Chiwu System

When the rocket flies forward, the fuel and oxidant burn rapidly in the combustion chamber, and the high-temperature and high-pressure gas produced is ejected backward at a speed of several kilometers per second. We regard the rocket and the ejected gas as two interacting objects. The point of action is on the rocket. When the rocket ejects, it is equivalent to giving the gas a backward thrust. According to Newton's law, the ejected gas will give the rocket a reaction force through the point of action on the rocket, causing the rocket to fly forward. This physical process has nothing to do with air, so even in space without air, the rocket will still fly at high speed.

This year, the gravel drifting from Gaia lacks the smell of sulfur. I heard that during the civilized Chinese New Year, firecrackers are prohibited. I jumped up from the spaceship and went to grab a red envelope, but the robot behind me pulled me back, "No red envelope for unsigned works." Suddenly, a laser beam shot at me. I closed my eyes and prepared to choose a target for reincarnation. Countless recommendation votes helped me block the laser. Thank you for saving me. At this time, a gentleman asked me: Can you guarantee the update volume? I said, yes! But mine is a handmade product and cannot be mass-produced. Another fairy sister asked me, would you be embarrassed if I recommended you to a friend? I say, handmade products, make them for the first time and adjust them according to your friends' tastes, they will always be satisfied.

I heard that Gaia has a food called glutinous rice balls? Craftsmanship practices are very inspiring for developing space weapons

I have been voting silently for several days, so cheers and support you unswervingly.

Welcome to make a brick 🙏 1. The high-temperature and high-pressure gas recoils to gain velocity. The theoretical basis is ft=mv. The problem is that in outer space without air friction, we cannot get a lasting f, so the equation here can only be mv=mv. Whether the pressure of the recoiled air is high or not is of some significance, but it is not significant. The quality of the recoiled gas is the key. For civilian spacecraft, if the speed is not too fast and the mass is not too large, it is meaningful to accelerate the gas recoil during operation; for military heavy ships, how much speed can the recoil increase? 1% Is of little significance for combat. Welcome to communicate in the future, the second volume is full of these contents. 2. Regarding the steering of ships using planetary gravity, the sixth paragraph of Chapter 1 mentions half a sentence. 3. Missiles can be used in outer space, which I will mention in Chapters 42 and 45.

Before you even read the text after clicking in, the common sense that rocket sea level specific impulse is generally lower than ** specific impulse was flatly denied by the author 🙏

If the author made a mistake, just correct it, don't be harsh! You said rockets can't accelerate in space! Then tell me how the United States came back from the moon landing! Bounce back by the moon!

The article is delicately conceived yet unrestrained, the writing style is real and equally gorgeous; the plots are interlocking and fascinating, and have the potential to be completed in one go; the emotional explanation is clear and implicit, and accurate; like it

Such a good book, I definitely have to recommend it. If I can't recommend it, it's really unreasonable.

I have never revised the book that I have been a big fan of since the beginning! Come on, author, hey, hey, hey, hey!

Although the author is writing a novel, the things he expresses are very real, and many of them touch his heart~~

I discovered this article yesterday and couldn't put it down. I read it until around two o'clock in the middle of the night and finally finished it!

Good article, wonderful ideas, unique ideas, good writing style, please support me

This book gave me a completely different feeling than any other book on the same subject. It's really great! Give it another silent thumbs up~

I have recommended it every day since I was qualified to recommend it. I am willing to use my meager strength to increase the motivation to continue writing! Come on, support you! !

I have read a lot of books recently, and this one is my favorite. I highly recommend it! Push up hard.

I have been reading too much about ****, and suddenly I saw a really good book. I was shocked. After reading it, I felt that my brain was much easier to use, hahaha.

Very good writing skills, clear ideas, good-looking

Keep writing, I really want you to write tens of thousands of words a day, and I will give you the recommendation votes for 4 chapters every day, so work hard! 🤝🤝🤝🤝

As the story develops, the plot unfolds bit by bit, and the previous foreshadowing gradually emerges. The novel is very interesting and is expected to be a masterpiece.

A great product for amateur leisure, I highly recommend it.

Do you need to collect minor character names? Please make soy sauce. 😁😁

Take your time! Don't rush! The text control is very good, and the recommendation vote is given 😄😄

The large description of the environment can really enhance the atmosphere and set off the progress of the plot, which is good!

The large style of writing is concise and clean, which looks comfortable and smooth, and is in the process of being updated...

Brother has opened a new book, please come on and support me.

I found that the title of each chapter of the author has a meaningful meaning. It's so lofty.

I came to collect it. It was recommended by a friend. It looks good. I will also recommend it to my friends.

The male protagonist is still a bit kind, and now the more evil he is, the more interesting he is, but this is okay, it's pretty good. The most important thing is to maintain this writing style.

The heroine is so kind——, I feel sad 😭😭
