Magnetic Technology in Propulsion Systems
Propulsion Systems in Guided Munition
Guided munitions rely on precise navigation and propulsion for mission success. Dexter’s high-performance magnets optimize propulsion, delivering unmatched power efficiency while enabling pinpoint accuracy in even the most demanding conditions. As modern propulsion systems evolve, magnets have become essential in not only generating thrust but also in steering and controlling missiles through complex, high-speed maneuvers.
The main source of propulsion in many guided munitions is a rocket engine, which provides the thrust to accelerate the missile. In solid or liquid-fueled rockets, fuel combustion produces hot gases that expand and eject at high speed, creating forward motion. However, traditional rocket propulsion is only one part of a highly sophisticated guidance and control systems.
Dexter Magnetic Technologies supports the core components of these systems.
Thrust Vector Actuation (TVA): TVA systems manipulate the direction of the thrust produced by the engine. This is critical for maneuvering the missile during flight. Particularly for maintaining or altering trajectory to hit fast-moving or distant targets. TVA systems use actuators to change the orientation of the engine’s nozzle, adjusting the angle of thrust to steer the missile. With permanent magnet motors integrated into TVA systems, these actuators become more efficient and reliable, allowing for faster response times and more precise control. This is essential for missiles operating in high-speed or rapidly changing environments.
Thrust Vector Control (TVC): While TVA focuses on controlling the direction of the engine’s thrust, TVC goes a step further by managing the overall attitude and angular velocity of the missile. Magnets play a crucial role in TVC. They provide high-torque motors that offer the power and responsiveness necessary for fine adjustments during flight. These high-performance magnet motors are compact yet powerful. Which ensures the missile can make rapid corrections without adding significant weight or bulk to the system.
Propulsion systems rely heavily on sensor technology to guide and stabilize the missile. Magnets, paired with Hall Effect sensors, help track the position of various components within the missile. These sensors provide real-time data that the propulsion system uses to adjust for altitude, speed, and direction. The ability to detect small changes in the missile’s position or trajectory allows for much more accurate mid-flight adjustments, improving the chance of a direct hit on a moving target.
