A Multiprocessor Avionics System for an Unmanned Research Vehicle.
Abstract
AFWAL/FIGL is developing a new Unmanned Research Vehicle (URV) testbed system for low cost flight testing of advanced flight control concepts. This new system will incorporate a modular/reconfigurable airframe, will possess greater aerodynamic capabilities, and will utilize an advanced avionics/control system to allow embedded computation of flight test applications. AFWAL/FIGL has utilized its in-house experience in multiprocessor systems technologies to develop a first phase prototype system comprised of multiple microprocessors and a parallel backplane bus. A multiprocessor software operating system and interprocessor communications protocol have been developed and tested. To demonstrate the capabilities of the system and the development of parallel software, an applications set of parallel software tasks have been developed and demonstrated. The hardware and software architecture, approach taken in the development, and results achieved are described in this report. Keywords: Multiprocessor, Unmanned research vehicle, Flight control, Operating systems, Microprocessors, Software development.
