In Phase I we demonstrated the feasibility of a novel aeroservoelastic design approach for scaled model design, and demonstrated fabrication of the resulting designs as a ground test article.nbsp; The test article from Phase I successfully replicated the scaled structural dynamic behavior, and demonstrated the integration of an instrumentation backbone based on PCB technology which allows integration of numerous sensors such as accelerometers, unsteady pressure sensors, and fiber optic strain sensors, along with the associated data acquisition, logging, and telemetry hardware.nbsp; This allows novel sensing and control approaches such as trim shape control, induced drag tailoring, flutter suppression, and load alleviation to be accomplished.nbsp; In Phase II we will demonstrate this technology in a subscale flight demonstration, raising the TRL of the technology to 8 or perhaps 9.nbsp; This work will advance the state of the art by creating technology for rapid aeroelastic scaling of new designs to model level, rapid manufacturing of aeroelastic models (both wind tunnel and scaled flying models), and richer instrumentation and sensing that would lead to more insight and more useful information for the flight vehicle designer or flight test engineer regarding the aeroelastic characteristics of the new configurations in development.
