I built an armada - Chapter 643

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 there is almost no information in reality.

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

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

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

According to the conventional concept reached by the tribes of Blue Star in wind tunnel technology, the wind tunnels are classified according to their scale and function, usually divided 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 the subsonic wind tunnel, with a wind speed between 0 and 1 Mach. The third is the transonic wind tunnel, with a wind speed between 1 and 2 Mach. The fourth is the supersonic wind tunnel, with wind speeds between Mach 2 and 5. The last is the hypersonic wind tunnel, with wind speeds above Mach 5.

Currently, the supersonic wind tunnel is still being built and used. If you want to test hypersonic missiles, you must have a hypersonic wind tunnel.

The most advanced one on Blue Star is the fourth-generation supersonic wind tunnel. As for the speed of ballistic missiles exceeding Mach 10, it has nothing to do with the existence of a hypersonic wind tunnel.

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

According to the current progress, the key technology research of the fourth-generation hypersonic wind tunnel has become a top priority, because its appearance will greatly help the fourth-generation fighters, the test of hypersonic missiles, and many hypersonic spacecraft.

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

After muttering to himself, Su Dingping set his sights on the pile of information in his hand.

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

The flight trajectory of the hypersonic missile combines ballistic and gliding technology. That is to say, after the missile flies to a certain height, the booster separates and the missile enters the gliding stage, which can fly at low altitude in the atmosphere to avoid radar detection.

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

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

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

In this way, the hypersonic missile must be operated in a high orbit.

The higher the orbit, the thinner the atmosphere, the smaller the resistance, and the requirements for fuel and materials are reduced a lot, thereby reducing the difficulty of implementation.

Therefore, Su Dingping’s initial idea is to set the altitude at 80 to 120 kilometers.

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

In this way, he faces two choices in the design of the warhead, the first waverider warhead and the second double cone warhead.

At present, almost all ballistic missiles on the blue planet are cone warheads to reduce resistance. Of course, there are also double cone designs, in order to seek higher speed and strike force.

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

If you want to achieve hypersonic flight in the atmosphere, it is definitely not enough to rely on rocket engines alone, and ramjet engines must be ignited at a speed of more than Mach 1.8.

Because of the use of gliding warheads, it is necessary to glide at high speed in the atmosphere or at the edge of the atmosphere, which is commonly known as skipping stones, and it must also be able to maneuver.

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

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

However, in order to develop hypersonic missiles, this level cannot be skipped, and in the end he personally took action!

“The revolution has not yet succeeded, comrades still need to work hard!”

Su Dingping took a deep breath, abandoned all the distractions in his mind, and devoted himself 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 walked into the command building without stopping and convened an emergency meeting of the Navy’s senior management.

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

Sitting in the chief position, 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 is no result yet. So it is not clear what the situation is.”

“Of course, according to the relevant information currently obtained, their actions are very covert, and they should not go to the destination we speculated.”

Liu Huaming nodded lightly, and then asked: “Then where will they go?”

“Chief, it is not clear yet. An investigation has been carried out, and it will take some time.” Xiao Chongjun took over the conversation and said directly.

So far, none of them know what the situation is.

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

Sending naval fighters over, the legs are too short and they are of no use at all.

After a little contemplation, Liu Huaming said directly: “Let’s hurry up and investigate and find out the situation as soon as possible.”

“Notify everyone, and the whole army should be alert! This time the situation is unusual, I’m afraid the enemy is playing some crooked tricks on us!”

“Yes!”

Everyone responded very straightforwardly.

It is obvious that they have encountered a very difficult situation this time.

The Eagle Tribe and the East Wasteland Tribe joined forces and came with great momentum. Their intention to target the Longxia Tribe is very obvious. It is very likely that there is a huge conspiracy behind it.

Otherwise, these two tribes who are in collusion with each other would not have such an abnormal behavior.

Liu Huaming then asked: “How is the investigation of the Eagle Tribe going? They replaced the Enterprise with the Vulture, which is a lot of pressure for our navy.”

“Whether it is the Tomahawk cruise missile or the F18 fighter, 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 will arrive at the East Wilderness 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 troops we have left behind, I am afraid the pressure will increase.”

After hearing this, Liu Huaming fell into deep thought and frowned.

He knew very well that the current naval forces left behind could crush the surrounding small tribes, but the military pressure brought by the two aircraft carrier battle groups of the Eagle Tribe would be unprecedented.

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

“Report to the chief, there is a new situation in the East Wasteland Tribe.”

“According to the latest intelligence, the East Wasteland Tribe has secretly urgently transferred military, land, and construction experts. It is not clear what the specific mission is.”

Xu Dongguo took over the conversation and said, “Are they preparing to go to sea?”

“Report to the chief, it is not certain 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 was obviously different.

The new move of the East Wasteland Tribe this time, with so many experts gathered, must be for construction, which is completely different from before.

Reading the error-free version! 6=9+Shu_Bar released this novel for the first time.

Almost everyone’s brows were twisted, they could foresee that things were becoming more and more complicated, and the smell of conspiracy was getting stronger and stronger.

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

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

As for what these two countries were plotting, 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.

Obviously, the two countries have blocked the relevant news!

At the same time, the Navy Integrated Military Factory.

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

Various security equipment, even the ground-to-air missile forces, have also increased their combat readiness levels to respond to unexpected events at any time.

After receiving the news, Wanlong knocked on the door of Su Dingping’s office as soon as possible.

“Come in.”

After getting permission, Wanlong strode in.

“What do you want?”

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

“Report to President Su, the latest news came from the headquarters…”

Wan Long then reported all the matters.

After listening, Su Dingping fell into deep thought, and countless thoughts flashed through his mind.

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

Then there was only one possibility, with his arrival, the situation of Blue Star had been changed silently, and many things did not run according to the track of the previous life, but a new situation occurred.

This should be a new chain reaction, because the changes have produced different results!

Therefore, even he cannot predict what shady things the two colluding countries are planning, but one thing is certain, it is undoubtedly aimed at the Longxia tribe.

“Okay, I understand this, go and do your work.”

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

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

“Yes, I’ll do it right away.”

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

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

Su Dingping looked directly at Professor Zhang and asked.

“Reporting to Mr. Su, everything is going very smoothly. Dark Sword One does not require major adjustments. The relevant detailed adjustments, namely the cockpit layout, have been adjusted.”

Professor Zhang quickly and truthfully responded that the related technology of Dark Sword One has been frozen, there is no need to make major changes at all, and the losses in all aspects are within a reasonable range.

“That’s good.”

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

“Xie Zhenyu, there is an urgent mission next, and the level of danger is still very high. Do you have the courage to give it a try?”

When Xie Zhenyu heard this, he immediately puffed up his chest and responded solemnly: “Reporting to the chief, from the moment I joined the Air Force, I have been ready to sacrifice myself for the country.”

“I’ll take this task and ask for Mr. Su’s approval.”

“You are very confident. In fact, you don’t need to sacrifice.”

Su Dingping said without any hesitation, “The Eagle Tribe and the Eastern Wilderness Tribe are making some moves against us. I need you to fly Dark Sword One to investigate and obtain relevant information.”

“This is the specific route, please take a look.”

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

It covers the entire four native islands of the Donghuang Tribe, as well as the Aliu Islands and Haiyu Island and Weiwei Island belonging to the Longxia Tribe, in a straight line from north to south.

In this way, the scope of investigation is equivalent to covering the entire Donghuang tribe, and even going deep into the hinterland of the Donghuang tribe.

For the Longxia tribe, this is the first time that a reconnaissance plane has entered the sky above the Donghuang tribe.
