I built an armada.

Chapter 640: The road is long but we still move forward, dispatching Dark Sword No.

Another reason is that the research and development of hypersonic missiles involves many technical difficulties that need to be overcome, and there is very little information available in this regard, and almost no information in reality.

First of all, the limiting condition is a more advanced wind tunnel.

It is obvious that the third-generation wind tunnel technology currently available is completely insufficient and needs to be upgraded to the new generation and a fourth-generation wind tunnel center needs to be built!

However, the fourth-generation wind tunnel technology is still in the process of analysis and will take some time.

According to the commonly accepted concepts reached by the tribes on Blue Star regarding wind tunnel technology, wind tunnels are classified according to their size and function, usually into several main categories, such as low-speed wind tunnels, subsonic wind tunnels, transonic wind tunnels, supersonic wind tunnels and hypersonic wind tunnels.

The first is the low-speed wind tunnel, which is mainly used to test the aerodynamic characteristics of the aircraft during takeoff and landing. The wind speed is usually between 0-30 kilometers per hour.

The second is a subsonic wind tunnel, with wind speeds between Mach 0 and 1. The third is a transonic wind tunnel, with wind speeds between Mach 1 and 2. The fourth is a supersonic wind tunnel, with wind speeds between Mach 2 and 5. Finally, there is a hypersonic wind tunnel, with wind speeds above Mach 5.

What is currently being built and used are supersonic wind tunnels. If you want to test hypersonic missiles, you must have a hypersonic wind tunnel.

Currently, the most advanced equipment on the blue planet is the fourth-generation supersonic wind tunnel. As for the speed of ballistic missiles exceeding Mach 10, it has nothing to do with whether there is a hypersonic wind tunnel or not.

After all, ballistic missiles rely on the powerful output of rocket engines to be pushed into outer space, and then enter the atmosphere to further increase their speed with the help of gravity acceleration to reach such a high speed.

According to the current progress, the key technology research and development of the fourth-generation hypersonic wind tunnel has become a top priority, because its appearance will bring great help to the testing of fourth-generation fighter jets, hypersonic missiles, and many hypersonic flying spacecraft.

"The current speed of this missile has not yet exceeded Mach 5, but there is still time."

After muttering to himself, Su Dingping turned his attention to the pile of information in his hand.

In the data sketch, he has drawn out the flight trajectory of the hypersonic missile, which is obviously not a ballistic flight mode.

The flight trajectory of a hypersonic missile combines ballistic and gliding technologies. That is, after the missile reaches a certain altitude, the booster separates and the missile enters the gliding phase, flying at low altitudes in the atmosphere to avoid radar detection.

This design has a huge advantage, which is that it can make hypersonic missiles more maneuverable and concealed, making it very difficult for the enemy to intercept them.

This is a completely different flight trajectory from that of ordinary missiles, and it is also the biggest difference from ordinary missiles.

In low-altitude flight, the cost of breaking Mach 4 is very huge. Not only does it require more fuel, but the missile body also needs to be made very large, which is completely unnecessary and very uneconomical from a combat perspective.

In this case, hypersonic missiles must be operating in high orbits.

The higher the orbit, the thinner the atmosphere, the smaller the resistance will naturally be, and the requirements for fuel and materials will be reduced a lot, thus reducing the difficulty of implementation.

Therefore, Su Dingping's initial idea was to set the altitude between 80 and 120 kilometers.

At this altitude, not much fuel is needed, and hypersonic flight can be achieved. This is completely different from the design concept of ballistic missiles, so there is naturally no need to exceed 120 kilometers.

As a result, he faced two choices in the design of the warhead: the first was the waverider warhead, and the second was the double-cone warhead.

Currently, almost all ballistic missiles on the blue planet have conical warheads to reduce resistance. Of course, there are also double-cone designs in order to seek higher speeds and striking power.

In addition to the difficulty in building a hypersonic wind tunnel center, hypersonic missiles still have many difficulties to overcome, such as the ramjet engine technology that is currently being researched.

If you want to achieve hypersonic flight in the atmosphere, rocket engines alone are definitely not enough, and ramjet engines must be ignited and operate at speeds exceeding Mach 1.8.

