摘要： A hierarchical modular arbitration architecture for a mobile platform guidance system is disclosed. In embodiments, the architecture comprises a hierarchy of arbitration layers, each arbitration layer narrower in scope than the layer above (e.g., mission objective arbitrators, route arbitrators, path arbitrators). Each arbitration layer includes one or more objective-based arbitrators in communication with one or more applications or modes. Each arbitrator receives control input (e.g., from the pilot, from aircraft sensors) and control signals from the level above, selecting a mode to make active based on decision agents within the arbitrator layer which control mode priorities and sequencing (e.g., some flight objectives may involve multiple arbitrators and their subject applications coordinating in sequence). Each arbitrator passes control signals associated with fulfilling the commands of the active mode to the level below and reports application and error information to the arbitrator level above and/or human/artificial pilot machine interfaces.

摘要： A system and method for automated vertical takeoff and landing (VTOL) aircraft emergency landing is disclosed. The system receives a plurality of inputs from onboard modules including aircraft state, vehicle health, acceptable landing zone (LZ), emergency landing path, and 3D world model to prepare an emergency landing procedure when necessary. If functional onboard an unmanned VTOL aircraft, the vehicle health module determines an emergency landing requirement, the system commands a damage tolerant autopilot to perform the emergency procedure and automatically control the VTOL aircraft. If functional onboard a manned VTOL aircraft, an operator or the vehicle health module initiates the emergency landing. Regardless of initiation, the emergency landing system controls, or provides guidance for manned control of, the VTOL aircraft from the point of initiation through touchdown at a threat differentiated preferred LZ via failure-based flight control inputs for automatic landing, or autonomous autorotation entry, glide, and flare.
