This paper investigates the co-flow jet (CFJ) airfoils ability to further current aviation designs to be more environmental. With high cost and large contribution to carbon footprints, aeronautical designers look to drag reduction to decrease dependencies on fuel. Primary research on CFJ airfoils is led by Dr. Zha at the University of Miami. Through various forms of analysis, CFJ airfoils use a jet stream to create movement of air in the boundary layer region that helps create more lift reduce flow separation, thereby increasing stall margin and creates a thrust force. However, with further investigation, the magnitude of thrust created by CFJ components does not have sufficient evidence of enough force for a large commercial sized airplane, especially with takeoff. To definitely determine the possibilities for CFJ airfoil technology, more research will be needed. So far practical applications of CFJ can better improve current glider technologies for companies like NASA and Airbus and better engine integration for typical planes.
