Hydraulic System Simulator Model For Boeing 777

To optimize the hydraulic system design and evaluate the system performance at the airplane level, a complete dynamic integrated hydraulic model is needed. This paper describes the development and usage of a dynamic model for the Boeing 777 hydraulic system. This model dynamically simulates the hydraulic power available as a function of the airplane events. This not only allows the designers to test their design prior to building the hardware but it also serves as a tool to evaluate the hydraulic system performance at the airplane level.
