Sensor-Craft Analytical Certification

This study developed a multi-disciplinary conceptual design of a joined-wing sensor-craft. Initial analysis was conducted using an aluminum model. Linear fully stressed design and flexible aerodynamic trim were used to converge to a minimum weight design that was aerodynamically stable. This optimized design was buckling safe. A similar optimization process using non- linear fully stressed design and flexible aerodynamic trim was conducted. The non- linear structurally deformation was over ten times greater than the linear structural deformation. Again, the model was structurally and aerodynamically optimized. The linear optimization was repeated using a composite structural model incorporating Conformal Load-bearing Antenna Structures. This research demonstrated the importance of considering non- linearity and the coupling of aero dynamic and structural design.Air Force Inst of Tech Wright-Patterson AFB OH School of Engineering and Management is the author of 'Sensor-Craft Analytical Certification', published 2003 under ISBN 9781423504610 and ISBN 1423504615.
