Electromechanical Missile Control Actuation Systems

With over 25 years of experience, Parker has a strong pedigree in missile applications. Our control actuation systems are uniquely packaged to meet the demands of performing in challenging operational and storage environments. The CAS is capable of providing independent control of each surface, or utilizing mechanical linkages to provide a single channel of control to multiple surfaces.
Our missile control actuation systems (CAS) include control electronics which provide electrical power and closed loop feedback control to the DC motors, converting electrical energy to rotary motion. The control electronics receive aerosurface position commands from the missile’s guidance section through either an analog or digital communication interface. Rotary- or linear-output motion may be accommodated through a series of mechanical gear reduction stages connecting the DC motor and the aerosurface.
Motor commutation and position loop closure is achieved through sensor feedback. Sensors may include traditional bi-polar Hall Effects, rotary encoders, or resolvers depending upon the application. We can provide a wide variety of solutions, ranging in diameters from 3.5" to 14" as well as custom solutions. By combining the building blocks of mechanical advantage and electronic controls into an integrated system, we are able to deliver customized system solutions to reduce cost, lead time, and technical risk.
