In fact, it is not easy to be rich in materials, in addition to the introduction of policies to actively support the development of domestic agriculture, handicrafts, commerce, and service industries, the task of scientific research workers is the heaviest.

Because it involves all categories of the whole industry in society, and it is obviously not possible to unify the R&D department, Yang Wenli classified the scientific research department.

At present, because the number of people is still too small, only a simple classification has been carried out, which is divided into: electricity, motors, batteries, electromechanical, machinery, and materials.

Among them, because power and motor have related technologies and products, only a small number of personnel are retained for in-depth research and broaden the scale of products.

In both industries, only two people are left for in-depth research, which is equivalent to almost giving up, but not to make the technology cause a fault, which is no way, because other industries are more important.

The reason for setting up a separate battery research institute is that Yang Wenli sees that there are too few domestic scientific researchers, and plans to skip the era of internal combustion engines and concentrate on the research of high-efficiency mobile power technology, that is, lithium-ion battery technology.

Of course, this idea is very bold, it may not be possible, lithium-ion batteries are not so easy to develop, there may be no results in ten or twenty years, so only 5 scientific researchers are retained for initial research, that is, theoretical research, because there is no experience of predecessors, a lot of experiments need to be done, and these five people are unlikely to have any results, which is considered advanced pre-research.

The Institute of Mechanical and Electrical Engineering is more special, and their focus is on the study of mechanical and electrical equipment, especially large mechanical and electrical equipment, which is to make tools for themselves and constantly improve the level of mechanization in the Far Eastern Kingdom.

The scope of this electromechanical equipment is too broad, and it can be said that there are endless things to do, so this is a large department, with nearly 200 scientific research personnel.

The last classification of the mechanical research and development department is the department closely related to people's livelihood, such as the kind of soft roof shed European carriage, which is the product of the mechanical research and development department.

They are developing civilian products, not necessarily high-tech products, such as some very common tools, such as pliers, wrenches, screwdrivers, hammers, saws, smium, stainless steel cutlery knives, etc., but they all use high-performance alloy steel, although things are ordinary, the price is not cheap.

The mechanical sector is one of the largest departments, and all sorts of classifications are included in it, and the two most important departments are clocks and watchmaking and shipbuilding.

Clocks and watches are actually for shipbuilding, shipbuilding is a systematic project, and the Far Eastern Kingdom can only be a preliminary research now, mainly materials and processes, as well as the most difficult marine power.

The materials are mainly steel and paint, and the requirements for marine steel are very high, mainly to resist corrosion and have a high yield degree, which is not ordinary steel, but a real special steel.

There is also a polymer biomimetic material that can significantly increase the speed of the ship, just like seal skin, which has strong hydrophobicity and can effectively reduce the resistance of water.

Paint is a complete chemical field, this is a civilian product, very market prospects, not only ships, many industries to paint, this is an industry worthy of further study.

The shipbuilding process is mainly the welding process, and the welding process can also be widely used in all walks of life, which is an indispensable technology.

There are many kinds of welding technology, including ordinary electric welding, argon arc welding, oxygen welding, butt welding, etc., as well as advanced friction welding, laser welding, etc., which is also a university subject, and it is worth setting up a professional research team.

The last marine power is the biggest problem, in this period, there is no industry in all countries, but coal is generally on the surface, most countries have, and oil is generally buried deep underground, and there must be special oil equipment, other countries are not, even if it is Europe, so only the development of steam turbines, although the thermal efficiency of steam turbines is very low, but suitable, is the best.

I simply masturbated, everyone knows how arduous the scientific research task of the scientific research department is, and it is easy to have no scientific research results, which is the current situation.

However, some scientific research tasks are very urgent, such as shipbuilding technology, and one of the biggest shortcomings of the Far Eastern Kingdom is that the number of people is too small, especially the Han Chinese, which limits the pace of expansion of the Far Eastern Kingdom.

Thousands of miles from Ezo Island to the Central Plains, with ordinary wooden sailing boats, the first is that the time is too long, and the second is that the wave resistance of wooden sailing ships is too poor, and people with average health cannot sit on such a long sea route.

However, if modern steel ships are used, this difficulty can be overcome, and a large number of displaced people can be brought from Daming, and even the family members of Happy Valley can also be brought to Ezo Island, so Yang Wenli urgently needs to develop a modern high-speed large transport ship powered by steam turbines.

In fact, Yang Wenli split the scientific research department into several subsystems, which are mainly for shipbuilding technology.

At a routine marine steam turbine power technology seminar, Yang Wenli sat on the rostrum and made a speech: "The research and development of marine steam turbine is very difficult, we must divide the system, step by step solution, it is easier to have a high-pressure boiler, but this is not the kind of simple boiler we have developed before for heating, it requires a much larger boiler pressure, boiler steam to reach a temperature of more than 500 degrees, more than 100 atmospheres of high vapor pressure, which has higher requirements for materials and processes."

Second, because it is a marine boiler, it also has higher requirements for combustion efficiency, so that it can run farther with the same amount of coal, which ...... We envisage the combustion technology of refined pulverized coal, as well as the combustion technology of exhaust gas recovery, with the aim of maximizing the combustion efficiency.

The biggest problem is the development of the steam turbine, the most difficult thing in it is the turbine blade disc and turbine shaft, the turbine blade disc is mounted on the turbine shaft, to withstand high temperature and high pressure, its own weight can not be large, it is both light and high-strength, this is a contradictory whole, the requirements for materials are very high, and because it is working in a high-temperature steam environment, but also oxidation resistance, I envision high-strength stainless steel or aluminum alloy.

In addition, the turbine blade disc and turbine shaft are to rotate at high speed, we must do dynamic balancing, and each blade and each group of blade discs must be done to minimize vibration to improve stability and thus improve power output.

Another challenge is how to make the blades firmly fixed to the turbine shaft, which requires a high level of technology.

The last problem is beyond everyone's understanding, that is, fluid mechanics technology, which has a lot of knowledge, and also requires high-tech computing equipment and testing equipment, which we do not have for the time being, and I decided to take charge of the test myself, so I don't want those equipment.

Shipbuilding is not simple, and the development of modern steel-armored ships is even more not simple, we should not be afraid of difficulties, the technology we have mastered in developing ships is of great use in other aspects, in fact, it is more than one stone.

In addition, we must develop the ship as soon as possible, so as to pick up the family members who are still in the heart of the Ming Dynasty, only this kind of modern ship, can do it, the speed of the wooden sailing ship is too slow, the wave resistance is poor, the family members simply can not sit on such a long sea route.

All right! That's all for today's briefing, adjournment! ”
