The plane roared and tore through the air and rushed into the sky, leaving the ground tumbling turbulent.

At this time, there was still the slightest coquettishness in Hua Baixiang's eyes, and some had a serious and dignified look.

Hua Baixiang is very clear about his position: although he likes Zhang Hao, he is the left protector of the Tiandu faction! Here in the Tiandu faction, with the left as the respect, it can be said that Hua Baixiang is a veritable peak ruling class of the Tiandu faction. Therefore, Hua Baixiang is very clear about her responsibilities.

Seducing Zhang Hao has many purposes, that is, for the wealth and technology of Dayang Group. Of course, it cannot be denied that I do like Zhang Hao.

But at this time, Hua Baixiang looked at the No. 1 prototype that rushed into the sky like lightning, but there was an indescribable shock in her heart. There were no spells, no formations, and they completely relied on the power of machinery to rush into the sky, and the speed was so fast.

In the blink of an eye, the plane became a black dot.

Now Hua Baixiang has also begun to come into contact with a lot of technology, and she now knows the meaning of technology very well!

In the past, we didn't have the current science and technology, and most of the time we relied on experience and instinct to design products (magic weapons), and then under the effect of spells and formations, the magic weapons had strong abilities.

But after having the technology, I looked back at the magic weapons of the past, etc., and found that because of the unreasonable design, the power of the formation and spell could only be exerted half, or even lower.

The magic weapon designed by Dayang Group, because the design is reasonable, can give full play to the power of the formation, ninety, or even more.

If you calculate the rationality of the magic weapon itself, the power of the magic weapon of Dayang Group is generally increased by three times!

The magic weapon price of Dayang Group is only about 1.5 times the price of the general magic weapon, and there is a perfect after-sales system. This is also one of the reasons why the products of Dayang Group are so popular.

However, looking at the plane soaring into the sky right now, Hua Baixiang's heart is becoming more and more solemn - the technology of Dayang Group seems to be undergoing a qualitative change!

She didn't know the technical situation within the Dayang Group, even if she almost gave herself up, her whole body was touched by Zhang Hao, and Zhang Hao didn't reveal any technical details, but some technical 'results', Zhang Hao didn't mind disclosing them.

I have seen a lot of these technical results, and Hua Baixiang has slowly gained her own insight. Since the steel battleship, there seems to be no technology that makes Zhang Haoneng always talk about it.

Until、Airplanes appeared!

When the propeller aircraft came out last year, Dayang Group promoted it, but at that time, many people felt that the propeller aircraft was a toy and an expensive toy.

However, because the price is quite reasonable, and everyone wants to know more or less about the technical situation of the Ocean Group, there are still a lot of orders for the aircraft, but there are not many.

Hua Baixiang has also personally piloted that kind of ordinary propeller plane, and there is nothing brilliant about it. In addition, it can leap above the aura layer and be used as a reconnaissance aircraft.

But the war that has occurred in recent days has given everyone a new understanding of airplanes - in the face of the sudden appearance of the sky city in the east, it turns out that only airplanes, a toy that everyone used to see, can have a certain impact.

There is no doubt about the power of the castle in the sky. It was simply a fairy city that came to earth. But this is such a fairy city, but there is nothing to be done in the face of the fragile plane flying above the aura layer!

Neither a master nor a crossbow can reach the height of an airplane.

There is only one weapon that can, and that is still the product of the Ocean Group, the second-generation Thunder Cannon. Castle in the Sky used captured Thunder Cannons and Shotgun shells to have a chance to shoot down the plane, but there were still not many.

Hua Baixiang was still stunned, but she heard the person in charge of the radio station next to her talking, and after a while, a voice came from the microphone.

Hua Baixiang was very sensitive, and immediately looked over and found that it turned out to be a completely new telegraph technology: instead of a rudimentary binary password, it was a direct call!

Yes, radio talk! The technology of the Ocean Group has gone one step further -- this is the product of the progress of computer technology. Dayang Group's computer technology has entered the final stage of experimentation!

