Chapter 640: The road is still long, and Dark Sword No. 1 is dispatched
It is also because the research and development of hypersonic missiles involves many technical problems that need to be overcome, and there is currently very little information on this aspect, which is almost non-existent in reality.
First of all, the limiting condition is a more advanced wind tunnel.
Obviously, the current third-generation wind tunnel technology is completely insufficient. It needs to be upgraded to a new generation and a fourth-generation wind tunnel center built!
However, the fourth-generation wind tunnel technology is still in the process of analysis and will take some time.
According to the agreed-upon concept of wind tunnel technology among the tribes of Blue Star, wind tunnels are classified according to their scale and functions, usually divided into low-speed wind tunnels, subsonic wind tunnels, transonic wind tunnels, supersonic wind tunnels and hypersonic wind tunnels. Wind tunnel and several other major categories.
The first is the low-speed wind tunnel, which is mainly used to test the aerodynamic characteristics of the aircraft during the take-off and landing stages. The wind speed is usually between 0-30 kilometers per hour.
The second is the subsonic wind tunnel, with wind speeds between 0 and Mach 1. The third is the transonic wind tunnel, with wind speeds between Mach 1 and 2. The fourth is the supersonic wind tunnel, with wind speeds between Mach 2 and Mach 5. Finally, there is the hypersonic wind tunnel, with wind speeds above Mach 5.
Currently, only supersonic wind tunnels are being built and used. If you want to test hypersonic missiles, you must have a hypersonic wind tunnel.
Currently, the most advanced thing 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 whether there is a hypersonic wind tunnel or not.
After all, the ballistic missile relies on the powerful output of the rocket engine to push it into outer space, and then re-enters the atmosphere to further increase its speed to such a high speed with the help of gravity acceleration.
According to the current progress, research on the key technologies of the fourth-generation hypersonic wind tunnel has become a top priority, because its emergence will provide opportunities for fourth-generation fighter jets, tests of hypersonic missiles, and many hypersonic flights. The spacecraft brings great help.
"The current speed of this missile has not exceeded Mach 5, but there is still enough time."
After muttering to himself, Su Dingping focused 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.
Hypersonic missile flight trajectories combine ballistic and gliding technologies. In other words, after the missile flies to a certain height, the booster separates, and the missile enters the gliding stage and can fly at low altitude in the atmosphere, thereby avoiding radar detection.
This design has a huge advantage. It can make hypersonic missiles more maneuverable and concealable, 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, if you want to break through Mach 4, the price you need to pay is very huge. Not only does it require more fuel, but the missile body also needs to be very large. This is completely unnecessary and very uneconomical from a combat perspective.
As a result, hypersonic missiles must operate in high orbits.
The higher the orbit, the thinner the atmosphere, the smaller the resistance, and the requirements for fuel and materials are reduced a lot, thus reducing the difficulty of implementation.
Therefore, Su Dingping's initial idea was to set the altitude at 80 to 120 kilometers.
At this altitude, it does not require much fuel and can also achieve hypersonic flight. This is completely different from the design concept of ballistic missiles. Naturally, there is no need to exceed 120 kilometers.
As a result, he was faced with two choices in the design of the warhead, the first waverider warhead, and the second biconical warhead.
Currently, almost all ballistic missiles on Blue Star have cone warheads to reduce resistance. Of course, there are also bi-cone designs in order to seek higher speed and strike 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 tackled.
To achieve hypersonic flight within the atmosphere, rocket engines alone are definitely not enough, and ramjet engines must operate at a speed exceeding Mach 1.8 to achieve ignition operation.
Due to the use of a gliding warhead, it needs to perform high-speed gliding flight within the atmosphere or at the edge of the atmosphere, which is commonly known as water drifting, 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, and they are the key points that need to be broken through! Of course, it is also a difficult point to break through, involving all aspects, such as materials science and so on.
At present, there is a huge gap between domestic materials science and foreign countries. 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 hurdle cannot be jumped. In the end, he had to take action himself!
"The revolution has not yet succeeded, comrades still need to work hard!"
Su Dingping took a deep breath, abandoned all the distracting thoughts in his heart, and devoted himself to researching new technologies, almost to the point of selflessness.
On the other side, the naval headquarters military base.
