Bifurcation Analysis of Longitudinal Dynamics of Generic Air-Breathing Hypersonic Vehicle for Different Operating Flight Conditions

The advancements in the Hypersonic Technology have taken us a step closer to the cost effective and reliable Hypersonic flight to Space. The paper outlines nonlinear dynamical model analysis of the Air-breathing Hypersonic Vehicle (AHV) using Bifurcation Method. It shows the Bifurcation Method implementation and its application to the nonlinear dynamics and stability investigation for 3DOF Longitudinal nonlinear dynamics of the Generic AHV. Bifurcation Analysis of AHV presents a quantifiable valuation with equilibrium states throughout the whole broad flight envelop and with dynamic stability analysis for Mach Number, M = 0.9. AUTO-07p platform is used here to demonstrate the AHV flight dynamics and control analysis using the Bifurcation Technique and Continuation approach. The Bifurcation Methodology is implemented for the AHV dynamic model using AUTO-07p for different operating flight conditions with elevator deflection, $${\delta }_{e}$$ .
