Nonlinear Flight Dynamics Problems: Analysis and Control Design

Prof. Mikhail Goman (De Montfort University and TsAGI, Russia)

Aircraft flight dynamics become nonlinear during energetic spatial maneuvering and entering the critical flight conditions such as stalling, spinning or autorotation regimes. Inertia, kinematic and aerodynamic coupling of different aircraft rigid body modes of motions require nonlinear mathematical models for thorough dynamics investigation. Special impact to an aircraft nonlinear behavior is generated by nonlinear aerodynamic effects due to flow separation and vortical flow at high angles of attack.

Attention will be focused on the application of qualitative and bifurcation methods for analysis of aircraft nonlinear dynamics and design of control laws for departure prevention and spin recovery, as well as to assessment of any controllers designed using linear mathematical models. The qualitative methods and numerical algorithms for their application will be discussed. The presentation is accompanied by the results of nonlinear dynamics analysis and control design revealing the nature of the problems considered.
