After returning to Munich, Philip and Messerschmidt discussed and prepared to immediately convene a coordination meeting for the development of jet engines to divide the work of the entire engine development.

The meeting was attended not only by BFW's engineering and technical personnel, but also by BMW's engineering and technical personnel, because it is impossible to develop jet engines by BFW alone, after all, BFW is mainly engaged in aircraft design, and BMW has rich experience in engine design and development, and most of the engines in Germany are currently produced by BMW.

In fact, both BFW and BMW were originally one company, but later separated for a number of reasons. BFW later focused on developing aircraft, while BMW focused on engines and automobiles. There are many parts and components for the development of jet engines that need to be outsourced to BMW, after all, only BMW has specialized engine parts processing equipment, although they are currently producing piston engines, and jet engine parts can also be processed.

The night before the meeting, Philip and Messerschmidt met and began to discuss a prototype of a jet engine in their office. Now the design drawings of the wind and thunder jet engine have basically been completed, after all, this is a relatively primary jet engine, not as high as the later generations of high-thrust jet engines, and Philip has completed the overall design of the entire engine, in the BFW company R & D center with the efforts of those designers, can complete the whole set of design drawings in such a short period of time, you must know that this set of design drawings has a total of hundreds.

After the completion of the design drawing, the trial production of the parts is carried out, and the important parts are tested to determine whether they meet the design requirements. Finally, when all the parts are processed, it is the work of sample assembly, and when the sample assembly is completed, it will enter the prototype testing stage.

In fact, most of the parts were outsourced to BMW this time.

Philip sat on the sofa and sighed: "I have gained a lot from this trip to Romania, and if we can get this order, then BFW will have to be busy." Although the sales performance of the M20 transport aircraft is good, it is a small aircraft after all, and it is relatively simple to produce. In terms of the current production capacity of BFW, there are indeed many deficiencies, such as engine production, and now we do not have a dedicated engine production workshop, which is a problem that needs to be considered. After all, we can't always outsource the main engine parts, so the establishment of this engine production department should also be on the agenda, and I propose to establish a separate engine division. What do you think, Dr. Wiley? ”

Messerschmitt thought for a moment and said, "Philip, you're right! Although BMW has a very deep history as a BFW company, it is now an independent company, and its main business is to produce piston engines and automobiles, and in the future, we must focus on the mass production of jet engines and turboprop engines, otherwise we will be controlled by others. I will personally plan this engine division, and strive to be established within three months, and it can be put into production within half a year, so that in the future, the main parts and final assembly of the Fenglei series engines will be completed by our own engine division. By the way, what are your plans for tomorrow's meeting? ”

Philip nodded and said, "Dr. Wiley, tomorrow's coordination meeting is very important. Now although we have completed the detailed design of the engine, but this is the first time we have developed an engine and it is a revolutionary and innovative jet engine, so there are many parts that may need to be modified, for example, when we design, there are many things that are not considered, when the parts are in trial production, it is possible that the materials, processing technology and other aspects are not adaptable, and it is even possible to modify the design repeatedly. In addition, when the parts are trial-produced, a test finds that its strength does not meet the requirements, what should I do? We had to change the design, or adjust the material formula, or even change to a new material. Therefore, in the process of trial production of parts, many things may be encountered, which requires close cooperation between our design team and processing units, so as to complete the trial production task of this parts in the shortest possible time. If we are not careful, the engine development process may be delayed for a long time, which will have an adverse impact on our wind and thunder plan, especially our M40 transport aircraft will face the situation that there is no suitable engine available. ”

Messerschmitt said with some concern: "Philip, what you say does make sense!" I'm just worried that the Storm Mine plan will be delayed. I also think that in the future, we can even install the wind and thunder turboprop engine on more aircraft, such as the Romanian commercial transport aircraft, such as the sports competition aircraft that we are about to build, if the turboprop engine is used, the overall performance of the aircraft should be improved a lot, right? ”

Philip said in a deep voice, "That's true. If you replace the piston engine with a turboprop engine, these aircraft will be completely transformed, and the jet engine can definitely break many records if it were used in sports competition aircraft. So tomorrow's coordination meeting is really important, you must know that the development of jet engines, in fact, most of the money and time are spent on trial production and testing. The characteristics of this new engine development are like this, the test is the catalyst for the development of jet engines, only through repeated tests, repeated modifications, repeated tests, in order to optimize the performance of the whole machine, enhance its reliability. ”

Messerschmidt asked curiously: "Philip, I really don't know much about engine development, especially jet engines. I would like to know, what tests does it probably need? ”

Philip sorted out his thoughts for a moment and said calmly: "Speaking of jet engine tests, maybe I can't finish talking about it for three days and three nights. Of course, due to the adoption of new materials and new processes, the test importance of jet engines is far greater than that of piston engines. For example, to design and manufacture a single-tube combustion chamber tester to complete the debugging of the flame cylinder, to use the blade grid wind tunnel blowing to test whether there is a problem in the design of the compressor, and the whole machine test bench is more important, it is the last level to test whether the engine meets the design requirements. ”
