167 Ejector driven flow control for reducing velocity deficit profile downstream of an aerodynamic body US12723678 2010-03-14 US08690106B1 2014-04-08 Mark A. Reissig
A system and method for reducing a velocity deficit from an aerodynamic body is disclosed. An air jet is injected into an ejector mixing chamber in the aerodynamic body. The air jet creates a suction effect in the ejector mixing chamber, which suctions boundary layer air from a perforated surface in at least one side of the aerodynamic body into a plenum chamber and into the ejector mixing chamber. The air jet ejects the boundary layer air and the air jet from a trailing edge slot of the ejector mixing chamber. Suctioning the boundary layer air and ejecting the boundary layer air and the air jet from the trailing edge slot reduces a velocity deficit on a trailing edge of the aerodynamic body. The reduced velocity deficit and the suctioning of boundary layer air reduce noise, turbulence, blade stress, and blade deformation.
