Whether Lin Fei took out the plane or not depends on how strong the performance of the Japanese plane is.

Lin Fei carefully read the report sent back by Lin Gecheng, and found that the Japanese aircraft were still using double-layer wings, this wing form was used a lot in the early planes of Lin Fei's era, and in modern times, except for some small aircraft, there are no planes that use this wing form anymore.

As long as a type of aircraft uses double wings, it means that it will not be too fast, because there are long pillars between the two wing surfaces, that is, the poles erected between the two wings that Lin Gecheng saw, which will provide great resistance when the aircraft is flying, causing the aircraft to fly at a slow speed.

In fact, the reason why the aircraft adopts a double-wing layout is also because the flight speed of the aircraft is not high, which requires two wings to generate lift.

In Lin Fei's era, there had never been an airplane using this machine gun arrangement, because this would destroy the airflow field of the wing, resulting in a great reduction in the lift of the aircraft.

Lin Fei frowned and thought for a while, thinking that these Japanese planes should be Japan's early test models, so the machine guns were arranged on the lower wings, and the Japanese army's subsequent models would definitely be improved.

Lin Fei was thinking about it, when Xiyun came in from outside and said, "Husband, the dark sword has sent information from Japan. "The dark sword is a spy that Lin Fei planted in Japan, when Lin Fei recovered Taiwan, the dark sword played a great role, and passed on key information to Lin Fei many times, and then Japan was defeated from Taiwan, and the dark sword followed the Japanese army back to Japan, and lurked in Japan to collect intelligence for Lin Fei.

Darksword's cover identity in Japan is a spy who collects intelligence about China, but in the First Nanyang World War and the Second Nanyang World War, Darksword did not provide Japan with any valuable information, which made Japan gradually alienate Darksword, and Darksword could access less and less information.

Lin Fei originally planned to let Darksword return to China and take up other positions, but Darksword did not agree, he insisted on staying in Japan, hoping to find an opportunity to obtain information.

Lin Fei hurriedly took over the information from Xiyun's hands, it turned out that this was a list of Japanese imported materials, the import object was the United States, and the imported items were the HT-5 gasoline engine produced by Klein Company, which was a six-cylinder in-line water-cooled engine with a rated power of 40 kilowatts, and the number of imports was 100 units.

This type of engine has a very low weight, so it is particularly suitable for use in aircraft, the power of forty kilowatts does not seem to be large, but it is more than enough to drive the aircraft, you must know that the Wright brothers first tested the aircraft in the Lin Fei era, and the engine power used was less than nine kilowatts.

Darksaber said in the intelligence that this list of imported materials was top secret, and it was said to be for a mysterious project, and the project code and content were unknown.

Lin Fei believes that this type of engine imported from Japan is the power equipment of that type of aircraft, and if this is the case, the power of the Japanese aircraft engine is only 40 kilowatts, while Lin Fei's plane, using the improved Diesel engine, has reached 80 kilowatts.

If the power of the Japanese aircraft engine is only forty kilowatts, it means that its carrying capacity is not large, the carrying capacity is not large, and the firepower is naturally not strong.

Lin Fei decided not to use the plane.

Lin Fei not only did not use airplanes, but also severely undermined Japan's confidence in developing airplanes.

Lin Fei sent a telegram to Lin Gecheng, in which Lin Fei gave instructions that the Japanese planes were not fast, the carrying capacity was not large, and the firepower was not strong, so they might not be the nemesis of the Monkey King's airship, and your department should build and control the fighters, carry forward the advantages of the Monkey King's airship in terms of strong firepower and large bomb load, and strive to annihilate the Japanese planes.

Lin Gecheng was very disappointed when he received Lin Fei's instructions, but he still made a plan to annihilate the Japanese plane.

At 8 o'clock in the morning of 16 August, eight Monkey King airships took off to look for Russian artillery positions, and in the rear of the Monkey King airship, four hot air balloons monitored the battlefield and looked for Russian anti-aircraft guns.

Perhaps the Russian army was protected by Japanese aircraft, and after the Monkey King airship broke through into the Russian position, none of the Russian anti-aircraft guns opened fire, and the Monkey King airship easily approached the artillery position.

At this moment, Yuki Haysawa led 32 Japanese planes to fly to the battlefield, and in the previous sortie, the Japanese planes did not fire a single shot, and today there is finally a big battle.

Yuki Uizawa had never used airplanes to fight before, so he didn't know how to optimize the air combat formation, thirty-two Japanese planes, lined up in two horizontal formations, looking at it from the air, it was two long lines, and the Monkey King airship quickly discovered the Japanese planes.

