Trade data for raw materials

Beidou Engine: Helping China's New Chapter in Aerospace In recent years,Trade data for raw materials China's aerospace industry has flourished and become an important force in the global aerospace field. Among them, engine technology is an important part of space exploration. As a high-performance rocket engine independently developed by China, the Big Dipper engine has become a new engine for China's aerospace development. I. Background and significance of the Big Dipper engine In 2007, China successfully launched the first satellite to measure the location, and then China's aerospace industry entered an explosive growth stage. The development of aerospace has put forward higher requirements for engine technology, especially in the independent research and development of new launch vehicles, it is necessary to have a world-class high-performance engine to achieve true independence. PloughBecause of its high reliability, high performance and other characteristics, the engine is known as the "Light of China" and has become an important support for China's aerospace industry. The launch of the Big Dipper engine has filled an important gap in the history of China's aerospace and enhanced the core competitiveness of China's aerospace industry. II. The basic characteristics and distribution of the Big Dipper engine is independently designed and developed by China Aerospace Science and Technology Group Co., Ltd. It is a new engine with high thrust and high combustion efficiency. Based on the research and development of major national aerospace science and technology projects, the Beidou engine was finally successfully ignited and burned in 2017, realizing a full series of tests from design to ignition. The Big Dipper engine includes a variety of models, mainly distributed in the following fields: 1. Medium-sized carrier rocket engine: suitable for medium-sized carrier rockets, with the characteristics of large thrust, low fuel consumption, light weight, environmental friendliness and so on.Two. Large launch vehicle engine: with higher thrust and greater combustion efficiency, it has become the main force among China's large launch vehicles. 3. Nuclear-powered engine: Based on the principle of nuclear fission, it is the development direction of the future aerospace industry, with long-term and continuous high-power output capacity, as well as high reliability and safety. III. Future development prospects The emergence of the Big Dipper engine represents an important milestone in the independent development of high-performance engines in China's aerospace industry. With the continuous development of China's aerospace industry, the Beidou engine will continue to iterate and improve, and gradually realize more refined and complex operation. At the same time, the research and development of the Big Dipper engine will also enter a new stage with the development of future aerospace technology. For example, in the future, aerospace technology will pay more attention to the clean and sustainable development of energy, and the Big Dipper engine will also develop in a more environmentally friendly and efficient direction.In a word, the Beidou engine, as a high-performance rocket engine independently developed by China, has injected new vitality into China's aerospace industry. In the future, China's aerospace industry will usher in a bright future with the help of the Big Dipper engine.
