A New Simple Analytical Model for Flow Analysis over Slender Delta Wings

A simple analytical model is presented for determining the position and strength of the vortices over a slender delta wing at moderate to high angles of attack. The model is based on the inviscid incompressible flow theory. The slender wing assumption is a cornerstone of the current study on which the validity of the results depends. The lift force of the wing can be calculated using this simple analytical model. Comparison of the predicted lift coefficient results with the available experimental findings shows satisfactory agreement with slender wings, AR :s 1. The method is currently applied with some revision to higher AR delta wings and the results will be presented in our future work.
