country made

On the Yigao booth, Ji Yu and Song Jining opened the box, took out various tools and accessories, and started assembling.The two were very fast and quickly assembled a set of special models.

Looking at some missile launchers similar to those reported in newspapers, there is also a missile-like model made of iron cylinders on it.But it was simplified because of the material, and it looked like a rough toy—but all in all, someone with military knowledge could tell that it was a missile launcher.The function of the launcher is very simple, only one catapult is installed, and the angle and strength have been accurately calculated to ensure the direction and angle of the "missile" flying out.On the contrary, it looks like a missile made of a cylinder. The outside and inside are just cylinders, but the weight is exactly the same as the weight of the M33 missile.

Every piece of data in the land-based mid-course defense system is extremely important, and if you make a mistake, you may make a total error. Therefore, as far as possible, Ji Yu calculated it according to equal proportions, trying to reduce difficulties for other researchers.

The students at the nearby school couldn't help laughing when they saw the crude launcher and missiles.A high school student glared at him, and turned back to firmly block the booth so that no one could see him. At the same time, he asked Ji Zhuan anxiously, "Ji Zhuan, what is this? Is it still okay?"

Ji Yu and Song Jining are still assembling the kinetic energy interceptor. It looks weird, like a millstone with a chimney added to it, and the chimney is covered with various wires and sensors.It also comes with an interceptor missile, whose diameter is one-third smaller than that of the other model missile, and its weight and size are also reduced in proportion to the real thing, but it still only has the outer shape, and the inside is an empty tube.

After assembling, it looked like it finally had some appearance, but after all, it was different from the "robots" that everyone knows so far. According to the level of the national finals, the style was too simple and rough, and even the wires were exposed, not like an active robot. , function unknown.

Zhou Chong and Zeng Zhijie approached and asked, "Ji Zhuan, what are you doing?"

The friends naturally also participated in the robot competition, but this time the opponents were too many and too strong, only about half of the friends entered the finals, and the others were eliminated.

Anyway, this group of friends would never doubt the level of Ji Yu and Song Jining, so they only curiously asked about its function.

Ji Yu shook his head with a smile: "You will be able to see it when it's time for the demonstration."

Song Jining: "That's right, wait for the shock!"

God knows that he has never seen it himself, because there are only three starter lithium batteries, which are only enough for two startups, so Ji Yu didn't use it once. Whether the effect of Ji Yu's design will appear, Song Jining is not sure.But in front of outsiders, he always supports Ji Yuan at all times.

Not only the little friends paid attention to Yigao’s booth, but also the former champions and competitive schools. At present, many students came over curiously, and the TV station also came to interview and asked Ji Yu: "Student, what is your name?" The robot seems to be different from others, what function does it have?"

Ji Yu nodded and explained a little more to the TV station: "It's called a land-based mid-course defense system, or it can also be called an anti-missile system. The expected function is to locate the trajectory of the ballistic and intercept it in the middle."

He tried to speak as simple and understandable as possible, so the reporters and onlookers understood it, and then let out a chuckle: "That's a good idea...but it's not a robot, is it?"

In their view, this technology is just the imagination of a middle school student, so no one cares about it, and only considers whether it is a robot.

After all, this is a robot competition.

Ji Yu didn't bother to explain too much, just said: "From the current technology, it still belongs to the category of intelligent robots."

However, scale-up physical objects are not robotics.

Several judges came to Yigao's booth soon, saw the two instruments on the booth, and asked curiously, "Student, what kind of robot is this?"

In the face of experts, Ji Yu naturally explained from a professional perspective: "This is a land-based mid-course defense system. Its conceived principle is to provide early warning and target identification for ballistic missiles, and guide the command and control communication system. This is an anti-ballistic missile. The interceptor of the defense system, which is an interceptor for surface-to-air missiles, is assumed to be launched vertically from the silo, and can deal with strategic missiles attacking from all directions."

Those few judges were stunned when they heard it, and felt that the student's idea was really whimsical, intercepting ballistic missiles?Does he know what a ballistic missile is?But after thinking about it, I felt that this idea seemed good, so I said, "Then why don't you show it to us?"

Ji Yu nodded: "I divide the ballistic trajectory into high-altitude (outside the atmosphere) and low-altitude (inside the atmosphere) interception according to the interception airspace. The middle defense system belongs to high-altitude interception, and it is aimed at the latest M33 missile of the US Empire."

One of the judges laughed: "Do you still know the M33 missile?"

Ji Yu froze for a moment, then nodded: "I saw it on "Reference News"."

At that time, the M33 missile was the latest ballistic missile of the U.S. Empire. When developing a land-based mid-course defense system, the U.S. Empire also conducted research with the goal of intercepting it, because the U.S. Empire believed that if it could intercept its own best missile, it would naturally be able to intercept the world. missiles.When Ji Yu wrote the thesis, both the old version of the land-based mid-course defense system and the M33 missile had already withdrawn from the stage of history. Fortunately, there were detailed introductions in the "Reference News" newspaper and internal materials.

"Oh, the younger students also like to read "Reference News"?"

