The aircraft and aircraft project, a very cutting-edge project, has almost stalled after the internal combustion engine was blocked, except for the balloon project.

It is the study of pure theory, they do not know whether the internal combustion engine has the possibility of reaching, but the magic created by Zhao Xin, in the fixed navy, especially in the research system, the power is very high, in science and technology, he is almost mythical, it says that there is such an institute, there is such an institute.

In not knowing when, can be able to produce the internal combustion engine, then the research progress of the aircraft, can only be carried out, they all hope that the internal combustion engine can be quickly completed, but in fact, the internal combustion engine laboratory is still really, and the establishment time, far longer than the research of the aircraft, the human and material resources are higher.

The internal combustion engine, which was a systematic project, was the power system after the steam engine, and his appearance, to a large part, replaced a large number of steam engines, and introduced new ones, with more uses.

The project of the internal combustion engine is in the study of the steam engine, into the same degree, which entered, compared with the steam engine, the internal combustion engine technical indicators are higher, less an intermediate link, seems to save a lot, but for the requirements of the entire component, it is improved a lot.

The combustion chamber, piston, power system, and even the whole, its performance is much higher than that of the steam engine, of course, the power above, but also a lot.

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

The general internal combustion engine is the liquid, mostly the heat of gasoline diesel or kerosene, through a certain proportion of the mixture with the air, into the combustion chamber to burn, through the explosion to produce heat, and then convert the heat into kinetic energy of a way of working.

It sounds simple, but for a combustion chamber, the steam engine can be used as a dry pot, with refractory materials to make a combustion chamber, the internal combustion engine is not enough, his combustion chamber must be integrated with the internal combustion engine, in this case, the material put forward higher requirements, high temperature resistance, corrosion resistance, at the same time, the strength also has.

Heat is converted into kinetic energy, this initial time, you can use hot air to expand, promote the power device to work, this is the initial conversion, 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 the steam engine, the gradual improvement of the mechanical and conductive experience, the progress of the internal combustion engine began to accelerate, of course, the advantages of the Navy's material science, but also in the internal combustion engine project on the play to the fullest.

After years of public relations, coupled with a little luck, the prototype of the internal combustion engine has been completed a few months ago, after further improving some of the basic theory of the internal combustion engine, began to further modify, on the basis of the prototype, the first practical internal combustion engine was produced.

Prototype and practicality, this is two concepts, some machines above, the two concepts are unified, but in the study of the internal combustion engine of the Navy, the two concepts are separate, the prototype, in the most open state, to achieve the basic efficacy of the internal combustion engine, to facilitate observation, this is the most theory above test, do not have the ability to actually do the work, in the passage of this, after further improving the basic theory, is the complete construction of the first practical machine.

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

Of course, so far, the internal combustion engine is not just for the flight project service, he involved in several large aspects, for example, in the railway, the internal combustion engine as the core of the train, 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 force is stronger, although the kinetic energy is higher, but the continuous stability is not good, the first step of the third step, the middle stop part, especially obvious.

Put on the ordinary small motor vehicle above, not too conspicuous, but placed on the train, it is not suitable, must be added to a conversion, converted into the train can be used, more stable can be.

Generally divided into mechanical transmission devices, hydraulic transmissions and electric power transmissions, but now the internal combustion engine has not been thoroughly studied, these are later words, also the same as the aircraft research institute, in the slow accumulation of experience.

The internal combustion engine is developed, representing the Navy in terms of dynamics, entering a new era, more powerful internal combustion engines, and the use of a very wide range, after all kinds of internal combustion engines in every area of daily life, will appear on all sides.

Zhao Xin's prevention, so that its own high song of the aerial vehicle research, suddenly stopped, from the combination of theory and practice, into pure theoretical research, even if there is Zhao Xin's mention point, but also suddenly become virtual.

Although the aircraft is a model of heavier than air, it is highly controllable and easy to operate, and the most critical is the military above the use, very prominent.

Aircraft need to be in the field of the engine, at least the internal combustion engine research can reach a certain extent, Zhao Xin recorded a lot of classic aircraft modeling, even avoid the earliest kind, directly with relatively strong wood, constitute the aircraft, that is more mature aircraft.

Constantly drawing drawings, making models, and even sending models to special machines, although the internal combustion engine can't do it, it can provide a certain amount of kinetic energy, give the model a certain speed, and test the smile of the liftoff.

However, their luck, the internal combustion engine project, after years of unremitting efforts, finally completed in the recent research, made the first prototype, and the prototype in the same time, there are special personnel, the prototype to carry out a series of research, experiments, and lessons learned to ensure the next research and development.

