The next day, Yuan Haochen took Durunik to the IEA Pacific base, the scientific group of the Institute of Aeronautics and Astronautics.

"SHIT, Lily is really an old woman, I swear to God." Durunik scolded all the way. "You should know how busy I am, why I'm in such a hurry to see her, we don't have an appointment, what if she's not available"

"Well, Durunik, I'm absolutely convinced that Lily is an old woman, and her face is full of freckles, so I'm sure I don't mean to fight with you." Yuan Haochen pushed Durukik, and Durunik had to speed up the pace of progress.

"Oh God, you damn Chinese, you know Lily is 10 years older than me, and we're just fellow countrymen."

"I say, Durunik, it seems that you clearly prefer Dr. Minchi's high-voltage radiation to the freckles on Lily's face."

The two of them walked towards the southern periphery of the IEA's (Interstellar Exploration Alliance) Pacific base.

The IEA's Pacific Base is a sprawling underground castle, and it took Hara and Trunik a long time to reach the Institute of Aeronautics and Astronautics.

As with the Institute of Astrophysics, non-members of the Institute must apply for a visit through the Institute's administrative staff in order to enter and leave the Institute.

"Hello, Dr. Lily, there are two guests here who want to visit you." It was a black girl with black pigtails on her head, "Excuse me, sir, what do you call it?" ”

"My name is Durunik, this is Yuan Chen, we are from the Institute of Astrophysics, the lovely Black Pearl Lady." Durunik said after glancing at the black girl.

"Oh, it's Dr. Durunik and Dr. Hara from the Institute of Astrophysics."

"I'm sorry, gentlemen, for keeping you waiting, please come with me." The black girl said politely.

Led by the black girl, Yuan and Chen quickly found Lily in the experimental area.

"Hey, my goddess, it's such a pleasure to meet you." Durunik couldn't wait to come up and shake Lily's hand.

"Nima, Durunik, the great liar! Where is this an old woman with freckles on her face, obviously a half-old who still has charm. Yuan Haochen saw Lily's true face, and couldn't help but curse in his heart.

"Durunik, you won't be scolded by the team leader again, come out and relax." Lily scoffed, it seemed that this guy Trunik often used this excuse to come to her.

"Lily, I'm afraid I'm going to disappoint you this time, I'm here today to introduce a little Chinese brother to you." Durunik tilted his head and said, then stretched out his hand to signal to Hara Chen.

"Dr. Lily, it's a pleasure to meet you, I'm a new member of the Institute of Astrophysics, Yuan Chen."

"Oh, you're so young, Durunik said you're Chinese, I think you're much more handsome than Richard." Lily began to look Yuan up and down.

"Thank you for the compliment, and I hope Richard doesn't hear it."

"Dear Dr. Lily, are you going to keep us standing here?"

"Sorry, let's go to the office and talk, please go this way." Lily began to lead the way in front, making her way through several lab areas to her office. "The research direction of each research institute is really very different." Along the way, the scene in the aerospace experimental area left a deep impression on Yuan Haochen.

There are parts for rockets and spaceships of various sizes. Looking at the various spaceships, Yuan Haochen's heart was suddenly full of strong yearning for space navigation.

"Tell me, what's the matter with me? This young man from China. Lily looked at Yuan Haochen meaningfully.

"That's right, I'm very interested in the aerospace technology at the IEA base, and I specially learned from you." Yuan Haochen was furious by Lily's eyes, but he thought that he had something to ask for, so he still pretended to be calm and said.

"It turns out that this is the case, it is very common for our different scientific research institutes to cooperate with each other to complete their work and exchange scientific research results with each other, please do not be polite."

"But Lily, why do you treat me so badly every time I look for you?" Durunik grumbled from the sidelines.

"yes, I don't remember." Lily looked at Durunik with a mocking look on her face.

"Damn, I thought it must have been a bad decision to be here today!" Durunik couldn't help but start complaining.

"Well, let's talk about aerospace technology first." Yuan Haochen thought to himself that these two people must have a story, but don't continue to talk nonsense.

"You're in a hurry, haha." Dr. Lily said and began to introduce Hara and Durunik

Aerospace technology is a highly comprehensive science and technology, which comprehensively applies the latest achievements in basic science and applied science and the latest achievements in engineering technology, and is closely related to the transformation and development of mechanics, thermodynamics, materials science, electronic technology, automatic control theory and technology, computer technology, and jet propulsion technology.

Since mankind successfully launched satellites by rockets in the 50s of the last century, space technology has developed rapidly after a full century.

After several generations of technological innovations such as simple capsule spacecraft and space shuttles, the most advanced spacecraft built and developed by the IEA have relatively perfectly solved the problems of insufficient power, poor safety and economy.

Today, the space shuttles built by the IEA organization have reusable ultra-large thrust staged combustion cycle hydrogen-oxygen engines, which can be described as surging power.

In addition, all spacecraft are equipped with the latest models of stable nuclear power packs to meet the electrical energy consumption during long-term space voyages.

In terms of rocket thrusters, Lily gave a brief introduction to the ground thrust parameters of hydrogen-oxygen engines in various countries around the world and the IEA:

India 3000KN;

China 3500KN;

ESA 5000KN;

Japan 6000KN;

USA 7000KN;

IEA (Interstellar Exploration Alliance) 10000KN;

"It seems that there is still a big gap between China's aerospace level and the world's most advanced countries or organizations." Seeing this, Yuan Haochen sighed secretly in his heart.
