rocket reads

Rocket could be a character in a children's book that has the ability to read stories.

It can gain knowledge from the story.

Rockets were used to carry spacecraft called space launch vehicles. Spaceships were space vehicles that could ensure astronauts to perform aerospace missions in outer space and return to the ground. They were single-use return spacecraft. Space launch vehicles could be used as a means of transportation for spacecraft into space. For example, the Long March series of launch vehicles could send Shenzhou series of manned spacecraft and Tianzhou series of cargo spacecraft into space; the Lijian II liquid launch vehicle would undertake the launch mission of the light boat cargo spacecraft.

Model rockets were made of a single soft material (such as textile, tissue paper, or plastic film) with a length to width ratio of at least 10:1. They were mostly used for indoor experiments and competitions. The largest supplier of rocket model kits was Estes. If he wanted to start from scratch, he needed to first determine the diameter of the rocket engine so that he could fit the "engine cylinder" on the rocket to prevent the engine from pushing up through the rocket. The engine had to be tightly fitted to prevent it from falling off when it rose. It was better to use a second-hand engine in the process. You could also refer to books such as Van Milligan's "Model Rocket Design and Construction" and "69 Simple Science Exposition Items with Model Rockets." You could also check the website of the National Rocket Teachers Association and NASA's website to obtain relevant knowledge. In order to improve the flight performance of the rocket model, the correct design and production of the streamer could be done to increase the resistance of the streamer when it descended and to reduce the weight of the arrow and the streamer. The streamer material can be selected to be light and have a certain hardness, such as gift wrapping paper. The size of the streamer is usually 90 - 110(mm) in width and 900 - 1200 (mm) in length. After the streamer is folded, each fold is ironed with an iron to increase the resistance of the streamer when it descends. In addition, there was a three-stage rocket model in commercial operations, including the concept of first-stage fuel user base, second-stage fuel conversion rate, and third-stage fuel fission layer.

The following is a method to make a rocket by hand: 1. ** Material preparation ** - Choose an empty 1.5-liter soda bottle as the main body of the rocket. Make sure the bottle is clean and free of residue. - Prepare an air pump to inflate the rocket. - The cardboard was used to make the tail of the rocket. - The tape was used to fix the various parts. - Matches or lighters (used to ignite solid fuel). - Safety glasses to protect the eyes to ensure safety. 2. ** Production Steps ** - ** Prepare the rocket body **: The empty plastic bottle is the rocket body. - ** Making Tail Wing **: You can use three pieces of cardboard of the same width, one of which is slightly longer. He removed the middle part of the first piece of cardboard and turned it into a frame. He cut a strip from both sides of the second piece of cardboard and stuck the cut strip to both sides of the third piece of cardboard. Then, he stuck the first frame. Finally, he inserted the remaining second piece of cardboard and used two rubber bands to bounce them to both sides. Then, he decorated the rocket launcher. The rocket launcher was ready. He could also draw a few rockets and put them in the middle. He could pull them and launch them. 3. ** Propulsion system related (if involved)** - The propulsion system of a rocket usually consisted of fuel and an oxidiser. Self-made rockets could use solid fuel, such as gunpowder or a mixture of sugar and potash. It was important to note that self-made rockets were dangerous. Safety must be ensured during the operation and relevant safety regulations must be followed. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
