ABSTRACT:
Surge protection is achieved in a turbine engine intended to provide varying quantities of bleed air and having two compressor stages (48, 36) by providing the inlet (56) of the first stage (48) with variable inlet guide vanes (58, 60). The first stage compressor (48) is a high specific speed, single stage centrifugal compressor whose stable operating characteristics are highly sensitive to inlet guide vane geometry, thereby allowing variations in such geometry to be employed to prevent compressor surge.
