The huge robotic arm on the launch tower slowly loosens the connection to the rocket.

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

After all, the "Hongyan-1" launched this time is different from the various rocket models that were often launched before in all aspects.

Therefore, everyone has no bottom in their hearts, and they don't know whether this launch will be successful.

Since this is the first prototype rocket, there will be no verification of the recovery of the first stage rocket, and the first stage rocket will separate from the second stage rocket and crash into the East China Sea.

Before the start of the experiment, several sea salvage vessels 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 during this launch, even if it is not too much of a loss, many problems can be found.

If the rocket can reach low earth orbit, it is basically successful, and if the simulated satellite can successfully separate in different orbits, it is completely successful.

Accompanied by a solemn countdown to the launch of the rocket.

"Ignition!"

Zhang Xingyang, who had a serious face, calmly issued the rocket ignition command.

In the rocket's bottom propulsion system, several engines in the middle were the first to work, and then the eight surrounding engines also finished starting.

11 high-thrust engines consume hundreds of kilograms of fuel and oxidizer in one second, which is converted into a huge amount of high-temperature and high-pressure gas.

It turned into an azure flame and was directed around through the deflector under the launch pad.

A strong thrust of 1,210 tons propelled hundreds of tons of rockets to slowly take off from above the ground.

Looking at the surveillance footage, the rocket that pierced the sky at a very fast speed.

Everyone in the control center breathed a sigh of relief.

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

It also proves that the technical route of "Hongyan No. 1" can really be passed.

This undoubtedly gave everyone a reassurance.

Everyone methodically processed the rocket flight information sent back by radar monitoring stations in various places.

Zhang Xingyang propped his hands on the console, staring closely at the various data flowing on the big screen.

The brain was running wildly, calculating the rocket's current trajectory.

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

After a period of correction, the rocket's trajectory was basically consistent with its own prediction model.

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

When the "Hongyan-1" rocket enters orbit, the altitude may be about 2 percent higher than the predetermined altitude.

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

This level of accuracy is like trying to hit a fly in the left hand with a gun at a distance of a thousand meters, but then hitting the right hand.

Although it was not hit completely accurately, the result was all the same, the flies died.

The same is true for orbital altitude, a higher one does not have a particularly big impact, and only a lower one can be regarded as a launch accident.

Moreover, this is the result of completely calculating the flight trajectory of the first-stage rocket, as long as the second-stage rocket is ignited, and then the angle is slightly adjusted, it can be put into orbit with a near-perfect attitude.

"One-stage rocket separation!"

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

"The second stage rocket was successfully ignited!"

With the good news coming one after another, there was obviously a little more smile on everyone's faces.

After the first stage of the rocket is separated, the remaining fuel propels itself back into the predetermined ocean area.

The area was designated as a military exclusion zone before the rocket was launched, and all ships except military salvage boats were prohibited from entering it.

To this end, the navy has also dispatched several warships to guard outside the restricted area.

Zhang Xingyang took Qin Ming and the control system they made was very sensitive and accurate.

The first-stage rocket slowly descended in the center of the exclusion zone.

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

A giant pillar tens of meters long, with a dark blue flame more than ten meters long, erupted from below, setting off huge waves several meters high on the sea surface, constantly lapping against their hull.

It's like the Dinghai Divine Needle in Journey to the West, slowly falling vertically into the deep sea.

Wait until the huge waves that have just been lifted by the first-stage rocket on the surface of the sea have calmed down a little.

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

——

After the second stage rocket is successfully ignited, it is pushed to the position of low earth orbit with a fairing.

"The two-stage rocket was successfully separated!"

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

The fairing begins to fly in 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.

"Simulated Satellite 1, released successfully!"

"Analog Satellite 1 is being monitored!"

Since the No. 1 satellite can be successfully released, this test launch work can basically be regarded as a complete success.

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

The chief who watched the test launch of the "Hongyan No. 1" rocket with Zhang Xingyang also had the leisure to observe Zhang Xingyang, who was still immersed in the release of the remaining satellites.

Zhang Xingyang looks a little thin, especially under the recent high-intensity work, the whole person looks a little thin.

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

Feeling the gaze of others, Zhang Xingyang glanced up, found that it was the chief, and smiled.

"What's the matter with the 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 do a good job of launching the rocket first." ”

Seeing that the other party didn't seem to be very willing to say his intentions, Zhang Xingyang didn't care about anything.

Turn your head and continue 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 testing the operating status of ten simulated satellites.

"Simulated Satellite 1, operating normally!"

"Simulated Satellite 2, working normally!"

"Simulated Satellite 10, operating normally!"

Along with a series of news that it was operating normally, the test launch of the "Hongyan-1" rocket was a success.

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

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