초록

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.

청구항

A surge protected gas turbine engine for providing a variable flow of bleed air without operation near full load condition, comprising: a turbine wheel rotatable about an axis; a combustor for producing hot gases of combustion; means, including a nozzle, connecting said combustor and said turbine wheel such that hot gases of combustion impinge upon the turbine wheel to drive the same about said axis; a pair of rotary compressors coupled to said turbine wheel to be driven thereby, said rotary compressors each having an inlet and an outlet being connected ...
