Investigation of the Stability and Control Characteristics of Several Configurations of the DARPA Suboff Model (DTRC Model 5470) from Captive-Model Experiments

Abstract

A program of straightline captive-model experiments was performed in the vertical and horizontal planes of motion at deep submergence was performed in the vertical and horizontal planes of motion at deep submergence to determine the stability and control characteristics of the DARPA SUBOFF model. The experiments were performed for the following configurations: (1) the model fully appended in the vertical plane of motion, (2) fully appended in the horizontal plane, (3) unappended hull, (4) hull plus sail, (5) hull plus control surfaces, (6) and hull plus ring wing (Number 1). The results of the experiments indicate that the model is unstable in all of the conditions investigated.
