An Investigation of Appendage Drag

Abstract

The purpose of this report is to provide information about the resistance, interaction and scaling of appendages. A calculation procedure is developed that can be used to compute the Reynolds number dependent components of appendage drag. A correlation is made between the calculated values of drag and data obtained from bare hull and appended ship-model resistance tests. This correlation indicates that the mathematical model is an effective means of predicting the viscous drag of appendages and that the added drag due to pressure as well as interaction between appendages and the hull form is of a small order of magnitude.
