Abstract
A propulsion system for an aircraft includes an engine, a plurality of sensors, and a controller. The engine includes an air intake. The plurality of sensors includes an outside air temperature (OAT) sensor and an air intake sensor. The OAT sensor is disposed outside the engine and configured to measure an OAT. The air intake sensor is disposed inside the air intake and configured to measure an air intake temperature (T). The controller is configured to: calculate an actual charge heating value (CHactual), compare the CHactual to a charge heating threshold value (CHthresh) to identify the CHactual is greater than or less than the CHthresh, identify a presence or an absence of an unusual engine performance condition for the engine, and identify a presence or an absence of a blockage condition of the air intake based on the CHactual greater than the CHthresh and the presence of the unusual engine performance condition.
