摘要： A general mounting method for ducted fan propulsors is disclosed. This mounting method uses extremely slender stators that connect the duct ring to the propulsor which is mounted in the middle and drives the rotor, fan or propeller. The slender stators take the form of spokes and as such are so slender that the midspan stresses within the spokes are dominated by axial tension loads rather than the shear loads experienced by conventional stators. The spokes may have an aerodynamic shape and damping methods may be used to retard spoke vibrations and transmission of engine vibrations to the duct and force. The duct itself is also stiffened by the spoke arrangement, thereby reducing low frequency vibration modes.

摘要： Disclosed herein are example embodiments for unoccupied flying vehicle (UFV) location assurance. For certain example embodiments, at least one machine, such as a UFV, may: (i) obtain one or more satellite positioning system (SPS) coordinates corresponding to at least an apparent location of at least one UFV; or (ii) perform at least one analysis that uses at least one or more SPS coordinates and at least one assurance token. However, claimed subject matter is not limited to any particular described embodiments, implementations, examples, or so forth.

摘要： An apparatus comprises a base vehicle, a takeoff and landing system, a rack system, a refueling system associated with the base vehicle, and a controller. The rack system comprises a group of racks with slots in which the slots receive unmanned aerial vehicles, provide refueling connections that facilitate refueling of the unmanned aerial vehicles located in the slots, and provide data connections that facilitate data transmission with the unmanned aerial vehicles located in the slots. The refueling system refuels an unmanned aerial vehicle located in a slot using a refueling connection in the refueling connections. The controller communicates with the unmanned aerial vehicle using a data connection and control the refueling of the unmanned aerial vehicles by the refueling system while the unmanned aerial vehicle is in the slot, enabling exchanging data with the unmanned aerial vehicle and the refueling of the unmanned aerial vehicle simultaneously.
