A Study of Requirements,Model Configurations,and Test Plans for Air Cushion System Comparison Tests.

摘要

The Navy plans to test several models of air cushion vehicles with different cushion systems. A set of model design requirements suitable for all the models was developed by the Navy with the assistance of Bell Aerospace Textron and other contractors. The proposed DTNSRDC Model Test Program was reviewed. Minor changes and additions were suggested. A preliminary model configuration using Bell cushion philosophy was proposed. Ranges of bag and cushion pressures and airflows were established for the model. Two existing model fans from an existing model of the AALC JEFF(B) could provide the required nominal flow and pressure. Bell recommends installing four of these existing fans to permit testing over a wide range of flows. Cost and schedule estimates for the model detail design and construction were prepared. The schedule is shown in this report; cost estimates were provided under separate cover. (Author)