Hua Baixiang was surprised at this time, turned her head to look at Zhang Hao, but found that Zhang Hao was already in the distance, at the No. 2 prototype, talking to the researchers.

Hua Baixiang immediately listened attentively, but heard everything, apparently shielded. 'Hmph!' Hua Baixiang snorted lightly, and could only honestly observe the current No. 1 aircraft test. The technician who listened to the test kept giving all kinds of commands, what stall test, roll, dive, rapid circle, etc.

In the sky, there was a roar from the airplane test, which made Hua Baixiang feel a power that she had never experienced before.

What makes Hua Baixiang even more dignified is that this new jet plane is much more flexible than the propeller plane, and the propeller plane is more flexible than the flying boat.

Next to him, Zhang Hao gently stroked the ballistic missile above his head, his eyes were a little intoxicated.

This ballistic missile technology was studied in conjunction with jet aircraft. In the process of research, Zhang Hao opened a lot of gold fingers. Of course, Zhang Hao doesn't know the specific technology, but at least Zhang Hao knows the general technical direction.

For example, metallic hydrogen substances that are constantly compressed and finally compressed to the limit. Not counting combustion, the energy contained in the compression of metallic hydrogen is 30 times that of the same volume of gold explosives! If you count the power of hydrogen combustion explosion, it can be doubled.

"What is the yield of this metallic hydro-oxygen bomb?"

"Mr. Zhang, the current production line has been adjusted, and the current daily output is 10. It is expected that the production capacity will increase by 50% in the later period. ”

"10 ...... a day" Zhang Hao groaned a little, the number was a little small, too little, but he still gave encouragement to the scientific research staff, "Yes, continue to work hard and build a second production line as soon as possible." The next batch of 600 million high-grade spirit stones is coming soon. ”

"600 million?" exclaimed the scientific researchers, who had previously researched aircraft, and the largest one-time allocation was only 300 million.

Zhang Hao said with a smile: "The war in the east made everyone see the advantages of aircraft for the first time. So, this time the allocation has increased quite a bit.

However, of these 600 million high-grade spirit stones, 200 million are specifically used to study ballistic missiles, especially super ballistic ballistics that are super large and can be launched from the ground!"

After that, Zhang Hao added in his heart: It would be better if the rocket could be developed.

Thinking like this, Zhang Hao looked up at the deep sky. The actual gravity of this world is beyond imagination, and the thickness of the atmosphere is even greater than the limit.

At present, according to the test and calculation results of the hydrogen balloon, scientists of the Ocean Group have come to the conclusion that the thickness of the atmosphere is about 1,000 kilometers - and the atmosphere on the earth, if Zhang Hao remembers well, should only be 80~85 kilometers (middle layer); Beyond this height, the air can be ignored.

The extreme gravity and the super-thick atmosphere have become a huge drag on spaceflight. Ordinary chemical fuel, simply not enough to send a rocket into near-earth orbit.

According to the calculations of the scientists of the Ocean Group, the metal hydrogen exceeds the gravitational limit by more than double, that is to say, one kilogram of metal hydrogen can theoretically send one kilogram of items into low earth orbit.

However, rocket research has only been put on record at the core of the Dayang Group, and it will be planned only after the computer technology is mature and the supersonic aircraft are mass-produced. At present, there are many research projects of Dayang Group.

Zhang Hao talked to the researchers for a while, and someone came over to invite: the plane is about to enter the supersonic test.

Zhang Hao immediately returned to the radio station, didn't look at Hua Baixiang's charming eyes, and went directly to work. The angry flower Baixiang rolled her eyes - it seems that there is still a long way to go to completely master this little man.

After Zhang Hao returned to the station, the station immediately ordered: "Start the supersonic test! Pay attention to safety, and stop the test as soon as you can't do anything!"

"Roger!"

The radio echoed, and then fell silent.

Only a low roar could be heard in the sky.

But by this time the roar was approaching. Flower Baixiang frowned, and she looked up, her eyes sparkling from the use of spells. With the help of the spell, Hua Baixiang saw the black dots in the sky, and also saw clearly that the black dots seemed to be speeding up, speeding up.

