Super Weapon Swap System

The silvery white fighter stands on the runway. Its natural and unrestrained shape makes people seem to have a desire to conquer it.

The small three-point landing gear is different from the previous fighters in the Han Dynasty. At this time, Chen Rui walked towards the fighter with his flying helmet.

Now it's the test flight stage, so the appearance of the fighter is still the same as the original aluminum alloy skin without painting, but the rivets can't be seen.

The technology of 1132 factory is constantly innovating, and the latest countersunk head rivets are adopted, so the hemispherical round head of rivets can no longer be seen, which can not only look good, but also reduce air resistance.

Yes, even to reduce air resistance, such a small amount of resistance should also be reduced.

Chen Rui climbed up the gangway and sat in the cockpit. He could see that a large group of people were watching not far away

As the chief engineer of the project, Mr. Song's eyes are full of expectation.

After closing the hatch cover, Chen Rui began to skillfully turn the switches.

With the help of the ground power vehicle, the unique roar of the turbine engine came from the tail. Chen Rui looked at the instrument in front of him and said, "the ghost reported that the instrument display was normal, and requested a medium speed taxi experiment."

When the fighter is taxiing, the first is low speed. It was done yesterday. Today is medium speed. If it goes well today, it will enter the high-speed taxiing stage tomorrow.

Since the eagle kingdom came back, Chen Rui's nickname ghost has spread.

In the radio calls of the Han air force, there are few nickname calls, all of which directly call the digital number. In order to strengthen the digital number, the pilots of the Han country almost forgot their names from the day they entered the army. They call the digital number from each other, whether it's training, eating or sports.

Chen Rui finally made a special use of his nickname. At the same time, he was very satisfied with the nickname.

An echo came from the radio: "start the experiment, pay attention to the direction."

"I see." Chen Rui answered and released the brake.

Although the engine at the tail is only running at low speed and can output enough power, Chen Rui focuses on the instrument below with the residual light from the corner of his eyes. At the same time, his eyes are mainly outside.

The view of the pilot's cockpit is not good. It is blocked by the fuselage. Judging from both sides is often easier than judging from the middle.

The speed soon reached 60 km / h, which is the minimum speed of medium speed taxiing. From 60 to 100, it will be successful after being stable for a period of time.

Just then, suddenly, Chen Rui felt something wrong.

"Report, the fighter is offset to the right!"

With Chen Rui's words, the following people also saw that the fighter plane was facing the center line of the runway when it began to slide, but now, with the progress of the slide, it can be found that the fighter plane is running to the right for no reason!

"Taxi stop!" said old song.

Old song frowned. A large group of people watched the Raptor stop and rush towards the other side.

The test flight hasn't officially started yet. It's just a run, and the problem has come out.

Medium speed taxiing experiment mainly depends on the deviation correction ability of the aircraft.

Simply put, it means putting the plane on the runway and taxiing forward only by engine thrust. If the plane deviates to one side and can't walk in a straight line, it indicates that there is a problem with the plane.

There are many factors leading to deviation, which may be aerodynamic asymmetry caused by aircraft shape asymmetry; There may also be a problem with the landing gear - including the installation position of the landing gear and braking, which may cause the aircraft to deviate.

Now, this aircraft is a imitation. It is said that the prototype has solved this problem, but now, there is still such a situation. What is the reason?

Old song also trotted along. When he ran next to the plane, Chen Rui had turned off the engine and was waiting for the ground crew to move the ladder down.

Old song ran over and the first thing to check was the brake.

The aerodynamic shape of the aircraft should be no problem. The biggest reason may be the brake.

Sure enough, when old song put his hand on the brake, he almost cried out. It was so hot!

"There's a problem with the brake." old song said, "the braking strength on both sides is not uniform. Adjust the brake immediately!"

Any small problem may lead to the performance difference between the new fighter and the prototype.

In a word, the domestic basic industry still fails to pass. Based on the domestic basic industry, what we get is the current result.

The problem is on the brake disc.

In later generations, some drivers will immediately complain when they see rust on their brake discs. What kind of broken car is this? Rusty!

Yes, he was quite dissatisfied when he saw that the brake disc was rusty. At this time, someone would come up with an idea: "if you want to avoid rust, it's easy to say. Just put some oil on it and lubricate it?"

Of course, it's a joke. If you really put oil on it, it's definitely out of your mind.

Because most cars usually use metal based brake discs, which is an iron or an iron that will rub with the brake pads at any time. The surface is very bright. When there is water, rust is inevitable.

If you want to find something that doesn't rust, there are only high-performance cars with ceramic brake discs.

Of course, ceramic brake discs are not the most advanced. The most advanced is carbon carbon based brake discs.

Metal based brake pads have low friction coefficient and poor high temperature resistance, so they are not the best choice. Another important factor is its weight.

The weight of the brake pads has little effect on the car, but it is very different for the plane. For an aircraft flying in the sky, the loss of one kilogram of weight has a significant impact on the overall carrying capacity and endurance time of the aircraft.

Therefore, the brake pads on advanced aircraft are now replaced by carbon carbon based brake pads. Because carbon carbon based brake pads have good high temperature resistance, high friction coefficient and high temperature corrosion resistance, the most important thing is that carbon carbon based brake system can reduce weight by more than 40% compared with metal based brake system, and its service life is 5-7 times that of metal based brake system!

In history, Han pilots watched the flight performance of mirage 2000. When the other party flew down, they found that they stopped directly. Everyone hurried to look and touch the brake pads. When they found that the other party's brake pads were not hot, everyone was shocked, which was beyond their understanding!

However, this thing can't be made if you want to. The carbon based braking system in Han country can't make a breakthrough until more than ten years later.

Therefore, although the prototype is equipped with carbon based brakes, their current imitation still uses the original metal brakes. When adjusting, the strength is different, which leads to the deviation of the aircraft.