At the same time, some of the data of the prototype was also sent to the associated laboratories, including the aircraft laboratory.They have been waiting, in the past few months, have also carried out a series of experiments, and on the basis of the experiment, some design, can now, put this data into.

Researchers, for the various indicators of power is already very familiar, in fact, in the first time in the data sent, it is felt that this data is not very good, but still into the calculation, and finally got a result, when this result came out, everyone's first reaction, is the calculation error.

Wait so long, to get the first practical type of internal combustion engine, I thought that all aspects of its performance, will be as good as previously expected, but from now to get this data, these power into the formula of flight, the speed of take-off, will be reduced to 350 to 380, or a very high number, but compared with the previous, more than 800, or even higher, the improvement is not a little and a half, but in terms of aircraft experiments, it is still a very difficult to achieve the number.

The Aircraft Research Institute, only a prototype data, this prototype, is not suitable for the aircraft, but they still have to work hard, that is, to get such a prototype.

The internal combustion engine laboratory is shouldered by many projects, the experiment of the aircraft, just one of them, or one of them is very unimportant, more importantly, a new generation of internal combustion engine locomotives, as well as a variety of motor vehicle research, this is the most important.

The former represents the railway, the latter represents the road, and as for the plane, although it also represents a means of transportation, but in the present, the means of transport flying in the air, in the overall concept, do not have much importance.

The Navy's scientific research system, as long as the prototype, the first generation of practical internal combustion engines to be made, and then replicating is not a very difficult thing.

The aircraft research institute, first let the internal combustion engine side, provide physical, internal combustion engine is of course, but it takes time, about two weeks or so, for this, the aircraft laboratory is also no way, when booking a steam engine, also let the internal combustion engine research institute, confirm the internal combustion engine indicators.

The Navy is very strict for scientific research, not only formed a set of scientific research methods, but also formed a rigorous scientific research system, any scientific research data, his accuracy or not, are responsible, once again asked the data, get, of course, the same answer.

The Institute of Aircraft Research, which has now studied a considerable part, is only one step away, of course, this situation can not be withdrawn, in getting all the data, in getting 350 kilometers of this speed, began to trouble, how to achieve this speed.

The source of speed is power, as long as there is enough power, in a certain situation, the speed is not difficult to achieve, according to the reason, as long as there is enough power, can fully achieve this speed.

But there is a premise, as long as on the surface of the earth, it is subject to air resistance, as well as the impact of friction, friction is good, the resistance is good, the former has to do with weight, the heavier the thing, to move up, the greater the friction.

The latter, although not related to weight, but with the volume, with the gas dynamic structure has a relationship, these two indicators, there is 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 inevitable, will produce a limit, in the increase of the power benefits, not only will not let the speed increase, but will make the speed down.

Reinforced concrete structure, and then the surface to make a little flat, when the polishing is quite smooth, the ground on the resistance will be reduced, then the use of a flat runway, you can solve this problem, this is also Zhao Xin on the aircraft design above, specifically mentioned.

Cement runway and some asphalt runway, as far as possible flat to reduce friction, so that a certain extent, to obtain enough speed, relative to the friction of the ground this, air resistance is the key, the air power and air resistance of the aircraft is the biggest problem.

Because of this, a vehicle in the form of the ground is difficult to exceed a certain speed, even if it can be plugd down so much power, it can not be.

The internal combustion engine indicators, has been considered very normal, at least not as far away as the steam engine, relative to the speed of 800 kilometers per hour that can never be reached, 350 kilometers, it 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 reluctantly achieved.

Just in the aircraft laboratory, when substantive design work is being carried out for this data, in the internal combustion engine laboratory, there is good news, in the continuous experiments, and in the basic theoretical research, there is good news, the performance of the internal combustion engine has increased by 5% compared with the previous one.

The 5% performance improvement, which 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 internal combustion engine data did not come out, the Navy has done a series of designs, in this design, some internal combustion engine data is very prominent, the lowest time, the take-off speed is 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, you can directly make a plane that can take off.

Unfortunately, the data of the internal combustion engine is far less than this, and the researchers did not think much about it at that time, but when the performance of the internal combustion engine was improved, they remembered that this kind of thing would be progressing, just like the steam engine, in the initial performance, and the current performance, it was already a difference between heaven and earth.

Perhaps, the proportion of the internal combustion engine progress will not be as prominent as the steam engine, but as long as it is doubled, it basically reaches their design, at a take-off speed of 150 to 180 kilometers, in a fixed, high-quality runway, to achieve this speed, it is not difficult, then the practical aircraft can be built.
