Naval Surface Warfare Center, Crane is establishing a modular and flexible, system-level HWIL for avionics analysis. Prototype solutions are being sought for a system-level HWIL infrastructure to support the verification of system and mission performance, and to provide a platform to test and integrate advanced capabilities under various environmental and threat stimuli in real-time.

Evaluating systems using a HWIL/Software-in-the-Loop (SWIL) methodology is not a new concept, however, its application in support of emerging technology areas required by this project has not yet been developed. Most notably, this technology does not exist in a manner that supports seamless usage across multiple avionics platforms. To achieve economy of scale in supporting multiple avionics systems, a flexible and adaptable HWIL/SWIL infrastructure is required.

Using this method of simulated testing facilitates early identification of technology issues and opportunities, thus reducing risks prior to “live” operational testing. The system-level HWIL must also support assessment of not just emerging technology performance, but overall weapon system and mission performance through simulation of real-world environments (e.g. operational and threat environments) in real-time.

The HWIL Other Transaction Authority (OTA) prototype project will be executed over a 60-month period.