Since a gliding warhead is used, it is necessary to perform high-speed gliding flight within the atmosphere or at the edge of the atmosphere, commonly known as skipping stones, and it must also be able to maneuver.

Therefore, the requirements for the warhead's aerodynamic layout, control technology, and heat protection and insulation technology are very high, which is the key point that needs to be broken through! Of course, it is also the difficulty of breaking through, involving all aspects, such as material science and so on.

At present, there is a huge gap between China and foreign countries in materials science. It is almost impossible to achieve a breakthrough in the short term unless Su Dingping personally participates.

However, in order to develop a hypersonic missile, this hurdle cannot be skipped, and in the end he has to take action personally!

"The revolution has not yet succeeded, comrades, we still need to work hard!"

Su Dingping took a deep breath, put aside all the distracting thoughts in his mind, and devoted his full attention to the research and development of new technologies, almost reaching a state of selflessness.

On the other side, the Navy Headquarters military base.

After Liu Huaming's special plane landed, he immediately went into the command building and convened an emergency meeting of the navy's top leaders.

Xu Dongguo, Qian Wenbing, Xiao Chongjun and others all attended the meeting.

Sitting in the chief seat, Liu Huaming asked directly: "What is the situation now?"

Xu Dongguo on the side quickly responded: "We have sent warships to the Aleutian Islands for reconnaissance, but there are no results yet. So it is not clear what the situation is at the moment."

"Of course, according to the information we have obtained so far, their actions are very covert. They should not be going to the destination we speculated."

Liu Huaming nodded slightly, and then asked: "Where will they go?"

"Chief, it's not clear at the moment. We've already started an investigation, and it will take some time." Xiao Chongjun took over the conversation and said directly.

So far, none of them have a clear idea of ​​what is going on.

Even if we want to use satellites for reconnaissance, the current resolution is still not high enough, and the number is not enough, so real-time monitoring is not possible.

If we send naval aviation fighter jets over there, their legs are too short to be of any use at all.

After a brief moment of contemplation, Liu Huaming said directly: "Let's hurry up and investigate and find out the situation as soon as possible."

"Notify the whole army to be on high alert! This time the situation is unusual, I'm afraid the enemy is playing some tricks on us!"

"Yes!"

Everyone responded straightforwardly.

It was obvious that they had encountered something very difficult this time.

The Eagle Tribe and the East Wasteland Tribe have joined forces and are coming with great force. Their intentions against the Longxia Tribe are very obvious, and it is very likely that there is a huge conspiracy behind this.

Otherwise, these two tribes, which are in cahoots with each other, would not have behaved so abnormally.

Liu Huaming then asked, "How is the investigation of the Eagle Tribe going? They replaced the Enterprise aircraft carrier with the Vulture, which is also a lot of pressure for our navy."

"Whether it's a Tomahawk cruise missile or an F18 fighter jet, they should not be underestimated. We must be vigilant."

Xu Dongguo glanced at the information in front of him and said, "Some news has been reported that the Eagle Tribe garrison has begun to mobilize. According to intelligence speculation, it is estimated that the Vulture aircraft carrier will arrive at the East Desert Tribe in one day." "If there is only one nuclear-powered aircraft carrier fleet, we can still withstand the pressure. But if we add another one, with the current forces we have left behind, I am afraid the pressure will increase."

Hearing this, Liu Huaming fell into deep thought and his brows furrowed.

He was very clear about the current naval forces that remained. Although their combat effectiveness could crush those small tribes around them, the military pressure brought by the two aircraft carrier battle groups of the Eagle Tribe would be unprecedented.

At this moment, the door of the conference hall was suddenly pushed open, and Zhang Zhaoxin walked in hurriedly.

"Report to the Chief, there is new information from the East Wasteland Tribe."

"According to the latest intelligence, the East Wasteland Tribe has secretly and urgently mobilized experts in military, geography, and architecture. It is not clear what their specific mission is at the moment."

Xu Dongguo took over the conversation and asked, "Are they preparing to go out to sea?"

"Reporting to the commander, it is still uncertain at the moment. But according to speculation, their destination does not seem to be an island."

