Computer-aided Engineering for the Design of Flight Control and Hydraulic Systems
نویسنده
چکیده
Generic, ready-to-use preliminary design methodologies for aircraft utility systems, made available by means of a Computer Aided Engineering (CAE) tool do not exist. An attempt is made to apply principles used in preliminary aircraft design to preliminary design of utility systems. This is demonstrated for the flight control and hydraulic system. The Computer-Aided Engineering tool consists of independent modules that build on each others results. For the programming of each of these modules it was necessary to thoroughly review the state of the art. This paper presents one module in more detail: the module for steady state calculation of hydraulic systems. This module provides key information for aircraft hydraulic system design. It is based on the Linear Theory Method with pq-equations and supports the incorporation of aircraftspecific hydraulic components into the calculation.

Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...
