中苏关系正常化之后,两国在航天领域内的交往日益增多。前不久,应苏联通用机械工业部的邀请,我们有机会到苏联访问。访问过程中,我们参观了苏联液体火箭发动机等方面的几个重要设计机构,其中包括能源机械联合体(原格鲁什柯设计局)、科学生产联合体(原扬格尔设计局)、能源科学工业联合体(原科罗廖夫设计局)、热过程研究所及材料与工艺研究所等。 After the normalization of the Sino-Soviet relations, the exchanges between the two countries in the aerospace field have been increasing. Not long ago, at the invitation of the General Machinery Industry Department of the Soviet Union, we had the opportunity to visit the Soviet Union. During the visit, we visited several important design agencies in the Soviet Union such as liquid rocket engines, including the Energy Machinery Consortium (formerly Gelushike Design Bureau), the Scientific Production Consortium (formerly the Design Bureau of Janger), the Energy Scientific Industry Consortium (formerly Korolev Design Bureau), Thermal Process Institute and Institute of Materials and Technology.
