Regarding the research work of helicopters, the next step is to start using graphene and some advanced materials to replace the current materials. This process is a gradual process, which requires a lot of tests to ensure that there are no mistakes in the design, and the strength structure of the parts can also meet the design requirements.

"The rotor beam still adopts the current structure, but the fiberglass skin on the outside can be studied in the direction of graphene, so that the quality will be lower and the strength will be better..." Liu Yijiu told Liao Zhuojing and others.

"And, the engine improvements must be carried out. Our current engines are all built on the tv3117 turboshaft engine used by Mi24 helicopter. Although the power exceeds the original single power and reaches 1,804 kilowatts, which is 2,453 axes, it is obviously quite different from our design requirements." The engine is a serious backward project of the Republic.

In Mi24's original design manuscript, almost all the information is complete.

The ability to obtain the original design manuscript of the Mi24 helicopter in a short time and copy these key parts in a short time is very proud of, and it also surpasses the original design.

However, Liu Yijiu is not satisfied with the current engine power.

The two engines with a maximum power of 1,800 kilowatts will not show the lack of power of this engine when there is no weapon system added.

Once the engine is hung according to Liu Yijiu's idea and a squad of soldiers is required, it is very likely that the helicopter cannot fly. After all, the fuselage of the 91 is much larger than that of the 24 meters, and the dual-rotor coaxial design has greatly improved the stability of the helicopter. Where is the ceiling, what is the maximum speed, what is the cruise speed, and whether it is stable during flight, all of which must be gradually known during the test.

The maximum take-off weight is what Liu Yijiu wants to know the most.

At the beginning, the design required the helicopter to reach 15,600 kilograms, which was 4 tons more takeoff weight than the 24 m2. The engine power was only increased by 10%.

Not enough at all.

But now they have to produce prototypes for test flights.

At worst, just carry less external weapons at that time. When the new high-power engine is developed, they will directly replace them with two powerful hearts. This helicopter is guaranteed to have super strong performance just like taking Dali Jingang Pills.

"Director Liu, we will continue to work hard on the engine. But is the design of our helicopter a bit waste?" Liao Zhuojing's mouth twitched.

Liu Yijiu shook his head, "It's not a waste. This design is more practical. The transport helicopter has self-protection capabilities and can effectively provide air firepower to the ground armored forces. At that time, we hang our black arrow missiles on the belly, install anti-tank rocket nests on the hangers on both sides, and then install air defense tanks specifically used to attack the opponent's helicopters or fighters... The multi-barrel machine guns in front are specially used to massacre infantry."

Transportation is one aspect, and fire support is the most important thing.

The reason why a huge fuselage is designed is to obtain a huge warehouse. When installing a weapon system, it is an armed transport helicopter. If transportation capacity is not required, the warehouse can be improved into an ammunition storage warehouse. The load capacity of several tons of ammunition is completely an air weapon warehouse, and it has become a super armed helicopter in the complete sense.

Even, it can be like a prototype that is now a test flight. It does not require any weapon system to be hung, and it is a complete transport helicopter.

This design scheme has far more development potential than Mi24.

However, it is too large and requires excellent protection. The helicopter's shell needs to be equipped with very thick defensive armor, otherwise this thing will become a moving target in the air, and a rocket can turn this thing into a pile of scrap iron.

Just this helicopter, once improved to the ultimate form in Liu Yijiu's mind, will allow the Republic to be used for at least fifty years.

"And there is another biggest advantage, that is, our current helicopter pilot training system is not sound, the number of pilots is not large, and the country has no money to equip too many continental aviation groups on a large scale. Our multi-functional helicopters are specially designed for the situation of the country..." Liu Yijiu fooled these old men.

That's how it is.

The country is very poor.

We cannot purchase helicopters with very professional designs and fine division of labor to equip the troops. This kind of multifunctional one that can quickly change the purpose of the aircraft is China's best choice.

It is also the best choice for all the poor countries in the world.

"But our weapon system and the weapon disassembly system are not a small project..." Liao Zhuojing refuted Liu Yijiu. He always felt that Liu Yijiu had selfish intentions in this.

He didn't know what kind of selfishness Liu Yijiu was.

