Aircraft System Simulation for Preliminary Design

Conference: 28th International Congress of the Aeronautical Sciences


Developments in computational hardware and simulation software have come to a point where it is possible to use whole mission simulation in a framework for conceptual/preliminary design. This paper is about the implementation of full system simulation software for conceptual/preliminary aircraft design. It is based on the new Hopsan NG simulation package, developed at the Linköping University. The Hopsan NG software is implemented in C++. Hopsan NG is the first simulation software that has support for multi-core simulation for high speed simulation of multi domain systems. In this paper this is demonstrated on a flight simulation model with subsystems, such as control surface actuators.

    ABSTRACT: In aircraft design a critical part of the design is the engine selection. This is typically making a selection from exiting engines. Looking at a next generation future fighters, however, where the time of deployment may be 20-30 years in the future this is not a valid approach as there will be an evolution in the engine designs. E.g. a new European fighter aircraft will most likely be a collaborative project also involving the development of an engine for that aircraft. In this study conceptual engine-airframe co-design is demonstrated, using models of comparable fidelity for both the engine design and the aircraft design. This co-design leads to a deeper understanding of the tradeoffs from both sides, and means that also more radical designs and innovations can be evaluated in a fair way.
