The aircraft and aircraft project, which was a very cutting-edge project, almost came to a standstill after the internal combustion engine was blocked, except for the balloon project.

It is a purely theoretical study, they don't know, whether the internal combustion engine has the possibility to achieve, but the magic created by Zhao Xin, in the Dinghai, especially in the research system, is very powerful, in science and technology, he is almost mythologized, it says that there is such a research institute, there is really such a research institute.

They all hope that the internal combustion engine can be completed quickly, but in fact, the laboratory of the internal combustion engine is really there, and the time to establish it is far longer than the research of the aircraft, and the investment of manpower and material resources is also higher.

The internal combustion engine, which is a systematic project, is the power system after the steam engine, and his appearance, to a large extent, replaces a large number of steam engines, and innovates and has more uses.

The project of the internal combustion engine is in the research of the steam engine, which has entered to a similar extent, and this is what it enters, compared with the steam engine, the technical indicators of the internal combustion engine are higher, and there is one less intermediate link, which seems to save a lot, but the requirements for the entire component have been improved a lot.

The combustion chamber, pistons, power system, and even the whole, its performance is much better than that of the steam engine, and of course, the power is also improved a lot.

Dingjun, the knowledge of machinery is relatively weak, but through the steam engine accumulated a part, on the basis of the steam engine, also basically perfected some basic theories of the internal combustion engine.

The general internal combustion engine is a way of mixing liquid, mostly gasoline, diesel or kerosene, with huge heat, with air in a certain proportion, into the combustion chamber for combustion, generating heat through deflagration, and then converting the heat into kinetic energy.

It sounds very simple, but as far as a combustion chamber is concerned, the steam engine can use a dry pot and refractory materials to make the combustion chamber, but the internal combustion engine is not good, his combustion chamber must be integrated with the internal combustion engine.

Heat is converted into kinetic energy, this initial time, you can use hot air to expand, drive the power unit to work, this is the initial conversion, in the future, there may be some more excellent, but now in the research stage, the performance of the internal combustion engine is not so high.

However, after years of research, especially in the development of steam engines, the gradual improvement of mechanical and conduction experience, the progress of the internal combustion engine began to accelerate.

After years of public relations, coupled with a little luck, the prototype of the internal combustion engine has been developed a few months ago, and after further improving some basic theories of the internal combustion engine, further modifications have been made, and the first practical internal combustion engine has been produced on the basis of the prototype.

Prototype and practicality, these are two concepts, some machines, these two concepts are unified, but in the study of the internal combustion engine, these two concepts are separated, the prototype, is as open as possible, to achieve the basic function of the internal combustion engine, in order to facilitate observation, this is at most the theory of testing, do not have the ability to actually do work, through this, after further improving the basic theory, it is the construction of the first practical machine.

Even after so many years of research, even on the basis of the prototype, the old and the new, and further strengthen the performance, the overall performance of this internal combustion engine is not high, but from the basic aspect, his performance has been completed in the steam engine, especially the weight, in the case of the same power, his overall weight is about one-tenth of the steam engine, plus combustion and air, the reduction is even more.

Of course, so far, the internal combustion engine is not simply for the flight project service, he involves several major aspects, for example, in the railway, the train with the internal combustion engine as the core, of course, can not directly use the internal combustion engine, and the steam engine is slightly different, the energy of the internal combustion engine, the impact is stronger, although the kinetic energy is higher, but the continuous stability is not good, the first step of combustion and the second step of the third step, the part that stops in the middle, is particularly obvious.

Put it on the ordinary small motor vehicle, it is not too conspicuous, but on the train, it is not very suitable, you must add a conversion, the conversion of the train can be used, relatively stable.

Generally, it is divided into mechanical transmission, hydraulic transmission and electric transmission, but now the internal combustion engine has not been thoroughly studied.

The study of the internal combustion engine represents that the Dinghai Navy has entered a new era in terms of dynamics, and the internal combustion engine with more powerful efficiency is very widely used.

Zhao Xin's prevention made the Aircraft Research Institute, which was making great progress in itself, come to an abrupt end, from the combination of theory and practice to pure theoretical research, even if there was Zhao Xin's suggestion, it suddenly became empty.

Although the aircraft is said to be a model of heavier than air, it is highly controllable, easy to operate, and the most important thing is the military use, which is very prominent.

Aircraft need to be in the field of engines, at least the internal combustion engine research to a certain extent, Zhao Xin recorded a lot of classic aircraft shapes, and can even avoid the earliest kind, directly use relatively strong wood, to form an airplane, that is a more mature aircraft.

Constantly drawing drawings, making models, and even sending models to special machines, although it is said that the internal combustion engine cannot be made, but it is still possible to provide a certain kinetic energy, give the model a certain speed, and test the laughter of lift-off.

However, their luck is good, the internal combustion engine project, after many years of unremitting efforts, finally completed in the recent research, produced the first prototype, and the prototype at the same time, there are special personnel, a series of research and experiments on the prototype, and summarize the lessons learned, to ensure the next research and development.

