Modeling and simulation of a multi-functional high-lift actuation system based on key performance data

Abstract

The rising complexity of flight control systems leads to a huge amount of additional testing. A major quantity of malfunctions is identified during system integration activities at a late stage in the development process. In order to reach high maturity as early as possible especially on the overall system level, virtual testing methods become increasingly important. This paper describes the development of a flight control actuation systems library based on key performance data. The library is implemented in the modeling language Modelica and enables the simulation and analysis of state-of-the-art high-lift actuation systems including the main mechanical failure cases. In addition, a script-based preprocessing is implemented that minimizes the parameterization effort for different test cases.
