Abstract : The report summarizes all work performed by Southwest Research Institute during the past 8 month period in conducting an experimental study of surface effect take-off and landing (SETOL) craft skirt flutter. The test results reported were obtained utilizing two-dimensional models representing typical trunk segment configurations. Test results obtained with these models are being used to provide baseline flutter data for a corresponding theoretical effort. In addition to providing data for the theoretical work, these model tests were directed toward discovering the types of flutter oscillations that can occur, the mechanisms that are important in predicting the occurrence and magnitude of skirt flutter and the ranges of parameters over which flutter can occur.
