Chapter 1153 Combined Pulse Detonation Engine

"Nellis, Nellis, Aurora requests takeoff." Wearing a suit similar to a space suit and a fully pressurized flight helmet, test pilot Robert shouted on the radio.

At this time, he was towed onto the runway by a trailer. At the end of the runway, the two engines had been ignited, and in front of him, all the instruments were working normally.

Behind him sat another test pilot, Jackson. Both of them had many years of flying experience and had served in NASA. Although neither of them had actually flown into space, they had completed all astronaut projects.

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

"You can take off. Good luck to you." The voice of the tower came from the headset.

Robert released the brake and pushed the accelerator to full throttle. The two engines each burst out with a thrust of more than 200 kilonewtons, pushing the fighter plane to gradually accelerate on the runway.

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

The space helmet had only 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 the joystick, and finally, the plane raised its head and flew for a few more seconds before taking off from the runway.

"Aurora, Aurora, the nanny is waiting in airspace number three." The voice of the tower came from the radio.

Nanny! This is a specially modified aerial refueling aircraft! In order to reduce the difficulty of takeoff, it did not take off with full fuel. Now, after taking off, it flew smoothly to the No. 3 airspace. The aerial refueling aircraft with navigation lights on was waiting in the designated airspace.

This kind of advanced aircraft is actually very difficult to operate. Although there is a fly-by-wire system, Robert was still very cautious. He pushed the joystick and finally got close enough to dock.

This type of space plane uses special liquid methane, and only this special refueling machine can refuel it.

After refueling, Robert aimed at the course and sent a most anticipated request to the base: "Nellis, request a suborbital flight test."

It’s the first time and there are still many problems, so just entering the suborbital orbit is considered the end of the test.

"Okay, good luck to you." An echo came from the radio.

Suborbital flight! Robert opened the throttle to the fullest, and the two turbojet engines continued to absorb the atmosphere. In the atmosphere, with the help of oxygen, the aircraft continued to accelerate, accelerate!

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

When the speed reached Mach 2, Robert flipped the switch, and under the control of the computer, the power of the turbojet engine rapidly weakened. At the same time, the pointed cone in front of the engine inlet shielded the turbojet engine, turning it into a pulse detonation engine!

ignition!

"Bang!" The combustion chamber is filled with explosive methane and air mixture. As the pulse ignites, high-temperature and high-pressure gas, the burned gas explodes from the nozzle, and at the same time, a detonation wave is generated! This detonation wave propagates forward along the combustion chamber from the nozzle. When the burned gas leaves the nozzle, the detonation wave rebounds from 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 inside, and the next explosion began again!

From the outside, you can see that the operation of this engine is not continuous. Every detonation is accompanied by a huge roar, and the entire Polaris accelerates, followed by the second and third times.

Sitting in the cab, it feels like the sea water is constantly hitting your back! This unique engine can greatly improve work efficiency!

The pulse detonation engine is a new type of power even in later generations, 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 detonation waves can be regarded as preliminary research, and the German Hoffmann is one of the scientists in this field.

During the Cold War, the 1950s and 1960s were the introductory period for pulse detonation engines, and feasibility research tests were conducted. Historically, in the mid-1980s, experiments conducted by the U.S. Naval Postgraduate School greatly promoted the development of pulse detonation engines and confirmed that a pulse detonation engine with adjustable thrust could be developed.

But now, unlike in history, with no other options and under the threat of war, a huge amount of money and manpower has been invested, and this engine has entered the practical stage!

The detonation wave not only appeared in the engine, but also spread through the air to the ground. Many residents suffered from insomnia that night.

What's that sound?

For residents living near Area 51, occasionally some strange things are nothing, but the noise today was so loud that they couldn't sleep peacefully!

Shake, shake, if it doesn’t shake, then it’s a failure! 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 altitude is also constantly rising! 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 aircraft finally began to be supplied.

For a single-stage orbital spacecraft, the most important thing to solve is the problem of the spacecraft's thrust-to-weight ratio!

Within the atmosphere, air can be used to participate in combustion, reducing the amount of liquid oxygen carried by one's side. Only after leaving the dense atmosphere can liquid oxygen be used to support combustion!

At an altitude of 30,000 meters, you can see the edge of the earth. But 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, one can see the boundless darkness of the universe. Only the stars in the distance are flickering with dim light. At the same time, the cabin is beginning to become cold.

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

The altitude also rose to 80,000 meters!

The experiment was a complete success!

"If we continue to climb, we will encounter a Soviet space laser cannon in an orbit of 120,000 meters. The computer will give us a hit rate of more than 50 percent." At this moment, Yorkson shouted in the rear cabin.

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

"There is still fuel left, we should be able to get there." Robert said loudly. At this time, the ground could no longer communicate with them except for monitoring them. The US communication satellites could no longer form a normal network. It can be said that they now have strong autonomous capabilities!
