Adaptive Vehicle Management Systems Phase I Overview

摘要

Decades of flight controls and vehicle management system technology development have focused on therndevelopment of full authority digital flight control systems. More recently, efforts have begun to focus onrndeveloping capabilities that more fully exploit such flight control systems, making use of more of the informationrnavailable on a modern rotorcraft system, and integrating multiple features and functions together into suites ofrntechnologies. The Adaptive Vehicle Management System (AVMS) program was created to identify andrndemonstrate technologies and develop the framework of an adaptive vehicle management system – a vehiclernmanagement system that maximizes system performance by utilizing all available information across all subsystemsrnand reacts to maintain performance even under anomalous/degraded conditions. This paper presents the results ofrnthe two-year first phase of the AVMS program, which explored many technologies and included flight testing of thernAVMS technology suite on the Boeing H-6 flying testbed aircraft. A methodology for prioritizing and selectingrncomponent technologies is described, followed by a detailed description of the work performed to investigate andrndevelop several of the component technologies. Specifically, the technologies discussed in detail in this paper arerntactile cueing for mission aiding, torque management VMS solutions, tactile cueing for legacy mechanical controlrnsystems, external load active stabilization, and adaptive control technology. Overall, the AVMS Phase I programrnshowed that many advanced vehicle management functions can be combined in an integrated design to deliver arnbroad range of performance benefits, with tactile cueing proving to be an important enabling technology that allowsrna pilot to intuitively interact with a large number of modes and functions.
