dc.description.abstractThe study reported herein was funded by Department of the Army Project 4A061101A91D, "In-House Laboratory Independent Research," under the sponsorship of the Assistant Secretary of the Army (R&D). The study was conducted during 1973-1974. The project was conceived by Mr. G. W. Turnage, Mobility Research and Methodology Branch (MRMB), Mobility Systems Division (MSD), Mobility and Environmental Systems Laboratory (MESL), at the U. S. Army Engineer Waterways Experiment Station (WES). Most of the data analyzed in this report were obtained from tabulations in the publi~hed literature. Also presented are some hitherto unreported data from a previous test program accomplished by personnel of MRMB and the Mobility Investigations Branch (MIB), MESL. This study was conducted under the general supervision of Messrs. W. G. Shockley, Chief of MESL, and A. A. Rula, Chief of MSD, and under the direct supervision of Mr. C. J. Nuttall, Jr., Chief of MRMB. The report was prepared by Mr. Turnage. Special acknowledgment is made to Dr. E. T. Selig and Mr. C. T. Wang, State University of New York at Buffalo, Buffalo, New York, for furnishing the author with a corrected tabulation of data from tests conducted at the NASA Langley Research Center, Landing Loads Test Track, and for their permission to use these data. BG E. D. Peixotto, CE, and COL G. H. Hilt, CE, were Directors of WES during the conduct of the study and the preparation of the report. Mr. F. R. Brown was Technical Director.en_US
