  • Patent number: 8949090
    Abstract: An apparatus for controlling the formation flight of a trailing aircraft relative to a vortex generated by a leading aircraft includes a position module, peak-seeking module, limiter module, and control module. The position module is configured to determine a position of the vortex relative to the trailing aircraft. The peak-seeking module is configured to determine a desired position of the trailing aircraft for providing desired vortex-induced aerodynamic benefits based on the position of the vortex relative to the trailing aircraft and a mapping function of an individual performance metric. The limiter module is configured to modify the desired position of the trailing aircraft to avoid unintended crossings of the trailing aircraft into the vortex. Finally, the control module is configured to control flight of the trailing aircraft based on one of the desired position of the trailing aircraft and modified desired position of the trailing aircraft.

  • Publication number: 20090319096
    Abstract: This disclosure is directed to methods, computer-readable media, and systems for controlling one or more uninhabited heterogeneous autonomous transport devices. Embodiments of the present invention advantageously reduce costs and improve efficiencies by providing capabilities for a computing device to be able to control and to monitor one or more heterogeneous autonomous transport devices. This occurs by generating a command signal from a computing device and transmitting the command signal to control on-board computing devices of one or more heterogeneous transport devices to execute requirements of a mission. Also, embodiments of the present invention provide ways to start-up, to send commands, and to shut down real or simulated heterogeneous autonomous transport devices.
