Chapter 1154 "Heart Disease" and "Enhancement"

Of course, there is still an important subsystem that has not been mentioned, that is, the research project about aviation development, and the specific point is about the development of aero-engines.The so-called aero engine is simply understood as the engine that provides the power required for flight by the aircraft.There are three main types, piston aero engine, gas turbine engine, and ramjet engine.In fact, Jiang Chen and the others really need these three types of engines. In fact, Jiang Chen and the others have been engaged in the development and application of one of the engines long before.

Not the first two, but the last ramjet.This type of engine is characterized by no compressor and gas turbine, and the air entering the combustion chamber is pressurized by the ram effect of high-speed flight.It has a simple structure and a large category of thrust aeroengines, and is especially suitable for high-speed and high-altitude flight.Due to the non-self-starting and poor performance at low speeds, the scope of application is limited to missiles and rockets, and air-launched targets.When Jiang Chen was in the B17 factory, he started the development of this engine as early as when he was engaged in the development of the 120mm rocket launcher.And after several years of development, especially in the research and development process of Chasing Wind and Shattering series missiles, great progress has been made, and it is currently proceeding in an orderly manner.

As for the piston aeroengine, it is an aeroengine used in airplanes or helicopters in the early days to drive propellers or rotors.The power of large piston aeroengines can reach 2500 kilowatts, but with the development of the times, it was later replaced by gas turbine engines with high power and high-speed performance. Instead, low-power piston aeroengines are still widely used in light aircraft, helicopters and ultralight aircraft.And Jiang Chen also understands that in the future, due to the relatively tight demand for energy, which will lead to rising oil prices, piston-type aero engines that consume less energy are still more popular in the civilian market, especially in foreign countries where the use of light and small aircraft is more developed. nation.Moreover, the structure of this type of piston aeroengine is relatively simple, safe and reliable, and the price is relatively cheap, which is very suitable for popularization in the civilian market.

Besides, this type of piston engine is actually an internal combustion engine, which uses the same principle as that used in automobiles, but the internal structure is different because of different requirements.From this point of view, Jiang Chen and the others are very advantageous in carrying out research on this type of piston aero-engine.After analyzing the overall pros and cons, Jiang Chen organized and coordinated some of these aviation experts and the engine (internal combustion engine) R&D laboratory to form a joint project team, specializing in the development of this type of piston aeroengine.After everyone's efforts, they have come up with an engineering prototype of a piston aero-engine used in light and small aircraft and helicopters.It is estimated that it won't be long before Jiang Chen's Little Bird helicopter will be able to use this domestic engine.

What Jiang Chen and the others want to break through now is also the most concerned and important thing is the gas turbine engine. This kind of engine is the most widely used and the most important in the aviation industry.Types include turbojets, turbofans, turboprops and turboshafts, all having a compressor, combustor and gas turbine.Turboprop engines are mainly used for aircraft with a speed of less than 800 kilometers per hour, turboshaft engines are mainly used as power for helicopters; turbofan engines are mainly used for higher speed aircraft, and turbojet engines are mainly used for supersonic aircraft.It's just that this type of aviation gas turbine engine is a highly complex and sophisticated thermomechanical engine that provides the power needed for aircraft to fly.As the heart of an aircraft, it is known as the "Flower of Industry". It directly affects the performance, reliability and economy of an aircraft, and is an important manifestation of a country's technological, industrial and national defense strength.No matter at present or in later generations, the only countries in the world that can independently develop high-performance aero-engines are the United States, the Soviet Union/Russia, the United Kingdom, and France, and the technical threshold is very high.

Moreover, Jiang Chen also knows that because the manufacture of this type of engine is rare and very high, the meaning contained in it is of great significance in terms of civil use and social and economic development, as well as military and national defense.It is precisely for this reason that the world's major manufacturers of such engines have always kept a high degree of confidentiality and strictly restricted the R&D and manufacturing technology of aviation gas turbine engines.Coupled with the vigilance and restrictions of these countries on our country, the development of aviation gas turbine engines in our country has been stagnant, and the research and development work is very difficult.This has put a curse on the development of our country's aviation industry and severely restricted the development of industries and technologies in this area.It is also for this reason that our country's air force aircraft have long relied on imported engines from abroad and are controlled by others.Some people jokingly call this phenomenon the 'heart disease' of our planes.

In order to come up with our own aviation development "fighting machine", many scientific research work in the aviation industry.We went on and on and worked hard until the first 20 years of the new century, when the country increased its attention and investment in this area.And the great progress of our country's national defense industry has made our own aviation gas turbine engine technology see the light of day.But it is also a very young seedling. Under the care of those who care about it, it is growing hard to cope with the wind and rain from the outside world.

Knowing this, Jiang Chen naturally attaches great importance to the development of our aero-engine.So he is very eager to use this period of time and the special opportunities he has encountered to contribute to the development of our country's aviation gas turbine engine technology and save some regrets.Therefore, under the strong push of the government, the aerodynamic research and development laboratory for this type of engine development work was also quickly established.Now an aviation gas turbine engine research and development team led by Mr. Liu is conducting research on such related technologies here.To be proud, this may be the largest and most invested aviation gas turbine engine technology research and development center in China during this period.Although other related research and development institutions during this period also engaged in research in this area, they were all single and scattered, far from being comparable to this one.Besides, the current capital investment is also incomparable with this place.

Even so, the research work here is still going on with difficulty.No way, the technology involved in this type of engine is very complicated, including materials, finishing, heat treatment, aerodynamics, fly-by-wire control and other technologies. It can be said that it will not be successful for a while.And Jiang Chen knows that this is a long-term huge project, and there will be no results in more than ten years.But he is not in a hurry, he is still young and can afford to wait, and this country and this army are also young and can afford to wait and look forward to it.
