Scientific Computer Software
Scientific Computer Software projects at AOI include both government standard codes and Small Business Innovative Research (SBIR) commercial codes. The SBIR codes include physical models and computation methods which span multiple technical disciplines to provide complete target/background signature characteristics for dynamic engagement simulations.

Three ongoing SBIR Phase II projects funded by the Missile Defense Agency are designed to provide high-speed/high-fidelity unified simulations of missile body/plume optical signatures. These projects include
- Target End-to-End Signature Simulation (TESS) for body dynamics/heating/signature
- Flow Advanced Simulation Tool (FAST) for nozzle/plume and/or body/wake flow
- Radiation Advanced Simulation Tool (RAST) for plume/atmosphere emission/scattering
