Although the long-sky sword refers to the system of cooperation between fighter jets and missiles, without this thing, fighter jets have no combat capability at all.

Air-to-air missiles are mainly used to guard the blue sky of the Republic and fight for air supremacy.

"Sharp sword..." Du Zhongkun muttered the name.

"After the final assembly is completed, test the effect from the launch track. Don't let the missile be ready. There is a problem when launching..." Seeing that the shape in front of you has been formed, only the last slender air-to-air missile is left with the painting process. , Liu Yijiu said to Du Zhongkun.

He clearly remembered that when the Republic was imitating a new type of air-to-air missile (it seems to be imitating r-77), when the target was shooting, the missile could not successfully escape from the launch rail when it was fired. A large number of people were terribly frightened. In the final inspection, it was discovered that the missile was not problematic, but it did not match the launch track on the launcher...

Liu Yijiu could not let such a thing appear in the Ninth Hospital.

"This shouldn't be a problem, right? We use supercomputers to simulate various situations..." Du Zhongkun's mouth was open and he could lay an egg.

The current r-77, but the top aerospace technology team has invested a lot of energy, developed on the basis of the Soviets, and there will be no such mistakes.

"Whether there will be any problems, just experiment. You can't just stop experimenting because you think it's simple. I don't want any problems. I also hope that my view is wrong. It's just ours. Missiles are very different from other missile launches..." Liu Yijiu said silently.

He could only tell Du Zhongkun secretly, instead of speaking out in front of other people."Be careful. We only have less than three months. If there is a problem with the test on the eve of the shooting, it will affect our final shooting. The gift to the Republic’s birthday will have to be ruined, and the Iranian order There will also be problems."

Du Zhongkun expressed his understanding that Liu Yijiu did not emphasize too much.

The imitation f-14 has basically the same appearance as the American f-14, except that the avionics system, radar, and fire control system inside have undergone great changes. Naturally, the loading of the weapon system has to be cautious. Before, just The hanging points on the belly of the fighter plane and under the wings are hung with the same shape and weight as these designed missiles to demonstrate the influence of the weapon system on the fighter's performance during the flight.

What Zhu Hodao and others hope more is to replace them with real missiles for some tests.

After all, there is a big difference between the model and the missile. If the design is not completely finalized, it is likely that there will be many differences in the interior of the missile.

The center of gravity even shifted.

When flying an opponent's fighter in the air, any weight problem can affect the attitude during the flight.

The first batch of six Longkong Sword-11s was quickly assembled and transported directly to Chengdu Phoenix Mountain Airport at night with Zhi-91.After completing some basic tests, the fighters were transported to Phoenix Mountain Airport for more tests. The 132 factory airport is not suitable for long-term fighter tests.

"Finally here! As long as you hang up all this stuff, the panda will be able to carry out the test flight after the weapon system is loaded..." Zhu Houdao and others have been waiting, seeing the slender air-to-air missile, this is domestic The first medium-range air-to-air missile!

"Hang up the Changkong Lijian-01 too, or mount a part first." Liu Yijiu didn't want them to affect the flight test because of the progress of the chart.

Zhu Houdao nodded. Now that July has entered, the weather in Rongcheng is very hot, and the air visibility is very good, and it is suitable for the test flight at any time.

"Don't worry, we have to test the coordination relationship between the missile and the launch track on the ground..." Du Zhongkun stopped. "After all, the launch method of our missile is very different from the previous Thunderbolt series."

Seeing other people staring at him unexpectedly, Du Zhongkun said calmly.

"A small amount of fuel was added, except for model missiles without a warhead."

The only person who was still calm was Liu Yijiu.

The newly designed launch rail is very different from the Thunderbolt series.

"According to our new design, it is very different from the Soviet launch method. It is mounted backwards on the bracket and launch rail, and a booster is installed at the back. This just allows the missile to be separated from the launcher. Facing forward The booster nozzle is covered by a pneumatic fairing, which is blown off when the booster is ignited. The booster moves the missile away from the launcher and overcomes most of the negative velocity caused by the high-speed flight of the missile on the aircraft. …Then the main engine is ignited and the connected booster is disconnected. The increase in thrust enables the missile to completely overcome the negative velocity of the missile when it is launched 30 meters behind the aircraft. The missile seeker that locks the target before launch continues to track the target, With the help of the gas rudder deflector during the boost period, the accelerated missile body can make a turn of ±180° to make the missile fly towards the target..."

