Chapter 461 The Development of Gas Turbine Power Plants

    Pan Xu didn't do anything at first, but later on, the more he listened, the more his eyes lit up. In the end, he couldn't help but hold Kong Qingfeng's hand and his fat face smiled brighter than a chrysanthemum: "Old Kong, is it really possible? As long as foreigners  If our customers provide a mortgage or part of the down payment, can you provide them with a loan to purchase our equipment?¡±

    No wonder Pan Xu is like this. He knows that banks provide loans to companies to expand production, and this is the first time he heard that he can provide loans to customers to purchase company products.

    This is tantamount to expanding the customer base. You must know that not all customers are wealthy donors, and there are many who are cash-strapped. In the past, such customers had to weigh and weigh even if they wanted to sell, but now banks have taken care of it.  , Yuanli Factory can do business with such customers in a bright and clear way.

    In addition, this model is also very beneficial to the company's account period. You must know that the most difficult thing to avoid in a company's transactions is the account period. It is better to drag it out for a few ten days and a half, or as long as a year and a half.  Nothing new.

    This has caused huge pressure on companies to withdraw funds, and the company's own ability to resist risks is very fragile. Once there is a disturbance, it can easily collapse.

    With the support of financial services, it is different. The customer's repayment risk is all transferred to the bank, and the company can get full payment in the short term. Not only does it increase its ability to withstand risks, but it also has the ability to continue to expand reproduction.

    With such good news, Pan Xu couldn¡¯t even think about being excited.

    Kong Qingfeng was not surprised at all by Pan Xu's sudden change of attitude. He had seen many similar things on Hong Kong Island and had long been used to it. As long as he could close a business, being arrogant or disrespectful was nothing. If the profit was  When the situation reached a certain level, even if he made a deal with the devil, Kong Qingfeng would not frown, so he nodded:

    "The premise is that their assets are in good condition, have high credibility, and have a long-term profit model. But you can rest assured that our bank will investigate in the past. We will not lend to those who do not meet the regulations, such as Nepal's Plateau Eagle.  A project is a success.

    Oh, by the way, the power supply there is very underdeveloped. If Director Pan is interested, you can give it a try. If possible, our procedures will be simplified a lot. After all, we have just completed the survey in Nepal. Of course, this  Mr. Zhuang agreed. After all, the only benchmarking pilot company for our bank is Tengfei Aviation Manufacturing Corporation.  "

    "There is no problem with me. The core equipment used in the factory in the park is originally produced by us, and it can be affiliated with us." Zhuang Jianye nodded without hesitation.

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

    The main reason is that the gas turbine power plant of the aviation power plant affiliated to Tengfei Aviation Manufacturing Corporation has reached a critical stage, especially the hy-4-1 core aircraft developed by pooling the resources of the entire corporation. Although several prototypes have been built, there are also some tests.  A good effect.

    However, there is still a certain gap between the D-30 and D-40 turboprop engines developed based on them and the Honeywell TPE331 series turboprop engines currently installed on the Plateau Eagle by Ascendas Aviation Manufacturing Corporation.

    Mainly focused on three aspects: short overhaul interval, service life, and low reliability.

    The average overhaul interval for Honeywell's TPE331 series turboprop engines is 3,600 hours, while the D-30ML of the Wuji-8a "Plass" UAV equipped with the Air Force Surveying and Mapping Group is just 1,800 hours, which is only 1,800 hours for the TPE331 series turbines.  Half of a propeller engine.

    That¡¯s it. The key is that the service life of Tengfei Power¡¯s D series is not as good as Honeywell¡¯s TPE331 series. You must know that the TPE331 series has a full life span of more than 10,000 hours, while the best-performing D-30 in Tengfei Power is only seven thousand hours.  Make a difference when you are young.

    If you meet someone who likes violent output, you will be lucky to have 5,000 hours, but the tpe331 series can still maintain a lifespan of 10,000 hours.

    " It's just that these two points are not critical. What is most difficult for Zhuang Jianye to accept is that the reliability of Tengfei Power is somewhat unsatisfactory. This is mainly concentrated in two aspects: one is the turbine blades; the other is the engine's lubrication system.

    Not to mention the turbine blades, it is not just the Ascendas Dynamics that has problems. It is similar across the country and even the world. Fortunately, Ascendas Aviation Manufacturing Corporation took precautions in the early years and launched an electrochemical drilling device. Now the progress is very smooth.  Once a breakthrough is achieved, Tengfei Power's turbine blades will immediately be upgraded from the current ordinary nickel-based alloy to the second generation turbine blades with a composite cooling system.

    By then, the temperature in front of the turbine of the hy-4-1 core machine will increase from the current 654 degrees Celsius to 856 degrees Celsius, a temperature increase of 200 degrees Celsius.This will bring about a leap in power. By then, gas turbine power devices based on the hy-4-1 core machine with a power of more than 1,000 kilowatts will not be a problem.

    Therefore, Tengfei Power is not worried about this problem. On the contrary, it is the engine lubrication system that gives them a terrible headache, because no one expected that such a serious hidden danger would appear in this place.

    How serious is it?  If the engine is not properly fixed, it may stop mid-air.

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

    But as a result, not only does the weight of the engine increase, but the lubrication system also becomes very complex, making it difficult to guarantee reliability. Once a problem occurs, the bearings inside the engine will soon be overwhelmed, causing deformation and friction microwelding.  This will reduce the strength of the bearing. Over time, the local deformation will increase the friction resistance, eventually causing the bearing to lose rotation accuracy and the shaft to become stuck, followed by engine shutdown.

    It is for this reason that the overhaul time and service life of Tengfei Power's d series will be greatly reduced, and the economy is not even a little worse than the tpe331 series.

    This makes Zhuang Jianye very dissatisfied, but continuing to improve in the laboratory is not the answer. This can easily lead to a life-and-death situation behind closed doors, and it is also uneconomical. We still have to push it to the market and use customer feedback to urge us to take off.  The power will gradually improve the hy-4-1 core engine and complete the d series gas turbine power device.

    You must know that Honeywell's TPE331 series was not as aggressive as it is now. It was not just a little bit of improvement and perfection in the 1950s that led to today's achievements. The key is to pay attention to the market. Only  Use it more and spin more to gain experience.

    It¡¯s just like a game. If you don¡¯t play wildly in the wild, how can you gain experience like crazy?  If there is a cow in Novice Village, he 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 go out boldly. After all, there is no shortcut when it comes to aviation engines. In addition to massive funds, you also need deep experience, both of which are indispensable.  .
