Paper Abstract

EADS/LFK-Lenkflugkoerpersysteme GmbH develops missile systems for a wide field of military applications. The Hardware-in-the-Loop (HWIL) facility of LFK in Unterschleissheim uses a five axis motion simulation table, an IR scene projection system and powerful simulation computers. The system is designed for test and evaluation of different missile programs fitting the dimensions of the five axis table and it's dynamic performance. Development, configuration management and maintenance of HWIL applications are time and cost consuming processes. Current missile programs are very complex and the development of modern missile systems has to be completed within short time intervals. Programming of HWIL as a test bench is getting a very complex and a high sophisticated task, which runs usually parallel to the missile development process. Programming of HWIL applications, despite physical missile models, means in the most cases low level programming of control loops, state machines, communication tasks, device drivers and integration of physical models. Hard requirements on the faultless functionality and on the accurate real-time behavior make the development and the test of HWIL software an ambitious and complex software development project. So new generation software development methods dealing with complex systems for HWIL applications are needed to shorten the development time, to lower the costs, to simplify the test and to reach a faultless functionality.
