He Zhimin looked at Zhou Yuankai and asked: "There are many ways to intercept? Please tell me..."
"For example, ground air defense troops!" Zhou Yuankai said: "Use anti-aircraft machine guns and anti-aircraft guns..."
Chen Songyong interrupted Zhou Yuankai: "Captain Zhou, the interception efficiency of anti-aircraft machine guns and anti-aircraft guns is too low. It is difficult for them to hit targets as big as planes, let alone targets as small as 'high fire'!"
Zhou Yuankai shook his head and said: "Commander Chen, we have to consider something: although the target of 'High Fire' is small and difficult to aim at, firstly it is slow, secondly it cannot maneuver to dodge, and thirdly it is very fragile without armor.
Any impact or shrapnel can break it or cause it to crash!"
After hearing this, the crowd became silent.
Then Zhou Yuankai added: "The most fatal flaw is that the 'High Fire' is a set altitude. When the 'High Fire' is launched, except for changes in altitude during the climbing phase, it remains stable at 700 meters most of the time.
It reaches an altitude of 900 meters, and once it reaches this altitude, it will not change. It will maintain this altitude until it flies over the target. Do you know what this means?"
Seeing the confused faces of the surrounding soldiers, Zhou Yuankai revealed the answer: "It is true that the enemy's aircraft cannot intercept the 'high fire', but they can detect it. Once their pilots detect our army's 'high fire', they can immediately
The barometric altimeter on the aircraft knows the exact altitude of the 'high fire'. It then notifies the anti-aircraft artillery unit of this altitude data and ballistic direction..."
At this point, everyone understood.
Wang Xuexin nodded in agreement.
Zhou Yuankai is a pilot, and he thinks about things from a different perspective than others. He thinks about how to fly, how to avoid enemy air defense forces, etc. all day long. At this time, he put this habit into "High Fire"
.
From this aspect, Wang Xuexin's choice to make Zhou Yuankai the captain of the "high fire" unit was a very wise choice.
He Zhimin also understood at this time. He quickly drew a few lines in his notebook to calculate, and then said: "If calculated based on thirty kilometers, the 'High Fire' needs to fly for six minutes, of which about four and a half minutes are
Flying at the same altitude, according to Captain Zhou, the enemy's air defense forces may obtain 'high fire' data during this period and prepare in advance..."
Professor Su asked: "Is the Japanese reaction so fast? Four and a half minutes. This period also includes the pilot's reconnaissance, communications, etc."
Wang Xuexin said: "The Japs don't need such a quick response, they just need the range of the anti-aircraft guns to be far enough."
He Zhimin was stunned for a moment, and then he understood.
A long enough range means that anti-aircraft guns have a greater chance of hitting "high fire" without maneuvering, and the flying height of "high fire" is only more than 700 meters... This gives the Japanese anti-aircraft guns a lot of interception space.
Especially for large-caliber anti-aircraft guns, the shells have pre-adjusted delay fuses.
If this is a high-speed aircraft, the probability of an anti-aircraft gun hitting it is indeed low.
Because the plane not only flies fast, but also can change its flight path and altitude at any time as long as the pilot is willing.
This makes it difficult to set the delay fuse of the anti-aircraft gun. Even if the setting is accurate at that time, the trajectory and height of the target will change during the launch of the artillery shell, which makes it very difficult for the anti-aircraft gun to fly.
This is one of the reasons why proximity fuzes are so important.
If the anti-aircraft gun has a proximity fuze, there is no need to adjust the delay fuze. It will automatically detonate at the position closest to the target, thus greatly increasing the hit rate.
Now, although the Japs do not have a proximity fuse, the "High Fire" flies at a constant altitude and in a constant trajectory throughout the whole process. Doesn't this mean that the Japs have a proximity fuse?
As soon as the Japanese anti-aircraft artillery troops get the data, they can immediately calculate the angle at which the anti-aircraft artillery needs to be fired and the firing height. Then, with the cooperation of the reconnaissance aircraft, they can open fire and even conduct test firings... Then intercepting "high fire" is not just one block at a time.
allow?
After a moment of silence, He Zhimin, who looked ugly, turned to Zhou Yuankai and asked, "Is there any other way?"
"You can also use hot air balloons!" Zhou Yuankai said: "When the bear loses in the air, he will use a large number of hot air balloons for air defense."
As he spoke, Zhou Yuankai took two pieces of straw paper and crumpled them into balls to serve as two hot air balloons. While demonstrating, he said: "For example, these two hot air balloons are connected by two steel cables after they rise into the air, and they will appear in the middle."
There is a blocking rope, once 'Gao Huo' hits the blocking rope..."
Needless to say what will happen, the "High Fire" is very fragile. If it crashes like this, it may disintegrate in the air, and the fragments will be picked up by the Japanese for study.
He Zhimin asked in confusion: "This is just a blocking rope. Isn't the efficiency too low?"
"He Lao!" Zhou Yuankai explained: "Hot-air balloons are very cheap and can be used repeatedly. There can only be one blocking rope between two hot-air balloons, but what about three? What about four, five or even more?
"
The number of these blocking ropes is amazing, because they can be connected two by two, and the whole thing will look like a spider web in the end.
Wang Xuexin actually knows these methods.
Because these are the methods used to deal with Hans' v1 missiles until the sun never sets in history...
The first is to use fighter planes to intercept. Hans does not have a proximity fuze, so fighter planes that never set can safely intercept.
The second is to use hot air balloons to lay an air defense barrier around the capital.
The third is to use anti-aircraft guns.
However, Sun Never Set's anti-aircraft guns did not need to cooperate with reconnaissance aircraft, because Sun Never Set had already obtained the proximity fuze from Yingjiang at that time, and it could still effectively intercept without knowing the altitude data.
Therefore, although the number of V1 missiles that Hans used to hit the capital city of Never Set in the past was large, the damage they could cause was very limited. They either malfunctioned on the way and escaped from the route, or they were intercepted by Never Set.
Calculated from this aspect, the funds Hans spent on v1 missiles are not worth it... Some people have calculated that the funds Hans spent on developing v1 and v2 can produce 24,000 aircraft.
Obviously, their role is not as great as that of 24,000 aircraft.
If there is any contribution to this project, it is that after it was handed over to Yingjiang and Mao Xiong, it saved them a lot of financial, material and time resources in developing missiles and rockets.
Seeing that Zhimin and Professor Su were all silent, Zhou Yuankai asked: "Can we change the flight altitude and trajectory of 'Gao Huo'?"
Professor Su shook his head in distress: "Although it can be changed, once it is changed, its flight trajectory will become extremely complicated. Coupled with the error of the control system itself... it will be difficult to hit the target!"
Therefore, the improvement of "high fire" has reached a dead end: it will not be able to hit the target if it changes trajectory, and it will be intercepted if it hits the target.
