Aircraft Systems Simulation
Simulation of aircraft systems has been an area of interesst for a long time at the division, starting with system simulation of the Gripen hydraulic system in the 90ties. In recent year the focus has been moved also to other areas and to whole aircraft simulation and optimisation also for use in the early conceptual design phases. System simulation is a central tool in current aircraft system design. Simulation during conceptual design are used for:
- system architecture development
- system performance analysis (with focus on energy consumption)
- fault tread analysis (FTA) by simulation: failure modes and derated system performance
- cross-coupling effects between different (sub-)systems (both positive and negative)
Especially on military aircraft design with its highly integrated systems, multidisciplinary system simulation becomes more and more important. Civil aircraft design manufacturers are on the way to change to simulation based product aquisition, this means that the application of a supplier is an executabel simulatation model that the manufacturer can include in his (whole aircraft) model. This requires complex and advanced sub-simulation or meta-simulation environments like developed in the European CRESCENDO project.
At the division simulation is performed using the in-house simulation software HOPSAN which has unique capabilities for high-speed simulation of large scale systems. Dymola is another software used in some particular areas.
