Modeling and simulation of an aircraft’s hydraulic distribution system based on a LMS Amesim® Model and a Bond Graph support

Resumo

This paper presents two different and complementary modeling techniques to analyze the main char-
acteristics of hydraulic systems and identify potential failure scenarios. To assess the behavior of system relevant

variables the LMS Amesim® was used and a dashboard was developed to enhance the post simulation analysis of
the aircraft operation. As a study case, a typical commercial aircraft hydraulic architecture was modeled and some
failure scenarios were studied, such as single engine failure during take-off, complete propulsion system failure
during the flight, and also a normal landing operation. In parallel, a bond graph diagram representing the system
components is developed as a support tool to provide a more detailed understanding of the modeled physics.
