作者 刘振烈 《低温与特气》 CAS 1989年第3期29-31,共3页
氢和氧反应能放出大量的热,燃烧生成物的分子量很小,该反应提供的比推力比任何化学推进剂都大,且不破坏生态循环,不污染环境。因此,液氢是理想的洁净燃料。目前,中、苏、日、法(欧洲13国)、美等国家,都先后在宇宙开发中使用了液氢-液氧... 氢和氧反应能放出大量的热,燃烧生成物的分子量很小,该反应提供的比推力比任何化学推进剂都大,且不破坏生态循环,不污染环境。因此,液氢是理想的洁净燃料。目前,中、苏、日、法(欧洲13国)、美等国家,都先后在宇宙开发中使用了液氢-液氧发动机(氢-氧发动机,即第二代发动机)。 展开更多

This paper provides a detailed introduction to and analysis of the course of China's technological innovation in liquid hydrogen/liquid oxygen(LH2/LOX)rocket engines from a historical point of view.It starts with the investigation of LH2/LOX rocket engines by relevant departments of the Chinese Academy of Sciences in the 1960s and their preliminary achievements.Then,the policy decision concerning LH2/LOX engine development,the project approval of the Long March-3(Chang Zheng-3,CZ-3)rocket,and the process of developing LH2/LOX engines are analyzed in detail,followed by an introduction to and summary of the development situation and technical innovation characteristics of China's LH2/LOX engines as they grew from 4 tons to 8 tons,and finally to 50 tons.Finally,the paper briefly analyzes the innovation experience connected with China's LH2/LOX engines. 展开更多
