliated to Tengfei aviation manufacturing corporation that has reached a critical stage, especially the hy-4-1 core machine developed with the resources of the whole corporation. Although several prototype machines have been built, the test has also achieved good results.

However, there is still a gap between the D-30 and d-40 turboprop engines developed on this basis and the Honeywell tpe331 series turboprop engines currently installed on plateau Eagle by Tengfei aviation manufacturing corporation.

It mainly focuses on the short overhaul interval, service life and low reliability.

The average overhaul interval of Honeywell's tpe331 series turboprop engines is 3600 hours, while the d-30ml of the unmanned reconnaissance-8a "Plath" UAV equipped in the air force mapping brigade is just 1800 hours, only half of the tpe331 series turboprop engines.

That's all. The key is the service life. The D-series of take-off power is not as good as Honeywell's tpe331 series. You should know that the tpe331 series has a total service life of more than 10000 hours, and the best D-30 of take-off power is only 7000 hours.

If you meet a guy who likes violent output, it's lucky to have 5000 hours, but tpe331 series can still maintain 10000 hours of life.

But these two points are not the key. The most difficult thing for Zhuang Jianye to accept is that the reliability of Tengfei power is not satisfactory, which mainly focuses on two aspects: one is turbine blade; the other is engine lubrication system.

Needless to say, the turbine blade is not only a problem in Tengfei power, but also in the whole country and even the whole world. Fortunately, Tengfei Aviation Manufacturing Corporation launched the electrochemical drilling device in the early years, and now it is progressing very smoothly. Once a breakthrough is made, Tengfei power's turbine blade will be upgraded from the current ordinary nickel based alloy to a new one The second generation turbine blades of the combined cooling system.

At that time, the temperature in front of the turbine of hy-4-1 core machine will be increased from 654 ℃ to 856 ℃. The temperature increase of 200 ℃ will bring about a power leap. At that time, the gas turbine power plant based on hy-4-1 core machine with a power of more than 1000 kW will not be a problem.

Therefore, the problem of taking off power is not urgent. On the contrary, the lubrication system of the engine is a headache for the whole world, because no one expected that such a serious hidden danger would appear in this place.How serious is it? If one can't get the engine right, it's possible to stop in the air.

The main reason for this problem is that the existing processing methods of Tengfei power are too low to make the compressor and turbine on the engine rotor be placed on the supporting bearing lightly. The only way to maintain the stable operation of the rotor and its accessories is to adopt double bearing or even four bearing structure.

But in this way, not only the weight of the engine increases, but also the lubrication system becomes very complex, and the reliability is difficult to guarantee. Once there is a problem, the bearing inside the engine will soon be overburdened, and there will be deformation and friction micro welding, so as to reduce the strength of the bearing. After a long time, local deformation will increase the friction resistance, and eventually lead to the loss of rotation of the bearing Rotation accuracy, stuck shaft, followed by the engine stop.

It is for this reason that the overhaul time and service life of the D series of Tengfei power will be greatly reduced, and the economy is not as good as that of the tpe331 series.

This makes Zhuang Jianye very dissatisfied, but it's not the way to continue to improve in the laboratory. It's easy to lead to a closed door business, and it's not economical. We still have to push it to the market. With the feedback from customers, we can urge the take-off power to improve the hy-4-1 core engine and do a good job in the D series gas turbine power plant.

It is important to know that Honeywell's tpe331 series didn't do everything as it does now at the beginning. It wasn't just a little bit of improvement in the 1950s that led to today's achievements. The key is to pay attention to the market. Only by using more and transferring more can we gain experience.

It's just like a game. How can you have a long experience if you don't brush wildly? The rookie village is Niu, which is also a rookie.

Today's take-off power is such a rookie just out of the novice village. If you want to brush experience, you have to go out boldly. After all, there is no shortcut for aeroengine. In addition to huge amount of money, deep experience is indispensable.
