The European Commission Project COCOMAT (Improved MATerial Exploitation at Safe Design of COmposite Airframe Structures by Accurate Simulation of COllapse) is a currently running four-year project that aims to exploit the large strength reserves of composite structures through a more accurate prediction of collapse. Accordingly, one of the COCOMAT work(More)
This paper derives the governing equations of motion for a flapping wing robot that is used to study and synthesize bio-inspired closed loop control laws. Lagrange's equations are employed to derive the geometrically nonlinear equations of motion. The Denavit-Hartenberg convention is used to model the wing flapping kinematics and the aerodynamic loads are(More)
Computational fluid dynamics (CFD) modeling was used to predict the gas-solid hydrodynamics of fluidized beds. An Eulerian-Eulerian multi-fluid model and granular kinetic theory were used to simulate fluidization and to capture the complex physics associated therewith. The commercial code ANSYS FLUENT was used to study two-dimensional single solids phase(More)
Two-dimensional computational fluid dynamics (CFD) is applied to better understand the effects of wing cross-sectional morphology on flow field and force production. This study investigates the influence of wing cross-section on insect scale flapping flight performance, for the first time, using a morphologically representative model of a bee (Bombus(More)
This paper derives a history dependent formulation of the equations of motion of a flapping wing, ground-based robotic system and constructs an associated adaptive control strategy to track observed flapping motions in insect flight. A general methodology is introduced in which lift and drag forces are represented in terms of history dependent integral(More)
