Experimental analysis on bending strength and uniaxial compression strength of glaze ice

Abstract

Abstract:

Aircraft icing is a significant hazard requiring extra attention in winter, and the shed ice can cause engine damage if it impacts an engine surface with enough mass and velocity. Glaze ice is more susceptible to aerodynamic forces that result in shedding. The experimental analysis of bending strength and uniaxial compression strength for glaze ice helps to analyze the ice shedding from the blade. Thus, the ice sample is generated with spraying to simulate the ice buildup on the engine blade during icing environment encounter. A compression test instrument is designed to measure the compression strength of glaze ice. A linear function is established between temperature and compression strength based on experimental data. The current experimental study can be applied for the analysis of mechanical properties of glaze ice and help to evaluate any engine compressor damage that results from ice shedding.

Key words: glaze ice, bending strength, uniaxial compression strength, environmental test, temperature
