Compressor Modeling for Engine Control and Maintenance

Abstract

This work describes a method for dynamically updating the compressor map for an advanced turbofan engine. The implementation of the method is illustrated using data from a transport aircraft powered by four turbofan engines. The compressor map is generated through projection pursuit regression and non-linear approximation, using Bernstein polynomial basis expansion regression. This approach allows for prediction options which would be useful to a controller algorithm. Results include the compressor maps and recommendations for implementing the proposed approach in an engine management system.
