Abstract: This paper presents a transient three-spool turbofan engine simulation model that uses a combination of intercomponent volume and iterative techniques. The engine model runs in real time and has ...

Abstract: High aspect ratio flexible wings are of increasing interest for enhancing the aerodynamic efficiency of future designs. However, they often exhibit nonlinear dynamic behavior, complicating both testing and analysis. This ...

Abstract: The problem of horizontal-plane tracking control of an omnidirectional, four vectored-thruster aerostat subjected to actuator failure is considered. The actuator failures result in the aerostat’s becoming underactuated, ...

Abstract: This paper proposes a nonlinear disturbance observer (NDO)–based sliding mode control (SMC) method to the problem of stall flutter suppression for a revised Leishman–Beddoes (L–B) model. To capture accurate aerodynamic ...
