Actuation system for torpedo control surfaces

摘要

An interior actuation system for controlling an exterior control surface of a torpedo or the like which has an afterbody with radial inlet vanes defining inlet liquid passages to the propellers of the torpedo. A linear actuator is mounted in the afterbody. A bell crank is connected at one end to the linear actuator and extends radially outwardly therefrom through one of the inlet vanes. A driving connection, including a link arm connected at one end to the opposite end of the bell crank, extends longitudinally from the bell crank through the afterbody outside the liquid passages and operatively interconnects the control surface to the linear actuator.
