The Influence of Propeller Position and Size on the Aerodynamics of Blown Wings
… efficiency. By placing many motors along the wing leading edge, each powering a propeller, increased lift can be achieved by blowing high velocity jets over the wing. This allows the wing to be reduced in size, decreasing its cruise drag, whist still maintaining the same lift during take-off …

Rotor Wakes; Formations, Interactions, and Design
… (swirl) velocity, and wake vortex features on wing/body integration considerations. Using the integrated axial thrust across the same radial volume it was found that peak axial velocity across each propulsive device was within ten percent of the reference velocity using momentum theory of an …

An assessment of electric STOL aircraft
… which enable new vehicle configurations by allowing the efficient distribution of many smaller propulsors around the airframe. One application of this technology is to greatly enhance the short takeoff and landing (STOL) capability of a fixed-wing aircraft. STOL aircraft may have advantages over …

An Experimental Investigation of Blown-Flap Airfoils
… capabilities to fulfill this requirement, fixed-wing aircraft utilizing distributed electric propulsion (DEP) to enable blowing across their wings may be able to provide competitive performance while decreasing energy requirements for take-off and landing. In this thesis, the performance of …

Performance, Stability and Control of Electric Short Takeoff and Landing Aircraft
… One such arrangement is the electrically blown wing, where the slipstream of distributed, electrically-driven propellers arranged along the wing lead edge is used to enhance the wing lifting capability, enabling reductions in required field length or improvements in cruise efficiency …

An Experimental Investigation of the STOL Performance of Cal Poly's AMELIA in the NFAC
… incorporating leading- and trailing-edge blowing wing circulation control and over-the-wing mounted turbine propulsion simulators (TPS) to date. Testing of the 10 foot span model proved successful and was the result of a 5 year NASA Fundamental Aeronautics Program Research Announcement. The …
