Estimation of Thrust Augmentor Performance in V/STOL Applications 872323

The performance of two-dimensional thrust augmentors was analyzed by a viscous-inviscid approach, where distinct zones of the augmentor flow-field were treated with efficient methodologies, and are then matched together by satisfying required pressure and velocity continuity at zone interfaces.
This efficient approach was applied both to a parametric analysis of a standard ejector configuration, where various shroud parameters for arrangements with one or two primary nozzles were considered, and to a limited constrained optimization analysis of inlet shape and nozzle location for a single primary nozzle arrangement. The methodology was validated by quantitative and qualitative comparison with experimental results, and the study provided new insights into thrust augmentor performance as well as practical design guidelines.
