Electromechanical Guidance Fin Actuation in a Four Inch Diameter Air Vehicle

Four independent guidance fin actuation subsystems have been packaged in an air vehicle section only four inches in diameter. The Control Actuation Section (CAS) of the IRTGSM submunition is seven and one half inches long. Within this envelope are the four electromechanical actuators, three thermal batteries, Flight Control Element Electronic (FCEE) module, four guidance fins (in the retracted position), and connector and structural interfaces. Location of the CAS and the air vehicle are shown in Figure 1.