"So, our next improvement plan and direction, no, or when we finalize the helicopter, we need a modular design. The front multi-barrel machine guns do not need to be disassembled, and even the transport aircraft, we have to make them attack capabilities. The subsequent weapons and equipment must be modularly designed, and once needed, our helicopters can transform their morphological functions in a short time..."

Modular design, this is a must.

This is true for tanks and helicopters.

It is best to make each module common, which can effectively reduce the pressure of logistics support.

In the future military development, the more advanced the equipment, the more NB troops, the more logistical support they need. Otherwise, the combat effectiveness will be greatly reduced. The logistics construction of the Republic is far from keeping up with Europe and the United States, and these issues must be considered when designing weapons and equipment.

Liu Yijiu kept instilling the weapons design principles and development ideas of the mid-to-late 21st century into his designers.

"Okay, you can continue to work later. The next test flight will probably take ten days and half a month. I will guard it myself at that time." Liu Yijiu solved the problem and could not continue to delay time in the base.

The Soviets probably were impatient to wait.

What's more, the first college graduates who resumed the college entrance examination after the chaos are about to graduate.

Logically speaking, it is already May, and the allocation of graduates from major universities has been implemented. Liu Yijiu and others should have worked hard in this area for a long time, but he has no time. Anyway, he has the fancy to these college graduates, no matter what unit the other party is, he has to grab it.

As for the students not willing?

Nowadays, college students are allocated by the state, and they can go wherever they are, otherwise their future will be over.

This is much easier to handle than college graduates decades later.

"Director Liu, don't forget that we are short of people here. The University of Aeronautics and Astronautics is your alma mater, especially the good seedlings under your teacher. Just get us a few more..." Seeing that it is getting late, Liu Yijiu doesn't seem to care much about technical matters. Apart from mobilizing more than 20 people from the Institute of 611 to supplement the helicopter research team, none of them are the others.

Moreover, the average age of the research team in the base is over 40 years old, which is very unfavorable to the sustainable development of the entire project team.

Liu Yijiu didn't expect that these guys were more concerned than themselves, and smiled and reassured them.

He took a slow 5th from the base again to Rongcheng. The pilot asked Liu Yijiu when he would fly to the helicopter studied in the base. Liu Yijiu smiled and said nothing, telling the pilot who was in his forties that when the test flight was achieved, he could hand it over to Longya for trial first.

The specific time has not been determined.

"Brother Jiu, the first batch of college students were not enough to learn, and not to mention whether they learned anything in school. All the units in China are staring at this group of graduates. If we snatch all the people that others have already liked, will we offend too many people?" Li Rui knew Liu Yijiu's purpose.

He was full of worry. If Liu Yijiu offended everyone in the system again, anyone who encountered a chance in the future would stab him from behind.

"Don't worry, I know this. In fact, the main ones who robbed were from the University of Aeronautics and Astronautics, Huaqing University, North China Polytechnical University, University of Science and Technology and other units. My teacher and I paid attention to all the appropriate talents. Now there is no arrangement for their graduation assignments." Liu Yijiu smiled proudly.

There are absolutely benefits to having many teachers.

After returning to Qian Xuesen's home, Liu Yijiu reconnected with his many teachers.

You should know that these teachers are basically the most top academic authority in China in that field. The students they teach are naturally the best.

Regarding the help from the students who have only been with them for a year, as well as the greetings from Comrade Qian Xuesen, and the hint from Minister Li Yunlong, major schools will naturally not take action.

"Are you thinking about the junior class of the University of Science and Technology of China? After all, they are all children. Although you have been in the base all your life, they should not be like this. They should have a choice." Li Rui suddenly plucked up the courage and said to Liu Yijiu with gritted teeth.

The oldest children in the Junior Class of University of Science and Technology were only 15 years old when they entered school, and the youngest was only 11 years old. Most of them are not yet adults.

Liu Yijiu's idea was to let all the students in the teenage class be admitted to the Ninth College

It is also filled in various relevant units of the Ninth Hospital as the main successor training.

Ten years later, the old group of scientific researchers retired, and the entire base will be responsible for the work of these growing children.

This is a very sad and cruel thing.

At least, Li Rui felt that. She felt that those children should have a choice, and they could go out of the mountain... to be continued.