Although the speed of the Japanese aircraft is not fast, it is still much faster than the Monkey King's airship, and the Japanese planes can fight if they want to hit the Monkey King's airship, and they can run if they don't want to hit the Monkey King's airship, so in this competition, the Monkey King airship is at an absolute disadvantage.

However, the Monkey King airship has its own advantages, that is, firepower, the Japanese aircraft only have two machine guns, and the Monkey King airship has been able to load four Grimm guns before switching to helium, each with a thousand ammunition, after switching to helium, the number of Grimm guns carried has doubled, reaching a terrifying eight.

Despite the firepower advantage, Lin Gecheng still has a little bit of peace of mind, that is, the top of the Monkey King airship is an airbag with a length of 156 meters and a diameter of 19 meters, forming a huge shooting blind spot, as long as the Japanese aircraft drill into this shooting blind spot, the Monkey King airship will no longer be able to hit it.

So Lin Gecheng ordered the operator to be ready to raise the Monkey King airship at any time, Lin Fei gave Lin Gecheng instructions, the performance of the Japanese aircraft engine is limited, and the ceiling may not be too high, so the Monkey King airship can raise the altitude and condescendingly attack the Japanese aircraft.

The two black lines formed by thirty-two Japanese planes approached the Monkey King airship in the blink of an eye, and without Lin Gecheng's order, all the gunners opened fire, and the bright tracer shells drew a dazzling long line in the air, shooting directly at the Japanese planes.

There was no radio on the Japanese planes, so as soon as the fight started, the Japanese planes had to fight on their own, and it was precisely because of the lack of communication and exchange that an accident occurred.

A Japanese plane saw that the Monkey King airship opened fire, and hurriedly turned the rudder to the right, hoping to avoid the shells, but the Japanese planes lined up in a linear formation, and the rudder directly collided with another Japanese plane, and the two planes fell down with smoke together.

The Japanese planes lost two planes before the battle began, which made the Japanese pilots distressed and angry, and they dodged the shells of the Monkey King airship and fired bullets at the Monkey King airship.

There were no aerial shooting sights on the Japanese planes, so the Japanese pilots all hit them by feeling, and the biggest thing on the Monkey King airship was the airbag, so most of the bullets of the Japanese plane hit the air bag, and the filling gas of the Monkey King airbag was helium, which would not explode at all, and the bullets of the Japanese plane had no effect.

Some bullets hit the pod, because the Monkey King's airship was laid with aluminum alloy armor outside the pod, and the bullets used by the Japanese aircraft were not steel-core armor-piercing bullets, but ordinary lead bullets, which would shatter when they hit the armor, so they couldn't hit the armor at all.

At the beginning, the gunners of the Monkey King airship were inexperienced, and they were not allowed to hit the Japanese planes flying all over the sky, but soon they understood the amount of calculation in advance, and when they wanted to hit the Japanese planes, they aimed the muzzle at the front of the plane's flight trajectory and opened fire.

As soon as the new method of play came out, more than a dozen Japanese planes were hit by shells, and if the shells did not hit the key parts, the Japanese planes would not have fallen, so although more than a dozen Japanese planes were hit, only four of them crashed, one of them was the engine was broken, the propeller stalled, and fell directly, and one was the pilot was killed, and the other two were shells that detonated the fuel and exploded directly in the air.

The other planes that were hit were by no means unharmed, and the shells pierced the fuselage and wings, resulting in a significant reduction in flight performance, and some of the planes were unable to fight and staggered back to base.

The Japanese pilots also learned to fight in the battle, they found that the Monkey King's airbag was very safe, and the cannon could not hit, so they raised their altitude, flew to its top, and then dived down, Lin Gecheng had already prepared for this, and ordered the Monkey King airship to raise the altitude, and the operator immediately heated the helium to increase its lift, and the Monkey King airship climbed immediately.

Lin Fei's analysis before the war was really good, the ceiling of the Japanese aircraft was indeed not high, because the gasoline internal combustion engine needed oxygen when it was working, and the high oxygen was lacking, the Japanese aircraft was at an altitude of one to two thousand meters, and the engine power fell down "brush, brush, brush", and a Japanese plane climbed desperately because of chasing the Monkey King's airship, the engine stopped directly in the air, and the whole body fell down in a spiral.

If the Japanese ask Lin Fei to be a teacher, Lin Fei will tell them that your plane has entered a stall tailspin and must be changed, otherwise the plane will fall, as for how to change it, the premise is that you have a strong engine, but you use a piston engine, not a jet engine, and the power is only 40 kilowatts.
