The design subverted the traditional Z-91, the first flight had a problem, and the second test flight was a complete success!

It wasn't until half an hour later that the helicopter returned to the ground from the sky that Liu Yijiu breathed a sigh of relief. In particular, after various tests, it was confirmed that there was no problem in any part, and the breath was completely sent down.

All that remains is to continue the test flight, and it will be carried out at a high density.

Constantly load various weapon systems, carry out various tests according to different requirements, and after the test is completed, the limit test is carried out to test the helicopter's ceiling, climb performance, hovering altitude, etc.

"Now you are relieved? The production of the remaining three prototypes accelerated, and the weapon plug-in system had to be taken into account. There are also designs for magazines for various weapons. There is no problem with multi-functional use, but we must strengthen the fire system of these helicopters, armed transport, single transport, and simple armed helicopters, these three modes must be considered, so that the helicopter can have more functions...... "Liu Yijiu gave instructions to a cadre of management personnel and technical designers after the success of the first flight.

This is just a universal helicopter, and it is being carried out in a multi-purpose aspect.

"Director Liu, can't we use this for the Navy's anti-submarine work?" Liao Zhuojing frowned and asked Liu Yijiu.

This thing is a little too big.

The Navy of the Republic does not seem to have any warship capable of stopping this plane at the moment.

"That's a later thing, first understand the technology of this aircraft, after we are familiar with it, it is very easy to design an anti-submarine helicopter. As long as there are large warships, there will be no problem with the addition of anti-submarine systems at that time. It's a basic platform! Liu Yijiu said.

Anti-submarine?

The Navy is still very painful.

Not even a 053 ship has been completely done. Not to mention the 052 ship, which is still in the demonstration stage. Even if it's the 052 ship, it seems that it is still at the drawing stage?

The Admiralty is now waiting to pit Liu Yijiu, he is not so stupid, he will take the initiative to find the door and let the bigwigs pit him.

So, anti-submarine or not, it doesn't matter.

Later, when the Admiralty needs to talk about it, it will be said.

"Now we have to think about the loading of weapon systems. With what kind of weapon system. Which unit to cooperate with, this is what we need to face at the moment. We no longer design and develop weapons systems alone, but cooperate with our domestic brother units. Of course, their weapons and equipment need to meet the performance level we require......" At the seminar, after arranging the next step of the helicopter, Liu Yijiu proposed that they had to face the additional weapon system.

If possible, he would rather let the Ninth Academy go for research and development. But now there are too many projects in the Ninth Academy.

"Xiao Liu, the Black Arrow anti-tank missiles and Houyi anti-tank missiles in our base can all be used on this, and it is best to use anti-aircraft anti-tank missiles, and the weapon module will not have to be replaced before each different mission because of the different missiles carried. At the same time, our operating system will become much simpler. "As for what weapon system to load on it, Liu Yijiu, as the chief designer, originally considered it.

However. He can't dictate alone, and at some point he still has to get everyone involved, right?

Anyway, in the end, you have to pass his clap.

After all. He is not only the director of the Ninth Academy, but also the chief designer of the Z-91.

"Elder Qin, if you optimize, just say it directly. Use our missiles to use them, as for finding a reason for this? Liu Yijiu said with a wry smile.

Qin Yuan didn't feel embarrassed at all that he was exposed.

"Only by allowing our missiles to have a larger production volume can we effectively reduce costs, and the anti-aircraft missiles developed from the anti-aircraft anti-armor missile project technology are good. Whether it is an anti-armor missile or not, it has been well tested, and the next step should be our anti-aircraft anti-armor missile! It is impossible to test it on the battlefield, and it is impossible to know how much success our research results can achieve. If you don't behave well enough on the battlefield. Throw away this project as soon as possible and devote yourself to the research of professional subdivision technology...... Qin Yuan expressed his thoughts.

It stands to reason that the multifunctional missile with a tandem warhead for both anti-aircraft and anti-armor purposes studied by them should have more battlefield opportunities than the subdivided anti-aircraft missiles and anti-tank missiles.

However, now this missile has not been put into practice, and after each upgrade, it has not been tested several times, but it has been improved because the performance defects of the Black Arrow and Houyi missiles have been discovered and further improved.

Even, their multifunctional missile project has not been officially established! At the same time, this missile, without a code name, does not have a name.

The interior is called chicken ribs.

After all, if you want to be practical, and still achieve the kind of air defense and anti-armor that Liu Yijiu imagined at the beginning, and even carry a multi-functional missile with a high-explosive warhead to bomb infantry fortifications, and achieve the power he wants, according to the current technical conditions, it is necessary to produce a large number of missiles, and the cost exceeds their imagination, not to mention, no matter how powerful the infantry is, they cannot afford it.

