Abstract : The first paper demonstrates the importance of stealth penetration ability for future military aircrafts via three areas such as the inspirations from war, the conclusions of a system engineering analysis and the threats from anti-stealth techniques, etc. The emphasis of this paper is placed on the analysis of the new content of tactical-technical requirements for military aircrafts in the early part of the 21st century---the three categories included in the stealth penetration ability are: (1) scattering and radiation characteristics of aircrafts; (2) electronic interference ability of aircrafts; (3) tactical stealth techniques used by aircrafts. The second paper gives a comprehensive introduction and review of various models for predicting fatigue crack growth under spectrum loadings. The basic principles, characteristic parameters, governing equations and strong and weak points of representative load interaction models presented by scholars both here and abroad in over ten years are tabulated for comparison. In addition, the selective principles, computation accuracy and cost-effectiveness of the models are discussed. Keywords: Russian translations. (jhd)
