Adaptive wing and flow control technology
TL;DR: In this paper, various conventional and novel means of boundary layer and flow control applied to moderate-to-large aspect ratio wings, delta wings and bodies with the specific objectives of drag reduction, lift enhancement, separation suppression and the improvement of air-vehicle control effectiveness are discussed.

The unsteady aerodynamics of slender wings and aircraft undergoing large amplitude maneuvers
Robert C. Nelson,Alain Pelletier +1 more
TL;DR: In this paper, the aerodynamic and the vortical flow structure over simple delta wings undergoing either a pitching or rolling motion are presented, and the importance of unsteady aerodynamics on the flight dynamics of aircraft maneuvering at large angles of attack is examined.

Flow Control over a Conical Forebody Using Duty-Cycled Plasma Actuators
TL;DR: In this paper, a tangentially-blowing surface-mount single-dielectric-barrier discharge (SDBD) plasma actuator is designed and implemented for the control of the vortex flow over a slender conical body at high angles of attack.

Boundary layer theory
TL;DR: The flow laws of the actual flows at high Reynolds numbers differ considerably from those of the laminar flows treated in the preceding part, denoted as turbulence as discussed by the authors, and the actual flow is very different from that of the Poiseuille flow.

Asymmetric Vortices on a Slender Body of Revolution
TL;DR: In this article, the symmetric and asymmetric leeward-side flow fields on an inclined ogive-cylinder were investigated using a number of experimental techniques and it was shown that micro-variations in the tip geometry of the model have a large influence on the downstream development of the flow field.

Onset of aerodynamic side forces at zero sideslip on symmetric forebodies at high angles of attack
E. R. Keener,G. T. Chapman +1 more
TL;DR: In this paper, the authors presented results from extensive wind-tunnel tests that include variations in axial and cross-sectional shape, fineness ratio, bluntness, strakes, and boundary-layer trips over a wide range of conditions (angles of attack to 90 degrees, angles of sideslip to 30 degrees, Reynolds numbers from subcritical to supercritical, and Mach numbers from 0.1 to 0.7).

Aerodynamic control using forebody blowing and suction
T. Terry Ng,Gerald N. Malcolm +1 more
TL;DR: Aerodynamic control using pneumatic forebody flow control was studied in this paper, where three methods of control were investigated: (1) blowing from a localized jet, (2) blowing in a slot, and (3) surface suction.
Development of non-conventional control methods for high angle of attack flight using vortex manipulation
TL;DR: In this paper, the effect of the size and location of the forebody strakes on the yawing moment of a generic fighter model was investigated and two schemes for vortex control on the fore body were evaluated: individually controlled tip strakes and individually controlled blowing ports.
