Title:
Methods and systems for migrating air vehicles between crosswind and hover flights
Document Type and Number:
Japanese Patent JP6293939
Kind Code:
B2
Abstract:
A method may involve operating an aerial vehicle in a hover-flight orientation. The aerial vehicle may be connected to a tether that defines a tether sphere having a radius based on a length of the tether, and the tether may be connected to a ground station. The method may involve positioning the aerial vehicle at a first location that is substantially on the tether sphere. The method may involve transitioning the aerial vehicle from the hover-flight orientation to a forward-flight orientation, such that the aerial vehicle moves from the tether sphere. And the method may involve operating the aerial vehicle in the forward-flight orientation to ascend at an angle of ascent to a second location that is substantially on the tether sphere. The first and second locations may be substantially downwind of the ground station.
