Variably positioned guide vanes for aerodynamic choking [PDF]
, 1974 A choking device to cause a sonic barrier to be formed which reduces the transmission of noise in a direction opposed to the direction of air flow in a compressor that may be part of an aircraft gas turbine engine is described.

Active clearance control system for a turbomachine [PDF]
, 1982 An axial compressor is provided with a cooling air manifold surrounding a portion of the shroud, and means for bleeding air from the compressor to the manifold for selectively flowing it in a modulating manner axially along the outer side of the stator ...

UNSTEADY STALL OF AXIAL FLOW COMPRESSORS [PDF]
, 1963 Abstract : Experimental study of the separation of a laminar boundary layer from walls moving upstream and downstream in a steady flow using a shrouded rotating cylinder in a wind tunnel was continued. Boundary layer velocity profiles were obtained over approximately half the range of angular positions on the cylinder which appear to be necessary in ...

International Journal of Aerospace EngineeringSmall gas turbine (SGT) engines power the latest generation of unmanned aerial vehicles (UAVs). This study investigates the axial flow–natured rotor blades of an SGT compressor. Rotor structures in axial flow compressors have failed due to complex stress