Zhang Zhaoxin's response immediately made the entire conference hall quiet, and the atmosphere became noticeably different.

The new move of the Donghuang tribe this time, which has gathered so many experts, must be for construction, which is completely different from before.

Almost everyone had a frown on their face. They could sense that things were becoming increasingly complicated, and that the smell of conspiracy was becoming stronger and stronger.

Of course, in addition to the navy making relevant preparations, the air force and the army are also actively participating.

Almost all the three armies of Longxia could sense that a huge conspiracy against the Longxia tribe, led by the Eagle tribe and supplemented by the Donghuang tribe, was slowly unfolding.

As for what these two colluding countries are planning, not only the Longxia tribe, but also the other tribes on the blue planet, even the White Bear tribe with very strong intelligence capabilities, are still unclear.

It is obvious that these two countries have blocked the relevant news!
At the same time, the Navy integrated arsenal.

The news also reached here from the Navy Headquarters. Wanlong immediately strengthened the vigilance deployment and built a tighter defense line. All security forces were involved and their vacations were cancelled.

Various security equipment, and even surface-to-air missile units, have increased their combat readiness levels to be ready for any unexpected events.

After receiving the news, Wan Long knocked on Su Dingping's office door immediately.

"Come in."

After getting permission, Wanlong strode in.

"What's the matter with you?"

Su Dingping put down the work at hand, looked up and asked.

"Reporting to President Su, the latest news came from the headquarters..."

Next, Wanlong reported on various matters.

After listening, Su Dingping fell into deep thought, with countless thoughts flashing through his mind.

After pondering for a while, he found that there seemed to be no such secret operation in his previous life.

Then there is only one possibility. With his arrival, the structure of Blue Star has changed silently. Many things are not running along the same track as in the previous life, but a new situation has emerged.

This should be a new chain reaction, producing different results due to changes!

Therefore, even he could not predict what shameful things the two colluding countries were planning, but one thing was certain, they were undoubtedly targeting the Longxia tribe.

"Okay, I know about this, go ahead and do your work."

After receiving the order, Wan Long turned around and walked out of the office.

But before he could even reach the door, Su Dingping called him back and ordered, "Contact Professor Zhang and ask him and Xie Zhenyu to come over immediately."

"Yes, I'll do it right away."

Wan Long hurried out, and not long after, he brought back Professor Zhang and Xie Zhenyu.

"Did you find any problems in your follow-up research?"

Su Dingping looked directly at Professor Zhang and asked.

"Reporting to President Su, everything is going very smoothly. Dark Sword One does not require major adjustments. The relevant details, that is, the cockpit layout, have been adjusted."

Professor Zhang quickly responded truthfully, saying that the relevant technology for Dark Sword No. 1 had been frozen and there was no need for major changes, and the losses in all aspects were within a reasonable range.

"That's good."

Su Dingping glanced at the relevant information submitted by Professor Zhang, a look of satisfaction appeared on his face, and then he looked at Xie Zhenyu.

"Xie Zhenyu, there is an urgent mission next. It is very dangerous. Do you have the courage to try it?"

Hearing this, Xie Zhenyu immediately puffed out his chest and responded solemnly: "Commander, since the moment I joined the Air Force, I have been ready to sacrifice myself for the country."

"I accept this task. Please approve it, Mr. Su."

"Very confident, but actually you don't need to sacrifice anything."

Su Dingping said directly without any hesitation, "The Eagle Tribe and the East Wasteland Tribe are taking some actions against us. I need you to drive the Dark Sword No. 1 to investigate and obtain relevant intelligence."

"This is the specific route, take a look."

Su Dingping then took out the route map he had just drawn and personally pointed it out to Xie Zhenyu.

It covers the four mainland islands of the Donghuang tribe, as well as the Aleutian Islands and the Haiyu Island and Weiba Island belonging to the Longxia tribe, stretching from north to south.

In this way, the scope of reconnaissance covers the entire Donghuang tribe, and even penetrates into the heart of the Donghuang tribe.

For the Longxia tribe, this was the first time a reconnaissance plane entered the airspace over the Donghuang tribe’s homeland.
