When modeling an aeroengine control system, effects of fuel metering unit are neglected or oversimplified, which most probably leads to unreliable simulation or experimental results. In order to well understand influences of fuel metering unit on performance of an aeroengine and to enrich the component-level model of a turboshaft aeroengine, a stepping motor controlled fuel metering unit is examined by combining process-based modeling and object-oriented modeling and is employed in the component-level engine model. Performances of the engine with and without the fuel metering unit are compared by simulation. The component-level engine model with the fuel metering unit characteristics considered meets the simulation requirements on the steady precision and can describe dynamics of the engine more precisely. A semi-physical experimental verification is implemented to confirm the influence of the fuel metering unit. The results show that simulation using the component-level engine model with the fuel metering unit sub-model is in accordance with the experiment, and that comparing to the engine model without fuel metering unit, the model with a fuel metering unit can extend the performance parameter response dozens of milliseconds.
