Abstract
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.
Claims17
An interior actuation system for controlling an exterior control surface of a torpedo or the like which has a longitudinal axis, and an afterbody with radial inlet vanes defining inlet liquid passages to the propellers of the torpedo in the afterbody, comprising:
- linear actuation means in the afterbody and movable in the longitudinal direction;
- crank means connected at one end to the linear actuation means and extending radially outwardly therefrom through at least one of said inlet vanes;
- link means connected at one end to the opposite end of the crank means and extending longitudinally therefrom through the afterbody outside the liquid passages;
- and
- drive means on the opposite end of the link means and coupled to the exterior control surface for actuating the control surface.
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, comprising
- actuation means in the afterbody;
- crank means connected at one end to the actuation means and extending radially outwardly therefrom through at least one of said inlet vanes;
- and
- means operatively connecting the opposite end of the crank means to the exterior control surface.
An interior actuating 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, comprising:
- actuation means in the afterbody;
- crank means connected at one end to the actuation means and extending radially outwardly therefrom through at least one of said inlet vanes, the crank means being very thin in cross-dimensions relative to its dimensions in the direction of flow through said passages;
- and
- means operatively connecting the oppossite end of the crank means to the exterior control surface.
