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-1" launched this time is different in every aspect from the various rocket models that were frequently launched before.
Therefore, everyone has no idea 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 separates from the second-stage rocket, it will control itself to fall into the East China Sea.
Before the experiment began, several salvage ships were on standby at sea.
Just waiting for the first stage rocket to separate and fall into the sea, we immediately rushed over to salvage the wreckage.
In fact, as long as the rocket does not explode on the launch pad during this launch, many problems can be found even if it is not a huge loss.
If the rocket can reach low-Earth orbit, it is basically a success. If the simulated satellites can successfully separate in different orbits, it is a complete success.
Accompanied by the solemn countdown to rocket launch.
"ignition!"
With a serious look on his face, Zhang Xingyang calmly issued the rocket ignition command.
Among the propulsion systems at the bottom of the rocket, the engines in the middle started working first, and then the eight engines around them also completed their startup.
11 high-thrust engines consume hundreds of kilograms of fuel and oxidizer in one second, converting into a huge amount of high-temperature and high-pressure gas.
It turns into a blue flame and is directed around through the diversion trough under the launch pad.
The powerful thrust of 1,210 tons pushes the rocket of hundreds of tons to slowly take off from the ground.
Looking at the surveillance screen, the rocket streaked across the sky at extremely fast speeds.
Everyone in the control center breathed a sigh of relief.
If the rocket can fly, it means that there are no major problems with the most basic propulsion system and attitude adjustment system.
It also proves that the technical route of "Hongyan No. 1" can truly be achieved.
This undoubtedly gave everyone reassurance.
Everyone is processing the rocket flight information sent back by radar monitoring stations in various places in an orderly manner.
Zhang Xingyang supported the console with both hands, staring closely at the various data flowing on the big screen.
The brain was running wildly, calculating the rocket's current flight path.
And constantly revise the prediction model about the rocket flight trajectory in his mind.
After a period of correction, the rocket's flight 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 first-stage rocket's propulsion system.
When the "Hongyan-1" rocket enters orbit, the altitude may be about 2% higher than the intended altitude.
But being able to achieve this level of accuracy is actually quite remarkable.
This kind of accuracy is like trying to hit a fly's left hand with a gun at a distance of one thousand meters, but hitting the right hand instead.
Although the hit was not completely accurate, the result was the same, the flies were all dead.
The same is true for the orbital altitude. A higher altitude does not have a particularly big impact. Only a lower altitude can be considered a launch accident.
And this is a result calculated completely based on the flight trajectory of the first-stage rocket. As long as the second-stage rocket is slightly adjusted in angle when igniting, it can enter the orbit in an almost perfect attitude.
"First stage rocket separates!"
"Osanyang 6 is monitoring the trajectory of the first-stage rocket!"
"The second-stage rocket ignited successfully!"
With the news of good news, everyone's faces were obviously more smiling.
After the first-stage rocket separates, the remaining fuel propels itself back to the predetermined ocean area.
This area of sea had been designated as a military restricted area before the rocket was launched, and all ships except military salvage ships were prohibited from entering it.
To this end, the navy also dispatched several warships to provide security outside the restricted area.
The control system created by Zhang Xingyang, Qin Ming and others is very sensitive and precise.
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 they would never forget.
A huge pillar tens of meters long, with ten meters of blue flames ejected from the bottom, set off huge waves several meters high on the sea, constantly beating their hull.
Just like the sea-fixing needle in Journey to the West, it slowly fell vertically into the deep sea.
By the time the huge waves on the sea had just been set off by the first-stage rocket, they had calmed down a little.
Several salvage ships then drove 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 against the fairing and pushed to a low-Earth orbit position.
"The second-stage rocket separated successfully!"
In the Dongfeng Launch Site Control Center, another piece of good news was received from the radar monitoring station, which greatly inspired everyone in the control center.
The fairing began 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.
"Simulated Satellite 1, released successfully!"
"Monitoring the status of Analog Satellite 1!"
Since Satellite No. 1 can be successfully released, this test launch is basically considered a complete success.
Because the ten satellites are the same, if the first one succeeds, it means that the subsequent ones will basically succeed.
The leader 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 looks a little thin, especially under the recent high-intensity work, the whole person looks a little thin.
But while working, you can still feel the power hidden under his thin body.
Feeling the eyes of others, Zhang Xingyang looked up and smiled when he saw that it was the chief.
"What's wrong, chief?"
Zhang Xingyang knew that the other person 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 reveal his intentions, Zhang Xingyang didn't care much.
He turned around 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 testing the operating status of the ten simulated satellites.
"Simulated Satellite 1, operating normally!"
"Analogue Satellite 2, operating normally!"
"Simulated satellite No. 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 that the "Hongyan-1" test launch mission was successful, everyone cheered instantly.
In the control center, there was a round of applause like a mountain roaring and a tsunami!