Du Zhongkun explained the new missile launch principle.

Whether it is the Changkongjian-01 for short-range air-to-air missiles, or the Changkongjian-11 for medium-range air-to-air missiles, this principle is adopted to enable the missile to have a larger range of attack angles.All of this is achieved by supporting the advanced electronic system of the missile.

"You didn't experiment before?"

"To make the missile generate negative speed, it is only in flight, although it is also possible in high-speed wind tunnels, but our wind tunnels are always overloaded..." Du Zhongkun shook his head and sighed. .

Large rockets, all kinds of missiles, and all kinds of aircraft have to carry out very long blowing experiments in the wind tunnel to obtain more rigorous data and make the design more reasonable.

If problems are discovered and modified during design, the overall design cost will be reduced a lot. Otherwise, if the modification is made during mass production, more funds will be wasted.

Du Zhongkun did not say anything in this situation.

It was decided to start loading the weapon system overnight that night, and test the model the next day. If it succeeds, the missile will be tested in the air several times as soon as possible.

On the contrary, the missile sample can only be launched when it hits the target.

The maximum vertical axis angle of the missile above the fighter must be tested.The off-axis angle is too small, which will limit the missile's combat range.

In the morning of the next day, the missile model and launch rail were already installed on the pylon.

"Check the status of the weapon system carefully, just say if you can, and follow the order to launch..." Du Zhongkun said to Liu Yufei calmly before Liu Yu flew on the plane.

Tested on the ground platform, but it does not mean that the missile can be launched easily on the fighter plane.

Launching when the fighter is not taking off does not mean that it can be launched easily in the air.

The test of the weapon system of a fighter plane is not only to test the flight capability of the fighter plane, but also to test the coordination of the entire weapon system and the fire control system.

As the captain of the 132 factory flight test brigade, Liu Yufei is top-notch in both flight skills and flight test experience.

He also knows the importance of the next test. Whether this fighter is successfully developed depends on the weapon system and the avionics system.

The radar system has met the design requirements. After all, in the previous flight test, the civil aircraft in Chengdu was the best target.

After getting on the plane, I sat in the cockpit of the plane that had been seated hundreds of times again, activated the switches according to the process, and checked the various systems. After checking the status of the fighter, he reported to the chief engineer through the headset: "The fighter is in good condition. Equipped..."

"The missile launch countdown, 10, 9... 1, 0!" Without too much nonsense, I started the experiment directly.

The guidance system of the missile is restricted, the warhead is cancelled, and there is no fuel. The missile can be separated from the fighter plane, and the engine does not need to be ignited.On the runway of the airport, the fighter did not ignite, and the various systems inside had begun to work under the drive of backup power.

The moment Liu Yufei heard 0, he was already ready, and he pressed his thumb on the missile launch button on the top of the joystick.

"Boom!" A slender missile model weighing more than one hundred kilograms, nearly four meters long, and only about 300 mm in diameter on the weapon hanging point on the left wing of the fighter plane near the root. The tail is connected to the back of the launch rail. The booster starts to ignite under the power of the aircraft.

Many technicians standing less than five meters away, their hearts trembled when they heard this voice.

This is the most basic and crucial part of weapon system testing!

"We must get away and succeed!" Du Zhongkun and others were praying secretly in their hearts.

However, the fact is not as they imagined. The fairing on the booster behind the missile was blown off, and with a bang, it fell down towards the back until the fairing hits the hard floor and the sound came in. In the ears of everyone, they did not see the missile model that started to tremble when the booster was working, leaving the launcher!

Even with the huge thrust generated by the booster, even the fuselage of the fighter jet began to tremble.

"Close!" Seeing this, Zhu Houda was afraid that too much thrust of the booster would affect the body structure, so he hurriedly issued an order to you.

Du Zhongkun had no idea that this would be the result.

Liu Yijiu may have discovered a design problem before.

"This can't be turned off. The booster is originally a disposable consumable. In the process of detachment in the air, after the missile is taken off the launch orbit, the fuel jet injected backwards can be blown off when the rocket is ignited..."

For a while, the atmosphere on the scene became a bit tense.

[515 is coming soon, I hope to continue to hit the 515 red envelopes list. By May 15th, the red envelope rain can give back to readers and add promotional works.One piece is also love, it must be better!
