Evaluation and Experimental Validation of Low Costs CFD Based Mathematical Model Describing External Stores Separation

Abstract

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