"Launch Vehicle" PPT courseware

launch vehicle

Whether it is the launch of satellites, or the launch of space shuttles or spacecrafts, they must use rockets to leave the earth. So in this lesson we will learn about rockets and their reasons for liftoff.

The hometown of Rockets is China

According to ancient records, the word "rocket" first appeared in the Three Kingdoms era in the 3rd century AD, which has a history of more than 1,700 years. At that time, in the battle between the enemy and ourselves, people called an arrow with a flammable substance on the head, which was ignited and shot at the enemy, and which carried fire when flying.

In the Ming Dynasty, Wan Hu, a scholar-bureaucrat, tied 47 homemade rockets to a chair, sat on the chair, and held a big kite with both hands. Imagine using the thrust of a rocket to fly into the sky, and then landing smoothly with a kite. But unfortunately, the rocket exploded, and Wanhu also sacrificed his life.

Commemorating the great pioneers

Currently, only rockets can send people into space. Based on this standard, the earliest manned space flight should be the Wanhu Flying Sky about 600 years ago. According to research by Western scholars, Wan Hu was “the first person in the world who wanted to use rockets to fly.

NASA once named a crater on the moon's surface "Wanhu" to commemorate it.

The importance of rockets

When we evaluate a country's aerospace capabilities, we mainly look at whether the country's rockets have the ability to carry large-scale aerospace equipment. Rockets are the foundation of the aerospace industry. Without the backing of powerful rocket technology, satellites and manned spacecraft cannot develop steadily.

The development of my country’s rocket industry

China began to develop modern rockets in 1956. On April 24, 1970, the "Long March 1" carrier rocket was born, and the first satellite "Dongfanghong 1" was successfully launched. China's aerospace technology has taken an important step.

Long March series rockets

After more than fifty years of development, our country has developed five series of rockets, Long March 1, 2, 3, 4, and 5, with more than a dozen different specifications. They come in different sizes, have different carrying capacities, and have different ranges of use.

Long March 1

Long March 1 is a three-stage launch vehicle developed to launch my country's first artificial earth satellite, Dongfanghong 1. It has 4 types A, B, C and D. The Long March 1 D-type rocket (also called D-type) is still in use. It is mainly used to launch lighter satellites, with a maximum load capacity of 850 kilograms.

Long March 2

The Long March 2 bundled launch vehicle, referred to as Changer Bundle, is a large two-stage bundled launch vehicle with four boosters with a diameter of 2.25 meters and a height of 15 meters bundled on the outside of the first stage. It is mainly used to launch spacecraft or satellites in low-Earth orbit.

Long March 2 F rocket

It is the sixth model of the Long March 2 series of rockets and is currently the only rocket used in China to launch manned spacecraft. It is based on the Long March 2E type rocket, the "Chang 2 Bundle" rocket, and was developed in accordance with the requirements of the manned space engineering.

The principle of rocket launch

Observe experiments on flying balloons, as well as scientific and educational short films. Understand the basic principles of backlash.

The rocket's injector expels the combustion gases backward, creating a reaction force that launches it into the air.
