Complete Avionics Module Avionics Module ADDITION TO HYDRA 70 ROCKET
Male and Female Interfaces -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 Assembly
Canard Assembly Cont… Canard and actuation mechanism shown - actuation gear attaches to assembly here
CANARD Machined from a single piece of material for simplicity and added strength
ACTUATION MECHANISM COMPONENTS Springs for deployment and locking mechanism to prevent canard from closing once deployed
Yellow piece here is attachment point to frame
CANARD IN CLOSED POSITION
Internal Frame -Machined from solid piece of aluminum -Allows for placement of IMU, GPS, and CPU -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 Canard Assembly
Placement of Servomotors -Mounts for servomotors currently being designed -Servos mounted at angle to line up proper angle with actuation gear
Packaging inside module shell
