Abstract: Apparatuses, methods, and systems for generation of antenna tower structures are disclosed. One method includes receiving structure requirements of a tower, iterating a design of the tower, including selecting tower design features, determining a structural model from the structure requirements and the tower design features, defining an outline of the tower based on structure requirements and tower design features, defining nodal points of the design of the tower based on the outline, defining line-elements of the design of the tower based on the nodal points, performing low-order structural analysis based on the structural model and a modeled behavior assigned to the line-elements including determining a wind load for each line element, determining nodal displacements and material failure indices based at least on the wind load for each line element, and redetermining the structural model when the nodal displacements and material failure indices indicate failure.

Abstract: The present disclosure is directed toward methods, non-transitory computer-readable media, and systems for trajectory optimization in a high-altitude, long-endurance aircraft. For example, the systems described herein can generate an optimized flight plan for an aircraft during active flight of the aircraft by utilizing a greedy algorithm with buffering. In one or more embodiments, the systems described herein identify a plurality of possible states and select a predetermined number of the top possible states (based on energy change associated with transitioning to each possible state) at each incremental time period within a flight time window starting from an initial state to a plurality of possible states for a final incremental time period. Furthermore, in some embodiments, the systems described herein select a final state based on a final energy associated with the final state and determine a flight plan for the aircraft from the initial state to the selected final state.