Suddenly, many students raised their hands: "I have also read "Reference News."

"Me too, I've seen it too!"

It seems that there are quite a few students who like to learn about current affairs and foreign news. The judges had to praise them all, and quickly turned back to the topic: "This... Student Ji Yu, can you start the demonstration?"

Ji Yu nodded and looked at Song Jining: "Let's get started!"

The two occupied a corner of the booth. While checking and debugging the machine for the last time, they explained: "As long as the energy is sufficient, the land-based mid-course defense system can automatically operate and sense 24 hours a day without manual operation. Suppose I am at the border. Arming..." He placed the kinetic energy interceptor, put in the interceptor bomb, turned on the power, and then walked aside with his hands behind his back: "When the US M33 missile launches a surprise attack on our side, but I don't know anything about it ..."

At this time, Song Jining pressed the switch and activated the M33 missile model.The model flew up, shooting towards the quarter rafters.

"Beep beep—!!"

The sensor module outside the kinetic energy interceptor issued an early warning, and the chimney-like top rotated in the direction of the "missile", and quickly launched the interceptor bomb, shooting down the M33 missile model in mid-air.

The preparation is flawless.Before the audience had time to praise, they saw two missile models flying into the faces of the judges next to them due to the excessive ejection force, causing an uproar.

The teachers and students of No. [-] High became nervous instantly, and the students from several schools next to them snickered, obviously thinking that No. [-] Gao was about to offend the judges.

Ji Yu scratched his head, and reluctantly took the two models back: "Sorry, teacher, they were supposed to explode in the air, but these are just models, so..."

The power of the two iron and copper was not covered, and the faces of the judges were all red.

"Forget it...forget it..." After all, it is against the students, and the judges don't want to get angry. They covered their faces and said, "The idea is very good, the next one..."

"Kinetic Interceptor."

"Well, the kinetic energy interceptor is also very good, very smart..."

Although I think this idea is good, I also think that Ji Yu is taking it for granted, because the M33 missile he designed can only be hit because it is a model, and the real missile is not so easy to be locked.

"Has the route of your missile been set up?"

Due to the responsibility of the judges, they still pay more attention to the intelligence of the robot.If the missiles and interceptors just set a route and ejection time, it is not surprising to hit each other in the air, and it is not considered smart. Ordinary toys can do it.

Ji Yu shook his head: "The missile is set, but the kinetic energy interceptor is not. It can be adjusted according to any orbit. Teacher, you can come and try it yourself. But it only has one power supply left."

"Okay, I'll give it a try."

The teacher who was hit by the missile model took the M33, stood in Song Jining's position, and adjusted the catapult underneath to a new angle.Another judge came to Ji Yu and said, "Let me try it too. I want to see if this kinetic energy interceptor is really intelligent."

He checked the kinetic energy interceptor, and after confirming that it was not set at a fixed angle, he deliberately changed the direction to the opposite direction, and installed its exit facing the outside audience into the interceptor missile.

The M33 missile model starts up again, and the launch angle is completely different from before. It flies high and then falls. In the eyes of everyone, the kinetic energy interceptor that was originally pointed at the audience emits a beep warning sound, and quickly turns the muzzle, launches, and falls. Half of the M33 missile models were knocked into the air again.

This time the confirmation is correct, the kinetic energy interceptor does have good intelligence.

Several judges couldn't help applauding: "Very good, very sensitive intelligence."

Hitting moving objects in the air is not something that can be done casually. From the perspective of a robot, it is indeed very sensitive.

After all, it is a simplified model, and the designers are only two high school students (Ji Yu insisted on adding Song Jining’s name), so it is impossible for the judges to have a scene like “Wow, my country’s national defense is saved”. In their eyes, It's the equivalent of watching a student make a Frisbee and say "I made a spaceship", and the encouraging compliments are enough, really being silly.

However, they agreed with Ji Zhuan's thinking, and the kinetic energy interceptor did a good job, so they still gave the highest score.

The robot competition ended, Yigao won the second championship trophy, this time the trophy was much more refined than last time, and the organizer also gave each contestant of the championship team a bonus of 100 yuan—not as much as the school gave.But the most important thing is to participate and to add points in the college entrance examination, so the students in No. [-] High School are still very happy.

Ji Yu was a little helpless. Due to the material, the kinetic energy interceptor was made more simplified than the design drawing, and its function could not be seen just by looking at its appearance.If you hand over the design drawings to someone who knows the goods, the other party should be able to see it, but he doesn't know who to hand it to——Professor Jiang's work has nothing to do with the military, and he will have to transfer it to Professor Jiang several times. I don't know at hand.

After thinking about it, it seems that only Lan Yutian's research institute is related to the military, or should he go back to them after the holiday?

Ji Yu was a little frustrated. The identity of a high school student was too restricted. He had already produced a sample, but in the eyes of others, it was just a "teenager's whimsy". If he was a graduate student now, he could at least apply for project approval.

Due to age and status, the kinetic energy interceptor designed by Ji Yu was naturally ignored.However, no one expected that it caused a shock abroad.
