Use of Computer Programs in Aircraft Design 650054

The increasing complexity of aircraft structures is creating new problems in structural analysis. The problems are in the areas of static and dynamic loads analysis, stress analysis, statistical methods, fatigue, flutter, acoustics, and associated fields, including aerodynamics and heat transfer. These developments are increasing the need for fully automatic computer programs for design use. Such programs must be technically sound, efficient in the use of computer time, rapid in providing answers for design, and simple enough to minimize training requirements. This paper reviews existing methods from the standpoints of technical requirements, personnel familiarization, and effectiveness. Recommendations are made for future developments.
