ACV Cushion Comparison Tests. Preliminary Review and Definition of Model and Tests.

摘要

The prime objective of this cushion comparison program is to be able to obtain data on the various existing cushion systems, that can be compared directly in the context of the amphibious assault mission. The use of a series of scale models, built and tested to a common standard, will provide a means of obtaining basic performance data that can be compared directly. The model is to be a dynamically similar representation of an air cushion vehicle (ACV) designed to the requirements of the Navy's amphibious assault mission. The purpose of the model is to provide data for the comparison of cushion systems. A linear scale factor of 1/12 full scale for the model was selected. The features considered most important are flexible skirt that contains the cushion, the lift fan system and the lift air distribution system together with the general hull form. The amphibious assault lift ships, that are to carry the ACV's, impose strict limits on the major dimensions of the craft. These are to be reflected in the model.
