Regarding the research work of helicopters, the next step is to start replacing the current materials with graphene and some advanced materials, this process is a step-by-step 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 girder is still in the current structure, but the outer FRP skin can be studied in the direction of graphene, so that the quality will be lower and the strength will be better......," Liu told Liao Zhuojing and others.

"Moreover, the improvement of the engine also has to be carried out. Our current engines are all based on the TV3-117 turboshaft engine used in the Mi-24 helicopter, although the power exceeds the original single power, reaching 1804 kilowatts, that is, 2453 shaft horsepower, obviously, this is still quite different from our design requirements. "Engines, this is a seriously backward project of the republic.

In the original design manuscript of the Mi-24, almost all the materials are complete.

The team was very proud to be able to obtain the original design manuscript of the Mi-24 helicopter in a short period of time and to reproduce these key components in a short period of time, and it went beyond 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 problem of insufficient power of such engines when the weapon system is not attached.

Once the engine is added according to Liu Yijiu's idea, and it has to carry a squad of soldiers, it is very likely that the helicopter will not be able to fly, after all, the fuselage of the Z-91 is much larger than that of the Mi-24, and the dual-rotor coaxial design is adopted, which greatly improves the stability of the helicopter. Where the ceiling is, how much the maximum speed can reach, how much the cruising speed is, and whether it is stable during the flight can all be gradually known during the test.

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

The initial design required the helicopter to reach 15,600 kilograms. 24 tons more than the Mi-4 more take-off weight. The engine power has only increased by 10 percent.

Not at all.

And now, they have to produce a prototype for test flights.

It's a big deal, when the time comes, just carry fewer external weapons. When the new high-power engine is developed, they directly replace it with two powerful hearts, and this helicopter is guaranteed to have super performance just like eating the Mighty King Kong pill.

"Director Liu, we will continue to work the engine. But isn't the design of our helicopter a bit wasteful? The corners of Liao Zhuojing's mouth twitched.

Liu Yijiu shook his head, "It's not a waste." This kind of design is more practical. Transport helicopters, with their self-defense capabilities, can effectively provide aerial firepower to the ground armored forces, and when the time comes, our Black Arrow missiles will be hung on the belly, and the pylons on both sides will be equipped with anti-tank rocket nests, and then equipped with anti-aircraft tanks specially used to hit the opponent's helicopters or fighters...... The multi-barreled machine gun in front is specifically designed to slaughter infantry! ”

Transportation is one thing. Fire support is the most important thing.

The reason why the huge fuselage was designed was to obtain a huge cargo compartment. When the weapon system is installed, it is an armed transport helicopter, and if there is no need for transportation capacity, the warehouse can be improved into an ammunition storage depot, and the bomb load of several tons is completely an air weapons depot. Turned into a super-gunship in the full sense of the word.

Even, it can be like the prototype that is now being tested, without attaching any weapon systems, and it is a complete transport helicopter.

This design scheme is far more promising than the Mi-24.

Merely. It's too big, it needs to be very well protected, and the helicopter's shell needs to be equipped with thick defensive armor, otherwise it will have to become a moving target in the air, and a rocket can turn this thing into a pile of scrap metal.

It's just that this helicopter, once it is improved to the ultimate form in Liu Yijiu's mind, will allow the Republic to use it for at least fifty years!

"Moreover, there is one of the biggest advantages, which is that our current training system for helicopter pilots is not perfect, the number of pilots is not large, and the country does not have the money to equip too many army aviation regiments on a large scale. Our multi-functional helicopter is specially designed for the country's situation......" Liu Yijiu flickered these old men.

That's the way it is.

The country is poor.

It is not possible to procure helicopters that are very professionally designed and have a very fine division of labor to equip the troops. This multi-functional one that can quickly transform the use of aircraft is the best option for the Chinese military.

It is also the best choice for the world's major poor countries.

"But our installation of weapon systems and dismantling of weapon systems is not a small project......" Liao Zhuojing retorted Liu Yijiu, he always felt that Liu Yijiu had selfish intentions in this regard.

