Male and Female Male and Female InterfacesInterfaces
-Acme Stub Threads with a pitch of 6
-Half inch interference zones for placement in warhead/motor
-All dimensions made to match current rocket interfaces precisely
-Threaded push pins used to secure interfaces to module shell (not shown)

Canard and actuation mechanism shown
- actuation gear attaches to assembly here
ACTUATION MECHANISM COMPONENTS
Springs for deployment and locking mechanism to prevent canard from closing once deployed
Internal Frame
-Machined from solid piece of aluminum
-Allows for placement of IMU, GPS, and CPU

Internal Frame
CANARD MOUNTING LOCATION
Mounting bar offset 45 deg from frame to accommodate canard assembly and servomotors
Placement of Servomotors
-Mounts for servomotors currently being designed
-Servos mounted at angle to line up proper angle with actuation gear
FRAME WITH ELECTRONICS
-Thermal battery and insulation (red) attach to end of frame
