The test flight went smoothly, except for a small hiccup.
The flying speed of the prototype is about 300 miles per hour, while the top speed of the Type 95 reconnaissance vehicle is only 70 kilometers per hour. Therefore, even if the Type 95 reconnaissance vehicle slams on the accelerator to catch up on the ground, it will be left behind in the blink of an eye.
Being left behind is not a problem at first, because the prototype can fly by itself, and the contact distance of the radio station is hundreds of kilometers... In fact, it is not just hundreds of kilometers, hundreds of kilometers is the contact distance between the ground and the ground, and the contact distance between the ground and the air
The contact distance is much greater.
The problem is that the prototype has no windows and cannot see the outside world. It needs ground observation and tells Zhou Yuankai its height, direction, attitude, etc. through radio.
If these guidelines are lost, the prototype aircraft will not be able to land, and it will be problematic to grasp the direction.
Seeing that the prototype was getting farther and farther away from the visual distance of the reconnaissance vehicle, He Zhimin suddenly made a wise decision and ordered Zhou Yuankai through the radio: "Run around in circles and wait for the reconnaissance vehicle!"
Zhou Yuankai responded and drove the prototype in circles.
Later, it was discovered that this was not possible because the prototype was about to run out of fuel and lose power, and it would fall from the sky before the reconnaissance vehicle arrived.
So the prototype aircraft headed towards the preset landing site, another small airport, the original airport, under the guidance of the reconnaissance vehicle.
All the processes went smoothly. Ten minutes later, Wang Xuexin received the information of successful landing, and the entire launch site burst into cheers.
Professor Su looked at the speed recorded by He Zhimin in disbelief and asked, "Lao He, is the speed calculated correctly?"
He Zhimin looked at the records and immediately realized something. He flipped through the records and said excitedly: "The calculation must be correct. The speeds recorded in several sections are all around 300 kilometers per hour!"
Wang Xuexin saw that the two people looked different, so he stepped forward and asked: "Professor Su, do you have a question?"
Professor Su quickly replied: "No, no, no problem!"
Then he added: "But there is indeed a problem!"
With that, he took the record book from He Zhimin and handed it to Wang Xuexin, saying: "Battle Commander Wang, look at this speed. It's 300 kilometers per hour. This is much faster than we imagined. At this speed, our ten
Minutes of fuel... that’s a flight of 50 kilometers!”
He Zhimin then said: "I think it's more than that! Because we also consumed some fuel when we landed, maybe there is still some fuel left."
Wang Xuexin nodded and agreed with He Zhimin's point of view, "It is impossible for Zhou Yuankai to control it just right and land just after consuming all the fuel. This is unnecessary and very dangerous."
That is to say...
Professor Su said: "The range of our prototype aircraft may not be more than 50 kilometers, which is nearly twice as far as the 30 kilometers we expected!"
Wang Xuexin thought for a while and then reminded: "Maybe we are not that optimistic. The reason is that we did not install explosives. If we follow our plan and install 800 kilograms of explosives in front of the nose, it will increase a lot of load whether it is ejection or flight, so
The voyage distance will also be reduced accordingly!”
"That's right!" He Zhimin said while calculating on his notebook, and then came to the conclusion: "But even with this added weight, our prototype can still glide for a certain distance in the air, so..."
He Zhimin did not continue. He quickly drew pictures and arranged formulas on his notebook with the pen in his hand. After a few minutes, he finally came up with the result and said: "The final range of the prototype is probably still 50
About kilometers! Of course, the exact number will only be known after actual testing after loading!"
The researchers around him were excited again after hearing this.
Although the range has been reduced, it is still far beyond the plan, not to mention that the range can be extended by improving the propellant or adding an engine.
Wang Xuexin believes that this range is sufficient, at least to deal with the current Yuncheng crisis.
As long as this thing can be successfully developed, where can the Japanese heavy artillery troops go?
The heavy artillery force may be moved in a few minutes, or it may not.
Because the Japs don’t think that the Eighth Route Army has equipment that can threaten heavy artillery, unless it’s an airplane...Heavy artillery can hit for more than ten kilometers. The Eighth Route Army has nothing on land that can hit that far, and if planes are used for bombing, the Japs can use it from a long way away.
The radar alerted him.
This is when this "high-precision rocket" comes into play.
Even if the Japanese realize that the Eighth Route Army has equipment that can threaten heavy artillery, "high-precision rockets" can still pose a threat to it.
Wang Xuexin started another calculation in his mind, or it could be said that there was a simulated artillery battle:
When the Japanese heavy artillery fires the first shell, it means that their artillery position has been exposed. The Eighth Route Army artillery scouts will calculate the coordinates of the enemy's artillery position at this time.
After the Japanese fired a few rounds of artillery shells, which was a few minutes later, our artillery scouts should have calculated the coordinates and sent them to the "high-precision rocket" troops.
The Japanese used heavy artillery, and it was difficult to transfer the weight of the cannon. It would take at least ten minutes to do so.
This time is enough for the prepared "rocket" troops to launch the "high-precision rocket" at a speed of 300 kilometers per hour. It only takes four minutes to cover 20 kilometers. The key point is that each prototype is equipped with 800 kilograms of explosives.
If this happens, there will be no grass growing for hundreds of meters nearby...
"Captain Wang, Commander Wang..." Professor Su pulled Wang Xuexin back from the simulated artillery battle: "Should we rush to Yuanchang Airport? What is important is the data of the prototype..."
Professor Su is right. The reason why they are spending so much money on this test flight is to use the data of the prototype to complete the "autonomous driving" of the prototype.
If the prototype cannot drive automatically, it will definitely be unrealistic for humans to fly these "rockets" towards the target. Wouldn't they become the Japanese's "Sakura Bombs" and "Kaitian Torpedoes"?
Wang Xuexin responded, and then got into a car with Professor Su and others and headed towards Yuan Chang.
In the car, Wang Xuexin said to Professor Su: "Professor Su, leave the recording and compilation of data to me. This is not a technical job. My subordinates and I..."
As he spoke, several of the guards around Wang Xuexin raised their heads: "We can't help with other tasks, so leave these physical tasks to us!"
Professor Su looked at Wang Xuexin as if he were a monster, and thought to himself: "Is this guy deliberately mocking us old guys? He can't help with other tasks? It's obviously all caused by you, not us.
I can’t help you, okay?”
However, Professor Su thought so in his heart, but did not say anything. He only replied coldly: "Okay, you can do it. Anyway, this is all under your command. You can do whatever you want. We don't have it."
The right to decide!”
Wang Xuexin felt a little strange when he touched this soft nail. He didn't understand how he had offended Professor Su and made him always look down on him.
