2Simulate: A Distributed Real-Time Simulation Framework

Abstract

Simulating large scale complex real-time systems requires enabling infrastructure for real-time co-simulation of various subsystems with complex behaviors and interfaces. AVES (Air Vehicle Simulator) is a reconfigurable flight simulator of the Deutsches Zentrum für Luft- und Raumfahrt e. V. (DLR) for research into rotorcraft and fixed-wing aircraft behavior. Complex models of aircraft subsystems in AVES required a distrib-uted real-time simulation framework. This paper presents 2Simulate, the enabling simulation infrastructure of the AVES facility that facilitates integrating a wide range of models and simulation hardware and software components. 2 Simulate is a unique simulation infrastructure being domain independent and methodology neutral. Its three components, 2SimCC, 2SimRT and 2SimMC, provide various capabilities including simulation control, task scheduling, model integration and hardware/software interfacing.
