The U.S. Navy’s nuclear submarine force is the country’s first and last line of defense in its global strategy of deterrence. Sentech, the global leader in the design and manufacture of position sensors, is deeply invested in U.S. Navy submarine systems support, producing Linear Variable Displacement Transducers (LVDTs), Rotary Variable Differential Transducers (RVDTs), FASTAR sensors, HYDRASTAR sensors, signal conditioners, and solenoids.
The following is a glossary of terms for submarine systems and a few of the roles Sentech sensors play in keeping the systems operating.
This is located in the aft of the submarine and powered by steam turbines, the submarine’s rotating propeller drives it through the water. In modern nuclear-powered submarines, the nuclear reactor provides the heat that produces the steam for the turbine drive.
Breathable oxygen, potable freshwater, and fuel systems are what keep the crew healthy, the steam turbines unclogged, and the submarine moving:
Each of the foregoing submarine systems involves temperature, pressure, and flow monitoring LVDT sensors manufactured by Sentech. Each are designed to work in demanding saltwater, high pressure, and high-temperature environments.
LVDT applications in submarines include measuring the position of the rods. These provide power generation to heat the water that generates the steam and drives the turbines and propeller shaft.
Submarine missile guidance systems depend on the global positioning system, gyro navigation, and velocity measurement technology. The systems use controlled ignition of rocket fuel and an automated system of feedback on what must occur and when.
LVDTs and RVDTs play an important role in guidance and precision from the violent combustion of the missile launch to keeping satellites oriented in the freezing vacuum of space.
Defense satellites are the network of solar-powered earth orbiters that guide a submarine-launched nuclear missile to its target.
Robotic controls are either automated or manually operated systems that make it possible to control robots. Underwater robots, for example, are programmed for deep dives into dangerous and remote parts of the ocean.
For example, the Navy’s Orca robot submarine, Echo Voyager, uses depth sensors and gyrometric navigation and relies on GPS navigation. It uses a diesel-electric system and a 1,000-gallon fuel supply.
