Changkong Fighter

Chapter 215 Variable Cycle Engine
Huala-huala-Eagle sat in an office of Chengfei, constantly flipping through the technical manual in his hand. When he saw some places that needed attention, he would stop and look at them for a while, and when he saw the unclear parts, he would write them down and go back to ask the experts.

Eagle is very capable enough to be a test pilot, but aircraft are developing too fast. He also needs to study carefully some of the new technologies on the sixth-generation aircraft and understand the principles.

Test pilots are also an important part of aircraft research and development. Many problems that cannot be discovered on the ground have to be discovered in the sky. This way, they can solve the problems when dangerous situations occur in the air.

As he was reading, Lao Ying suddenly snapped the technical manual shut and turned to look at his mobile phone. On it was Song Xizhu's profile picture with the note: Daughter.

[Daughter: I joined the Shen Sixth Generation]

"Hahaha, Old Song, this Xiao Zhu wants to go against you. We are flying the sixth generation aircraft here, and she is going to participate in the integration of Shen's sixth generation radar system." The thin man joked on the side.

This daughter refused to join the same project team with her father, but chose a project that was in "healthy competition" with her father.

"She's not mad at me, but she is mad at me."

Song Jiuzhou, who had always been calm, sighed in his heart. As a test pilot at the Flight Test Institute, he had almost no time to take care of his family. It was all up to his wife to raise the children. He felt guilty towards his family and daughter.

"Are there any other reasons?" the thin man asked curiously.

"It's all right now."

Lao Ying was about to say something when he shut his mouth and thought about that kid Liu Jun.

To be fair, he was an excellent pilot, impeccable in every way, but even though he tried his best to control himself, he still made me feel irritated.

Seeing that Eagle didn't say anything, the thin man didn't ask either. He flipped through the internal newspaper. The headline on the front page was the commendation for Changkong, and he clicked his tongue.

"Tsk tsk, Changkong is really amazing. He has shot down 80 planes, most of which are WVRs. No wonder Shen Fei puts his trust in him."

As the front line of the battle, carrier-based aircraft have come up with the following plan to fight against aliens: drones assist manned aircraft; they focus on medium-range and short-range combat, and manned aircraft are responsible for command on dangerous drones.

Chengfei, combined with ginkgo leaves, transformed into an aerial arsenal ship, carrying a large number of advanced long-range air-to-air missiles to suppress targets from a distance and completely eliminate all enemies before entering the WVR.

It sounds like both sides have gone to their respective extremes, but there is no conflict here at Southeast University. Both Shenfei and Chengdu Aircraft Corporation are part of the Southeast University system and are responsible for their respective different fields.

"The main purpose is to counter the alien civilization's kill chain. WVR should be left to drones. Changkong always wants to dogfight."

Listening to the thin man's praise, Eagle muttered something, then put his phone into flight mode, adjusted his status, and continued to study the technical manual.

Even at such an old age, I must learn new knowledge, otherwise I really can't keep up with the development of aviation and aerospace.

The Aero Engine Research Institute is a technical research unit directly under the Dongda Aero Engine Group. It mainly conducts strategic, cutting-edge and basic research on aero engines and is a national scientific research institution.

In a laboratory, an alarm sounded, reminding all researchers that the experiment was about to begin.

"Confirm each position one last time, operating system?"

"Ready!"

"Computer records?"

"Ready!"

"Three, two, one, start!"

With a click, the toggle switch flipped, and the experiment began. The tester pushed the throttle on the test bench and looked at the engine data. "Up, running well!"

The tail of the engine on the test bench spewed out flames with Mach rings, and the thrust continued to increase.

"Wind tunnel ready for ram mode testing. Three, two, one, go!"

With a loud bang, the hypersonic wind tunnel blew out a high-speed airflow and sprayed it onto the test engine. The shock wave compressed the air into the combustion chamber. The flame ejected from the tail of the engine was larger and longer than before, and the thrust of the engine was greatly increased.

However, the operation time of the hypersonic wind tunnel is not long, only a few seconds. Soon after the airflow calms down, the engine leaves the ramjet mode, the duct changes, and enters the turbojet working mode.

Almost at the same time, an oblique detonation engine was also being tested on a test bench in the laboratory next door.

The shock wave generator continuously ignites the mixed fuel and air, forming a high-temperature and high-pressure explosion wave. This creation of the god of industry continuously spews out balls of violent combustion gas at the tail. The test bench moves up and down and left and right to test whether the engine is working stably.

Soon, the engine's operating mode was switched from oblique detonation to a conventional turbofan, and then through internal mechanical changes, the bypass was changed to a turbojet mode more suitable for high-altitude operation.
Several veteran academicians stared at the parameters of the two engines and discussed something in a low voice.

The sixth-generation aircraft currently being researched by the University of Tokyo is not a true sixth-generation fighter, but an improved model based on the J20 and J35. It will only become a true sixth-generation aircraft when the variable cycle engine is installed on it.

Qinyuanchun Changsha

[Standing alone in the cold autumn, the Xiang River flows north, at the head of Orange Island.]

[Look at the mountains covered in red, the forests dyed in all colors; the river is clear and turquoise, hundreds of boats compete for the current.]

Liu Jun looked at the poems engraved on the poetry stele, and he relaxed for a rare moment, the kind of complete relaxation from the inside out.

I spent two days with my parents at home, and gave a half-day lesson to the pilots from my hometown. Although it was called a class, I just talked about my combat ideas and key points when facing alien civilizations. After that, I drove a borrowed J11B to Orange Island.

There are very few tourists in the entire tourist attraction. Although the University of Tokyo has not entered a wartime state, various factories have begun to increase their production capacity, and the military industry system has been fully expanded.

It’s also good to have fewer people, as you don’t have to squeeze in with others.

After carefully reading the above poems, Liu Jun put on sunglasses and a mask to prevent being recognized, and strolled around the island. He first came to Wentian Terrace to wait for the sunrise.

The sun rises in the east, and the sunlight shines on the statue at the helm, looking young and vigorous.

At this time, he really wanted to know what kind of mood the old man was in when he "asked the vast" earth here.

Suddenly, Liu Jun felt someone was looking at him. He turned around and saw two people who looked like tourists taking pictures with cameras.

Liu Jun nodded at them and stopped paying attention to them. He had seen these two people before and they should be here to protect him.

When the two realized that Liu Jun's attention was not on them, they looked at each other.

"Master, it's hard to hide with so few tourists here." The young man complained.

"Okay, protect the good people. Fortunately, it's the last day."

It's unclear whether the Adventists actually took action against Changkong, but some internal security personnel were there to protect him when he went out. Fortunately, Liu Jun was flying around the country in a J11B, and the Adventists couldn't keep up with his speed even if they tried.
