The model was tested at transonic cruise flight conditions with Reynolds numbers based on mean aerodynamic chord ranging from 10 to 30 million. The goal of the test was to experimentally validate a new design method, referred to as Crossflow Attenuated NLF (CATNLF), which shapes airfoils to have pressure distributions that delay transition on wings with high sweep and Reynolds numbers. Additionally, the test aimed to characterize the NTF laminar flow testing capabilities, as well as establish best practices for laminar flow wind tunnel testing. Preliminary results regarding the first goal of validating the new design method are presented in this paper. Experimental data analyzed in this assessment include surface pressure data and transition images. The surface pressure data acquired during the test agree well with computational fluid dynamics (CFD) results. Transition images at a variety of Reynolds numbers and angles of attack are presented and compared to computational transition predictions. The experimental data are used to assess transition due to a turbulent attachment line, as well as crossflow and Tollmien-Schlichting modal instabilities. Preliminary results suggest the CATNLF design method is successful at delaying transition on wings with high sweep. Initial analysis of the transition front images showed transition Reynolds numbers that exceed historic experimental values at similar sweep angles.","PeriodicalId":93407,"journal":{"name":"AIAA Atmospheric Flight Mechanics Conference 2019 : papers presented at the AIAA SciTech Forum and Exposition 2019, San Diego, California, USA, 7-11 January 2019.

For loading in the y-direction, curved inclined walls exhibited in a higher modulus, with the largest increases at the highest cell angles examined (60 deg). Conversely, for loading in the x-direction, curved inclined walls exhibit a lower modulus with the greatest decreases at the lowest cell angles examined (15 deg). The predicted differences in stiffness between cells with straight and curved inclined walls is experimentally demonstrated. The increase in y-modulus as well as the reduction in x-modulus with the curved inclined walls is attributed to the lower wall slope at the wall junctions. The peak vonMises stress at the junctions is generally lower for curved wall cells than for straight wall cells. The reduction exceeds 25% for loading both in the x-direction and y-direction.","PeriodicalId":93407,"journal":{"name":"AIAA Atmospheric Flight Mechanics Conference 2019 : papers presented at the AIAA SciTech Forum and Exposition 2019, San Diego, California, USA, 7-11 January 2019.
