Abstract
This paper presents a novel methodology for continuous parameterisation of movables, which takes advantage of the ability of the doublet lattice method to describe aerodynamic forces using downwash. The movables are described in the continuous space using a downwash distribution generated using a B-spline surface. The parameterisation allows for any number of control surfaces to be positioned along the trailing edge of the wing. A high aspect ratio strut-braced wing aircraft model has been used to determine the handling qualities and manoeuvre load alleviation performance at different flight conditions, demonstrating and assessing the methodology for modelling movables distributions. The results in the paper demonstrated a successful application of a novel continuous movable parameterisation methodology, which can be applied to an aircraft for which only the planform and initial structural parameters are known. Furthermore, the results obtained with the continuous parameterisation advocate for the use of movables which can change their shape in the spanwise direction.
