Vol 4 Chapter 2371: amazing success

【Military Technology】【】
In a warm applause, Wu Hao ended his speech. Because this is a semi-public speech, Wu Hao is not easy to say too many things. If one accidentally says something controversial, it is likely to cause a storm.
This is also the place where they are very helpless. Most people want you to talk more, but there are many people who are staring at the content of your speech. If there is a little problem or controversy, it may be affected by these The person grabs it out, then renders it zoomed in.
As for the majority of the public, it is very easy to believe these contents that have been rendered, enlarged and processed, and instinctively denounce the attack together. When the victim really refuted the rumor, no one believed it, and no one even paid attention. That's why I don't have so many rumors on the Internet. Reasons why the cost of disinformation is too low and the cost of dispelling rumors is too high.
So this also makes people like Wu Hao more cautious in their speeches in public, and try not to involve some sensitive or controversial content.
At Zhou Xiangming's invitation, Wu Hao took a photo with all the staff in the hall, and Wu Hao's formation here was almost over.
After saying goodbye to everyone, he, accompanied by Yu Chengwu and Zhou Xiangming, came to the landing site in the middle of the Yatuhai Lake Basin. Before leaving, he wanted to see with his own eyes the Jianmu No. 2 core that successfully returned and landed. Secondary rocket.
By the time they arrived, there were actually quite a few technical staff at the scene. They need to inspect the reusable core two-stage rocket to assess its status and determine its safety.
This is mainly because the launch vehicle is filled with high-energy fuel. They are not fake rocket propellants, but they are also dangerous goods. Once it explodes, its power is really no less than a big bomb.
A reusable rocket like this requires the rocket engine to be ignited to generate thrust to decelerate the rocket during landing. So some of the fuel is stored in the rocket fuel tank.
In order to prevent some unexpected situations that may occur, the fuel in the rocket fuel tank is generally more than the mission design consumption standard, which is to prevent these unexpected situations.
Therefore, there is still some fuel left in the rocket body fuel tank of this rocket. This part of the fuel is likely to leak due to the rupture of the fuel tank body under the impact of the rocket landing.
The leaked fuel seeps out and volatilizes into the air, which is very dangerous. It is very likely to cause an explosion due to the static electricity on the clothes and hair of the on-site personnel, or the residual temperature on the engine after the engine is turned off.
In addition, there will also be some toxic substances, liquids, and gas leaks on the rocket body. If it is inhaled or contaminated, it is easy to be dangerous.
Therefore, after the rocket lands, special safety technicians need to come with professional equipment to conduct a physical examination on the rocket body to check whether the rocket is damaged, whether there is leakage of fuel or other liquids, whether the surrounding air is safe, and so on.
After these unsafe factors are eliminated and safety is confirmed, security technicians will allow other technicians and related personnel to come into close contact.
This also made Wu Hao and the others wait for a while at the periphery before they were allowed to enter the core area.

At this moment, the entire landing site has been isolated and protected, and there are security personnel standing nearby to maintain order on the scene and prevent miscellaneous people from approaching.
Seeing Wu Hao and the others arriving, the security guards immediately pulled away the isolation belt, and stood at attention with a standard military salute, and then stood up. These security personnel are all veterans. After they entered the security department, they still maintained the style of the army, and even the military salute was preserved.
Wu Hao nodded at the security guards and walked in.
At this moment, this reusable core two-stage rocket stands in front of him. The entire rocket body is lower than the core-stage rocket body. When the surface of the rocket passed through the atmosphere, it had been burnt to a blue-brown color, and some places had even been burned to a dark brown color.
The special heat-insulating material sprayed on the original arrow body is almost burned when it passes through the atmosphere. So the whole arrow body feels a little bumpy and uneven.
The flying wings in the middle of the arrow body have been retracted, and the two flying wings have also been burned and discolored, and it is difficult to see the color of the flying wings themselves. Below the rocket body is the landing frame. Compared with the thick landing frame of the first stage rocket, the landing frame of the core second stage rocket is much thinner. Even so, the strength is not much, but has increased.
This is also to deal with the impact force generated by the core two-stage rocket falling, and protect the rocket body structure from impact damage.
How is the state of the rocket now? Zhou Xiangming immediately asked a person in charge at the scene.
After hearing Zhou Xiangming's question, the person in charge immediately nodded at Wu Hao and the others with a smile and replied: "From the current preliminary inspection results, the entire arrow body is in good condition, and there is no obvious trauma or damage. .No signs of leaks of gas and liquid inside the rocket body were detected either.
It should be said that the return landing mission was a complete success~EbookFREE.me~ However, the specific results still need us to transport the rocket back to the laboratory of the Northwest Research Center for more systematic Accurate results can only be obtained after checking the test. "
Wu Hao, Zhou Xiangming and Yu Chengwu all laughed when they heard the person in charge so cautiously. If there is no problem with the current inspection, then there will be no major problems in the follow-up more detailed inspection.
So from this aspect, the success of this experiment is a certainty, which makes everyone happy again.
To be able to use such a short period of time to overcome a series of technical difficulties such as the re-entry of the secondary rocket into the atmosphere, the return to the landing and the landing, and the success of the experiment, this is really remarkable, and it is worthy of everyone's joy and pride.
Wu Hao looked at the surface of the rocket body, and then said to Yu Chengwu and the others with a smile: "The ablation on the surface of the rocket body is very uniform, which means that the rocket's flight attitude is very stable when it returns to the atmosphere. That's why it appears. This distinct two halves of color, the downward part, the burn is darker, and the upward part, the burn is lighter."
At present, our technology in flight control is relatively mature. Yu Chengwu nodded and said with a smile.

As for Zhou Xiangming, he followed Yu Chengwu's words and said with a smile: "Actually, the thermal insulation material sprayed on the arrow body is the same, so it can be either side.
We even thought about rotating the rocket during the flight, so that it can be heated evenly, so that one place will not be subjected to too high heat and force. "
