Abstract:
Experiments have been carried out in a wind tunnel in order to study the aerodynamics ofafterbody vortex flows pertinent to cargo aircraft with upswept afterbodies. The overallaim of the study was to understand detailed vortex flow physics, to examine passive flowcontrol methods for drag reduction, and to examine the flowfield with the cargo rampdoor deployed. The simplified wind tunnel models were axisymmetric slanted base cylinderswhich have previously been utilised for afterbody vortex flow generation and weretested at ReD = 200; 000. Drag force, 2D Particle Image Velocimetry (PIV) and surfacepressure measurements were conducted along with detailed flowfield analysis of PIV dataincluding unsteady aspects of the flow.
