Stall propagation in axial compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
A theory of stall propagation in a cascade of airfoils of high solidity has been developed which includes the effects of finite blade chord and of the boundary layer response to changes in angle of attack. The theory is ...
A cascade tunnel for investigation of rotating stall
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1954], 1954)
A test apparatus which will reproduce the rotating stall phenomenon found in axial compressors has been constructed and installed in the main wind tunnel circuit of the Gas Turbine Laboratory. The test section consists of ...
Active control of rotating stall in axial compressors
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1992], 1992)
An active control system has been implemented on a low-speed single-stage axial compressor. This control system stabilizes the perturbations which normally lead to rotating stall, thus extending the range of operation of ...
Effects of compressor endwall suction and blowing on stability enhancement
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1988], 1988)
An experimental investigation was carried out to examine the effects on stall margin of flow injection into, and removal out of, the endwall region of an axial compressor blade row. A main goal was to identify the mechanism ...
Stall propagation in a cascade of airfoils
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1956], 1956)
An experimental investigation of stall propagation in a stationary circular cascade by means of high speed schlieren and interferometer photography is described. This investigation suggests an analytical approach to the ...
Dynamic control of rotating stall in axial flow compressors using aeromechanical feedback
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1993], 1993)
Dynamic control of rotating stall in an axial flow compressor has been implemented using aeromechanical feedback. The control strategy developed used an array of wall jets upstream of a single stage compressor which were ...
Active control of rotating stall in a three-stage axial compressor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1993], 1993)
Stall inception in a three-stage axial compressor has been suppressed over a range of previously unstable operating points through the feedback of velocity perturbations to the inlet flow field. Perturbations were generated ...
An investigation of rotating stall in a single stage axial compressor
(Cambridge, Mass. : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1955], 1955)
The rotating stall characteristics of a single stage axial flow compressor were investigated. The number of stall cells and their propagation velocities were found with and without stator blades. The measured velocities ...