After Liu Huaming's special plane landed, he walked into the command building without stopping and held an emergency meeting of the navy's top brass.
Xu Dongguo, Qian Wenbing, 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 Aleu Islands for reconnaissance, but there are no results yet. So it is not clear what the situation is yet."
"Of course, according to the relevant information currently obtained, their actions are very covert, and they should not be going to the destination we speculated."
Liu Huaming nodded slightly and then asked: "Then where will they go?"
"Chief, it's not clear yet. An investigation has been carried out and it will take some time." Xiao Chongjun took over the conversation and said straightforwardly.
So far, none of them know what's going on.
Even if you want to use satellites for reconnaissance, the current resolution is still not very high, and the number is not enough to achieve real-time monitoring.
If HNA fighter jets are sent over, their legs are too short and of no use at all.
After thinking for a while, Liu Huaming said directly: "Let's seize the time to investigate and figure out the situation as soon as possible."
"If the notice continues, the whole army should be very alert! This situation is unusual. I'm afraid the enemy is playing some evil tricks on us!"
"Yes!"
Everyone responded simply.
It was clear that they had encountered something very difficult with this encounter.
The Eagle Tribe and the Donghuang Tribe have joined forces to attack the Longxia Tribe in a menacing manner. Their intention to target the Longxia Tribe is very obvious, and it is extremely possible that there is a huge conspiracy behind it.
Otherwise, these two collaborating tribes would not have behaved so abnormally.
Liu Huaming then asked: "How is the investigation on the Eagle Tribe going? They replaced the USS Enterprise with the USS Condor, which also puts a lot of pressure on our navy."
"Whether it is a Tomahawk cruise missile or an F18 fighter jet, they cannot be underestimated. We must be more vigilant."
Xu Dongguo glanced at the information in front of him and said, "Some news has come back. The Eagle Tribe garrison has begun to mobilize. According to intelligence speculation, it is estimated that the aircraft carrier Condor will arrive in the East Wasteland 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, I am afraid that the pressure will increase with the forces we have left."
After hearing this, Liu Huaming fell into deep thought and frowned.
He knew very well that the combat power of the naval force currently 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 moment, the door to the conference hall was suddenly pushed open, and Zhang Zhaoxin walked in in a hurry.
"Report to the leader, there is a new situation over there in the Eastern Barren Tribe."
"According to the latest intelligence, the Donghuang tribe secretly and urgently mobilized military, field, and construction experts. It is not yet clear what the specific tasks are."
Xu Dongguo took over the conversation and said: "Are they preparing to go to sea?"
"Reporting to the head, it is not certain yet. 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.
This new move of the Donghuang tribe, with so many experts gathered together, must be engaged in construction, which is completely different from before.

Almost everyone's brows were furrowed. They could sense that things were getting 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 Army are also actively participating.
The three armies of Long Xia could almost all foresee that, headed by the Eagle Tribe and supplemented by the Donghuang Tribe, a big conspiracy against the Long Xia Tribe was slowly beginning to unfold.
As for what these two collaborating countries are plotting, not only the Longxia tribe, but also the other tribes on Blue Star, and even the White Bear tribe, which has very powerful intelligence capabilities, are still unclear.
Obviously, these two countries have blocked relevant news!
At the same time, the Navy integrated arsenal.
The news also reached here from the Navy Headquarters. Wanlong immediately strengthened the alert deployment and built a tighter defense line. All security forces were involved and the vacation was cancelled.
Various security equipment, and even surface-to-air missile units, have also increased their combat readiness levels to respond to unexpected events.
After receiving the news, Wan Long immediately knocked on the door of Su Dingping's office.
"Come in."
After receiving permission, Wan Long strode in.
"What's the matter with you?"
Su Dingping put down the work at hand, raised his head and asked.
"Report to Mr. Su, the latest news came from the headquarters..."
Next, Wan Long reported on various matters.
After listening, Su Dingping fell into deep thought, with countless thoughts flashing through his head.
After pondering for a long time, he discovered that there seemed to be no such secret operation in his previous life.
Then there is only one possibility. With his arrival, the Blue Star pattern has been quietly changed. Many things have not continued on the same track as in the previous life, but a new situation has 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 ordered: "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, 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 have accepted this task and ask Mr. Su for 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, 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 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.
