Doomsday Bunker Upgrade

Helicopter air filter is already a kind of black technology in itself.

After all, before this, no aircraft in the world would install an air filter on its own intake duct, which would really affect the intake.

However, Chen Xin, relying on the powerful system upgrade function, came up with an air filter that can be installed on the helicopter, so that the helicopter can also fly into the sky with the air filter installed.

"Will the power performance of the aircraft be affected after the air filter is installed?" Chen Xin put the two air filters removed from the Z-20 on the table, disassembled them, and pointed to the pilot next to him. asked.

"There is a certain influence. The intake air is indeed attenuated to a certain extent than before, but overall it can still meet the needs of flight, but the power of the engine is lower than before, and the load needs to be adjusted." The pilot Xiang Chen Xin reported the situation, and also informed Chen Xin about the changes in the performance parameters of the aircraft after the air filter was installed.

After listening to the pilot's introduction, Chen Xin nodded clearly: "It seems that the installation of an air filter still has a great impact on the intake air of the engine. Although it is not impossible to fly, it also has a great impact on the engine power. Without moving the engine, we can only continue to improve the air filter or enlarge the intake duct."

"If you enlarge the intake duct, will it affect the structure of the aircraft?" The pilot is naturally knowledgeable. Hearing Chen Xin say that the air duct needs to be improved, he is a little worried that this will damage the aerodynamic layout of the aircraft.

"It may have a certain impact, but it can be adjusted and it won't get in the way." Chen Xin didn't care about this, and it seemed to be an understatement.

Enlarging the intake duct does not affect the aerodynamic layout of the aircraft. This will be a big project for normal aircraft designers, and it may even be equivalent to redesigning the entire aircraft, but for Chen Xin, who holds the system, this is true It's nothing.

While studying the dismantled air filter, Chen Xin suddenly asked the pilot curiously: "Speaking of now, there is no satellite navigation, and the sky is so dark, how did you fly here?"

"There is a positioning instrument on the plane, and the orientation can still be determined, and with the altimeter, there is no danger of getting lost." The pilot said it easily, but only they knew the danger and difficulty of it.

The night flight itself is a difficult challenge. Before the disaster, there are many auxiliary conditions such as satellite positioning, tower guidance, air control, etc., it seems that night flight is not so difficult. Anyway, it is enough to fly according to the preset data. After all, there is no reference to fly high, everything depends on the various flight assistance systems on the plane, and even the autopilot can be turned on to let the pilot take a rest.

But without these things, flying becomes the dangerous and pilot-tested thing it used to be.

After the loss of modern auxiliary means, there is not much difference between the current aircraft flight and the World War II period, but the current aircraft is more advanced, and with computer assistance, compared to World War II pilots can only rely on compass and The watch calculates its own position, and now the pilot can read his precise position intuitively from various instruments on the plane.

But this does not reduce the danger of night flights, especially now that the visibility is low, and the hands are almost invisible, and there are hardly any reference objects on the ground. In addition, the helicopter is not flying at a high altitude, and it is likely to hit the mountain and cause damage. disaster.

Under such circumstances, it is truly remarkable that the pilot was able to fly the helicopter here and risk his life.

"Anyway, it's still very dangerous!" Chen Xin sighed, admiring these pilots a little more.

"How can a soldier be afraid of danger?" The pilot seemed to have realized this for a long time, and did not show any emotion: "Since he chose to be a pilot, he has already thought about the danger he is going to face."

Hearing what the pilot said, Chen Xin couldn't help but give him a deep look, but he didn't say anything, just turned his attention to the air filter in his hand, and then upgraded it with the function of the system.

"I made some adjustments to this air filter, which should improve the air intake. You can test it when you return, and let a professional technician check it after you go back. If you have any problems, you can always contact me. ." Chen Xin handed the upgraded air filter back to the pilot and helped them install it on the helicopter.

The pilot saluted Chen Xin and thanked him: "Thank you Comrade Chen Xin for your help, we will go first."

Perhaps it was the military's bad words. Although the pilot expressed his gratitude to Chen Xin, he did not say much thanks, but his thanks to Chen Xin was very sincere.

"It's a smooth journey." Chen Xin didn't mind this, smiled at the pilot, watched the other party get on the plane, restarted the plane, and set off a gust of wind.

He took a few steps back and retreated to a safe distance, watching the helicopter's propellers roll up the snow, and then gradually disappeared into the night sky.

"If the plane can resume flying, then life will be much better in the future." Looking at the flying helicopter, Chen Xin couldn't help but sigh.

"Helicopter may not be a problem, but is that kind of large jet okay? The air intake problem of large aircraft is much more serious than that of helicopter engines?" The political commissar on the side heard Chen Xin's sigh, and suddenly asked him curiously. asked.

Compared with helicopters with limited carrying capacity, fixed-wing aircraft is the real focus. After all, whether civil airliners, transport aircraft or military fighter jets are fixed-wing aircraft, and their engine intake is even greater, especially for large aircraft. , While several engines bring huge lift, the demand for air is also extremely amazing.

But if this problem can be solved and the big planes are back in the sky, the change that will bring about the current situation will be staggering.

"For large aircraft, you can first consider traditional propeller aircraft. Their engine air intake is not as exaggerated as that of jet aircraft. They can still fly with air filters installed, and if necessary, they can be changed to electric." Chen Xin said This is still considered, but for jet aircraft, he has no good solution: "As for jet engines... If the air quality has not been greatly improved, consider redesigning it, the air filter cannot meet the needs of flight. , a sound barrier that breaks through the air filter should be broken."

While not all jets can break supersonic speeds, it's clear that the military's supersonic fighter jets are the crux of the problem.

It's just that Chen Xin can't help it. Give him an aero engine and he may be able to transform an engine that can be used in today's environment, but this is not very necessary.

Because the dust in the air affects the flight only temporarily, as the dust gradually falls, when the air quality meets the flight requirements, those jets can naturally return to the sky. engine.

After all, if you can't fly, neither can others.
