Abstract


In order to research and engineering applications to teaching aircraft design , aircraft design method provides a convenient computing environment . In this paper the application of object-oriented programming techniques , CATIA secondary development technology , multi-disciplinary integration and optimization platform iSIGHT , developed an aircraft conceptual design and optimize computing environment . The completion of the research work , including : 1) First, the computing environment of the aircraft conceptual design system framework of planning , expounded the basic principle of the system framework , clear the function of each module in the aircraft conceptual design computing environment . 2 ) the boundaries line method in the application of aircraft design , the preparation of the main parameters of the aircraft preliminary estimation module ; calculated according to the aircraft conceptual design stage , the preparation of the aircraft conceptual design aerodynamic , weight , thrust system , and performance analysis module ; application CATIA secondary development of technology , the preparation of the three-dimensional shape of the aircraft conceptual design phase of aircraft generation module . 3 ) in accordance with the framework of the system of the aircraft conceptual design computing environment , integration module, module of the thrust system performance analysis module , as well as aircraft three-dimensional shape the aircraft preliminary estimate of the main parameters module , aerodynamic analysis module , weight generation module, developed the conceptual design of an aircraft environment, and with a typical aircraft conceptual design examples are given to illustrate the feasibility of the computing environment developed in this paper . 4 ) will be prepared by the aerodynamic analysis module weight module, module of the thrust system performance analysis module integrated into the multi-disciplinary integration and optimization platform iSIGHT aircraft concept optimization design environment . Aircraft conceptual design developed and optimized computing environment can be applied not only to the teaching of the overall aircraft design , and can be applied to aircraft conceptual parameter robust optimization and overall design approach of the aircraft family ( series ) , the reference value for engineering applications .
