Dynamically Scaled Research Testbed

Project goal: To design and construct three sets of 35-degree swept wings with varying flexibility that are compatible with the X-56A MUTT fuselage. Although wings with high aspect ratios increase aerodynamic efficiency, the resulting large wingspans amplify the magnitudes of torsional and bending moments. The Dynamic Scaled Research Testbed is a one-third dynamically scaled fuselage modeled after the Lockheed Martin X-56A MUTT used to test these dynamic interactions. Analytical methods are used to determine the required geometric and material properties of three different sets of spars, which dictate the stiffness of the corresponding wing. These analytical methods are then verified using numerical finite element analysis and ground testing. Sensors and additional avionics were designed and installed to record telemetry and flow conditions over the wing during flight-testing. Following extensive structural and electronic ground testing, flight tests were performed to validate the design and gather data for research. The upgraded testbed will allow researchers to gather flight data and contribute to the safe and effective use of flexible wings with high aspect ratios.
