Start with a blacksmith shop

It felt great to fly in the sky. He couldn't put into words how he felt now, let alone flying a model airplane he made.

Although he had already flown in the virtual laboratory, virtuality gave him a different psychological experience compared to reality.

The speed of 800 kilometers per hour can already be called subsonic speed at this time. Some old fighter jets may not have this speed.

Li Zhenhua, who was sitting in the cockpit, was still not very satisfied with the current speed.

Pushing the throttle push rod to the maximum, he wanted to see how fast the model airplane he built could fly in reality.

In the sky, the fuel level in the 475-liter fuel tank inside the model aircraft was swirling downward.

Oil is injected into the engine, mixed with highly compressed air in the engine, and explodes in the combustion chamber to produce high-temperature expanding gas, which is then sprayed out through the turbine's tail nozzle.

After these processes, the oil is also transformed from liquid into airflow with huge thrust, pushing the aircraft forward.

Since the accelerator was turned to the maximum, Li Zhenhua had no reference in his field of vision, and in his perception, the speed had not changed much.

However, the data displayed on the instrument transmitted back was different. The speed displayed on it had reached 1136 kilometers per hour, and the speed was still increasing.

This means that there is no one on the model aircraft. If there is anyone, if they don’t wear anti-G-forces suits and just go up there and fly so fast, black vision will definitely appear on the body.

Just when he was enjoying himself and getting a little carried away, just over a hundred kilometers away from them was the Quancheng Air Force Base.

If there is an air force base, there will definitely be a radar station. The radar station here monitors all the high and low airspace around the base.

Although route application is not here, it is connected to the civil aviation tower, and all routes in Kyushu are monitored by their department.

Fan Lei is a radar soldier at this radar station, and his job is to face the radar screen every day and record the passing aircraft in the airspace.

The work is boring, but for Fan Lei, it is also very meaningful. This job is also maintaining the safety of Kyushu airspace.

He had been sitting in front of the radar for too long that day. When he stood up and planned to stretch, report and go to the toilet,

My eyes accidentally saw a small green dot appearing on the screen. What does this mean?

It meant that an aircraft appeared on the radar. Seeing the appearance of the little green dot, his previous urge to urinate disappeared and his attention was focused on the little green dot.

He sat back down in his seat and took a few seconds to reflect on what he had learned today.

There was a patrol mission at the airport today, but at this time, it was not yet time for them to return. This was the notification he received early in the morning.

Moreover, if a civil aviation plane passes by, it will definitely have an aviation identification number, not the small green dot it looks like now.

Even if there was a temporary passing civil aircraft, a notice would definitely be sent, but Fan Lei thought about it carefully and no one informed him that there was a temporary passing aircraft.

After thinking about both the military and civilian situations, he ordered the radar in front of him again.

He rubbed his eyes to make sure that he had not seen anything wrong just now. The radar scan scanned the sky every five seconds.

Staring at the radar screen closely, five seconds later, the small green dot reappeared on the screen.

Fan Lei was finally certain that he had discovered something.

He really found the aircraft, an aircraft without any registration and no aviation identification number.

After several data refreshes, the various data of the small green dot were automatically calculated and displayed on the screen.

The speed is 834 kilometers per hour, and the speed is still increasing. It only takes three radar scans, which is fifteen seconds.

The speed of this aircraft has increased to 1,403 kilometers per hour, which is supersonic flight.

The speed of sound is 340M/S, and one hour is 3600S, which is 1224 kilometers per hour. This 1403 kilometers per hour has exceeded this speed.

What is the concept of an aircraft flying at Mach 1.1? It must be a military aircraft.

This is not a speed that a civilian aircraft can achieve, unless the Concorde supersonic passenger plane flying above is the ghost!

At the same time, he was controlling the model aircraft, which had just broken the sound barrier in the air. The sound inside the simulator transmitted the huge explosion sound received by the radio equipment on the model aircraft without any interruption.

But he didn't pay attention to the sound barrier. Instead, he turned his head and looked behind.

On the screen behind me, I saw that the sonic boom cloud created by a model aircraft that had just broken through the sound barrier was still in place and had not dissipated.

"Fuck, fuck, fuck," he said three times, showing his inner unrest. That was a sonic boom cloud, a sonic boom cloud produced by a model aircraft.

