Development of an Integrated Structural Analysis Capability for Airframe Preliminary Design

摘要

This paper highlights a preliminary airframe structural analysis capability for evaluation of candidate wing structural designs, with the goal of producing accurate weight and recurring cost data from high level airplane design data. SPANDSET, the integrated structural analysis toolkit that implements this capability, allows rapid definition of wing geometry, calculation of internal loads, preliminary analysis of wing structural elements and recurring cost evaluation of the candidate design. A case study involving a large business jet aircraft is documented to illustrate the approach and the types of results that can be obtained.
