“…A fifth limitation is that the flight model of the BWB treated the aircraft as a rigid body; aeroelasticity was not modeled. Carlsson [35] found that the control effectiveness of a BWB decreased with an increase in airspeed due to static structural deformation.…”

The blended wing body (BWB) is a tailless aircraft with the potential to use 27% less fuel than a conventional aircraft with the same passenger capacity and range. The primary purpose of the current study was to determine the handling qualities of the BWB, using piloted-handling trials in a moving-base simulator. The secondary purpose was to determine the effect of simulator motion on handling-quality ratings. De Castro conducted piloted-handling trials in a fixed-base simulator. De Castro's tasks and flight model were modified in the current study. In the current study, three subjects rated the handling qualities as Level 1 or 2, depending on the task. Simulator motion did not have a significant effect on the results.ii Acknowledgements I would like to thank Professor Peter Grant for welcoming me into the Vehicle Simulation Group and sharing his knowledge. Professor Grant gave me a choice of several interesting thesis topics; I appreciate being able to pick the one I found most exciting. I would also like to thank Bruce Haycock, Stacey Liu, and Amir Naseri for their help with setting up the piloted-handling trials and their expertise in flight simulation. To the pilots who volunteered for the handling trials -I thank you for participating. This research was made far more meaningful because of your contribution.

“…The blended wing body aircraft is a creative airframe design which seamlessly combines a flying wing with a futuristic fuselage. It has potential advantages in lower carbon emissions, reduction of noise, higher speed, longer flight range, and broader internal volume [1,2]. However, due to the flying wing configuration, the longitudinal stability of the BWB aircraft decreases as the angle of attack increases, even at small angles of attack.…”

This paper presents results from testing the Active Aeroelastic Wing wind tunnel model in NASA Langley's Transonic Dynamics Tunnel. The wind tunnel test provided an opportunity to study aeroelastic system behavior under combined control surface deflections, testing for control surface interaction effects. Control surface interactions were observed in both static control surface actuation testing and dynamic control surface oscillation testing. The primary method of evaluating interactions was examination of the goodness of the linear superposition assumptions. Responses produced by independently actuating single control surfaces were combined and compared with those produced by simultaneously actuating and oscillating multiple control surfaces. Adjustments to the data were required to isolate the control surface influences. Using dynamic data, the task increases, as both the amplitude and phase have to be considered in the data corrections. The goodness of static linear superposition was examined and analysis of variance was used to evaluate significant factors influencing that goodness. The dynamic data showed interaction effects in both the aerodynamic measurements and the structural measurements.
