Abstract

The Avionics Wind Tunnel SBIR is a project sponsored by the Air Force Research Laboratory at Wright Patterson with Amherst Systems Inc. The goal was to perform a closed-loop test, stimulating an operational avionics component, capturing its reaction, and injecting it back into the threat simulation. The project integrated several existing and new technologies to evaluate cost-effective methods for performing avionics system evaluation. Distributed Interactive Simulation technology was used to interface the system under test (SUT), the ownship platform and the threat environment simulation. The threat environment was provided by two sets of models. One set was designed to serve as a campaign level simulation and provided background signals. The second set of models was considered `medium' fidelity and provided the primary input to the SUT. The data from the two sets of models and data from the ownship was blended and fed into the stimulation equipment that provided RF signals for the SUT. The reaction of the SUT to the stimulation was digitally monitored on a MIL-STD-1553B bus and fed back to the threat models that modified their action.
