The Role of Magnetics in Aerospace Fixed Wing Motors

Flight Control Actuation Systems 

Precision and reliability are non-negotiable when it comes to flight control actuation systems in aerospace engineering. Ailerons, elevators, and rudders are controlled by these systems, which heavily rely on advanced motor technologies. Central to these systems are high-performance magnets, a critical component that Dexter Magnetic Technologies excels in designing and delivering. 

Flight Control Elements:  

  • Ailerons: On the outer edges of the wings, ailerons are hinged surfaces whose primary function is to control roll, which is rotation around the aircraft’s longitudinal axis (nose-to-tail). In order for the aircraft to turn, pilots need to tilt the wings in opposite directions—one up and one down.  
  • Elevators: Elevators control pitch, or the up-and-down movement of its nose, on the horizontal stabilizer of the tail. Lifting the nose causes the aircraft to climb. Dropping the nose causes the aircraft to descend. Taking off, landing, and maintaining level flight all require pitch control.  
  • Rudders: A rudder controls yaw, the side-to-side movement of the aircraft’s nose, located on the vertical stabilizer. During turns, rudders keep the aircraft stable and prevent unwanted yaw, but they can also make coordinated turns. By moving the rudder left or right, the aircraft’s nose swings in corresponding directions.

A fixed-wing aircraft motor must be designed to survive harsh conditions, including vibration, temperature, and extreme weather conditions. At Dexter Magnetic Technologies, rare-earth magnets such as NdFeB and SmCo are used. These materials provide the necessary strength and resilience required to operate under these demanding environments, ensuring flight stability and responsive control. 

 

Flight control actuations systems are critical to an aircraft’s stability and maneuverability. The motors driving these systems rely on advanced magnetic technologies to maintain their performance in even the harshest environments. At Dexter Magnetic Technologies, we provide custom magnetic solutions designed to meet the demanding requirements of aerospace applications, ensuring your aircraft operates with precision, efficiency, and reliability.
