"Nellis, Nellis, Aurora is requesting takeoff." Test pilot Robert shouted over the radio, wearing a suit similar to a spacesuit and wearing a fully pressurized flight helmet.

At this point, he was already on the runway under the traction of the trailer. At the end of the runway, the two engines had been fired, and all the instruments in front of him were working normally.

Behind him sits another test pilot, Yorkson, both of whom have many years of flight experience and served in NASA. All items.

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

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

Robert released the brakes and pushed the accelerator all the way. The two engines each burst out with a thrust of more than 200 kN, pushing the fighter plane and gradually accelerating on the runway.

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

The space helmet only has a narrow field of view. 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 lifted its head and flew for a few more seconds before it took off from the runway. .

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

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

This kind of delta-wing aircraft is actually very difficult to operate. Although there is a telex system, Robert is still cautious. He pushes the operating lever 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 aligned the course and sent the most anticipated request to the base: "Nellis, request a suborbital flight test."

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

"Okay, good luck to you." There was an echo on the radio.

Suborbital flight! Robert fully opened the throttle, and the two turbojet engines continuously absorbed the atmosphere. In the atmosphere, with the help of oxygen, the aircraft was continuously accelerated, accelerated!

Soon, a shock cone came from the front, which had already exceeded 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 rapidly weakened. At the same time, the sharp cone in front of the engine inlet shielded the turbojet engine, and it had become a pulse Knock the engine!

ignition!

"Boom!" In the combustion chamber, an explosive mixture of methane and air is filled. With the pulse ignited, high temperature and high pressure gas, the gas blasted out from the nozzle after combustion, and at the same time, the detonation wave was also generated! This detonation wave travels from the nozzle forward along the combustion chamber. When the combusted gases leave the nozzle, the detonation wave bounces off the front end of the combustion chamber and rushes out of the nozzle.

Then, this stress wave also left the combustion chamber, leaving only extremely thin air in it, and the next knocking started again!

From the outside, it can be seen that the work of this kind of engine is not continuous. Every time the detonation is accompanied by a huge roar, the entire Polaris accelerates, and then it is the second and third time.

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

The pulse detonation engine, even in later generations, is also a new type of power, but in fact, the specific research on this 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 the detonation wave can be considered as a preliminary investigation, and the German Hoffmann is one of the scientists in this field.

In the Cold War, the 1950s and 1960s were the entry-level period for pulse detonation engines, and feasibility studies were conducted. Historically, in the mid-1980s, the U.S. Naval Graduate School conducted experiments to a large extent to promote 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 a desperate situation, under the threat of war, a lot of money and manpower have been invested, and this engine has entered a practical stage!

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

What is that sound?

For the residents living near Area 51, it's nothing to do something weird occasionally, but today's sound is so loud that they can't sleep peacefully!

Shake it, shake it, if it doesn't shake, it will fail! In the air, the two test pilots were also enduring this terrible feeling, and at the same time, the plane was constantly accelerating.

Mach 3, Mach 5, Mach 7!

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

The air ~www.wuxiaspot.com~ is already quite thin, and the onboard computer system begins to close the front air intake. At the same time, the liquid oxygen inside the carrier finally begins to be supplied.

The most important thing for a spacecraft entering orbit in a single stage 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 yourself, and only start using liquid oxygen to support combustion until you leave the dense atmosphere!

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

Through the front porthole, you can see the infinite darkness of the universe, only the stars in the distance, twinkling dimly, 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 Soviet space laser cannon at an orbit of 120,000 meters. The result given by the computer will have a hit rate of more than 50%." At this moment, shouted Yorkson in the rear cabin.

The space laser cannon, the Spartak sword hanging above the Americans! The Aurora they are experimenting with now is used to deal with the laser cannons of the Soviets!

Now, the opportunity is right!

"There's still fuel left, and we should be able to get there," Robert exclaimed. At this time, in addition to monitoring them, the ground has been unable to communicate with them. The communication satellites of the United States are now unable to network normally. It can be said that they now have strong autonomy!
