Abstract
Quiet supersonic flight over land appears increasingly viable, based on significant advancements in aircraft shape optimization. One of the next critical milestones will involve community scale surveys, measuring the public response to events that sound as benign as distant thunder. The present paper describes a measurement infrastructure to reduce the field costs associated with those tests. Specifically, a scalable grid of NI CompactRIO data acquisition systems has been developed and deployed in a risk reduction test. Highlights of the system include communications via a wireless rf network and synchronization using low cost GPS receivers. This paper highlights some of the development challenges, solutions, and recent results from component and system level risk reduction testing at the NASA Dryden Flight Research Center.
