After the engineer finished speaking, he took a breath of cold air.

Although the principle has been explained, the technology and design behind the principle are very complicated. It can be said that it is a very complicated task to compress and eject nitrogen as a coolant and also provide power to the aircraft.

Research.

In addition, I had never thought of such a method before.

If it is a rocket engine, whether it is solid fuel or liquid fuel, the most important thing is high-pressure combustion and then eruption. And the anti-gravity aircraft certainly cannot burn inside, so the compression fan blades must be redesigned to compress the used nitrogen step by step.

Discharge again.

The technology contained in it is too complex and high-end.

When many people had no time to express their emotions, the Airship II type flew straight into the clouds and then disappeared from sight. Their emotions suddenly changed to, "The climb is too fast!"

“It’s amazing!”

"This should be much faster than the climbing speed of ordinary fighter jets, right?"

This is natural.

Anti-gravity aircraft climb much faster than ordinary aircraft. Generally, the climbing inclination angle of ordinary aircraft cannot exceed 25 degrees. There is no clear regulation for fighter jets, but the normal flight inclination angle will not exceed 40 degrees. Anti-gravity aircraft climb normally, four

Fifteen degrees of inclination are normal operations.

After the aircraft disappeared from sight, the reporters could only continue to wait.

The only information they can know is what kind of tests the aircraft is doing.

Soon, they also got the information.

The aircraft is preparing for a supersonic cruise test. The supersonic cruise test includes two parts, one is entering supersonic speed, and the other is continuous cruise.

Because the test is conducted at an altitude of 10,000 meters, it is naturally invisible to the eyes, and it is impossible for cameras on the ground to see it. Only accompanying aircraft, radar, and satellites can see it.

Reporters can only continue to wait.

Wang Hao and others also returned to the control room, keeping an eye on the status of Airship-2.

The pilot is always in contact and will report the situation every once in a while.

Radar systems are also keeping track.

soon.

Kongjian-2 climbed to a height of more than 10,000 meters and was in the extended phase of acceleration. The acceleration was still very fast. After a short period of time, I heard a report saying that it had exceeded the speed of sound.

"Speed, 346."

"Speed, 367, detect power!"

"..."

After Kongjian-2 broke through the speed of sound, the acceleration test continued. The ultimate goal was to turn on the superconducting motor at 80% of its maximum power and calculate the instant speed. The follow-up was to maintain the speed and cruise.

This chapter is not over yet, please click on the next page to continue reading! In terms of performance theory, at an altitude of 10,000 meters, after turning on 80% power, the maximum speed is about 420 meters/second, but the test and theoretical data are

Different, the final speed reached 442 meters/second, which is about Mach 1.3, and the speed almost reached the moment of maximum resistance.

Then there is no need to continue to increase the speed, but start normal supersonic cruising.

This is the capability that anti-gravity aircraft needs to possess.

The reporters also got the news that the aircraft entered the supersonic cruise stage. Since nothing could be seen at the scene, they could only wait for the news. After entering the supersonic cruise, they only needed to make records and wait for the next stage of testing.

alright.

Generally speaking, the supersonic cruise test of a fighter jet will not take more than ten minutes.

But they waited for more than 20 minutes and still did not receive the information about the next stage. They immediately asked the person in charge of the interview area, "Why hasn't the next stage started yet? Is the supersonic cruise not over yet?"

Half an hour later, a foreign reporter even asked directly, "Did you encounter any problems?"

Many people also talked about it.

The person in charge hesitated for a moment, then called his superiors and got an answer that revealed the cruise information.

Only then did he clearly reply to reporters, "The supersonic cruise test time is one hour."

"One hour?"

"Are you kidding me?"

Many reporters were stunned.

Even high-end fighter jets that have been completed and in service can only cruise at supersonic speeds for about half an hour.

One reporter couldn't help but ask, "Aren't Kongjian-2 worried about energy issues?"

This question immediately attracted the attention of others.

Although it has always been known that the space series uses superconducting batteries, there is no definite information on the specific situation, such as the performance of the superconducting batteries.

Now let’s see…

I’m afraid Kongkan-2 has no energy worries at all!

When a conventional fighter jet performs supersonic cruising, the aircraft's fuel must be consumed rapidly. However, a test of supersonic cruising actually required an hour of supersonic cruising. The energy consumed in the process has exceeded that of a top fighter jet.

Therefore, the superconducting battery used by Kongjian-2 must have amazing power storage data.

"I'm afraid it will reach tens of thousands of kilowatts!" a reporter speculated.

Another reporter said, "It may also reach 100,000 kilowatts. After all, it is a superconducting battery."

"Even for superconducting batteries, one hundred thousand kilowatts is too high, right?"

"There are not one hundred thousand, but there are eighty thousand..."

Amid reporters' surprise at the superconducting battery's charge level, the supersonic cruise stage finally passed.

The next step is the high suspension test.

This stage is relatively simple. Kongjian-2 will decelerate and slowly start to climb up during the deceleration. When it reaches a certain height, because the air becomes very thin, it does not even need to tilt, it just turns on the maximum

The large propeller below sprayed nitrogen downward to provide power, and flew upward in a parallel flight attitude, finally reaching an altitude of 45,000 meters.

Kongjian-2 began to slow down, and finally stopped at a standstill, relying only on power to stay in the air.

Some satellites captured this picture, and they were also very shocked.

If Kongjian-2 were to rise tens of thousands of meters higher, it might even be regarded as a geostationary satellite rather than an aircraft that could rise freely.

Staying still is also one of the tests.

At an altitude of 45,000 meters, the air is very thin, and the auxiliary power nitrogen injection system has become the core power source, but it also has great limitations.

The speed at which an anti-gravity aircraft consumes nitrogen is limited, and the coolant it carries is also limited. The power of the nitrogen injection system is naturally quite limited.

It is possible to stay at high altitude by using the electric thruster and nitrogen injection system directly below, but if it is to cruise at high supersonic speeds, the time it can support is very limited.

"It can only last for about forty minutes before landing to add coolant." Wang Hao said, "At an altitude of tens of thousands of meters, the nitrogen injection system becomes the main power. To fly at supersonic speeds, the consumption of nitrogen must be accelerated.

"

"The faster the speed, the faster it is consumed."

"The reason why we designed it for accelerated use is that the flexibility at high altitude is important to avoid incoming missiles."

The others kept nodding after hearing this.

After that comes the flexibility test, which is to let the anti-gravity aircraft accelerate, turn, and fly up and down at high altitudes.

After all the test projects were completed, the leader quickly issued the order to return.

Returning does not mean the end, but the last test.

Reporters also received news that the aircraft was ready to return. They thought the test was over, but they actually took pictures that were even more amazing than the take-off.

The landing method of Kongjian-2 is not like an ordinary aircraft, which lowers its head from a distance.

It can be said that that kind of landing method has no benefits for anti-gravity aircraft, and may even bring great risks.

Kongjian-2 uses vertical landing.

To put it simply, after slowing down to the point where it is equivalent to hovering, the other thrusters are turned off, only the lowered large thrusters are turned on, and then the aircraft is allowed to fly vertically downward. The other thrusters only serve to adjust the landing position.

When you see a large disc-shaped flying saucer descending rapidly from a high altitude, it will give people a great shock.

It really felt like seeing a UFO...
