Abstract

This paper investigates the potential benefits of utilising bifurcation analysis results in the planning and evaluation of piloted simulator trials of manoeuvrable aircraft, particularly when encountering nonlinear phenomena such as departure. Comparisons of bifurcation diagram predictions with piloted simulations are performed in order to validate the technique for application to realistic flight conditions. A close relationship is found between the theoretical and the experimental responses, and potential improvements in effectiveness of piloted test programmes are identified. Proposals for enhancing the predictive capability of bifurcation methods are made.
