A big country of aerospace with black technology

The huge mechanical arm on the launch tower slowly loosened its connection with the rocket.

At the launch site control center, everyone present was very nervous.

After all, the "Hongyan No. 1" launched this time is different in all aspects from the various rocket models that were often launched before.

So everyone has no idea in their hearts, and they don't know whether this launch will be successful or not.

Because this is the first prototype rocket, the verification of the recovery of the first-stage rocket will not be carried out. After the first-stage rocket is separated from the second-stage rocket, it will control itself and fall into the East China Sea.

Before the experiment started, several sea salvage ships were on standby at sea.

Just waiting for the first-stage rocket to separate and fall into the sea, immediately rush over to salvage the wreckage.

In fact, as long as the rocket does not explode on the launch pad this time, even if it is not too bad, many problems can be found.

If the rocket can reach low-Earth orbit, it is basically a success, and if the simulated satellite can successfully separate in different orbits, it is a complete success.

Accompanied by the solemn rocket launch countdown.

"ignition!"

With a serious face, Zhang Xingyang calmly gave the rocket ignition command.

Among the propulsion system at the bottom of the rocket, the engines in the middle started to work first, and then the eight engines around them also started.

11 high-thrust engines consume hundreds of kilograms of fuel and oxidant within one second, converting them into a huge amount of high-temperature and high-pressure gas.

It turned into a blue flame, and guided it around through the diversion trough under the launching platform.

The powerful thrust of 1210 tons pushes hundreds of tons of rockets and slowly takes off from the ground.

Looking at the monitoring screen, the rocket pierced the sky at an extremely fast speed.

Everyone in the control center breathed a sigh of relief.

The fact that the rocket can fly means that there is no major problem with at least the most basic propulsion system and attitude adjustment system.

It also proves that the technical route of "Hongyan No. 1" can really go through.

This undoubtedly gave everyone a reassurance.

Everyone dealt with the rocket flight information sent back from radar monitoring stations in various places in an orderly manner.

Zhang Xingyang supported the console with both hands, staring at the various data constantly flowing on the big screen.

The brain was running crazily, calculating the current trajectory of the rocket.

And constantly revise the prediction model about the rocket's flight trajectory in his mind.

After a period of correction, the rocket's flight trajectory basically matches its own prediction model.

Zhang Xingyang came to the conclusion that there are certain problems in the angle adjustment of the swing engine of the propulsion system of the first stage rocket.

When the "Hongyan-1" rocket enters orbit, its height may be about 2% higher than the predetermined height.

But being able to achieve this level of accuracy is actually quite remarkable.

This kind of accuracy is like trying to hit the left hand of a fly with a gun at a distance of one thousand meters, but it hits the right hand instead.

It didn't hit exactly, but the result was the same, the flies died.

The same is true for the orbital height. It has no special impact if it is higher, and it is only a launch accident if it is lower.

And this is the result calculated completely according to the flight trajectory of the first-stage rocket. As long as the second-stage rocket is ignited and the angle is adjusted slightly, it can enter orbit with a nearly perfect posture.

"First stage rocket separated!"

"Ocean-Ocean 6 is monitoring the trajectory of the first-stage rocket!"

"The secondary rocket ignites successfully!"

As the good news came one after another, there were obviously more smiles on everyone's faces.

After the first-stage rocket is separated, the remaining fuel propels itself back to the intended ocean area.

This sea area has been designated as a military restricted area before the rocket is launched, and all ships except military salvage ships are prohibited from entering it.

For this reason, the navy also dispatched several warships to guard outside the restricted area.

Zhang Xingyang took Qin Ming and the others to make a control system with high sensitivity and precision.

The first-stage rocket landed slowly in the center of the restricted area.

Several salvage ships that had just arrived at the location saw a scene that they would never forget.

A huge pillar tens of meters long, with a ten-meter-long blue flame spraying out from below, set off huge waves several meters high on the sea surface, slapping their hulls non-stop.

Like the Dinghai God Needle in Journey to the West, it slowly fell vertically into the deep sea.

Wait until the huge waves on the sea that were just set off by the first-stage rocket subside a little.

Only then did several salvage ships drive to the place where the first-stage rocket entered the sea, and salvage work began.

——

After the secondary rocket is successfully ignited, push it against the fairing and push it to a position in low-Earth orbit.

"Secondary rocket separated successfully!"

In the control center of the Dongfeng launch site, another piece of good news was received from the radar monitoring station, which greatly inspired everyone in the control center.

The fairing starts to fly against the direction of the earth's rotation, releasing a simulated satellite inside every once in a while.

This launch test did not carry too many simulated satellites, only ten in total.

"Simulation Satellite 1, released successfully!"

"Monitoring the status of Analog Satellite 1!"

Now that the No. 1 satellite can be successfully released, the test launch is basically a complete success.

Because the ten satellites are the same, the first one succeeds, which means that the subsequent ones will basically succeed.

The chief who watched the test launch of the "Hongyan-1" rocket with Zhang Xingyang also had time to observe Zhang Xingyang who was still immersed in the release of the remaining satellites.

Zhang Xingyang looked a little thin, especially under the recent high-intensity work, he looked a little thin.

But when he was working, he could still feel the strength hidden under his thin body.

Sensing other people's eyes, Zhang Xingyang looked up and saw that it was the chief, so he smiled.

"What's the matter, chief?"

Zhang Xingyang knew that the other party was staring at him like this, and there was a high probability that he wanted to talk to him about something.

But the chief shook his head and said, "You should do the rocket launch first."

Seeing that the other party didn't seem to be very willing to express his intentions, Zhang Xingyang didn't care too much.

He turned his head and continued to look at the various data displayed on the large screen in front of the control center.

At this time, all ten simulated satellites have been released, and everyone is busy checking the operating status of the ten simulated satellites.

"Simulation Satellite 1, it is running normally!"

"Simulated Satellite 2, it is running normally!"

"Simulated Satellite 10, it is running normally!"

Accompanied by a series of news of normal operation, the test launch of the "Hongyan No. 1" rocket has been successfully completed.

After Zhang Xingyang announced the success of the "Hongyan No. 1" test launch mission, everyone immediately cheered.

In the control center, there was a burst of applause like a mountain roar and a tsunami!
