Numerical Investigation of the Flow Around a Fuselage/Canard Configuration for a Long Range, Ultra High Capacity Aircraft

Abstract

Within the scope of the development of a long range, ultra high capacity aircraft (UHCA) at Airbus Industrie also the application of a three surface configuration including a front fuselage canard is discussed. Therefore as a contract work for Airbus Industrie at DLR a numerical study concerning the flow around a fuselage/canard configuration has been performed with the aim to prove the aerodynamic feasibility of such a configuration especially in the high subsonic Mach number range. The fuselage geometry and canard planform has been given by Airbus Industrie as well as the geometrical constraints and the aerodynamic conditions. The investigations have been done using the DLR Euler code CEVCATS developed for the analysis of inviscid compressible flow. In the first part of the study the flow field of the front fuselage has been analyzed in detail.
