Title: Direct Simulation Based Optimization for Aircraft Design Including Systems
Abstract: Modelling and 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. In this paper sizing, flight dynamic and hydraulic systems have been simulated and optimised in the same loop. It is discussed how high angle of attack aerodynamic including dynamic effects and 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, high angle of attack aerodynamic and sizing are taken into account. In this way the system can be optimised for certain flight condition by ”test flying” the system during the sizing of the aircraft.The distributed modelling approach used, makes it possible to simulat faster than real time on a standard PC. This means that even system optimisation can be performed in reasonable time.
