Abstract

Abstract: Engine intake and exhaust have important influence on aircraft aerodynamic characteristics. To evaluate the aerodynamic characteristics of Blended-Wing-Body (BWB) aircraft with different overhanging engine layout modes, the numerical simulation technology of simulating the coupling between the intake and exhaust of the engine nacelle and the flow field of the aircraft is first carried out to verify the correctness of the calculation method. On this basis, a numerical simulation of the coupling between intake and exhaust of aircraft with different supporting heights, different streamwise and spanwise positions of the engine under the condition of aircraft cruising is carried out to evaluate the different layouts of the engine. The influence of different layout modes on the aerodynamic characteristics of aircraft is evaluated, and the regularity of the influence of different layout modes of engine is formed.

Key words: blended-wing-body, overhanging engine, nacelle, intake and exhaust, aerodynamic characteristics
