simulation is of crucial importance for system design and
optimisation. In aeronautics, simulation has been strong in the
area of flight dynamics and control. Modelling and simulation of
basic aircraft systems such as hydraulic systems also has a long
tradition, and the rapid increase in computational power has now
come to a point where complete modelling and simulation of all the
sub systems in an aircraft is possible.
There are several levels of design from requirement analysis and
system architecture down to detail design, and there is a clear
danger that systems engineering activities are performed only at
the top level of a design. In order to have an impact on the
product development process it must permeate all levels of the
design in such a way that a holistic view is maintained through all
stages of the design. This can be achieved if all design teams can
work towards a common system model where the subsystem designs can
be tested in an environment where the interaction with other
sub-system and the whole aircraft can be studied.
In this paper it is discussed how the actuation system control
surfaces can be simulated and optimised using a flight dynamics
model of the aircraft coupled to a model of the actuation system.
In this way the system can be optimised for certain flight
condition by "test flying- the system. The distributed
modelling approach used, makes it possible to simulate this system
much faster than real time on a 650 MHz PC. This means that even
system optimisation can be performed in reasonable
