Sun Xiaoping and Qiu Wenan, who were seated, also glanced at each other, and the two knew in their hearts that the engine that was about to be developed was definitely not a high-power diesel engine, but a turboshaft engine.

Replacing high-power diesel engines with turboshaft engines is a very advanced concept, and many countries are carrying out research in this area, and high-power diesel engines are definitely backward in the face of turboshaft engines.

Sure enough, Li Tianfeng smiled and said: "Mr. Xu, we don't want to develop a high-power diesel engine, what we need to develop is a turboshaft engine." ”

Xu Lilong was puzzled for a while and asked: "Boss, as far as I know, the engines of well-known tanks in various countries around the world are basically high-power diesel engines. ”

Li Tianfeng said: "Not necessarily, most of the world's well-known tanks, their engines are basically high-power diesel engines, but there are also those that do not use diesel engines, such as the American M1A2 main battle tank, whose engine is a turboshaft engine." ”

"The Americans have undoubtedly come to the forefront, and I think that in the future, turboshaft engines will completely replace and phase out high-power diesel engines."

Sun Xiaoping said: "Boss, I completely agree with your point of view, the high-power diesel engine is not only bulky, but also a big oil tiger, which greatly restricts the maximum stroke of the tank." ”

Qiu Wenan also said: "Water-cooled diesel engine, 1500 horsepower power has reached the extreme, and if the power is increased further, the weight and volume of the engine will be greatly increased, and it is impossible for a tank to fit such a big bulky guy." ”

Li Tianfeng said: "Yes, the turboshaft engine will not be like this, even if the weight of the 2,000-horsepower engine is much lighter than the water-cooled diesel engine, the volume is much smaller, and the fuel consumption per 100 kilometers will not be higher than that of the water-cooled diesel engine." ”

Looked at. Xu Lilong understood that it was not a water-cooled diesel engine that was developed, but a turboshaft engine.

Li Tianfeng said: "The engine we are going to develop, I will decide now, it is not a water-cooled diesel engine, but a turboshaft engine. With our turboshaft E engine as the core engine, on this basis, we have developed a turboshaft engine with low fuel consumption, high life, high reliability and good maintainability, which creates an excellent power for our Type 99 tank. ”

Li Tianfeng set the tone in this way, and then Li Tianfeng put forward a series of requirements for this engine to be developed. Especially the technical requirements.

Finally, Li Tianfeng said: "Mr. Sun, Mr. Qiu, this engine, you two are the chief designers of the model, and you will send me the design plan for you to see." ”

This time, Li Tianfeng decided not to draw up the design outline, but handed over the task to Sun Xiaoping and Qiu Wenan. This is for the purpose of exercising everyone.

In addition, Li Tianfeng also knows. Sun Xiaoping and Qiu Wenan will definitely be able to do such a thing, because they have a ready-made core machine, and they have rich design experience, so they can let the two of them do it.

The amount of work to develop such an engine is not very large. Even Mr. Wei knew that this was an appetizing, and Li Tianfeng knew this even more, and he was completely assured that the two of them would carry out the design, and there was no need to do it himself.

Sun Xiaoping and Qiu Wenan stood up together. Langsheng said that he promised to complete the task, which can be regarded as taking over the research and development task.

Li Tianfeng is willing to develop such a tank power, which is a good start, indicating that Tianfeng Technology's products have begun to derive, no longer limited to aero engines.

In fact, from aero engines, many engines can be derived, such as missile or rocket engines, tank or armored vehicle engines, and gas turbines for various warships.

All of these engines can be developed on the basis of aero engines, and the power of this Type 99 tank is the same, which will be based on the turboshaft E engine to develop a 2000 horsepower turboshaft engine for tanks.

After the meeting.

Li Tianfeng, who returned to the office, also thought seriously for a long time, for this turboshaft engine, Li Tianfeng naturally had a preliminary plan in his heart, but Li Tianfeng would not say it now, but asked Sun Xiaoping and Qiu Wenan to design it first.

After thinking about it, Li Tianfeng said in his heart, the technical difficulty is not great, with the technical strength of the design team of Tianfeng Technology Company, coupled with his own final check, it can really only be regarded as an appetizer.

Canada, Bombardier Inc.

In the huge aircraft assembly plant, several aircraft are being assembled, and two engines are next to the aircraft and are about to be loaded on this aircraft.

