The content of the aerospace science and technology knowledge handwritten report is mainly related to aerospace, specifically:
1. The aerospace science and technology handwritten report information: China Aerospace. The abbreviation of CASC is a company of the Fifth Research Institute of the Ministry of National Defense of the People's Republic of China. For details, please see "China Aerospace Science and Technology Corporation".
2. The purpose of China’s development of aerospace industry is: to explore outer space and expand understanding of the earth and the universe; to peacefully use outer space to promote human civilization and social progress and benefit all mankind; to meet the needs of economic construction, science and technology development, national security and social progress, improve the scientific quality of the entire population, safeguard national rights and interests, and enhance comprehensive national strength.
3. Knowledge of aerospace science and technology. The characteristics of electronic equipment on aerospace vehicles are: small size, light weight and low power consumption; ability to work in harsh environmental conditions; high efficiency, high reliability and long life. On high-performance aircraft and spacecraft, these requirements are particularly stringent. The cabin volume, load capacity and power supply of aircraft and spacecraft are strictly limited. For every 1 kilogram increase in the weight of the equipment on the satellite, the launch weight of the launch vehicle will increase by several hundred kilograms or more.
4. The main development direction of aerospace electronics technology is to make full use of electronic computers and large-scale integrated circuits to improve the integration, automation and intelligence level of aerospace electronic systems; to improve real-time signal processing and data processing capabilities and data transmission rates; develop high-speed and ultra-high-speed large-scale integrated circuits; develop electronic technology in higher frequency bands (millimeter waves, infrared, optical frequencies); develop various devices with higher reliability and longer lifespan kind of electronic components.
