Experimental validation of mathematical model describing external stores separation

This work is concerned with concepts and some results regardine the problem of aerodynamic interference in the system. The main emphasis is put on a practical, cost-effective engineering solution to this complex problem with reasonable computational efficiency allowing a code to run on PC computers. Prediction of separation trajectories of external stores is an important task in the aerodynamic design area having the objective to define operational release envelopes. To attain this purpose, a technique based on the Non-linear Panel Method with an unsteady free wake formulation has been developed. The comparison with a flight test as well as wind tunnel investigations has proved the reliability of this methodology.
