Assessment and Comparisons for a UCAV Wing Design

摘要

This paper describes the aerodynamic design and assessment of a UCAV wing developed under the NATO-STO AVT-251 Multi-disciplinary Design Task Group. The wing design rationale and process is described as well as how theidealized wing design produced by the wing design/optimization process is turned into realizable aircraft geometry.Both the baseline and designed wings are analyzed in detail using several Navier-Stokes computational fluid dynamicsflow solvers. Analysis at low speed and transonic conditions both in the pitch plane and at sideslip conditions ispresented. Conclusions about the design are drawn and further improvements are suggested.
