Performance, Stability and Control of Electric Short Takeoff and Landing Aircraft
… electric propulsion based on existing jet flap theory. The theory is advantageous for capturing the impact of propeller diameter on the lift augmentation. Corrections to the effective deflection angle of the jet based on the propeller size are developed. The modeling approach is …

Aero-propulsive characteristics of an overwing distributed electric propulsion system with vectored thrust
… of the vectored nozzle system in producing a jet-flap system, with varying induced circulation effects brought about by control of the nozzle deflection angle and the fan tip speed ratio.

Numerical Assessment of the Performance of Jet-Wing Distributed Propulsion on Blended-Wing-Body Aircraft
… a duct to spread out the exhaust flow to form a jet-wing or by using many small engines spaced along the span of the wing. Jet-wing distributed propulsion was originally suggested by Kuchemann as a way to improve propulsive efficiency. In addition, one can envision a jet-wing with deflected jets …

The Multidisciplinary Design Optimization of a Distributed Propulsion Blended-Wing-Body Aircraft
… to explain this. The formulation showed that the jet "fills in" the wake behind the body, improving the overall aerodynamic/propulsion system, resulting in an increased propulsive efficiency. The distributed propulsion concept also replaces the conventional elevons with a vectored thrust system …

Numerical Studies of Jet-Wing Distributed Propulsion and a Simplified Noise Metric Method
… of engine and aircraft. This concept is the jet-wing distributed propulsion idea, which redistributes the thrust across the span of the wings. Distributed propulsion is accomplished by using many smaller engines spread across the wings or several large engines to duct the exhaust flow in a …
