Roll control of a MALE UAV using the adaptive torsion wing

This paper assesses the feasibility of the Adaptive Torsion Wing (ATW) concept to replace conventional control surfaces and enhance the manoeuvrability of a UAV. The ATW concept is a thin-walled closed section two-spar wingbox whose torsional stiffness can be adjusted through the chord-wise position of the front and rear spar webs. The reduction in torsional stiffness allows external aerodynamic loads to induce aeroelastic twist that can be used as a function of the flight conditions to obtain a desired roll control authority. Modelling of the concept was performed using a low fidelity quasi-static aeroelastic suite developed in MATLAB. The variation of structural figures of merit are evaluated and discussed. Finally, an MDO study was performed to have in-depth assessments of the potential benefits of the ATW in replacing ailerons and providing sufficient roll control.

Abstract

This paper assesses the feasibility of the Adaptive Torsion Wing (ATW) concept to replace conventional control surfaces and enhance the manoeuvrability of a UAV. The ATW concept is a thin-walled closed section two-spar wingbox whose torsional stiffness can be adjusted through the chord-wise position of the front and rear spar webs. The reduction in torsional stiffness allows external aerodynamic loads to induce aeroelastic twist that can be used as a function of the flight conditions to obtain a desired roll control authority. Modelling of the concept was performed using a low fidelity quasi-static aeroelastic suite developed in MATLAB. The variation of structural figures of merit are evaluated and discussed. Finally, an MDO study was performed to have in-depth assessments of the potential benefits of the ATW in replacing ailerons and providing sufficient roll control.
