Abstract : The design and utilization of military aircraft in forward area situations has required a continual investigation of those factors which define the aircraft flotation performance and operations capability on semi- and unprepared soil runways. This report documents an analytical technique developed to predict the sinkage resulting from tire/wheel braking on a soil surface. A detailed description of the approach used is provided. Preparation of the computer program is explained including the instructions for input data. The results of several example cases are provided. Appendices are included for the governing equations, lumped parameter model developed and the Fortran IV source listings produced. (Author)
