Hearing this discordant voice, even the chief designer of BMW Singh frowned, because the person who spoke was his subordinate, Dr. Herman of the first engine department. Dr. Hermann is a very young man, only thirty years old, and he is already the backbone of BMW's engine design, and it is not an exaggeration to say that he is a genius. However, geniuses are generally arrogant guys, like this Herman, who usually doesn't even pay attention to Singh, the chief designer, let alone Philip.

Philip looked at the person who was talking, and saw the name of this person from the sign in front of him, which turned out to be Hermann Osrizi, a very famous aero-engine designer later. This person later presided over the design of the BMW 003 axial jet engine, which can be regarded as the originator of the practical jet engine.

Philip was not angry, and said with a smile: "This is Dr. Herman!" If you can ask such questions, you are genuinely interested in this engine project. So I'm more than happy to answer that question for you. Jet engines are indeed very complex aeropower plants, but our design team has completed a full set of design drawings and we have sufficient development funds to ensure that you don't have to worry at all. As the engineers at BFW know, we have a scaled-to-size jet engine right in the BFW R&D center, so if Dr. Herman is interested, they can check it out. This scaled-down jet engine is much simpler than the actual product, but it gives you an idea of the main structure of a jet engine and how it works. ”

Herman was surprised: "Oh? And there is such a thing. Why don't you bring this thing here and open the eyes of our BMW engineers, so that we can have more confidence. ”

Herman thought to himself, this Philip is afraid that he is not fooling, how can there be such a small jet engine, it is simply unheard of, if this is the case, he will be convinced.

You must know that Herman is also a very conceited designer. In BMW, he considers himself the first person below Dr. Singh, and in terms of engine design ability and knowledge, he even thinks that he will not be worse than Dr. Singh, what he lacks is just qualifications, and he believes that he will definitely become the chief designer of BMW in the future, and become one of the best engine designers in the world. Therefore, he did not believe in the downsized jet engine that Philip was talking about.

Philip also said secretly, this person is really troublesome, now it is the engine trial production coordination meeting, and the time is also very urgent, but I didn't expect this Herman to give him this problem, it seems that this Herman is not convinced, this engine trial production coordination meeting is really not good.

So Philip laughed and said, "Good! If I don't agree, I'm afraid that Mr. Herman will think I'm talking nonsense, so let's show you what a jet engine looks like, so that you can have a number in the process of trial production. ”

With that, Philip turned his head to look at Messerschmidt and said, "Dr. Wiley, please arrange for two people to bring over the miniature jet engine, as well as the test bench and oil pump and other accessories, and run it here for a few minutes, so that the BMW engineers can see what is going on." ”

Messerschmitz nodded and said, "Okay, I'll arrange that." Tony, Noah, you two go and bring that miniature jet engine, and we'll show the BMW engineers here. ”

The two young engineers answered, turned and strode out of the conference room to move the engine.

Dr. Singer, who was next to him, asked curiously, "Mr. Philip, how come I have never heard of a miniature jet engine?" ”

Philip said with a smile: "The miniature turbojet engine, it includes the main structure of large jet engines such as housing, bearings, rotating shafts, intake outer stator, intake stator, shaft sleeve, tail exhaust stator, fairing, tail shaft nut, exhaust stator, exhaust impeller, control device, etc., turbojet engine contains four sections: compressor, combustion chamber, turbine joint, and exhaust joint. The compressor part of the air passes through the intake tract at high speed to the combustion chamber. The combustion chamber contains a fuel inlet and an igniter for combustion. The expanding air drives the turbine, which is connected to the compressor by a shaft, supporting the operation of the engine. Thrust is provided by the exhaust from the exhaust of accelerated exhaust. This is the basic application of compressed air, igniting the air-oil mixture, generating power to self-sustain the engine, and exhaust gas for propulsion. The principle is actually not complicated. ”

As soon as the words fell, Tony and Noah walked to the rostrum carrying the miniature jet engine mounted on the test bench, and the oil circuit had been connected.

The BMW engineers were all curious at this strange device, they didn't understand what it was, what the parts were for, they couldn't understand it at all, and they couldn't be blamed for it, because none of them had ever seen what a jet engine looked like, let alone what the structure looked like.

Herman didn't expect them to actually bring out such a guy, and it looked like the cup attached to the shelf was a miniature jet engine. After all, he still knew about jet engines, and of course the miniature jet engine he saw was very different from the jet engine that he had learned Whittle had designed on paper.

Philip laughed: "Mr. Herman, this is our microjet engine, although it is only the size of a cup, it can produce several kilograms of thrust, let the engineers of BFW show you how this microjet engine works." Mr. Noah, Mr. Tony, just ask the two of you to do it. ”

Noah and Tony had also seen Philip build the microjet himself, and BFW's engineers had tried to run the minijet many times, so they were familiar with it.

Under the watchful eye of BMW engineers, Noah and Tony quickly set the jet on fire, and when an orange flame flashed out of the tail nozzle, the miniature jet began its twentieth operation.

The miniature jet engine let out a powerful roar, and then whirred, the hot air at the tail even ejected far away, and the test bench weighing dozens of kilograms was also shaking constantly, as if it could not withstand the strong thrust and wanted to break through the air.

BMW's engineers were dumbfounded, and even Herman, who had always been very conceited, had to admit that the miniature jet engine had been designed so successfully that he now fully believed what Philip had said, and that building a jet engine that could fit into an airplane was no longer an unattainable dream.
