However, it is impossible for Li Zhao to say this kind of thing, so he can only explain it to Su Ya from other aspects, as for the engine of the helicopter, it can only be designed slowly in the future, but this speed is estimated to be not too fast.

Li Zhao also explained at this time: "That plane is actually not as advanced as you think, but our country has been in contact with aircraft research for a relatively short time, and has not formed effective research ideas, and is still in the stage of imitation and learning.

Li Zhao said this, of course, for the sake of An Suya's heart, of course, how advanced that aircraft is, it is indeed not very advanced, after all, on the whole, the electronics and weapon systems will be quite backward, but the materials are definitely very advanced, in terms of the high-temperature alloy used in the engine, it is at least thirty or forty years ahead, and the factory is now reaching the temperature resistance limit, in fact, in foreign countries, it will take zero zero years to achieve.

Therefore, the material is the most high-tech thing in this aircraft, as for the engine mechanism and operating system, it can be stronger than the first generation at most, and the second generation is not necessarily advanced, compared with the technology after sixty years, it is completely incomparable, no matter how good Li Zhao's brain is, the accumulation is also limited, and the follow-up development is basically continuous accumulation, and the time required will be very long.

Li Zhao didn't wait for Su Ya to speak, and continued to explain: "In fact, the engine of the helicopter is still relatively difficult, let's put it this way, the helicopter engine we use now is actually enough power, but the problem is that the engine is too large in size and weight, and if you want to achieve a relatively large load, then you basically need to install two engines on the existing helicopter, so that it can't be installed directly, and if you want to achieve it, you must redesign the engine."

Su Ya also understood at this time, and said, "You mean, the engine needs to be designed to half the size of the existing one, and it also needs to have the current power, right, that is really difficult, no wonder you don't want to do it."

Li Zhao listened to Su Ya's understanding, and directly sneered, and explained for a while: "It's not what you think, it's necessary to design two engines that can be installed on the current helicopter, the specific size depends on the installation space, not directly designed to be half of the existing one, and in order to maintain it well, we also need to leave maintenance space, our current helicopter, its physical type is not small, and the problem now is the overall lack of power."

This is indeed the case, in fact, the helicopter produced now and the Black Hawk helicopter are about the same size, and the rotor area is larger than the Black Hawk helicopter, but the engine is one, and the Black Hawk is two, and the power of each engine of the Black Hawk is just the same as the power of this helicopter, under two times the power, the empty weight of the two helicopters is not much different, and the performance can be imagined, but it is not easy to achieve the Black Hawk.

After listening to Li Zhao's words, Su Ya also knew the difficulty, but still said, "Anyway, you can think about it when you have time, you can't let Uncle Zhang sulk there all the time, after all, you agreed."

Li Zhao really smiled bitterly after hearing this, he has no reference for the helicopter, if he really makes this, it will depend on his own design, although he is quite confident, but it is definitely not something that can be solved in a short time, but how can he say this to others, he has now given outsiders an omnipotent image.

The next day, Li Zhao and Su Ya went to the medical research institute together, and when they arrived at the place, they soon visited the laboratory with the person in charge, and the two of them understood the extraction process in detail, and looked at the research process of other drugs.

Looking at this situation, it is estimated that it will not take long for these to succeed, after all, the research is successful, then the process is almost explored, and other studies are not much difficult, now the difference is just time, given enough time, then there is basically no possibility of unsuccess.

Li Zhao couldn't help but ask, "Have you designed the corresponding production equipment and production process?"

Only by taking out the production equipment and the corresponding technological process can we quickly transform scientific research into products, otherwise it is just an achievement

It's just that it is difficult to change the current situation of lack of medical care and medicine, and it is meaningless.

After listening to Li Zhao's question, the person in charge replied directly: "We have studied it with several research institutes such as machinery, the process has been determined, the equipment is being designed, it should not take long to come up with a specific design, and we have now applied for a clinical trial with the health system, and we can conduct clinical trials after approval, and there will be no problem with this product."

