Research flight control computer development for the flight control switching mechanism

The flight control switching mechanism system (FCSWMS) can give a pilot-selectable research control law capability due to the research flight control computer (RFCC) and the basis triplex primary flight control computer (PFCC), therefore this system provides a flexible platform for control law algorithm research. The research flight control system (RFCS) supports a design capability for relatively fast control law modifications and development, while retaining safety of flight through the PFCC. The RFCS processor was designed by more improved performance than primary FCC processor for the implementation of switching algorithm on the FCSWMS. The application software based on VxWorks operating system was developed on the tornado development environment. The verification and validation of research flight control computer system and software was performed in the hardware-in-the loop simulation environment including the primary flight control computer, cockpit and etc.. The RFCS verified through the software and system test will be useful for a variety of advanced control law research and future flight control system development.
