142nd Air Combat Zero (2)
During the design of the Zero fighter, there was a debate among military representatives at the Mitsubishi Corporation's New Fighter Performance Orientation Conference, with one faction holding that air combat capability mainly depends on turning combat performance, and range and speed must be sacrificed for combat performance.
On the other hand, the other faction believes that the fighting performance of the Japanese fighter is superior, enough to fight any fighter in the world, and the difference is speed, and the new fighter should focus on solving the problem of speed and range, and the combat performance can be sacrificed appropriately. At one point, two diametrically opposed ideas emerged at the meeting, and no one could convince anyone, so the meeting had to be adjourned.
Because these two requirements were too demanding, especially the conflicting requirements of endurance of more than 1,300 nautical miles in 8 hours and the maneuverability of the aircraft, Nakajima abandoned the bidding during the design stage, and Mitsubishi designed it alone.
On March 16, 1939, the first prototype was completed at the Mitsubishi Nagoya Plant. The new aircraft was delivered to the Army Training Airfield in Komugahara for flight testing. On April 1, 1939, the prototype was piloted by test pilot Shima Katsuzo and made its first successful flight, and the test flight results were very successful, with only minor problems with the wheel brakes, lubricating oil system, and slight vibrations during flight.
After the three-bladed constant speed propeller was replaced, the vibration disappeared. On September 14, 1939, the Japanese Navy approved the prototype, officially designated A6M1, and the second prototype was completed, and in October passed the company's internal test flight.
The Zero was an important milestone in Japanese aircraft design, as it achieved a number of firsts, such as the first fully enclosed retractable landing gear, electric thermal flight suits, large-caliber machine guns, constant-speed propellers, ultraduralumin load-bearing structures, large horizon cockpits, and large disposable fuel tanks.
A key factor in the success of the Zero fighter was that Sumitomo Metal Co., Ltd. of Japan synthesized a super aluminum alloy at that time, called 50 Arashi Metal in Japan, which was harder than steel, because with this metal Zero design used a very thin frame and dared to drill holes in it to reduce weight.
In addition, the size of the rivets is also very small, which greatly reduces the weight of the aircraft while ensuring the strength of the fighter, and without this aluminum alloy from Sumitomo Metal, the Zero would not have been produced at all. Because of the super hard aluminum alloy, the main truss of the aircraft has been innovated, which has good tensile strength, better fatigue strength, and extremely light body weight.
The Zero uses a 950-horsepower Nakajima "Rong" 12-star air-cooled engine, although it is not outstanding compared to the same period in Europe and the United States, but due to the light body, the empty weight (Type 21) is only 1680 kg, and the speed reaches 533 km/h.
The biggest source of the performance advantage of the Zero is its lightness, with very small wing load, which completely makes up for the lack of engine power and ensures a large range of 2,200 kilometers. At the same time, due to its lightness, the Zero also gained a very fast rate of climb: 900 meters per minute. It completely surpassed the European and American fighters such as F2A, F4F, P-40, and Spitfire of the same period, and its low-speed combat ability and turning radius were better than those of the European and American fighters of the same period, making it difficult for allied pilots to get a chance to fire from the back close to zero route.
As a result, the Zero's superior maneuvering capabilities often put the Zero at an advantage in early close-range air combat. The Zero has a very clean and beautiful aerodynamic shape for a fighter with an air-cooled engine, and has a fairly low drag, which is not only good for higher speeds with lower engine power, but also good for fuel saving.
The weather is very good, the sky is very blue, and Squadron Leader Zero Mu pilots this kind of first-class aircraft that is enough to surpass European and American countries, which can be said to be full of confidence and bullishness. He wanted to make meritorious contributions to the Japanese Imperial Army, and to eliminate all the Chinese air forces that dared to break ground at Nanyang Airport on the head of Tai Sui.
The Japanese military intelligence department said that although the Chinese army had a Nanyang airfield, there were no Chinese army planes, so the Japanese army did not care about it. Suddenly, intelligence came that a large number of Chinese planes had appeared at Nanyang airport, transporting troops and supplies.
The 3rd Flying Regiment was like a wolf meeting a little lamb, how could he let go of this little fresh meat, and Ling Mu also repeatedly asked for battle to get such a meritorious opportunity.
Ling Mu led his aviation squadron, just like the demonstration, first circled around the sky over Nanyang Airport. His nose also snorted, what does the Chinese Air Force have, there are no anti-aircraft guns, there are no anti-aircraft machine guns, and the only few broken planes do not know where to hide, and they can't fly at all.
As long as they dare to fly, I will dare to fight, and I will definitely beat the Chinese Air Force to the ground.
The line of sight is excellent, Squadron Leader Lingmu looked up at Nanyang Airport, except for the main runway, the apron, and then some dilapidated houses, there seems to be nothing on the empty Nanyang Airport. What about their planes, where did their planes go.
