摘要：

The article considers the problem of reliability of functioning of difficult technical systems on the example of liquid rocket thrusters. Materials for such motors must operate reliably in complicated combination of force and temperature fields under the influence of corrosive media, radiation, deep vacuum and high pressures. However, the requirements for the materials, can be contradictory. The authors suggest the use of risk analysis "tree structure" to solve this problem. Using this method, the authors prove that the reliability of rocket engines can be increased if you use composite materials that combine dissimilar qualities: high specific strength, stiffness, heat resistance, heat-protective properties, etc.
