TL;DR: In this article, bifurcation analysis-based methodology is used in conjunction with a sliding-mode-based control algorithm to construct and simulate maneuvers for a nonlinear, 6 degree-of-freedom, F-18 high-alpha research vehicle aircraft model.

TL;DR: In this article, a 2D section of attainable equilibrium sets of a particular maneuver using an inverse trimming formulation is computed, and then the desired aircraft states are accessed from a normal flying condition, such as a level flight trim condition.

TL;DR: In this paper, the vertical tail sizing problem of a six-seater, light, business transport airplane is addressed by using constrained bifurcation analysis and continuation method, and a full six degrees-of-freedom nonlinear mathematical model is used for modeling the rigid body flight dynamics of the aircraft; aerodynamic stability and control derivatives required for stability analysis are estimated using standard empirical relations available in aircraft design textbooks.

TL;DR: In this paper, a constrained bifurcation analysis based procedure is used to determine the level flight and level turn steady states for an F-18/HARV model, and a Nonlinear Dynamic Inversion (NDI) based controller is designed to perform the closed loop simulation of a constant speed, level, coordinated turn maneuver from a straight and level flight to the maximum sustained turn rate flight conditions.

TL;DR: In this article , the authors present a review of technologies to decarbonize the production of ammonia, methanol, and ethylene, which together are responsible for about half of all greenhouse gas emissions from the chemical sector.
