Fallen Star: Second Earth

"This meeting mainly discusses the practicality and feasibility of electromagnetic drive thrusters. Now let's ask Xiao Li, the developer of this thruster, to give you a detailed introduction." Chen Zhenggang looked at Li Qingfeng. Li Qingfeng quickly walked to the front row and took the microphone from the dean with respect.

"This time I mainly show you the feasibility and practicality through comparison." Li Qingfeng paused, "For the two most important thrusters at the moment, the first thruster is a nuclear-powered thruster, but this kind of propulsion Not only does the fuel load requirement of the spacecraft be too high, but the kinetic energy provided is not enough to sustain the spacecraft to fly across the galaxy. This results in this type of spacecraft being able to only fly within the solar system. That is, the effective flight radius of this type of spacecraft is 1.9 light Years. So this kind of thruster is not feasible for us. As for the electromagnetic drive thruster I use, the first major advantage is that it does not require fuel. The surface of the star ring we designed is all high-efficiency. Solar panels can effectively absorb energy from stars. This completely solves the problem of energy shortage. The second biggest advantage is that it can reach sub-light speed. Although this speed cannot match the speed of dark matter thrusters, the fastest can still reach 0.3 times the speed of light, which is enough for us to explore nearby galaxies. The second type of thruster is the dark matter thruster mentioned above. Although this thruster can quickly increase the speed to 0.7 to 0.8 times the speed of light, this type of thruster is not stable. He needs to build enough protection devices and backup thrusters to prepare for emergencies. Our electromagnetic thrusters use a new innovative design, which is the star ring."

Li Qingfeng pointed to the model spaceship in the 3D image. Its shape was very different from the ordinary spacecraft in service. First of all, it was surrounded by two very large rings, which were the star rings that Li Qingfeng said. The overall spaceship model looks like an airship used in ancient times.

"The concept of other spacecraft design did not consider that the spacecraft can reach the speed of light. When the spacecraft reaches the speed of light, the kinetic energy it possesses is very large, so you need to generate the same kinetic energy to offset it. So we adopted this approach. The technology of external thrusters allows acceleration or deceleration by placing electric thrusters on the star rings, and the thrusters used are the same thrusters, which effectively increases the payload of the spacecraft. These two rings One is the active ring and the other is the driven ring. It can effectively ensure the operation of the propulsion system. The above is my introduction to the electromagnetic drive thruster. If you have any questions, you can ask them."

At this time, a hand was raised, and the slightly thin researcher said: "The biggest problem that can be seen from your model is how does this spacecraft enter space from the ground?"

Li Qingfeng pushed his square eyes and said in a measured tone: "Since you can't enter space from the ground, why are you still struggling with how to take off from the ground? Our team's design concept did not intend for it to be built on the ground from the beginning! In the courtyard Last month, we reached an agreement with Planet Explorer Alliance. They will help us build a space station near the moon and Mars that can accommodate spacecraft construction and Mars exploration, so that we can not be afraid of some people with ulterior motives stealing and destroying our hard work. . And this space station can act as a thruster to help the spacecraft complete the first stage of acceleration and save electric energy."

The audience burst into thunderous applause.

At the end of the meeting, Chen Zhenggang said to his teacher: "You have a good student. I believe the application of this technology will revolutionize the entire aviation field. Shang Shouhua, tell me how lucky you are to have picked up such an excellent student." student?"

Shang Shouhua symbolically touched Zi's imaginary beard and said with a smile: "Luck is part of strength. If you have the ability, you can find a student who is as studious and inquiring as my precious apprentice. Can't do it? Besides, I This apprentice was taught by me, and his strength is a symbol of my strength." Shang Shouhua began his own bragging journey.

Chen Zhenggang instantly slapped him in the face and said: "With regard to your virtue of drinking every day, if Qingfeng hadn't been willing to work hard, you would have delayed important events in your life. As we all know, you are unreliable. It’s well-known in the hospital.”

Shang Shouhua looked embarrassed and couldn't get off the stage, so he winked at Li Qingfeng. Li Qingfeng looked at the sky and said, "Wow, the moon is so round today."

Shang Shouhua said: "Yesterday's weather forecast said it was cloudy. Now there is no moon outside, and there is only an artificial sun in the sky. Can you find a better reason for lying, my precious apprentice." After saying this, Shang Shouhua Squeezing Li Qingfeng's shoulders, Li Qingfeng felt his scalp numb. He quickly said: "I remembered, there was some data that I haven't sorted out just now. I have to go back and sort it out quickly. Teacher, please talk to the dean slowly. I'll go back first."

Both the dean and Shang Shouhua smiled as they watched Li Qingfeng escape.
