A Critical Assessment and Requirement for Ground Testing on Vortex Breakdown Locations Over Delta Wings
Abstract
A critical assessment has been conducted on more than sixty experimental data sets about vortex breakdown locations over 650 and 700 delta wings at different angles of attack. Test conditions, such as tunnel wall and blockage, model support interference, model geometry and its deformation under load, as well as the methodology used to define breakdown location are examined. A screening process has been conducted to help identify the relative merits of the various data sets and to extract useful, quantitative information from the contradicting database. Aerodynamic and experimental requirements to ensure high quality data are discussed. The requirements for flow quality and data accuracy is farther raised.
