“…Ref. [8] showed the feasibility of trimming the aircraft by moving an internal mass-actuator longitudinally instead of using elevator in a straight level flight condition. This study also showed that using mass-actuators instead of deflections of the control surfaces has benefits in terms of endurance and range without increasing the weight of the aircraft.…”

This paper is to follow up on prior work on a mass-actuated airplane that is controlled by internally moving masses instead of conventional control surfaces. The mass-actuated aircraft effectively has two control variables: the internal positions of two control masses, one of which is moved longitudinal along the body x-axis and the other is moved laterally along the wings. Prior works showed feasible trim results of mass actuated airplane during straight level flight and steady state turn with and without side slip angle at constant altitude. This work investigates the controllability of the aircraft with mass actuation. Furthermore, to determine quality or level of controllability by mass-actuation as compared to that by aerodynamic control surfaces, two different methods are used: (i) a measure of controllability based on controllability Gramian and (ii) values of pertaining entries in control/input matrix.