Li Zhao nodded after listening, he didn't know much about medicine, and now he looked at the person in charge of the research institute with a determined look, obviously full of confidence, but Li Zhao was not satisfied with the current research results, so he said: "Have you ever thought that through the study of prescriptions, find out the ingredients that really work on certain diseases, so that maybe they can be made into drugs through chemical synthesis, so that the cost is estimated to be lower."

In fact, many plant components can be directly synthesized, among which the more famous such as salicylic acid, which is rich in willow bark and has an analgesic effect, the scientific name is o-hydroxybenzoic acid, obviously when producing, it is the stupidest way to boil willow bark, and when chemical synthesis, the original raw material is toluene, which can come from petrochemical industry, which can reduce the cost to the point of outrageous.

It is obviously very expensive to rely entirely on traditional Chinese medicine, and even if the method of artificial cultivation of Chinese medicinal materials is adopted in the future, the cost is very high, and the mass production of chemical synthesis cannot be compared.

Hearing Li Zhao's proposal, the person in charge said: "Chief Engineer Li, this has already begun, but the progress is estimated not to be too fast, this is not the same as the development of Chinese patent medicine, as long as the Chinese patent medicine is determined to be not much different from the ingredients boiled out of the test formula, and there are no side effects, it is basically the same, but if you want to extract the real active ingredients, it will take a lot of time to screen, and you are most afraid of multiple ingredients working together."

Obviously, these people are professional, in terms of their profession, it is obviously incomparable to Li Zhao, they obviously consider it very comprehensively, and they also take into account the possible joint action of a variety of ingredients, but now it seems that the research is progressing quite smoothly, although I don't know where the road of artificial synthesis can go, but obviously in the next period of time, Chinese patent medicine will definitely soon enter the life of the public.

For a period of time, the development of the factory in medicine is quite good, first of all, the expansion of the pharmaceutical factory, although Li Zhao did not participate much, but the progress is really fast, by the end of the year, such as penicillin production capacity is at least several times, this is still the factory needs to train the corresponding workers, can not be overnight expansion caused.

And now that there is Chinese patent medicine, as long as it is put into production, then the pharmaceutical status of the factory will be laid. Li Zhao, who was very satisfied with this, couldn't help but ask, "Do you still have any difficulties?"

However, the answer made Li Zhao embarrassed, so he heard the person in charge say: "Chief Engineer Li, the main reason for the difficulty is that we lack manpower, our researchers are part-time doctors in the hospital except for some people in the pharmaceutical factory who are full-time, and the others are part-time doctors in the hospital.

Hearing this request, Li Zhao could only smile bitterly and said, "The number of personnel that our factory can allocate every year is also limited, and where we want it, we can get it, I really don't dare to guarantee you this question."

The person in charge also sighed at this time and said, "Now that we have found a way, we lack manpower to test the test formula, which can easily produce results, and now there is a shortage of manpower."

Li Zhao naturally knew about this, but he really didn't want people, but after thinking about it, Li Zhao said: "College students, we are not coming, but the college entrance examination is coming soon, we can recruit some high school students to train, they may not be able to come up with any research results, but it should still be possible to do some experiments according to the arrangement, and when recruiting people, you can choose the corresponding subjects with better results, and we can still train these people."

"In addition, it is the same to go to the demobilized soldiers to pick up those with a high level of education and those who have learned the corresponding subjects well

Training, as you know, the night school of the army stationed in our factory is relatively well organized. Finally, you can contact the school in Beijing and provide internship or summer practice opportunities for college students, which can bring you some help, you can see which one is suitable, type the report, and try to cooperate with the factory."

Li Zhao's suggestion is quite pertinent, after all, the number of college students that can be allocated in the factory every year is really quite limited, and the medical research institute and the hospital can have so many twenty or thirty every year.
