Minimization of Wing Deformation in Trimmed Flight of Highly Flexible Aircraft Using Multiple Control Surfaces

摘要

A methodology is presented for performing trim optimization in highlyexible aircraft congurations by incorporating redundant, multiple con-trol surfaces positioned on the trailing and leading edge of the wing,in order to minimize wing deection. It employs the simplex linearprogramming algorithm, and compares three dierent control surfacecongurations. The benecial results from using multiple redundantsurfaces are evident. It allows for an increase of the maximum load fac-tor and, equivalently, a decrease of the minimum dynamic pressure in atrimmed ight, while maintaining a low wing deformation.
