An investigation was made of structures for a Ground Effect Machine GEM which would be useful in the Armys amphibious regime of transportation. Emphasis is on arriving at a structural concept which would produce a vehicle with maximized transportability. A vehicle for the Logistics-Over-The-Shore LOTS mission is selected so as to have a concrete example for design purposes. As a prerequisite to vehicle engineering, the mission, the use sequence, and the chracteristics which would make the vehicle useful and transportable are examined in detail. The most severe loads to be resisted are believed to be those associated with operating in the military amphibious environment. The miscellaneous environmental requirements are enumerated. Material properties appropriate to this kind of application are studied and a selection made -- Al alloy 6061-T6 -- primarily on the basis of its corrosion resistant property. Power requirements are determined as a function of gross weight, cushion pressure, and operating height.
