Abstract
One of the key factors for the effective operation of a towfish is achieving quasi-static dynamic equilibrium. Therefore, the purpose of this paper is to identify the angles of attack that promote the horizontal balance of the towfish, as well as the depth at which it is established and, to develop a communication system that allows the operator to instantly monitor the depth of operation of the vehicle during missions to confirm that data is being collected by the sensors in the designated area for study. To achieve this goal, two quasi-static hydrodynamic models are developed, one for the towfish and the other for the tow cable and, in the sequence, the modeling of the cable is coupled to the modeling of the rigid body of the vehicle to enable the identification of the angles of the hydrodynamic profiles capable of maintaining the equilibrium condition at a specific depth. Finally, an algorithm is implemented to confirm that equilibrium is achieved. This research has significant relevance in the context of ocean sciences, contributing to the advancement of underwater research, the collection of reliable data and technological development to ensure efficient decision-making to manage, preserve and regulate the use of ocean resources.
