Abstract
This chapter discusses the effects of different wing tip devices on the aerodynamics of a swept wing. The choice of a wingtip device with a specific, required volume suited for an experimentally investigation is first discussed, followed by a detailed analysis of the wingtip flow. The flow analysis is based on numerical simulations of the RANS equations. The effects of the interaction between the wingtip and the wing on local flow separation and global aerodynamic wing loading are assessed. The results show that the design of the tip region has significant effect on the overall behavior—suited tip tanks can yield experimental configurations with useful high-lift behavior.
