    words, the complex technical tasks of airframe development must be accomplished with signif-icantly reduced man-power and within shorter time frames. Traditional design methods, that iterate manually between loads calculations and sizing of structural members may no longer con-verge quickly enough for shortened development.

SYNTHESIS OF AIRCRAFT STRUCTURES USING INTEGRATED DESIGN AND ANALYSIS METHODS - STATUS REPORT As an example of the complexity of the mathematical model available in the data base, a finite element model of one supersonic transport configuration is shown for structural synthesis procedures, Therefore, resizing is carried out by.

The airframe weight is only twenty to thirty percent the gross weight of the aircraft; therefore, one can expect the monetary impact of structural weight savings to be even higher. Any weight savings during the very early design phases can be looped back through.

The unit has been designed to provide learners with a general understanding of airframe structural concepts, construction and protection methods. In particular, the loads imposed on airframe structures, the basic structural members used to take these loads and the structural design concepts used to ensure continued airworthiness are Size: KB.

Nowadays, structural modeling methods use a stratigraphic function that corresponds to the stratigraphic age to represent structural horizon, Caumon et al.Souche et al.

Introduction to Aircraft Structural Analysis, Second Edition, is an essential resource for learning aircraft structural analysis. Based on the author's best-selling text Aircraft Structures for Engineering Students, this brief book covers the basics of structural analysis as applied to aircraft structures.

Coverage of elasticity, energy methods, and virtual work sets the stage for discussions Book Edition: 2. Structural analysis involves three main phases, namely, modeling, analysis, and results processing. Computer software exists in order to automate the analysis and results processing phases. However, modeling is still done largely by hand, especially for frame structures.

This paper considers automated modeling of frame structures in the context of a computer integrated system for structural Cited by: 6. Comment: This is an ex-library book and may have the usual library/used-book markings book has hardback covers.