At the same time, Fan Lei was not at peace inside, and at the same time, there was a trace of anger in his heart.

While he was dazed, the speed of the aircraft on the radar screen had reached 1,836 kilometers, which was Mach 1.5.

At this moment, countless conjectures flashed in his mind, whose aircraft does this belong to?

Fan Lei could already feel his hair standing on end while he was checking in his mind which side it was from.

Then he looked at the radar screen again. After he saw the data displayed, he couldn't help but feel a little dazed!

The flight altitude was 498 meters, and looking at the area reflected by the radar, it showed that the aircraft only had a wingspan of 1.3 meters, but its length was 2.1 meters.

Yes, at this time, the wings of the aircraft model have been controlled by Li Zhenhua and have been folded to the maximum sweep angle. At a sweep angle of 75 degrees, the wingspan is only 1.9 meters.

What kind of thing could such a data aircraft be? People shouldn’t be able to sit in it at all.

Could it be a stealth reconnaissance aircraft from another country? The reflected fuselage area is smaller due to stealth?

But no matter what the situation is, it must be reported to the superior. In the empty radar station, he is the only one on duty at the moment.

He reached out to a red landline phone, picked up the phone, pressed the button, and took a deep breath after the call was connected.

"Leader, I discovered a supersonic aircraft in our airspace..."

I have been flying in the sky for nearly ten minutes. I can feel the joy of flying a fighter plane on the ground. This feeling is good, great and powerful.

Moreover, this aircraft model is 1.2 tons plus fuel, which is 1.6 tons, but the thrust is 2.8 tons. What is the thrust-to-weight ratio? This is a thrust-to-weight ratio of 1.75.

Nowadays, the Buddha 22 push-to-weight ratio in China may be around 1.2. The actual ratio may be higher or lower.

But with such a thrust-to-weight ratio, it can already perform many gorgeous tactical maneuvers.

Falling leaves, cobra excitement, barrel rolls, and bell maneuvers are all out of the question, let alone the model aircraft he is flying now.

With a push-to-weight ratio of 1.75, you can do any movement.

For aircraft, as long as the engine is strong enough, no matter how bad the starting layout is, even if it is a brick, it can still fly.

With excellent aerodynamic layout and powerful engine, many actions are a piece of cake for this model aircraft.

But if you ask him to do these actions, he will never do it. It's not that he doesn't want to do it, but that he doesn't know how to do it.

He sat in the cockpit and controlled the flight of the model aircraft, but the experience for people on the ground was not that good.

Because after the model aircraft flew into the sky, it only stayed in their sight for a short time before the model aircraft flew out of their sight.

He held his head high and searched all over the sky but couldn't find any trace of the model aircraft. He didn't know where Li Zhenhua was controlling the flight.

At this moment, it has been flying for twelve minutes, and it has been flying at Mach 1.5 speed for five minutes. In such a short time, it has flown 250 kilometers away.

In other words, at this moment, the model aircraft is already 250 kilometers away from them in a straight line. It’s weird to be able to see it!

Fan Lei reported what he discovered, and soon the director of the radar station rushed into the duty room with his people.

Fan Lei was pushed aside and his position was given to the stationmaster.

Then the stationmaster looked at the radar, which showed that the aircraft was flying in the airspace of 500 meters at a speed of Mach 1.5.

And it's not far from their radar station, only 30 kilometers away. And judging from the opponent's flight trajectory, it is likely to pass them in a few minutes.

After deducing this information, he immediately arranged for people to go to the open space outside to see what the thing was.

The webmaster did not just arrange this plan. He immediately used a red landline phone to broadcast a call and reported their findings to the Air Force.

Soon their intercom system was connected to a channel, a channel with only two units.

"This is the Falcon Team. I am the lead aircraft, Falcon One, and the remaining units are my wingmen, Falcon Two. Please repeat what you discovered!"

In the intercom system, a voice came from the speaker, and the radar station manager described the situation just discovered.

"... Falcon 1, you must be careful when approaching. The radar reflection area I obtained shows that its length is only 2.1 meters and its wingspan is only 1.3 meters.

Now I'm not sure if it's really that big, or if it's a stealth fighter, and the reflector we get after camouflage is that big! "

Just as the stationmaster was reporting the situation, the door was pushed hard from the outside.

A soldier ran in and shouted to the station commander: "Station commander, I saw it, I saw it, it..."
