Dynamic constrained low altitude flight maneuvers with constant energy

摘要

This paper introduces the so called Energy Constant Trajectories (ECT) for low-level flights as well as trajectory planning in TF/TA maneuvers in mountainous areas. A typical ECT is developed thru incorporating terrains as some constraints into the dynamics of the flying aircraft. This strategy leads to an identifier for the control variable boundaries which in turn, simplifies the optimum decision making process. In fact, the dynamical system reduces to a constrained control variable problem for a significantly simpler system which considers only the kinematic equations of motion. Numerical results for an arbitrary 3/D flight show that this approach improves the reliability of the guidance law that needs to be followed by the aircraft over a given terrain.
