Description: Technical Report
Summary: The practical aspects of establishing and maintaining airfields on sea and fresh-water ice for normal and emergency operations are discussed. The principles of the bearing capacity of ice, and the effects of static and moving loads are reviewed. Practical recommendations are given for the choice of location, exploratory field survey, and the preparation of the airstrip. Formulas are developed for estimating ice thickness in a given region at a given time, taking into account accumulated degree-days below freezing, snow-cover depth, stream flow, and other local conditions. Estimates of the required ice thicknesses for safe and emergency landings of selected aircraft, with and without skis, are tabulated, as well as the radius of influence of loads, critical load velocities, and the thermal insulating effects of different types of snow and ice covers.
