ABSTRACT:
A fully fixed, non-articulating geometry vehicle that includes a number of virtual control surfaces operable to replicate a mechanical control surface's functionality. These virtual control surfaces further include a number of flow control devices on the non-articulating vehicle surface. The plurality of flow control surfaces is operable to induce secondary flow structure(s) within a boundary layer of a fluid flow over the non-articulating vehicle surface. A virtual control surface controller is operable to dynamically adjust a frequency and amplitude of the secondary flow structure(s) in order to reposition the virtual control surface. A vehicle control and stability system communicatively coupled to the plurality of virtual control surfaces is operable to direct positioning of the plurality of virtual control surfaces in response to vehicle control commands.