These two engines are the turbofan 17 engines of Tianfeng Technology Company, and the aircraft next to it is a 70 to 100-seat regional airliner.

The engine compartment of the aircraft has been opened, and several Bombardier technicians are lifting one of the engines in preparation for lifting.

The engine slowly left the ground, hoisted into the engine compartment, slowly aligned the installation hole and installation datum, a worker in work clothes, climbed up with tools, installed the installation screws one by one, and then used testing tools to detect whether the installation meets the technical requirements.

Peng Jiangtao was wearing Tianfeng Technology's work clothes, which was very conspicuous, in stark contrast to the technicians next to him who were wearing Bombardier's work clothes.

Now Peng Jiangtao is already the technical director of the Canadian office of Tianfeng Technology Company, and it is a common thing to come to this assembly plant to take a look.

Every time he came over, many Bombardier technicians or workers would give Peng Jiangtao a thumbs up, and Peng Jiangtao knew that this was someone praising his engine.

Turbofan 17 engines, dozens of units have already been installed, and more than a dozen aircraft have been installed with such engines to leave the factory and deliver to users.

Peng Jiangtao saw that two more turbofan 17 engines were installed on the plane, and in his mind, he couldn't help but think of the test flight of the turbofan 18 engine.

The two turbofan 18 engines provided by Tianfeng Technology to Bombardier successfully completed their first flight half a month ago, and now, in a series of verification test flights, Peng Jiangtao has been paying attention to and tracking the test flights of these two engines, and until now, the test flight performance is very good.

Next to Peng Jiangtao, a blonde foreigner of the same age as Peng Jiangtao and relatively young, is obviously a Bombardier technician.

The blonde foreigner said, "Peng, your engine is very good, not the slightest worse than the models of engines we purchased before. ”

Another foreigner said: "I think it's better than those engines." ”

Peng Jiangtao smiled happily, and then everyone walked to the plane, which was installing the engine, and the installation speed was relatively fast.

It didn't take long for the first engine to be installed, and a worker, on the open engine compartment, had already begun wiring the engine.

The second engine began to be hoisted again, and soon it was hoisted into the engine compartment and the assembly began, which seemed to be very smooth.

The blonde foreigner said: "Peng, your turbofan 17 engine is really good, the design is very comprehensive, even the installation and operability of the engine have been considered, the engine is very easy to install, and the installation of the engine can be completed with general tools, which is great." ”

On the basis of the turbofan 17 engine, the regional airliner that needs to install the turbofan 17 engine needs to be installed, Bombardier has made certain changes to the engine installation compartment, and improved it according to the assembly requirements of the turbofan 17 engine.

After this improvement, Bombardier immediately saw the benefits, that is, the installation of the engine was greatly reduced, it was extremely easy to operate, and the installation of the engine was much faster.

Peng Jiangtao knows that at the beginning of the design of the engine, the maintainability was fully considered, even under the field conditions, skilled workers can use ordinary general tools to repair the engine, including the installation and disassembly of the engine.

In the engine compartment, a Bombardier worker who was installing the engine saw Peng Jiangtao and gave Peng Jiangtao a swaying thumbs up.

Tianfeng Technology Company.

Li Tianfeng was receiving Ma Delong and his entourage, and with the popularity of the ARJ21 regional airliner and the C919 airliner, COMAC needed a large number of engines.

At present, the orders for ARJ21 regional airliners have reached more than 600 aircraft, and the orders for C919 airliners have also reached 450.

In the past, these two planes were all imported engines, and when everyone talked about these two aircraft, the waist rod of the Maderon has never been as straight as it is today, because it was a foreign core before, not a domestic engine.

Now, the waist of the Maderon is straight and strong, and these two aircraft are now all real domestic engines, and they are still very good domestic engines.

in the reception room.

Li Tianfeng and Ma Delong were drinking tea and chatting, as for the rest of Ma Delong's entourage, under the leadership of Liu Wei, everyone went to visit the processing site of Tianfeng Technology Company with great interest.

Li Tianfeng said: "Mr. Ma, I heard that you are negotiating with a foreign user, and the other party has shown strong interest in your ARJ21 regional airliner and C919 trunk airliner. ”

Ma Delong said happily: "Basically, the negotiation is almost over, and our two aircraft will also go abroad and begin to enter the international market." ”

Li Tianfeng said happily: "Mr. Ma, congratulations. ”

Ma Delong said: "Mr. Li, be polite, happy and happy, in this way, we need more engines from you." ”
