Aerodynamics of Runback Ice Accretions
… performance penalties. In general, the NACA 23012 experienced greater aerodynamic performance penalties due to the runback simulations than did the NACA 3415. Low-fidelity simulations of the cold hold case agreed quite well with their medium fidelity counterparts. In the descent case, …

Flight envelope protection using flap hinge moment measurement
… Tests were conducted on two airfoil models, an NACA 3415 and an NACA 23012, at Reynolds numbers of 1.8 × 106 and 1.0 × 106. The effects of six different simulated contamination configurations on the performance characteristics of both airfoils were tested. These configurations consisted of glaze …

Performance of an airfoil with a power-saving, tab-assisted flap system
… of Illinois at Urbana-Champaign (UIUC) on a NACA 3415 airfoil model with a flap including a trim tab. Measurements were taken for two configurations: a baseline fixed tab case where tab deflection was zero and a tabbed case where multiple flap and tab angle combinations were tested. Hinge …
