The tutorial outlines the general principles of rocket and space technology testing. Specific examples show various types of tests and their relationship with each other, with a discussion of the use of appropriate bench equipment in the process of ground bench development (NSO). The problems of methodological support of NSO, its organization and planning are considered in detail. The book discusses various types of tests at all stages of the product life cycle, including autonomous, comprehensive tests, control and flight design tests. Considerable attention is paid to the analysis of typical bench equipment in relation to each type of test. The textbook is intended for students of technical universities studying aerospace specialties, and can also be useful for scientists, graduate students and engineers involved in the creation and NSO of rocket and space technology.
