METHOD OF CREATING STRUCTURE ANALYSIS MODEL OF WING AND STRUCTURE ANALYZING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To create a three-dimensional structure analysis model of an actual wing by dividing a line passing measuring points between the front and rear edges of each measuring section into a fixed number of segments, and extending lines passing corresponding division points of each measuring section to defined planes. ;SOLUTION: About a plurality of measuring sections of an actual wing, the positions of a plurality of measuring points are acquired as measuring data, defined sections are set to the end and socket of the wing, and the front and rear end edge of the winding are detected each measuring section, based on the measuring data. About each measuring section, the line passing the measuring points between the front and rear end edges is divided into a fixed number of segments to create division points, and a line passing corresponding division points of each measuring section is extended to each defined plane to create a three-dimensional structure analysis model of the actual wing. This enables the direct structure analysis of the wing and allows the omission of the performance test in the design/development of a wing.;COPYRIGHT: (C)1999,JPO
