Transient Turbine Engine Modeling with Hardware-in-the-Loop Power Extraction (PREPRINT)
Abstract
Increasingly high aircraft power demands require that the interactions between an aircraft's electrical subsystem and the engine subsystem be considered in dynamic, system-level tests. Traditionally, system-level dynamics have only been captured in completely assembled aircraft systems. Component-level or subsystem-level optimization is no longer appropriate because highly interdependent dynamics between subsystems only become apparent during system-level analysis. In an effort to mitigate program risk, enable system-level optimization, and reduce the high cost of testing integrated power and propulsion systems in an altitude-simulating wind tunnel, alternatives such as modeling and simulation can be utilized. Synchronizing and coupling simulations of vastly different time scales is possible; however, the resulting system simulation usually runs very slowly. For this reason, hardware-in-the-loop (HIL) is an ideal test platform where simulations and hardware components can be integrated for system-level testing when time scales are drastically different or actual hardware prototype components are available.