At the same time, some data of the prototype was also sent to various associated laboratories, including the aircraft laboratory. They have been waiting, and in the past few months, they have also conducted a series of experiments, and on the basis of the experiments, they have made some designs, and now, they can substitute this data into it.

Researchers are already very familiar with the various indicators of power, in fact, the first time the data is sent, I feel that this data is not very good, but it is still substituted into the calculation, and finally a result is obtained, when the result comes out, everyone's first reaction is a calculation error.

After waiting for such a long time, I got the first practical internal combustion engine, I thought that its performance in all aspects, it would be as good as expected, but from the data obtained now, bring these powers into the flight formula, the speed of take-off and detachment, will be reduced to between 350 and 380, which is still a very high number, but compared with the previous, more than 800, or even higher, the improvement is not a little bit and a half, but as far as the aircraft experiment is concerned, It's still a very difficult number to achieve.

In the Aircraft Research Institute, there is only one prototype data, and this prototype is not very suitable for loading on an airplane, but they still have to make an effort, that is, to strive for such a prototype.

The laboratory of the internal combustion engine is responsible for many projects, aircraft experiments, only one of them, or one of the very unimportant ones, more important, the new generation of diesel locomotives, as well as the research of various motor vehicles, this is the most important.

The former represents the railway, the latter represents the road, and as for the airplane, although it also represents a means of transportation, at present, the means of transportation flying in the air are not yet in the overall concept, and therefore do not have much importance.

It is not very difficult to replicate the scientific research system of the navy as long as the prototype and the first generation of practical internal combustion engines are made.

The Aircraft Research Institute, first of all, let the internal combustion engine here, provide the physical object, of course, the internal combustion engine can, but it takes time, about two weeks, for this, the aircraft laboratory has no way, when booking a steam engine, let the internal combustion engine research institute confirm the various indicators of the internal combustion engine.

Dingjun is very rigorous in scientific research, not only forming a set of scientific methods in scientific research, but also forming a rigorous scientific research system.

The Aircraft Research Institute, which has now studied a considerable part, is only one step away, and of course cannot retreat in this situation, and when we get all the data, when we get the speed of 350 kilometers, we will begin to make difficulties, how to achieve this speed.

The source of speed is power, as long as there is enough power, under certain circumstances, it is not difficult to achieve speed, according to reason, as long as there is enough power, this speed can be achieved.

But there is a premise, as long as it is on the earth, it will be affected by air resistance, as well as friction, friction is good, resistance is good, the former is related to weight, the heavier the thing, the more friction will be generated.

The latter, although not related to weight, but with volume, and aerodynamic structure has a relationship, these two indicators, have a curve, blindly increase the power, will bring a sharp increase in weight and volume, it seems that the power will continue to grow, but to a certain extent, almost inevitably, will produce a limit, in the increase in the power of the benefits, not only will not let the speed increase, but will reduce the speed.

The reinforced concrete structure, and then the surface is smoother, and when the polishing is quite smooth, the resistance on the ground will be reduced, so the use of a flat runway can solve this problem, which is also Zhao Xin specifically mentioned in the aircraft design.

Cement runway and some asphalt runway, as smooth as possible to reduce friction, so that to a certain extent, to obtain sufficient speed, relative to the friction of the ground, the air resistance is the key, the aerodynamic force and air resistance of the aircraft is the biggest problem.

Because of this, it is difficult for a vehicle in the form of a vehicle on the ground to exceed a certain speed, even if it can fit so much power.

All aspects of the internal combustion engine, is already very normal, at least not as outrageous as the steam engine, relative to the speed of 800 kilometers per hour that can never be reached, 350 kilometers, that is a can be considered, at least, according to the calculation, the ratio between power and friction, air resistance, has not reached the limit, as long as the consideration, fill enough power, can be barely achieved.

Just when the aircraft laboratory was carrying out substantial design work on this data, in the internal combustion engine laboratory, there was good news, in the continuous experiments, as well as in the basic theoretical research, there was good news, the performance of the internal combustion engine has increased by 5% compared with before.

A 5% increase in performance means that the take-off speed may be reduced to 340 kilometers per hour, which is not much, but it is a revelation for the aircraft research institute.

In the previous design, because the data of the internal combustion engine did not come out, Dinghai had made a series of designs, in this design, the data of some internal combustion engines were very prominent, and the lowest time, the take-off speed was even only 150 kilometers.

For the basic data of the internal combustion engine, if the take-off weight is 150 kilometers, it is not difficult to achieve, and even if there is such an internal combustion engine, relying on the existing conditions, it can directly make an aircraft that can take off.

It's a pity that the data of the internal combustion engine is far inferior to this, and the researchers didn't think much about it at the time, but when the performance improvement of the internal combustion engine was provided, they remembered that the mechanical thing will improve, just like the steam engine, the performance at the beginning, and the current performance, is already a difference between heaven and earth.

Perhaps, the proportion of progress of the internal combustion engine will not be as prominent as that of the steam engine, but as long as it is doubled, it will basically reach the scheme they designed, and it is not very difficult to achieve this speed at a take-off speed of 150 to 180 kilometers on a fixed, high-quality runway, so that a practical aircraft can be built.
