POWER PLANT THRUST MANAGEMENT SYSTEM FOR TURBOPROP ENGINES

摘要

Methods and systems for operating a turboprop engine having a high pressurespooland a low pressure spool rotating independently from one another. Each spoolcontains at least one compressor stage and the low pressure spool is connectedtoa propeller. The method comprises determining a target temperature-correctedrotational speed of the low pressure spool for a given set of operatingparameters;and controlling a mechanical speed of the low pressure spool to maintain thetemperature-corrected rotational speed of the low pressure spool substantiallyconstant throughout at least a portion of a range of a power demand on theturboprop engine.
