[기술논문] 중형급 항공기 동체 크기에 따른 항력 변화

The size of fuselage cross section is absolutely controlled by Market Requirement and Objective. Without a specific design criteria especially seat-abreast for the size of cross section designer can generate the various configurations. The proposed study was performed at the very early stage of aircraft design since the market did not sure what size of cross section should be proposed and its influence on aircraft performance. Three aircraft configurations are generated and the aerodynamic characteristics are evaluated by assuming the size of wing and empennage is identical.
