The wing flutter and gust response is systematically investigated for a series of aerodynamic gaps This paper will present the results of a systematic approach to modeling aerodynamic gaps in both the spanwise and chordwise 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. The simulated aerodynamic gaps allowed the author to perform the eighty different analyses without physically modifying the aerodynamic geometry. |
