摘要

Developments in computational hardware andrnsimulation software have come to a point wherernit is possible to use whole mission simulation inrnthe preliminary design. This paper addressrnsome key issues needed to realize this. Thesernare, system simulation using distributed solversrnfor robust large scale simulation, time scalerncompression to deal with the widely differentrntime scales involved, e.g. the transientrnbehaviour of control surface actuators, to therntracking of fuel consumption. The application isrna flight simulation model with subsystems suchrnas control surface actuators. In this way it isrnpossible to do real time simulation (RTS) andrnfaster than real time simulation (FRTS) ofrnrather complex systems.rnUsing such models it is possible to dorndesign analysis, e.g sensitivity analysis andrntrade of analysis, as well as design optimisation,rnIn this paper this is demonstrated on a flightrnsimulation model with subsystems, such asrncontrol surface actuators.
