Structural analysis and properties of impact ices accreted on aircraft structures

摘要

This final contractor report presents a summary of work done on the experimental measurements of the mechanical properties of impact ices and analytical studies of ice stresses and mechanical deicing systems. Experimental work on the adhesive shear strength, the peel strength, the bending strength and tensile strength of impact ices. The major analytical studies that were completed are as follows: (1) Ice shedding by the EIDI system, (2) Impact Ice stresses in rotating airfoils, (3) Aerodynamic forces in ice shedding, (4) Interface shear stresses from bending and twisting, and (5) Statistical structural analysis of ice shedding from rotating airfoils. In this report, results and data from each experimental and analytical study are summarized. A total of twenty (20) technical papers and one MS Thesis were written and/or presented from the work done in this project.
