Abstract: An aerodyne comprises a fuselage, a fixed wing , a thruster for cruising flight, and a rotary wing for stages of vertical flight and held stationary during cruising flight. The rotary wing includes at least two contrarotating single-blades disposed at the top of the fuselage and hinged about respective axes perpendicular to the rotor axes of rotation. A maneuvering procedure for maneuvering the aerodyne includes a transition stage between a stage of vertical flight and a stage of cruising flight, wherein in the transition stage, when the speed of each single-blade is less than a threshold speed of rotation, the pitch of each single-blade is such that it no longer provides any lift force and the transverse hinge of the single-blade to its rotor axis is held locked in a position such that the single-blade is perpendicular to the rotor shaft.

Abstract: Data is received that includes a multi-dimensional data set having data at different hierarchy levels. Using the received data, a first view of a chart having a branch corresponding to each dimension within the data set is rendered in a graphical user interface. Each branch extends outwardly from a center point and has graphical indicators corresponding to each corresponding hierarchy level. The hierarchy levels are arranged in order such that a highest hierarchy level is closest to the center point and a lowest hierarchy level is closest to or at a termination point of the corresponding branch. Related apparatus, systems, techniques and articles are also described.

Abstract: Examples of dynamic online energy forecasting are provided herein. An energy forecast request is received. An initial energy forecast is calculated in response to the request. One or more of a plurality of energy forecast model instances are selected as candidate forecast model instances. At least one of the candidate instances are transformed into an improved forecast model instance having greater accuracy than the candidate forecast model instance. The transformation is accomplished by determining alternative values for at least some parameters of an energy forecast model of the candidate forecast model instance. An improved energy forecast having a greater accuracy than the initial forecast can then be calculated using the improved forecast model instance.
