Chapter 386: Problem with airplane

Text Chapter 386 The Problem of Aircraft
The installation of air filters in helicopters is already a black technology in itself.
After all, before this, no aircraft in the world would install an air filter on its intake duct, which would really affect the intake too much.
However, Chen Xin relied on the powerful upgrade function of the system to come up with an air filter that can be installed on a helicopter, so that the helicopter can fly into the sky with an air filter.
"After installing the air filter, will the power performance of the aircraft be affected?" Chen Xin placed the two air filters removed from the straight 20 on the table, disassembled them, and directed them to the pilot next to him. Asked.
"There is a certain impact. The air intake does have a certain attenuation than before, but on the whole 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 told Chen Xin reported the situation, and also told Chen Xin about the changes in aircraft performance parameters after the air filter was installed.
After listening to the pilot’s introduction, Chen Xin nodded clearly:
It seems that the addition of an air filter still has a great influence on the intake of the engine. Although it will not be impossible to fly, it also has a great influence on the engine power. Without moving the engine, you can only continue to improve the air filter or enlarge the intake duct."
"Enlarging the intake duct will affect the structure of the aircraft?" The pilots are naturally knowledgeable. Hearing Chen Xin said that the air duct should be improved, some were worried that this would destroy the aerodynamic layout of the aircraft.
"There may be a certain impact, but if you can adjust it, it won't get in the way." Chen Xin didn't care about it, and he seemed to understate it.
Enlarging the intake duct does not affect the aerodynamic layout of the aircraft. This would be a big project for a normal aircraft designer, and it is even equivalent to redesigning the entire aircraft, but for Chen Xin who holds the system, this is true. It's nothing.
While studying the air filter that was taken apart, Chen Xin suddenly asked the pilot curiously: "Speaking of which there is no satellite navigation now, and the sky is so dark, how did you fly here?"
"There are positioning instruments on the plane, and the position can still be determined. With an altimeter, there is no danger of getting lost." The pilot said very easily, but the danger and difficulty of this are only known to them.
The night flight of the aircraft itself is a very difficult challenge. Before the disaster, with satellite positioning, tower guidance, air control and many other auxiliary conditions, night flight does not seem so difficult. Anyway, just fly according to the preset data. After all, there is no reference to flying high, everything depends on the various flight assistance systems on the plane, and even autopilot can be used to let the pilot take a rest.
But after losing these things, flying becomes the kind of dangerous thing that tests the level of pilots in the past.
After the loss of modern aids, the current airplane flight is actually not much different from the World War II period, but the current airplanes are more advanced, and with computer assistance, compared to the second world war pilots can only rely on compass and The watch calculates its own position, and now pilots can intuitively read their precise position from various instruments on the plane.
But this does not reduce the danger of night flight, especially now that the visibility is almost invisible, there is almost no reference object on the ground, and the helicopter flying height is not high, it is likely to hit the mountain. disaster.
Under such circumstances, the pilots were able to fly here with a helicopter, indeed risking their lives, which is really remarkable.
"Anyway, it's still very dangerous!" Chen Xin sighed, admiring the pilots a little bit more.
"How can a soldier be afraid of danger?" The pilot seemed to be aware of this, and did not show any emotions: "Since I have chosen to be a pilot, I have already thought about the dangers I will face."
Hearing what the pilot said, Chen Xin couldn't help taking a deep look at him, but didn't say anything, but 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 the professional technicians see it when you return. If you have any questions, 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 bowed to Chen Xin and thanked him: "Thank you Comrade Chen Xin for your help, we will go ahead."
Perhaps it was the poor words of the soldiers. Although the pilot expressed his gratitude to Chen Xin, he did not say much, but his gratitude to Chen Xin was very sincere.
"Good trip." Chen Xin didn't mind this, smiled at the pilot, and watched the other party get on the plane, restarted the plane, and a gust of wind was set off.
Stepped back a few steps, retreated to a safe distance, and watched the helicopter's propeller roll up the snow, then gradually pulled up and disappeared into the night sky.
"If the plane can be resumed to fly, then the days will be much better." Looking at the flying helicopter, Chen Xin couldn't help but sigh.
"Helicopters may not be a big problem, but is that kind of large jet aircraft okay? The air intake problem of a large aviation engine is much more serious than that of a helicopter engine, right?" The political commissar on the side heard Chen Xin's sigh and suddenly asked him curiously. Asked.
Compared to helicopters with limited carrying capacity ~EbookFREE.me~ fixed-wing aircraft is the real focus. After all, whether it is a civil aviation airliner, a transport aircraft, or a military fighter jet, they are all fixed-wing aircraft, and their engine intake is even greater. Huge, especially 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 large aircraft can return to the sky, the changes brought about by the current situation will be amazing.

"For large airplanes, you can first consider traditional propeller airplanes. Their engine intake is not as exaggerated as jet engines. They can still fly with air filters, and they can be changed to electric if necessary." Chen Xin is right. This is still something to consider, but for jet aircraft, he does not have a good solution: "As for jet engines... if the air quality is not greatly improved, consider redesigning. Air filters cannot meet the needs of flight. , A sound barrier should break through the air filter."
Although not all jets can break through supersonic speed, it is clear that supersonic fighters in the military are the focus of the problem.
It's just that Chen Xin can't help. 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 jet aircraft can naturally return to the sky. There is no need to specifically redesign one to meet short-term needs. Models of engines.
After all, you can't fly, and others can't fly either.
