Icing Analysis

Icing Analysis

To get an aircraft to pass FAA approval for flying in icing conditions it requires rigorous analysis and testing. Defense and private aircraft which may also encounter icing conditions need to be designed and analyzed in order to keep passengers safe. We use icing analysis software to guide the design and implementation of ice protection equipment.

Icing Buildup Safety Concerns

Ice buildup can significantly change the aerodynamic properties of an aircraft, cause antennas to vibrate dangerously and fail, block an engine’s intake or carburetor causing engine stoppage, and more. Ice build up on the wings, fuselage, and nose can significantly increase drag on an aircraft requiring an increase in the angle of attack to make up for the reduced lift which can cause further build up of ice. Frost, snow, and ice accumulation on wings can increase drag by up to 80% and reduce lift by over 30%. While many aircraft are outfitted with anti-icing measures, non-protected surfaces such as antennas, flag hinges, control horns, and more contribute to about 30% of the total drag associated with icing.

Understand How Icing Affects Aircraft

ASR performs icing analysis to deliver a comprehensive understanding of how icing affects the aerodynamics of your aircraft. We use TECPLOT 360 for viewing and LEWICE 3D written by Colin Bidwell of NASA Glenn for performing the icing analysis.
