The pressing need for high-fidelity transient, nonlinear, viscous, fluid-structure simulations arises in the solution of many important engineering problems. These include not only the design of high-performance aircraft where flutter, limit cycle oscillation, and buffeting remain the most important considerations, but also new emerging applications such as the aeroelastic tailoring of the front a ...

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/icing boom, and egress operations associated with military systems, but ...

The reduction of aerodynamic/hydrodynamic noise caused by violent turbulence is of strategic importance to many military systems. These include modern fighter aircraft, unmanned weapons with sensitive electronics, and underwater vehicles. For all these systems, aerodynamic or hydrodynamic noise can produce unacceptable levels of operational loads or acoustic vibrations, or be detrimental to their ...

Testing and clearing hypersonic systems is a challenging task. When anything unexpected occurs, the time to react is so short that the tested article must be destroyed. Because ground-based experimental facilities such as shock tunnels and arc-jets are typically unable to reproduce the flight conditions experienced by these systems, a fast multidisciplinary computational technology is required for ...

While modern static analysis tools have progressed significantly, barriers to adoption still exist due to the turnaround time between submitting code and producing analysis results, and due to the inability to model code paths which traverse externally supplied codeblocks, such as 3rd party library functions. This submission targets these two challenges from a number of directions, with intended d ...

Cyberdynamics Incorporated is proposing research to explore and demonstrate the benefits of using scattering center (SC) models as the primary information input of HRR aircraft signature databases and aircraft identification algorithms.  Techniques of model-based scattering center extraction from complex range profiles will be studied and demonstrated.  The portability of SC model representation ...

Future spacecraft missions demand solar arrays that can provide extremely-high specific power, ultra-low stowage volume, extremely-high power capability, high reliability, and affordability.  Current state-of-the-art optimized solar arrays rely on heavy composite honeycomb structures and are approaching performance plateaus (~100W/kg and ~13kW/m3).  Deployable Space Systems (DSS), in partnership ...
