Axial compressor stall.
… the experimental investigation of rotating stall in compressors of high hub-tip ratio. Measurements were obtained in builds of one to four stages, covering a wide range of design flow rates and also a change in design reaction. The purpose of the experimental work has been to gain a better …

Effects of temperature transients on the stall and stall recovery aerodynamics of a multi-stage axial flow compressor
… effects of inlet temperature transients on the stall and stall recovery aerodynamics of a low speed multi-stage axial flow compressor has been presented. Experiments were conducted on a low speed multi-stage axial flow compression system to demonstrate how a compressor dynamically stalls or …

Unsteady flow physics of airfoil dynamic stall
… the flow perturbations, for a canonical dynamic stall process. A series of unsteady surface pressure measurements, with a high sampling frequency, were acquired in order to investigate the time-dependent behavior of the flow in the immediate vicinity of the airfoil. These surface pressure …

Post stall propeller behavior at low Reynolds numbers
… data exists for propeller and wind turbine post stall aerodynamics. Post stall aerodynamics was observed in small propellers at low Reynolds numbers. First, performance data (thrust, power, and efficiency) of set variable pitch propellers was acquired in a wind tunnel. The propellers were 6 to …

Robust post-stall perching with a fixed-wing UAV
… complicated fluid flow, the animal exploits post-stall pressure drag to rapidly decelerate and land on a perch with a precision far beyond the capabilities of our best aircraft control systems. In this thesis, I present a controller synthesis technique for achieving robust, post-stall perching …

An Experimental Study of Unsteady Flow Over Airfoils Near Stall
… not exhibit low-frequency unsteady behavior near stall and the resulting lift fluctuations were very small (less than 0.040). These airfoils exhibited trailing-edge separation which moved forward on the airfoil as the angle of attack was increased into stall. The separation was not uniform along …
