Cortana has had extensive experience reviewing preliminary submarine designs to determine potential vulnerabilities with regard to detectability and physical survivability. We have acted as an extension of the customer's team and provided the technical depth necessary to ensure a state-of-the-art design and attention to a wide range of acoustic and non-acoustic signatures. The adjacent schematic shows various flow-control devices that Cortana has the capability to model and evaluate in terms of their potential to reduce or eliminate specific submarine signatures. |

Cortana has successfully completed multi-year technical analyses for U.S. and international customers. Topics within these programs included boundary layer control techniques; detectability of submerged and surfaced submarines in the visual, near-IR, mid-IR, microwave, and radar regions of the electromagnetic spectrum; characterization of hydrodynamic signatures generated by candidate submarine designs (Bernoulli humps, wakes, thermoclines, etc.); and recommendations for specific operational procedures to enhance system effectiveness and avoid potential vulnerabilities. |

Cortana has developed a series of computer simulations that depict and predict a number of phenomona associated with submarine observables. Shown here is a simulation of a submarine mast at six knots with the attendant Bernoulli hump and Kelvin wake. Simulations such as this allow the submarine constuctor to optimize the design, and the submarine operator to plan his tactics accordingly. |
