The feeling of flying in the sky is great, and his current feeling can't be expressed in words, let alone flying a model airplane made by himself,

Although he had already flown in the virtual laboratory, the virtual and the real gave him a different experience psychologically.

The speed of 800 kilometers per hour can already be called subsonic at this time, and some old fighters do not necessarily have this speed.

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

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

In the sky, the fuel level of the 475-liter fuel tank inside the model airplane is swirling down.

The oil is injected into the engine, where it is mixed with highly compressed air, which explodes in the combustion chamber to produce a high-temperature expansion gas, which is then ejected through the turbine at the tail nozzle.

After these processes, the oil is also converted from a liquid into a stream of air with tremendous thrust that pushes the plane forward.

Since hitting the throttle to the maximum, Li Zhenhua's field of vision has no reference, and there is no change in speed in his feelings.

However, the data on the transmitted meter shows a different picture, which shows that the speed has reached 1136 kilometers per hour, and the speed is still surging upward.

This is also the model airplane no one, if there is someone, do not wear anti-load clothing, just go up, fly so fast, there will definitely be black vision on the body.

Just when he was having fun and getting a little carried away, just a little more than a hundred kilometers away from them was the Quancheng Air Force Base.

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

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

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

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

He had been sitting in front of the radar for too long that day, and when he just stood up and was about to stretch and report to the toilet,

What does it mean when I inadvertently see a small green dot on the screen?

It means that a flying machine appeared on the radar, and when he saw the appearance of the small green dot, he had no intention of urinating just now, and his attention was focused on this little green dot.

Sitting back in his seat, he took a few seconds to reflect on what he had been given today.

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

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

Even if there is a civil aircraft that passes temporarily, it will definitely send a notification, but Fan Lei thought about it carefully, and no one informed him that there was a temporary passage of the aircraft.

After thinking about the situation on both the military and civilian sides, he ordered the radar in front of him again,

Rubbed his eyes and confirmed that he was not dazzled just now, the radar scan was sweeping the sky every five seconds,

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

Van Lei could finally be sure of what he had discovered.

He really found the flying machine, a flying machine that didn't have any filings, no aviation identification number.

After several data refreshes, all kinds of data of the little green dot are automatically calculated and displayed on the screen.

The speed is 834 kilometers per hour, and the speed is still surging, just three radar scans, that is, fifteen seconds,

The speed of this aircraft has increased to 1403 kilometers per hour, which is supersonic flight.

The speed of sound is 340 m/s, and an hour is 3600s, which is 1224 kilometers per hour, which is already more than this speed.

A flying machine that is flying at Mach 1.1, what is this concept, it must be a military aircraft,

That's not the speed that a civilian aircraft can achieve, unless it's a hell of a Concorde supersonic airliner flying on it right now!

At the same time, he was controlling the model airplane, and had just broken through the sound barrier in the air, and the sound inside the simulator transmitted the huge explosion sound received by the model airplane and the radio device without pulling it at all.

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

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

"Grass,, trough" said three times, showing his inner unpeace, it was a sonic boom cloud, a sonic boom cloud produced by a model airplane.

At the same time, Fan Lei's heart was also not calm, and at the same time, there was a trace of anger in his heart.

In Kyushu, someone else's military aircraft actually appeared, which is a shame for these soldiers.

During the time he was stunned, the speed of the aircraft on the radar screen had reached 1,836 kilometers, that is, the speed of Mach 1.5.

At this moment, countless conjectures flashed in his mind, whose flying machine did this belong to?

Small day? He didn't have that guts!

Moldy country? It shouldn't be possible, not to mention the distance, and now it doesn't dare to enter the airspace of Kyushu casually.

A third brother? It would be even more unlikely, although they are the second most populous country in the world,

But with their brilliance, it's good to be able to keep the record of zero crashes.

Besides, Ah San is close to the west of Kyushu, and the East Mountain where they are located is east of Kyushu, separated by more than 3,000 kilometers, so it is impossible to appear in the East Mountain.

Checking in his heart what kind of force it was, Fan Lei already felt his hairs stand upside down at this moment.

No matter which side it is, it must be the imperialist selflessness, and this supersonic flying thing above must be the enemy's reconnaissance plane.

Then he looked at the radar screen, and after he saw the data displayed, he couldn't help but be a little stunned!

The flight altitude is 498 meters, and looking at the area reflected by the radar, it shows that the aircraft only has a wingspan of 1.3 meters, but the length is 2.1 meters.

Yes, at this time, the wing of the model aircraft has been controlled by Li Zhenhua, and it has been retracted into the maximum sweep angle, with a 75-degree sweep angle and a wingspan of only 1.9 meters.

What will such a data aircraft be, people should not be able to sit in it at all,

Could it be a stealth reconnaissance aircraft of another country? The area of the reflected fuselage is relatively small due to stealth?

But no matter what the situation is, this has to be reported to the top, in the empty radar station, as long as he is on duty at this moment,

He reached into a red landline phone, picked up the microphone, pressed it to write it down, and took a deep breath when the call was connected.

"Leader, I found a supersonic vehicle in our airspace..."

I've been flying in the sky for almost ten minutes, and it's nice and great to be able to feel the joy of flying a fighter plane on the ground.

And this model aircraft is 1.2 tons plus fuel, which is 1.6 tons, and the thrust is 2.8 tons, what is the thrust-to-weight ratio, which is 1.75 thrust-to-weight ratio.

Nowadays, the thrust-to-weight ratio of Buddha 22 in the moldy country may be about 1.2, and the actual may be high or low.

But with such a thrust-to-weight ratio, it can already play a lot of gorgeous tactical maneuvers.

What fallen leaves, cobra excited, barrel rolling, bell-shaped maneuvering, all of them are not a problem, not to mention the model airplane he is flying now,

1.75 thrust-to-weight ratio, but you can do anything.

For an aircraft, as long as the engine is strong enough, even if the starting layout is bad, even if it is a brick, it can fly.

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

But if you want to ask him to do these actions, he will never do them, not because he doesn't want to do them, but because he won't do them.

He himself sat in the cockpit and controlled the model airplane flight, but the experience for the people on the ground was not very good.

Because after the model airplane flew into the sky, it only stayed in their sight for a short time, and the model airplane had already flown out of their field of vision.

Holding his head high, he couldn't find any trace of the model airplane in the sky, and he didn't know where Li Zhenhua flew under his control.

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

That is, 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!

It is said that Fan Lei reported what he found, and soon the stationmaster of the radar station rushed into the duty room with people.

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

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

And it is not far from their radar station, only 30 kilometers away, and looking at the flight trajectory of the other side, it is likely that it will pass through their side in a few minutes.

After calculating this information, he immediately arranged for someone to go to the open space outside to see what that thing was.

And the stationmaster did not only arrange this plan, he immediately used the red telephone landline to broadcast a phone call, informing the air force of their discovery.

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

"This is the Saker team, I am the long-time Saker No. 1, and the rest of the unit is my wingman, Saker No. 2, please repeat the situation of your discovery!"

In the intercom system, a voice came out of the loudspeaker, and the radar station commander recounted what had just been discovered.

“··· Saker One, you have to be careful when you approach, I got the radar reflection area, its length is only 2.1 meters, and the wingspan is only 1.3 meters,

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

Just as the stationmaster was briefing him on the situation, the door was pushed open from the outside.

A soldier ran in and shouted to the stationmaster, "Stationmaster, I see it, I see it, it's just..."
