Abstract
This paper conducts a conceptual design study of the use of CoFlow jet (CFJ) control surface technology on a Boeing 787-8 Dreamliner to allow for high surface control authority with a reduced empennage size. The study evaluates performance metrics of a baseline Boeing 787-8 model and compares the data to the calculated performance and dimensioning of an aircraft with CFJ integrated control surfaces. The study shows the baseline aircraft model validations are in good agreement with published data. The study results show a significant weight and drag reduction on the overall aircraft, with a gross overall weight reduction of 10.24%, and a total drag reduction of 4.65% All these benefits result in an increase of 4.88% of C-L/C-D and a fuel weight reduction of 12.97%. The conceptual study of this paper shows that CFJ-implemented empennage design appears to be a promising technology to substantially reduce the fuel consumption and emission pollution of transonic transports.