Originally, it was based on the research of this missile to develop anti-aircraft missiles and anti-armor missiles, but now it is the other way around, so there is no name, no more energy inclination.

"If we use this ourselves, there will be no problem, but if we export ......" Liu Yijiu immediately shook his head.

The design of this kind of thing is not absent abroad, but it has not invested too much research.

It's like the internal name, chicken ribs!

for anti-armor, because it carries a high-explosive warhead, and considering the speed of air defense, the projectile body becomes elongated, which affects the armor-piercing ability; It is used for air defense, because it carries an armor-piercing warhead, and considering armor-piercing, the body of the projectile has to be thickened, which affects the flight speed.

Anti-helicopters are not a big problem, and it is estimated that they are not big to use to fight T72, but if they are faced with heavy tanks such as T64 and the American M1 or even the German Leopard 2, it will not work at all.

These missiles are not long enough, not fast enough, and air defense is also impossible to target fighters with speeds of up to Mach 2. After all, small-sized missiles. The speed of Mach 1 is a bit difficult, not only related to the design of the aerodynamic layout, but also related to the engine of the rocket.

Only when this piece is done can this missile be fully useful.

Liu Yijiu was not very clear about the small engine of this missile, so he could only study it slowly. And. This kind of engine not only has high requirements for materials, but also has higher requirements for processing technology.

Inside the base, until now, the CNC machine tool is still stuck on the four-axis machining center.

Liu Yijiu didn't use too much energy on it this time, the more the third area studied the four axes, the less difficult it will be to tackle the five axes in the future. That's the importance of the foundation.

What's more, the numerical control system is also very important. This in turn involves the computer that Cao Zhijiang studied.

Computers, on the other hand, involve chips......

As soon as he thought of this, Liu Yijiu's head was big.

That's why he needs to get those geniuses into his base.

"We are now at the experimental stage, and we should use this weapon module. The front of the plane is equipped with a 12.7 mm four-barreled machine gun of the North Industries Group, and rocket launchers are added on both sides of the helicopter, and if you add anti-aircraft missiles used to hit local helicopters and anti-armor missiles to hit enemy armored units...... Liao Zhuojing, who has not spoken, put forward his idea.

Straight-91, from the beginning. It was developed to support armored forces in operations.

And, of course, support for the Army. Provide fire cover and troop delivery for the army. And even more importantly, for special operations!

"......" Liu Yijiu didn't expect that Liao Zhuojing had already put forward his idea of a helicopter gunship.

This is the final form of the helicopter gunship he envisioned!

It's just that the details are definitely very different.

"Isn't that too much equipment? It is completely possible to change combat units according to different tasks......" Zhan Liko said with a frown.

"If our chicken rib missiles are used, there will be no problem at all, air defense and anti-armor will be taken into account. Rockets were used to slaughter dense infantry and hit armored clusters, not to mention machine guns in front. Qin Yuan didn't expect that there would be someone in the designer team who supported him.

"Yes, that's how it should be, and. We also have to equip the helicopter with decoy bombs, our anti-aircraft missiles and anti-armor missiles are mainly infrared-guided, and the helicopter is in the air, and the speed cannot be too high, so it must be equipped with decoy bombs...... "Zhan Liko continued to propose.

"What if you encounter an enemy bazooka? Also, if they also have an anti-materiel sniper rifle like the S75 and it is equipped with special bullets...... "Liu Yijiu didn't expect that these guys would even come up with decoy bullets.

He was tempted to ask again, what should happen if the enemy dropped a graphite bomb?

In the end, I still didn't ask.

If you really let them defend, it will be against the sky!

"Isn't that easy? Just like our Longweiyi, add a layer of metal grid to the helicopter to the vest...... "Wang Yueshan doesn't understand technology, and he thinks that the metal grid used by Longwei tanks to defend against anti-tank rockets is very good.

After the anti-tank rockets produced by Liu Yijiu by the North Industries Group and the Jiangbei Machinery Factory and showed themselves on the battlefield between Iran and Iraq, the Longwei 1 began to consider anti-rocket attacks.

With an offensive spear, it is necessary to have a shield that can defend against it.

If the enemy has something that can be defended, he will continue to upgrade the spear, so as to continue the cycle, so that the national defense science and technology system can continue to develop in this cycle of using his own spear and attacking his own shield.

"......" to install a grid for a helicopter?

Liu Yijiu felt messy. (To be continued.) )
