Method of Improving Stability of a Highly-Loaded Axial Compressor Stage by Coupling Different Casing Treatments [PDF]
Casing treatment is a powerful method for improving the stability of aircraft compressors. An optimized slot-type casing treatment was tested on the first rotor of a highly-loaded two-stage compressor, and the results showed that the casing treatment ...

Delaying the Stall of A Low-Wing Aircraft Using A Novel Powerful Vortex Generator
In this study, a new aerodynamic surface concept is introduced, which is a powerful vortex generator (PVG). It can delay the stall point in a low-wing aircraft. This delay leads to a significant increase in the CLmax of an aircraft.

Boundary Layer Separation and Reattachment Detection on Airfoils by Thermal Flow Sensors
A sensor concept for detection of boundary layer separation (flow separation, stall) and reattachment on airfoils is introduced in this paper. Boundary layer separation and reattachment are phenomena of fluid mechanics showing characteristics of ...
