In the military industry that year, the cloud bombs started to wash the ground for monkeys

The deputy chief engineer shouted this sentence with almost all his strength.

"Fly, straight 9!"

"Fly, straight 9!"

"Fly, straight 9!"

All the members of the Zhi 9 team yelled loudly almost in unison.

Lu Xuan looked at the youngest researchers who were in their forties.

I saw tears shining brightly on the faces of each of them.

Seeing this situation, Lu Xuan also choked up.

The research and development of Zhi 9 is not easy.

Huang Haiqing suppressed the excitement in his heart, and slowly pulled up the joystick.

The Zhi 9, which was hovering originally, began to fly towards the sky quickly.

"Old Huang, slowly raise the pitch to keep the helicopter flying smoothly..."

"Slowly increase the engine output power, don't overload the engine and stop it..."

Holding the walkie-talkie, Yu Jianmin told Huang Haiqing in the helicopter slowly.

"Boss Yu."

"Flying is normal!"

"The control system is normal!"

Huang Haiqing's voice came from the walkie-talkie.

Everyone present clenched their fists.

"I have confidence in our design!"

"I have the same confidence in your operation!"

Yu Jianmin flicked the tears from the corners of his eyes, he knew that the first flight was successful.

But his request was not just to fly, but also to do some performance testing.

Without the addition of a weapon system, the Z-9 has an empty weight of 8200 kilograms, which is two tons heavier than the Black Hawk.

This is because a lot of lighter titanium alloys are used to make the empty weight so light.

Straight 9 continued to fly high and soon turned into a small black dot.

Straight 9 quickly reached an altitude of 6000 meters.

"Smooth flight!"

"There is no abnormality!"

Huang Haiqing's voice came again from the intercom.

Hearing this voice, everyone immediately cheered.

"Success."

"The first flight was successful!"

Next, the helicopter made more than ten kinds of flying maneuvers in the air.

Diving at an oblique angle, ascending at an elevated angle, hovering in the air, and rapidly landing...

Under this series of difficult movements.

Equipment monitoring the flight was functioning normally.

0 · · Flowers · ·

It's just that no one has checked the data.

They all held binoculars and looked at Zhi 9 soaring in the sky.

The stable flying posture and the perfect action test made everyone shed tears of excitement again.

The first flight was not only a success.

Various air-flight tests were also completed.

Everything is so perfect, so smooth.

Straight 9 is like an eagle soaring in the sky, showing its style.

Two hours later, Z-9 successfully completed various performance tests and slowly landed on the airport.

When Huang Haiqing and the young co-pilot got off the helicopter, the ground crew immediately surrounded them.

They lifted the two pilots and threw them into the air...

Looking at this picture, Yu Jianmin raised his head slightly.

Try not to let the cloudy old tears flow.

"Congratulations, Mr. Yu!"

After an unknown amount of time, Lu Xuan's voice rang in Yu Jianmin's ears.

Only then did Yu Jianmin recover from his excitement, he looked at Lu Xuan's outstretched hand and held it tightly.

Lu Xuan clearly felt that the old man's palms were wet with sweat, and his trembling hands showed how excited he was now.

"Director Lu, Z-9 is tentatively designated as a medium-sized helicopter, with twin rotors and propellers, 21.85 meters long, 5.98 meters high, and 19.88 meters in rotor diameter..."

"Two domestic turboshaft 4 engines are equipped with a single power of 1540KW, a thrust ratio of 0.821, an empty weight of 8200 kg, and a maximum take-off weight of 19800KG..."

"With two standard external fuel tanks, the flight distance can reach 1880 kilometers, the combat radius is 488 kilometers, the climb rate is 5.9 meters per second, the practical ceiling is 6189 meters, and the maximum ceiling is 6521 meters..."

"The load is 10120 kg, the maximum flight weight is 12356KG, the maximum flight speed is 329 kilometers per hour, and the cruising speed is 288 kilometers per hour..."

Yu Jianmin took the first flight test report and introduced it to Lu Xuan seriously.

"The above performance parameters, we compared with the black eagle of Yingjiang, the length of the black eagle is 19.76 meters..."

Yu Jianmin spoke out the Black Hawk data he was familiar with, and made an intuitive comparison with Zhi 9.

In the end, he said solemnly: "Judging from the current data."

"No matter which aspect is compared, our straight 9 is better than the Black Hawk."

"Of course we still need to conduct multiple test flights to complete the comprehensive test of Z-9."

After listening to Yu Jianmin's introduction and comparison, Lu Xuan felt extremely relieved, and was very satisfied with Zhi 9...inch.

071 Create the most powerful Z-9 gunship

The maiden flight was a complete success.

And after various tests.

Verify that there are no problems with any of the components.

The rest is to continue the test flight, and it is a high-density test flight.

Continuously load various weapon systems and conduct various tests according to different requirements.

After the test is completed, the limit test is carried out, including the helicopter's ceiling, climb performance, hovering height, etc.

