Abstract:
A load applied to a low pressure spool of a two-spool turboshaft engine is controlled responsive to inlet pressure and temperature so as to regulate a relationship between the rotational speeds of the low and high pressure spools of the two-spool turboshaft engine so as to provide for operating the low pressure compressor attached to the low pressure spool with sufficient surge margin.
