Recent research on the effects of spanwise and streamwise aerodynamic gaps incorporated in a simple swept wing is presented. The wing flutter and gust response is
systematically investigated for a series of aerodynamic gaps. This paper presents the results of a systematic approach to modeling aerodynamic gaps in both the spanwise and streamwise directions of a simple swept wing. Forty different chordwise aerodynamic gaps and forty different spanwise gaps were examined. A process was employed that utilized ZAERO to zero the box pressures that simulate the aerodynamic gap. This process involved a MATLAB script to zero the pressures of the wing boxes that were in turn inputted to ZAERO for flutter and gust analysis. Lastly, the wing locations for maximum increase in the flutter speed and maximum decrease in wing root bending, root shear and root bending moment are presented.
