AIRCRAFT DESIGNING METHOD, AIRCRAFT DESIGNING PROGRAM AND AIRCRAFT DESIGNING APPARATUS

摘要

An aircraft designing apparatus receives set values of design parameters related to the shape of an intake duct, creates analysis models for an aerodynamic characteristic analysis and a radar-cross-section analysis by using the values of the design parameters, calculates aerodynamic characteristics and radar-cross-section characteristics of the intake duct, and determines whether or not this analytical result satisfies a preset design condition. If it is determined that the analytical result does not satisfy the design condition, the values of the design parameters are updated. The updating of the design parameters, the analyses of the aerodynamic characteristics and the radar-cross-section characteristics, and the determining process are repeated until it is determined that the analytical result satisfies the design condition.