What kind of selfishness Liu Yijiu is, he doesn't know.

"So, our next improvement plan and direction, no, or when we finalize the helicopter, is to need a modular design. The multi-barreled machine guns in front do not need to be disassembled, even if they are transport aircraft, we have to make them have the ability to attack. The weapons and equipment behind it have to be modularized, and once necessary, it can allow our helicopters to transform their form and function in a short period of time......"

Modular design, which is a must.

This is true for tanks, and it is also true for helicopters.

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

In the future development of the army, the more advanced the equipment and the more NB troops, the more logistical support will be needed. Otherwise, the combat effectiveness will be greatly reduced. The logistics of the republic are far from keeping up with Europe and the United States, and these problems must be taken into account at the time of the design of weapons and equipment.

Liu Yijiu constantly instilled the weapon design principles and development ideas of the mid-to-late 21st century into his designers.

"Okay, you guys continue the rest of the work, the next test flight is estimated to be ten days and half a month, and I will personally guard it then." Liu Yijiu solved the problem, and there was no way to continue to delay time in the base.

The Soviets are probably already impatient to wait.

What's more, the first batch of college graduates who resumed the college entrance examination after the great turmoil are about to graduate.

It stands to reason that it is already May, and the distribution of graduates of major colleges and universities has been implemented, and Liu Yijiu and others should have worked hard in this regard a long time ago, but he did not have time. Anyway, these college graduates, he took a fancy to them, no matter what unit the other party was, he had to grab them.

As for the students' reluctance?

In these days, college students are allocated by the state, and they can go wherever they want, otherwise, their future will be doomed.

This is much easier to do than college graduates decades from now.

"Director Liu, don't forget that there is a shortage of people here, the University of Aeronautics and Astronautics is your alma mater, especially the good seedlings under your teacher, get us a few more......" Seeing that it is not too early now, Liu Yijiu doesn't seem to care much about things other than technology. Except for the mobilization of more than 20 people from the 611 Institute to supplement the helicopter research team, there is no other.

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

Liu Yijiu didn't expect that these guys were more attentive than himself, and smiled to reassure them.

The pilot asked Liu Yijiu when he would be able to fly the helicopter being studied in the base, Liu Yijiu smiled, did not speak, and told the pilot, who was already in his forties, that when the test flight work achieved results, he could first hand it over to the dragon's tooth for trial.

The exact time has not been determined.

"Brother Jiu, the first batch of college students is not enough to study, and whether they have learned something in school is not said for the time being, all the units in China are staring at this batch of graduates, if we rob all the people that others have already taken a fancy to, will we offend too many people?" Li Rui knew Liu Yijiu's purpose.

is full of worries, if Liu Yijiu offends everyone in the whole system again, whoever encounters an opportunity in the future will stab him from behind.

"Don't worry, I know this. In fact, the main ones are people from the University of Aeronautics and Astronautics, Huaqing University, North University of Technology and University of Science and Technology. Liu Yijiu smiled proudly.

There are many teachers, and there are absolute benefits.

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

You must know that these teachers are basically the top academic authorities in China in that field. The students who bring it are naturally the best.

Regarding the request for help from this student who has only been with them for a year, as well as the greeting of Comrade Qian Xuesen, and Minister Li Yunlong's hint, the major schools will naturally not take action.

"The junior class of USTC, are you thinking about it? After all, they are all children. Although you have been in the base all your life, they shouldn't be like this, they should have a choice! Li Rui suddenly plucked up his courage and gritted his teeth and said to Liu Yijiu.

The oldest of the children in the junior class of USTC was only 15 years old when they entered the 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 of these juvenile classes enter the Ninth Academy!

Moreover, it is also filled into the relevant units of the Ninth Academy as the main successor training.

Ten years later, the old group of researchers will retire, and the entire base will be in charge of the work of these grown children!

This is a very sad, very cruel thing.

At least, that's what Li Rui thinks. She felt that the children should have a choice, that they could not go to the mountains...... (To be continued.) )
