After that, the anti-aircraft missiles encountered no major problems. The first batch of three samples was produced and put into testing immediately.
The experiment was very successful. Although there were some abnormalities in the second ignition stage in the air, it was overall a success.
He Zhimin estimated that the abnormality in the mid-air ignition this time was because the rocket's main engine did not reach the maximum thrust at the moment of ignition. It requires a gradual increase process, and the computer's response speed was too fast and had already forcibly adjusted the missile wing to adapt to the main engine.
The engine reached maximum thrust, and then there were signs of a bit of loss of control.
This loss of control is no small problem.
Because the missile itself has a self-adjusting function, when the missile loses control, the gyroscope will issue a series of instructions to the flight control system. At the same time, the thrust of the main engine is constantly increasing... This is consistent with the commands given by the flight control system.
The conflict ultimately leads to total loss of control.
However, this problem was quickly solved by He Zhimin.
The solution is to delay the time and number of times the computer actively adjusts the wings during the mid-air ignition phase.
He Zhimin said this: "The thrust of the main engine is not large when it is just ignited, which has little impact on the missile. At this time, the missile's own stabilization system, that is, the gyroscope, can be used to maintain the flight attitude without computer intervention. Only
When the engine thrust reaches the maximum or is close to the maximum in a short period of time, the response speed of the gyroscope cannot keep up with the computer before intervention is required, and I think it should not be done once, but multiple times and reduce the scope of intervention!”
Wang Xuexin agrees with this solution.
One intervention is too drastic and the gyroscope's flight control system is completely ignored at that moment, which is likely to be counterproductive. Reducing the degree of intervention and increasing the number of interventions is equivalent to fine-tuning, allowing both the computer and the gyroscope to participate in the process and move in the best direction together. The effect
Could be better!
This is very simple for the computer, and Chen Jiefeng only needs to change the program wiring.
So on the ninth day, the third anti-aircraft missile was launched.
This anti-aircraft missile performed quite stably during the ignition stage in the air at a distance of ten kilometers. The whole process only had slight vibrations and then it maintained a stable attitude and flew towards the target direction.
Everyone couldn't help but cheer and clap their hands to celebrate.
Originally, this anti-aircraft missile needed to undergo more tests and make more improvements before it could enter mass production, but the urgency of the war did not allow the Eighth Route Army to do this.
Wang Xuexin ordered: "Immediately put into mass production, and strive to have fifty extended-range anti-aircraft missiles in ten days!"
"Yes!" the researchers responded.
Fifty coins in ten days, an average of five coins per day.
This workload is indeed quite large, but it is not an impossible task.
The reason is that this missile is an improved version of the original anti-aircraft missile. All it needs is a booster added to the original anti-aircraft missile and a small computer used to control aerial ignition.
However, Wang Xuexin's words puzzled Chief Na.
The commander sent a telegram asking: "Comrade Wang Xuexin, we will launch a full-line offensive in a few days, but the anti-aircraft missiles will not be ready until ten days... Have you miscalculated the time?"
The attack time decided by the headquarters was similar to Wang Xuexin's estimate. The total attack time was on the thirteenth day.
The anti-aircraft missiles took nine days to develop and ten days to produce, adding up to nineteen days, a full six days later than the general attack time!
Wang Xuexin replied: "Chief, your calculation is correct!"
"How come the calculation is not wrong?" The chief asked again: "You are not right at the right time!"
Wang Xuexin replied: "Chief, first of all, every batch of anti-aircraft missiles we produce will be shipped to Chifeng. Chifeng will be able to get several anti-aircraft missiles when attacking. In other words, the frontline troops will not be helpless even if they encounter enemy anti-tank fighters.
!”
The leader couldn't help but nodded after hearing this. If calculated at five per day, there would already be twenty when the general attack was launched.
If twenty extended-range anti-aircraft missiles can play a role on the battlefield, they will immediately frighten enemy fighter planes. The enemy will not dare to act rashly without knowing how many extended-range anti-aircraft missiles the Eighth Route Army has.
However, it would be bad if the Japanese got jealous and sent a large number of fighter planes to bomb!
So the chief asked again: "What else?"
"More importantly!" Wang Xuexin analyzed: "If I were the Japanese, I would not invest in this secret weapon at the beginning of our attack. There is no benefit in using this secret weapon too early. It just makes our army afraid.
It's just an attack. If the main force of our army has penetrated deep into the enemy's hinterland and even reached the gates of Fengtian City, and then the Japanese suddenly use these fighter planes to destroy our tanks one by one..."
The chief laughed "haha": "It's not bad, it's very thoughtful and makes sense!"
What Wang Xuexin said does make sense.
At this time, Naosaburo Okabe was eager to win a victory. The Eighth Route Army's attack was a rare opportunity for him, especially since he had a secret weapon in his hand.
At this time, any normal person would think: Can we wait until the enemy is surrounded and then launch a counterattack? If fighter planes suddenly appeared and destroyed the tanks of the Eighth Route Army one by one, wouldn't it be the imperial army chasing the Eighth Route Army next?
This time, Naosaburo Okabe was correctly predicted by Wang Xuexin, and he made exactly this plan.
During this period, Naosaburo Okabe became more and more convinced that the Eighth Route Army was going to launch an attack, and it would be an attack of unprecedented scale.
The Eighth Route Army has only two possible directions of attack:
One is to attack Manzhouli from Duolun County to the north.
The other is to attack from Chifeng towards Chaoyang.
The former is almost impossible. Although it is possible to attack from this route and the Mao Xiong army attack Manzhouli from both sides, the imperial army has built a solid fortress in Manchuria.
Attacking these fortresses cannot be accomplished with more troops, not to mention that Mao Xiong himself has no shortage of troops.
Therefore, the Eighth Route Army's attack from this route will not accomplish much and will not have much effect.
It is more likely to attack from Chifeng in the direction of Chaoyang, because this way will lead directly to the hinterland of the empire, especially Fengtian City not far away is an important military industrial base of the empire.
At that time, the Eighth Route Army and Mao Xiong's army will be able to form a pincer attack on the imperial army from both inside and outside: Mao Xiong is attacking the Kanto Fortress from outside while the Eighth Route Army is running around inside, and then the empire will be in chaos.
Naosaburo Okabe stared at the map.
He believed that to avoid this situation, the Eighth Route Army's offensive must be defeated in the shortest possible time, and it would be best to kill a large number of its effective forces.
In this way, the furry bear might be shocked, and he would not dare to act rashly!
