초록

The present invention provides a system and method for actively manipulating and controlling aerodynamic or hydrodynamic flow field vortices within a fluid flow over a surface using micro-jet arrays. The system and method for actively manipulating and controlling the inception point, size and trajectory of flow field vortices within the fluid flow places micro-jet arrays on surfaces bounding the fluid flow. These micro-jet arrays are then actively manipulated to control the flow behavior of the ducted fluid flow, influence the inception point and traje...

What is claimed is: 1. A method to manipulate shedding of flow field vortices from an external aerodynamic surface of an aircraft, comprising: placing a plurality of micro jets at the external aerodynamic surface, wherein the micro jets are oriented at an acute angle to a mean flow direction of a fluid flow; inducing secondary flow structures within a boundary layer of the fluid flow with the micro jets at the external aerodynamic surface, wherein the secondary flow structures manipulate the shedding of flow field vortices from the external aerodynamic ...
