Take Off My Aviation Era

Pan Xu didn't know much at first, but when he got there, the more he listened, the brighter his eyes became. In the end, he couldn't help holding Kong Qingfeng's hand and his big fat face smiled brighter than Chrysanthemum: "Old Kong, really works? Customers who provide mortgages or part of the down payment can you give them loans to buy our equipment?"

It’s no wonder that Pan Xu would be like this. He knew that the bank had loaned companies to expand production, and it was the first time he heard that he could loan customers to buy corporate products.

This is tantamount to expanding the customer base. You must know that not all customers are financial fathers with sufficient funds. There are not a few shy people in the pocket. In the past, customers in the gardens and factories wanted to sell, but now there are banks. , Yuanli factory can do business with such clients.

In addition, this model is also very beneficial to the company’s accounting period. It is necessary to know that the most difficult to avoid corporate transactions is the accounting period. It is better to drag a few ten days and a half months, a long year and a half. Not new.

This has created a huge pressure on the return of corporate funds, and the company's own anti-risk ability is very fragile. Once there is a turmoil, it is easy to collapse.

With financial services as support, it is different. The customer's repayment risk is all passed on to the bank, and the enterprise can get full payment in a short period of time. Not only will the ability to withstand risks be enhanced, but there will also be room for continued expansion of reproduction.

It's so good, Pan Xu doesn't even think he is excited.

Kong Qingfeng’s attitude towards Pan Xu’s sudden change has not been the slightest surprise. He has seen many similar things on Hong Kong Island. He has long been no stranger to it. As long as the business can be achieved, all things are trivial. Kong Qingfeng wouldn’t frown even if he had a deal with the devil to a certain extent, so he nodded:

"The premise is that their assets are in good condition, have a high reputation, and have a long-term profit model. But you can rest assured that our bank will investigate in the past. We will not lend if they do not meet the requirements, such as the plateau eagle in Nepal. The project is a success.

Oh, yes, their power supply is very underdeveloped. If Director Pan is interested, you can try it. If you can, our procedures will be simplified a lot. After all, we have just completed the survey in Nepal. Of course, this Mr. Dezhuang agreed, after all, our bank’s benchmarking pilot is only the Ascendas Aviation Manufacturing Corporation. "

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

Let the gas turbine power unit of Ascendas Aviation Manufacturing Corporation go abroad, expand overseas markets, and gradually improve the experience and reliability of its use. This is the way to develop gas turbine power units. Otherwise, Zhuang Jianye will have to do so many things a day. Give Pan Xu and Kong Qingfeng a relationship.

The main reason is that the gas turbine power plant of the Aviation Power Plant under the Ascendas Aviation Manufacturing Corporation has reached a critical stage, especially the hy-4-1 core machine developed by the resources of the entire head office. Although several prototypes have been built, there are also tests. A good result.

However, the d-30 and d-40 turboprop engines developed based on them are still far from the Honeywell tpe331 series turboprop engines currently installed on the Plateau Eagle by Ascendas Aviation Manufacturing Corporation.

Mainly focus on the three aspects of short overhaul interval, service life, and low reliability.

The average overhaul interval of Honeywell tpe331 series turboprop engines is 3,600 hours, while the d-30ml of the non-reconnaissance-8a "PLAS" UAV equipped in the Air Force Surveying and Mapping Brigade is only 1,800 hours, only for the tpe331 series turbines. Half of the propeller engine.

That's all, the key is that the service life of Ascendas d series is not as good as Honeywell's tpe331 series. It is important to know that the full life of the tpe331 series exceeds 10,000 hours, and the best performance among Ascendas d-30 is only 7,000. Early hours.

If you encounter a guy who likes violent output, even if you have 5,000 hours of luck, the tpe331 series can still maintain a lifespan of 10,000 hours.

It's just that these two points are not critical. What makes Zhuang Jianye unacceptable is that the reliability of Ascendas power is somewhat unsatisfactory. This is mainly concentrated in two aspects: one is the turbine blade; the other is the lubrication system of the engine.

Needless to say, the turbine blades are not only a problem with the power of Ascendas, but it is similar to the whole country and the whole world. Fortunately, Ascendas Aviation Manufacturing Corporation took precautions in the early years and launched the electrochemical perforation device. Now it is progressing very smoothly. Once a breakthrough is made, the turbine blades of Ascendas Power will be upgraded from the current ordinary nickel-based alloy to the second-generation turbine blade with a composite cooling system.

At that time, the temperature in front of the turbine of the hy-4-1 core engine will increase from the current 654 degrees Celsius to 856 degrees Celsius. The 200 degrees Celsius increase in temperature will bring a power jump. By then, the hy-4-1 core engine will be used. Based on this, gas turbine power plants with a power of more than one kilowatt are not a problem.

So this problem is not anxious to take off the power up and down, but the lubrication system of the engine makes up and down headaches, because no one expected such a serious hidden danger in this place.

How serious is it? It is possible to park in the air if the engine fails.

The main reason for this problem is that the existing processing methods of Ascendas Power are too low to allow the compressor and turbine on the engine rotor to be placed on the supporting bearings with light weight. Only double bearings or even four bearing structures can be used to maintain Stable operation of the rotor and its accessories.

But in this way, not only the weight of the engine has increased, but the lubrication system has also become very complicated, and reliability is difficult to guarantee. Once a problem occurs, the bearings inside the engine will soon be overwhelmed, causing deformation and friction micro-welding. As a result, the strength of the bearing is reduced. Over time, the local deformation will increase the frictional resistance~www.readwn.com~, eventually leading to the loss of rotation accuracy of the bearing, jamming of the shaft, and subsequent engine shutdown.

It is for this reason that the overhaul time and service life of the d series of Ascendas Power will be greatly reduced, and the economic efficiency is not even a little bit worse than that of the tpe331 series.

This makes Zhuang Jianye very dissatisfied, but continuous improvement in the laboratory is not a solution. This can easily lead to a life-and-death like working behind closed doors, and it is not economical. It is still necessary to push to the market and use customer feedback to supervise and force it A little bit of power, the hy-4-1 core engine is perfected, and the d series gas turbine power plant is completed.

You must know that Honeywell's tpe331 series did not sway everything as it is now. It has not been a little improvement from the 1950s. A little improvement has achieved today's achievements. The key is to focus on the market. Use more and turn to gain experience.

Just like a game, how can you gain crazy experience if you don’t play wildly? Novice Village is in Niu, that is also a rookie.

Today’s take-off power is such a rookie who just came out of the novice village. If you want to gain experience, you have to boldly go out. After all, there is no shortcut to the aviation engine. In addition to the massive amount of funds, the profound experience is indispensable. .
