Abstract

The market demand on business jets is growing fast. The Blended-Wing-Body (BWB) configuration is adapted to design high-efficient green business jet. Conceptual study of the BWB-type transonic business jet is carried out. The BWB-type business jet expected to provide a better cabin space and aerodynamic performance to compare with the conventional business jet. An aerodynamic analysis of the BWB-type transonic business jet is performed to understand the flow field around the aircraft at a high subsonic flight speed. The commercial CFD (Computational Fluid Dynamics) code, ANSYS Fluent, is used for aerodynamic analysis. A parametric study is carried out to analyze the relation between the design parameters and aerodynamic characteristics. The commercial PIDO (Process Integration and Design Optimization) tool, PIAnO, is used to perform a parametric study. As a result of parametric study, the sensitivity of the design parameters is analyzed and a proportion of aerodynamic influence of each design parameter is presented. One of the sample design configurations for detailed aerodynamic analysis is selected. As a result of the aerodynamic analysis, aerodynamic coefficients and pressure coefficient distribution around the BWB-type business jet are presented. Increase of AOA and Mach number produces stronger shock and drag coefficient is increased due to wave drag.
