Abstract

The performance of the Standard Cirrus glider is simulated using a Computational Fluid Dynamics code, solving the incompressible Navier-Stokes equations for steady flow. To calculate the transitional boundary layer flow a correlationbased transition model is used. It is found that the numerical model is able to predict the performance of the Standard Cirrus well. The simulations using the transition model are found to improve the results compared to fully turbulent simulations, except for the region of the stall. The best in-flight measured glide ratio for the Standard Cirrus is 36.5 at 94.5 km/h. The simulations using the transition model predict a best glide ratio of 38.5 at 95 km/h.
