Systems Deployment&Relative Motion Analysis

ABSTRACT: Today, a pressing need for high-fidelity transient, nonlinear, viscous, multidisciplinary simulations of complex fluid-structure systems with associated subsystems operating in near space arises in the design and analysis of many engineering operations. These include not only the cargo/weapon release, store separation, fueling/de-icing boom, and egress operations associated with military systems, but also those associated with commercial applications such as the optimization of draft during car racing and the design of biomedical micro devices for drug delivery, among many others. To address this pressing technical need, Phase I of this SBIR effort has focused on blending the arbitrary Lagrangian Eulerian and overset/chimera methods to design a new framework for the fluid-structure analysis of complex systems with flexible structures and large relative motions. During Phase I of this effort, the feasibility of this new concept was also demonstrated. Hence, Phase II of this research project will focus on refining this innovative computational technology, implementing it in the AERO Suite of Codes deployed at the Edwards Air Force Base, and maturing its application to the nonlinear aeroelastic analysis of complex systems and subsystems with large relative motions. BENEFIT: The anticipated success of this research and development effort will extend the range of applications of arbitrary Lagrangian Eulerian and overset/chimera methods to systems deployment and large motion analysis that accounts for both structural flexibility and turbulent viscous flow effects. It will also enhance the potential for commercialization of the AERO Suite of Codes deployed at the Edwards Air Force Base by expanding its range of applications to include problems such as cargo/weapon release, store separation, aerial refueling, optimization of draft in Indy and Formula 1 car racing, and the simulation of biomedical micro devices for drug delivery.
