Nellis, Nellis, Aurora request takeoff, test pilot Robert called over the radio, wearing a spacesuit-like suit and a fully pressurized flight helmet.

At this time, he had already been pulled onto the runway under the traction of the trailer. At the end of the runway, the two engines had been ignited, and all the instruments in front of him were working normally.

And behind him, there is another test pilot, Yorkson. Both of them have many years of flight experience, and they have served in NASA. Although they have never really flown into space, they have completed the astronaut's all items.

Now, their plane will take off directly and then enter the suborbital!

You can take off, I wish you good luck. The voice of the tower came from the headset.

Robert let go of the brakes and fully pushed the accelerator. The two engines each burst out with a thrust of more than 200 kilonewtons, propelling the fighter and gradually accelerating on the runway.

The thrust-to-weight ratio of the fighter is not high, only about 0.6, which can only reach the thrust-to-weight ratio of some World War II-era aircraft. However, this aircraft is not used for fighting!

The aerospace helmet only has a narrow field of vision. Robert looked at the instrument in front of him. The speed had reached more than 200 kilometers per hour. He pulled up the control lever. Finally, the plane raised its head and flew for a few seconds before taking off from the runway. .

Aurora, Aurora, the nanny is waiting in airspace No. 3. The voice of the control tower came from the radio.

nanny! This is a specially modified aerial tanker! In order to reduce the difficulty of taking off, it did not take off with full fuel, but now, after taking off, it flew smoothly to No. 3 airspace. The air tanker with navigation lights on was waiting in the reserved airspace.

This kind of delta-wing aircraft is actually very difficult to operate. Although there is a fly-by-wire system, Robert is still cautious. He pushes the joystick and finally gets close enough to dock.

This aerospace plane uses special liquid methane, and only this special tanker can refuel it.

After refueling, Robert adjusted his course and sent the most anticipated request to the base: Nellis, request for a suborbital flight test.

For the first time, there are still many problems, so just entering suborbital, even if the experiment is over.

Okay, good luck. The echo came from the radio.

Suborbital flight! Robert fully opened the throttle, and the two turbojet engines were constantly absorbing the atmosphere. In the atmosphere, with the help of oxygen, they were constantly accelerating the aircraft, accelerating!

Soon, a shock cone came from the front, already exceeding the speed of sound! Keep accelerating!

When the speed reached Mach 2, Robert flipped the switch. Under the control of the computer, the power of the turbojet engine was rapidly weakened. Detonation engine!

ignition!

Boom! In the combustion chamber, there is an explosive mixture of methane and air. With the pulse ignition, high-temperature and high-pressure gas, the burned gas explodes from the nozzle, and at the same time, a detonation wave is also generated! This detonation wave travels from the nozzle along the combustion chamber. When the burned gases leave the nozzle, the detonation wave bounces off the front of the combustion chamber and rushes out of the nozzle.

Then, this stress wave also left the combustion chamber, leaving only extremely thin air inside, and the next detonation began again!

From the outside, it can be seen that the work of this engine is not continuous. Every time there is a detonation, accompanied by a huge roar, the entire Polar ship accelerates, followed by the second and third times.

Sitting in the cab, this feeling is like the sea water is constantly slapping your back! This unique engine can greatly improve work efficiency!

The pulse detonation engine, even in later generations, is a new type of power, but in fact, the specific research on this kind of power can be traced back to the 1940s. The main mechanism of the pulse detonation engine is to control the periodic explosion wave to generate power.

The research on detonation waves can be regarded as a preliminary investigation, and the German Hoffman is one of the scientists in this field.

In the Cold War, the 1950s and 1960s were the introductory period of pulse detonation engines, and feasibility study tests were carried out. Historically, in the mid-1980s, the US Naval Postgraduate School conducted experiments that largely promoted the development of pulse detonation engines. It is confirmed that a pulse detonation engine with adjustable thrust can be developed.

But now, unlike in history, in the desperate situation and under the threat of war, a lot of money and manpower have been invested. This kind of engine has entered the practical stage!

The detonation wave not only appeared on the engine, but also transmitted to the ground along the air. This night, many residents lost sleep.

what is that sound

For the residents living near Area 51, it's no big deal for some weird things to happen once in a while, but the sound today is so loud that they can't sleep peacefully!

Shake it, shake it, if it doesn't shake, it's a failure! In the air, the two test pilots are also enduring this terrible feeling, and at the same time, the plane is constantly accelerating.

Mach 3, Mach 5, Mach 7!

The height is also constantly climbing! Thirty thousand meters, forty thousand meters!

The air was already quite thin, and the onboard computer system began to close the front air intake. At the same time, the liquid oxygen inside the carrier aircraft finally began to be supplied.

The most important thing for a single-stage orbiting spacecraft is to solve the problem of the thrust-to-weight ratio of the spacecraft!

In the atmosphere, you can use air to participate in combustion, reduce the content of liquid oxygen carried by your side, and don't start using liquid oxygen to support combustion until you leave the dense atmosphere!

At an altitude of 30,000 meters, the edge of the earth can be seen, but now, as the altitude continues to increase, the diffuse reflection of the air is lost, and the surroundings are completely dark!

Through the porthole in front, one can see the boundless darkness of the universe, only the stars in the distance shone dimly, and at the same time, the cockpit also began to become cold.

Keep accelerating!

Mach 10, Mach 15, Mach 20!

As long as the speed exceeds the first cosmic speed, it will become an artificial satellite! And now, the speed of this aerospace plane is about to reach!

The height has also risen to 80,000 meters!

The experiment was a complete success!

If we continue to climb up, we will encounter a space laser cannon of the Soviets at an orbit of 120,000 meters. According to the results given by the computer, the hit rate will exceed 50 percent. At this moment, shouted Yorkson in the back cabin.

Space laser cannons, the sword of Spartacus hanging over the heads of Americans! The Aurora they are experimenting with now is used to deal with the laser cannons of the Soviets!

Now, the time is right!

There is still fuel left, we should be able to get there. Robert said loudly. At this time, the ground can no longer communicate with them except to monitor them. The communication satellites of the United States are no longer able to form a normal network. It can be said that they now have strong autonomy!
