Seeing that the BMW engineers were shocked, Philip also smiled proudly. These Germans are like that, not only are they very strict in their work, but they also have their own pride, and they will only work for you if they are really convinced. If these proud BMW engineers are not suppressed, they will definitely process parts for the Dragon Soul Ordnance Consortium as required, because after all, this is a profitable business, but these people will definitely look down on the Dragon Soul Ordnance Group and think that this is nothing more than a failed research and development.

Now BMW engineers look at Philip differently, it is a look with reverence, how can they not be respectful to the strong? Dr. Herman, in particular, thought that he was already a top expert in the field of engines, but after seeing the demonstration of this miniature jet engine, Herman knew that Philip's attainments in the field of engine expertise were far higher than his. Therefore, he had to put away his arrogant attitude.

Philip exclaimed, "Okay, you've all seen what the jet engine is, so I'll talk about the trial production of parts." Because BMW has a strong strength in engine design and manufacturing, and has an unusual relationship with BFW, we entrust most of the parts processing to BMW. However, after all, the jet engine is a new type of engine, a product that has not been successfully developed by any company, and we are also crossing the river by feeling the stones, and we don't know what problems will be encountered in the trial production process of parts. The processing of jet engine parts and piston engine parts is also different, because their large parts are in an extremely harsh working environment, especially high temperature and high speed and high speed, and the accuracy of parts processing and some heat treatment process requirements are very high, otherwise unqualified parts will have very serious consequences once they are used on the jet engine. ”

Herman stood up and said loudly, "Mr. Philip, please rest assured! At BMW, we are known for our professionalism and rigour, and we will process it according to the requirements. I wonder what is the difference between the machining process of jet engine parts and the machining of piston engine parts? ”

Philip laughed, "Dr. Herman asked a very good question, so I'll start with the structure of the jet engine." The main structure of the jet engine includes a compressor, a combustion chamber, a gas turbine, a power turbine and an exhaust device, as well as accessories and supporting structures, among which the compressor combustion chamber and the turbine, these three components are collectively called the gas generator, because they are in the core of the engine, so they can be called the core engine. In the development of jet engines, the most critical is the development of the core engine, with a good core engine plus various other components, you can get different types of engines, such as turboprop engines, turboshaft engines can be derived from this core engine. For example, there are many methods for compressor casing processing, such as casting, forging and sheet metal welding, and these processing methods also have their own advantages and disadvantages, which need to be considered comprehensively. ”

After a pause, Philip continued: "For example, the casting casing, this way has good process characteristics, the reinforcing ribs, venting holes and other structures can be cast at one time, the amount of machining is small, it can only be applied to the light alloy casing, if the wall thickness of the casting casing is too thin, it is more difficult to cast, it is not easy to cast, if it is too thick, the cooling time will be extended, the casting structure will deteriorate, and the material strength limit will be reduced." Therefore, the wall thickness of the light alloy casing can only be taken 6 to 10 mm, and it can only be used in places where the temperature is lower than 200 degrees, and it cannot be used if the pressurization is relatively high. Let's talk about the forging casing, it is the use of a relatively thick blank, usually about 40 mm, after machining, the casing before and after the processing of the installation edge, the inner surface of the casing to make a variety of grooves, used to install rectifier blades, the outer surface of the casing milled out of various grooves, protrusions, mounts and venting holes, etc., but this processing method has a large amount of machining, low utilization rate of blanks, poor manufacturability, and high cost. The sheet material casing is made of two or three millimeters thick steel plate rolled into a cylinder, welded with the installation edge and profile ring made by turning and milling, these processing techniques have their own applicable places, and need to be selected by comprehensively considering various factors such as cost and structural design. Therefore, the processing of jet engine parts is a very complex work, and there can be no sloppiness, and it is necessary to choose the appropriate processing technology after comprehensive consideration. ”

Herman stood up again and said excitedly, "Mr. Philip, please forgive me for the offense just now, I did not expect the jet engine to be so complex and extremely challenging. But the more challenging, the more our BMW engineers like it, and we guarantee that all the parts will be machined according to the requirements, so please trust our strength. ”

Philip nodded and said, "Dr. Herman, please be seated." I fully believe in your strength, otherwise I will not cooperate with you, you must know that the future potential of jet engines is unlimited, so our wind and thunder jet engine design is a highly confidential document, I hope you do not leak the process parameters in it, otherwise this involves the issue of breach of contract, we will write in the contract. Please keep in mind that if the leakage of confidential information leads to serious consequences, you will be liable for a large amount of liquidated damages. Of course, it will also be of great benefit to you to undertake this contract of contract processing, and perhaps in the future, you can also develop jet engines through the jet engine design and processing technology obtained in the process of contract processing, and maybe then we will have a competitive relationship. Of course, we have great confidence in our designs and are not afraid of any company challenging ourselves in the jet engine space. Hahaha! ”

Dr. Singh continued: "Mr. Philip, you can rest assured that although our BMW company is mainly engaged in engines, we will still be based on piston engines and at the same time devote ourselves to the development of automotive products, and it is impossible to get involved in the development of jet engines for the time being. Of course, we are more than happy to undertake the mass production of your engine parts. ”

Philip nodded and said, "Of course we do." At present, jet engines have not received the attention of various countries, but when we develop them, this situation will definitely change, and the performance advantages of jet engines will soon be reflected. Of course, it is unlikely that it will completely replace the piston engine, but at least in the field of military aircraft it has much better prospects than a piston engine. ”
