Icing Environment Rotor Test Stand Liquid Water Content Measurement Procedures and Ice Shape Correlation
Abstract:An Adverse Environment Rotor Test Stand (AERTS) facility has been designed and constructed. The facility is able to reproduce natural icing conditions surrounding rotating blades with a maximum diameter of 9 ftand tip speeds of up to 470 ft/s. A Liquid Water Content (LWC) calculation methodology was developed, and procedures to determine experimental LWC in the facility are presented in this paper. Ice shape measurements on a 10.5-inch-chord, 9-ft-diameter, NACA 0012 rotor were obtained at the AERTS facility and compared with experimental results obtained at the NASA Glenn Icing Research Tunnel. The experimental ice shape correlation is excellent, with stagnation ice thickness and impingement limits deviating by less than 1% between results obtained in the AERTS facility and NASA Glenn Icing Research Tunnel. Ice shape correlation demonstrates the capability of the facility to produce accurate icing clouds.