"The production of the remaining three prototypes can be speeded up. We must consider the weapon external holding system, as well as the design of various weapon magazines, weapon design..."

"The multifunctional use of the Z-9 must also be strengthened. Modes such as armed transport, individual troop transport, and armed helicopters must be considered, so that the helicopter can have more functions."

After the successful first flight, Lu Xuan summoned the Zhi-9 team, 618 weapon designer and other experts, and issued instructions.

The Z-9 "[-]" cannot be used only as a general-purpose helicopter, it must be multi-purpose.

"Weapon system, we no longer design and develop it alone, but cooperate with domestic brothers. Of course, their weapons and equipment need to meet our requirements..."

At the discussion meeting, Lu Xuan put forward his design opinions on the weapon mounting platform and weapon system.

"Director Xiao Lu, can the Red Arrow anti-tank rocket launcher and Black Arrow 2 anti-aircraft rocket launcher in our base be used on them?" Yang Changgen immediately put forward his opinion.

Although multi-barreled machine guns, aerial cannons and the like are provided to brother units.

The weapons that have been formed in the base can be used with only a little modification, and their performance is more advanced.

"Director Yang, if you want to transform our rocket launcher into a missile, you can just say so. As for finding such a reason?" Lu Xuan laughed.

Although Lu Xuan is the top leader of the 618 base, he doesn't want to be alone.

Sometimes, it may be better to get everyone involved.

For example, he didn't participate in the R&D and design of Zhi 9, didn't he come up with it?

Yang Changgen also laughed: "I just want our rockets to have a larger production volume, so that the cost can be effectively controlled."

For Yang Changgen, Lu Xuan has long been optimistic about his management ability.

The reform and opening up is about to be carried out. If Yang Changgen goes to sea, he will definitely become a rich man.

Wang Mingyi said: "We have sufficient rocket engine technology, solid fuel research has also achieved results, and computer technology and guidance technology are even stronger than those of foreign countries."

"It is not a big problem to transform the Red Arrow anti-tank rocket launcher into an air-to-ground anti-tank missile, and it is not difficult to transform the Black Arrow 2 anti-aircraft rocket launcher into an air-to-air missile."

Both types of rocket launchers are battle-tested.

Experts from the Rocket Artillery Research Office have already made many improvements to its existing defects.

There is no problem in transforming it into air-to-ground or air-to-air missiles.

Lu Xuan nodded and said, "In terms of the design and development of anti-tank missiles and air-to-air missiles mounted on the helicopter, Director Wang and everyone will have to work hard."

"It is worth noting that the armor-piercing capability of the Red Arrow anti-tank rocket launcher needs to be strengthened. Currently, it is no problem to fight T72, but it is still difficult to fight T64, M1 and Leopard 2."

"The range and speed of the Black Arrow 2 anti-aircraft rocket are not far enough, and the speed must reach Mach 2 or higher. This is not only related to the design of the aerodynamic layout, but also related to the rocket engine technology."

For the small missiles on the helicopter, Lu Xuan has no interest in participating.

After all, the rocket launcher research and development department has mature technical reserves, so there is no need to do everything by yourself.

He still concentrates on the anti-ship missiles mounted on fighter jets.

Prepare for the upcoming John Bull vs. Argan War.

"I suggest installing a 9mm four-barrel machine gun from the North Industries Group in front of the Z-12.7, and adding rocket launchers on both sides of the helicopter..." A weapon designer made a suggestion.

The research and development of Zhi 9 was originally used to support armored forces in combat.

Provides fire support to ground forces, troop transport, and for special operations.

"Director Xiao Lu, I think our Z-9 can also be used in the navy's anti-submarine equipment," another weapon designer said.

Lu Xuan frowned slightly. The Rabbit's navy seems to have no warships that can stop Zhi 9.

"That's the next thing. Let's get a thorough understanding of Zhi-9's technology first, and then design an anti-submarine helicopter after we get familiar with it."

"After our large warship is launched, it will be enough to add an anti-submarine system to the Z-9. The Z-9 is a basic platform."

anti-submarine.

Let the Rabbit Navy worry.

It also made Lu Xuan feel the most painful.

Even the 053 ship has not been completely done yet 0 ..

Even the 052 ship seems to be still in the drawing stage so far.

"I think we have to equip Z-9 with decoy bombs. The speed of the helicopter is not fast in the air. In order to enhance the survivability of the battlefield, we must equip it with decoy bombs." Another weapon designer suggested.

Lu Xuan didn't expect that these guys even came up with bait bombs.

At present, decoy bombs are only used on fighter jets, and the technology is not yet mature.

"What if you encounter an enemy rocket launcher or a large-caliber anti-material sniper rifle?" Someone expressed concern.

"It's not easy, we just add a vest made of metal grids to the helicopter." Someone immediately said whimsically.

At present, tanks with metal grids have indeed appeared in the world to defend against rocket launchers.