Squadron Leader Lingmu had no choice but to say to the first squad leader Sanxiao: "Squad Leader Sanxiao, go down and take a look at the situation, as long as there are clues from the Chinese Air Force and all of them are eliminated, they must be hidden in the ground, and they must be dug out." ”
The captain of the Sanxiao squad agreed, and shouted: "The first squad comes with me," and as soon as the fuselage flipped over, he turned down and slowly lowered the altitude.
The three Zeros behind him also followed his example, flipped their fuselages, turned down, followed him, and searched and moved forward unhurriedly.
5000 meters, 4000 meters, 3000 meters, 2500 meters, the ground has been seen more and more clearly, runways, aprons, houses, trees in the distance, there is no shadow.
Suddenly, just behind a pile of houses, a small rocket burst out of the back, followed by another, and another, and four in a row.
This is the Hongying-5 vehicle-mounted anti-aircraft missile.
The missiles are loaded on 4X4 launch vehicles, each equipped with two groups of four missiles, equipped with televisions, infrared alert and tracking systems.
The total weight of a single weapon system is 16.9 kg, the missile is 1.526 meters long, the diameter is 71 mm, the maximum range is 5000 meters, the minimum range is 500 meters, the maximum combat altitude is 4000 meters, the minimum combat height is 15 meters, the maximum oblique distance is 5000 meters, the minimum oblique distance is 500 meters, and the combat reaction time is 5-10 seconds.
No matter how fast the Zero fighter is, it is not as fast as the missile, and besides, the two aircraft are facing each other, and the faster the plane flies, the faster the time it will take to be hit.
Sanxiao was piloting the plane, slowly searching the ground, and suddenly saw a small rocket flying behind his buttocks, he knew that it was a big deal, and hurriedly shouted loudly while dodging the small rocket: "Enemy attack, enemy attack, quickly dodge, quickly dodge-"
At that time, the flight speed of the Zero aircraft was more than 100 meters per second, while the flight speed of the missile was 850 meters, and the distance between the two sides was about 2,500 meters, and there was still a few seconds of reaction time. To say that this three Xiao, it is really not simple, quickly open his head down, and then turn, that action is really chic and neat.
After completing this set of actions, Sanxiao has completed the rapid turn, and he is really not a model driver. When he was speeding up to escape, he looked back a little, no, this small rocket that was burning behind his butt was still chasing him.
Ouch, my mother, this little rocket that is blazing has eyes, it chases wherever it runs, and it will turn around!
Just when San Xiao was in doubt, the small rocket that was burning behind his ass had already hit his ass, and it was too late to take any action. The shell of the Zero aircraft is made of aluminum alloy, isn't it hard, and this small rocket drills into it vigorously, because the aluminum alloy also has defects, that is, it is mixed with a lot of magnesium (magnesium is a raw material for fireworks), which is easy to catch fire when heated.
The Zero was on fire at that time. Even if the missile caught fire, it was still drilling into it, the fuse was triggered, and there was a "boom-" sound, a big explosion, and the butt of the plane suddenly turned into nothing. The ass is gone, what kind of strength is the plane flying, and a fire engulfs Sanxiao in an instant.
San Xiao's brain is not dead yet, he still has to think: strange, what kind of weapon is this small rocket that is burning behind the buttocks? How could he still turn a corner? Why are you so unlucky? Is this the end of the unprecedented Zero?
I'm not reconciled, I won't be blind to death!
Before he died, he was still crying out in despair.
Sanxiao's flying skills are high, and the three pilots behind him are certainly not as good as him. There is a factor that Sanxiao's plane flies in front, which more or less blocks the view from behind, and second, it is a little dependent on Sanxiao.
Sanxiao's plane turned sharply, and the second plane was still a little confused, what does this mean by the squad leader, and the enemy attacked the enemy, the enemy attacked the head, why didn't I see it!
Just as he hesitated, the second Hongying-5 missile had an intimate kiss with it!
The shell of the Zero aircraft is hard, but the shell of the missile is harder, and here there is also a question of speed, who is faster, who is the protagonist. The missile got into the belly of the Zero plane at once, and the slippery and greasy missile shell slipped under the crotch of the pilot Xiao Si, and also touched his little brother for a moment.
"Oh, my mother, it's hot! It's hot! I haven't done anything bad, don't punish me like that! ”
Xiao Si was shouting that he was wronged, and he didn't deserve such punishment. But it was too late to shout, the fuse of the missile was triggered, but there was still a time lag from triggering to exploding, so Xiao Si had such a rich thought.
"Boom-" The earth sounded, Xiao Si only felt that the heavens and the earth were turning, and the end of the world had come.
From a distance, this Zero aircraft is a big gift, thanks to the Japanese engineers, for loading this plane with such good raw materials. At this time, the composition of magnesium showed its greatest charm, and the plane turned into countless fragments, each of which was burning.
It's a pity that it's daytime, and if it's night, it must be colorful and beautiful.
The third plane, the fourth plane, of course, could not escape the fate of destruction, and all of them died with the Hongying-5 missiles, turning into beautiful butterflies on fire in the sky.