At a certain moment, the voice came from the radio again: the speed has reached the limit, and supersonic speed is coming!

A few seconds later, Hua Baixiang saw a sudden white cloud around the plane, and the cloud and mist actually surrounded the plane, showing a cone shape, which was very beautiful.

Before Hua Baixiang could figure out what this phenomenon was, an explosion suddenly erupted between heaven and earth. The voice was crisp, low and powerful, as if the space had been torn apart.

Accompanied by the sound of an explosion, the roar of the plane was heard like the waves of the ocean.

At this time, the plane in the sky, like a bird free from the shackles, began to pursue that extreme freedom.

"1.1 times the speed of sound, the aircraft is normal, jitter is 25% of the design range!"

"At 1.05 times the speed of sound, the jitter stabilized and was 7% in the design range; ”

"1.3 times the speed of sound...... 1.5 times the speed of sound...... 1.7 times the speed of sound ......"

"2.0 times the speed of sound! The aircraft jitter is 32% of the design range, and the application continues to accelerate. ”

"No. 1, pause acceleration!" Lin Yinghao, the chief designer of the aircraft, said, "Maintain 2.0 times the speed of sound for half an hour and conduct extreme tests." Pay attention to the aircraft engine temperature. ”

"Received on the 1st. ”

The plane entered the test again, first making small turns, etc., and then began to increase maneuvering maneuvers, starting to roll, fly sideways, dive, pull up, and sprint upward.

In the end, the test was no problem, and the speed was reduced to subsonic speed again, and the test was carried out above the aura layer.

Above the aura layer, due to the lack of aura assistance, the planet's huge gravitational pull began to play tricks, making the aircraft test full of challenges.

The heavy gravity makes it slightly difficult for the plane to accelerate. Although acceleration is only related to mass, in the actual test, gravity still has an effect – a resultant force is formed.

Compared to the test below the Reiki layer, the test above the Reiki layer is a lot more troublesome and careful.

Fortunately, after several years of accumulation, the test was still a complete success.

Then there's the ceiling test. The ceiling test cannot be tested in the wind tunnel test, and can only be tested in practice. The plane first sprinted at subsonic speed, and in one fell swoop it actually sprinted to an altitude of 500 kilometers!

At this height, even Zhang Hao was surprised. But I soon figured it out - the atmosphere of this world is thick, and the scientists of the Ocean Group tested that it is 1,000 kilometers at an altitude, and the plane can only fly 500 kilometers, which is considered low.

This is also because of the high gravitational force, the aircraft needs more buoyancy to work. And after 500 kilometers in the air, the buoyancy of the air is already insufficient.

But then hypersonic tests continued. In a supersonic environment, the plane sprinted to the limit of 600 kilometers. Moreover, the high-altitude air is thin, and the plane has completely relied on mechanical power without the assistance of the formation, reaching the supersonic speed limit of 3.2 times! (In fact, the formation above the aura layer cannot be activated.) ）

Such a speed is due to the fact that the whole body of the aircraft is made of spiritual materials, and the fuel is 'refined naphtha'.

Finally, the aircraft undergoes an extreme test: near-flight!

The plane was only 100 meters above the ground, swept at supersonic speed, and then skimmed over the sea, the shock wave caused by the plane shattered the ground, broke the grass and trees, and a deep trench dozens of kilometers long appeared directly on the sea, and the waves rolled wildly.

The plane took more than four hours to test, and it was not until 13 o'clock in the afternoon that it finally landed on the ground.

When the white plane stopped, Hua Baixiang looked at the fighter in front of her in amazement, which was about 25 meters long.

This fighter had just not opened the formation at all. What happens if you open a formation?

Hua Baixiang was still stunned, but Zhang Hao came to Hua Baixiang: "Let's go, I'll take you for a ride." We piloted prototype No. 2 and fired live ammunition. ”

"Live fire?"

How to shoot?

Hua Baixiang suddenly glanced at Zhang Hao: Little man, what do you mean by this?
