摘要

Rotorcraft used by the US military today are flying longer and performing more diverse missions than their originalrndesigners ever intended. Tight budgets have limited the procurement of new systems, so military services keep theirrnexisting fleets operating through numerous modernization and service life extension programs. The federatedrnarchitecture employed in most legacy systems constrains how much can be accomplished in a given upgrade, sincerneach aircraft function is typically performed in a separate line replaceable unit. Throughput and memoryrnmanagement features of a modern processor, together with an operating system that provides strict partitioningrnbetween different software applications offer a means of safely integrating different functions of varying criticalityrninto one computer. These technologies, when coupled with an open architecture approach, enable the creation of arncore integrated system capable of performing flight control, weapon delivery, navigation, and a host of other utilityrntasks, while offering tolerance to obsolescence issues. Consequently, the scope of an aircraft upgrade can bernexpanded without a proportional increase in cost. BAE SYSTEMS Controls (Controls) teamed with Sikorsky tornverify the feasibility of these concepts for the Applied Aviation Technology Directorate’s Rotorcraft VehiclernManagement System program. The Controls team demonstrated a flexible, partitioned control system built from offthe-rnshelf modules in a real-time pilot-in-the-loop rotorcraft simulator. The effort included packaging the existingrnvehicle control laws and several non-critical support functions as separate application partitions and hosting them onrna single microprocessor. Dynamic simulations in a variety of configurations verified the legacy code wasrnsuccessfully imported, while highlighting the flexibility of the system architecture. The demonstration alsornconfirmed the integrity of the partitioning mechanism through its ability to reject software errors that werernintentionally injected into the non-critical applications. The laboratory results indicate that highly integrated systemsrnare practical with current technology and offer a potential solution to the upgrade needs of today’s militaryrnrotorcraft.
