Apparatuses and methods for the controlled trailing wake flows. An apparatus in accordance with one embodiment is directed to an aircraft system that includes an airfoil having first and second oppositely facing flow surfaces and a tip. The system can further include a vortex dissipation device carried by the airfoil, with the vortex dissipation device including a fluid flow nozzle, a valve device, and a controller. The fluid flow nozzle can be coupleable to a source of pressurized fluid and can include an orifice positioned to direct a flow of fluid out...


We claim: 1. An aircraft system, comprising: an airfoil having first and second oppositely facing flow surfaces and a tip; and a vortex dissipation device carried by the airfoil, the vortex dissipation device including: a fluid flow nozzle coupleable to a source of pressurized fluid, the fluid flow nozzle having an orifice positioned to direct a flow of fluid outwardly from the tip with a spanwise direction component; a valve device coupled in fluid communication with the fluid flow nozzle to selectively control the flow passing through the orifice; and...
