Icing tests were conducted to document ice shapes formed on three different two-dimensional airfoils and to study the effects of the accreted ice on aerodynamic performance. The models tested were representative of airfoil designs in current use for each of the commercial transport, business jet, and general aviation categories of aircraft. The models were subjected to a range of icing conditions in an icing wind tunnel. The conditions were selected primarily from the Federal Aviation Administration's Federal Aviation Regulations 25 Appendix C atmospheric icing conditions. A few large droplet icing conditions were included. To verify the aerodynamic performance measurements, molds were made of selected ice shapes formed in the icing tunnel. Castings of the ice were made from the molds and placed on a model in a dry, low-turbulence wind tunnel where precision aerodynamic performance measurements were made. Documentation of all the ice shapes and the aerodynamic performance measurements made during the icing tunnel tests is included in this report. Results from the dry, low-turbulence wind tunnel tests are also presented.

**A week-by-week, step-by-step instructional guide.** This timely book offers a clear and structured method for integrating explicit phonics instruction into K–3 classrooms. An essential guide for teaching reading, the book is grounded in the cutting-edge, evidence-based science of reading. It provides a flexible and effective step-by-step progression that covers the essential phonics skills that teachers have been asking for, and addresses the needs of busy, diverse classrooms. This blueprint to effective instruction explores screening, assessment, and intervention, as well as working with English language learners. Tools for implementation include high-impact activities, lesson templates, word lists, phoneme-grapheme grids, word ladders, and more.
