摘要

Atmospheric and space environments is a field covering a broad spectrum of disciplines, and this year's accomplishments reflect that variety. NASA has added a new tool for ice accretion studies. New system applications were demonstrated for space weather, which remains an area of intense interest. NASA Glenn has adapted a commercial 3D laser scanning system to capture and quantify the 3D features of ice accretion on aircraft. The surface data can be used to validate 3D ice accretion code and to generate computational fluid dynamics grids for computational aerodynamic analysis. The data can also be used to manufacture artificial ice shapes for aerodynamic testing using rapid prototyping or 3D printing. An extensive validation and verification study was performed to ensure the system was capable of capturing all the relevant features of the ice accretion, including roughness.
