Abstract

A method for correcting the UVLM based on a downwash correction is presented. This is compared to the equivalent correction approach using DLM. The methods are compared for predicting the loads due to encounters with "1-cosine" gust defined by the CS-25 requirements. Two configurations are investigated. The first is a high altitude UAV wing and the second case is the NASA Common Research Model. Results are presented for both rigid and aeroelastic simulations and compared to full CFD results.
