=== Fins ===

We currently estimate the fins to be 4“ x 4” squares constructed out of fiberglass. As we develop a more realistic model for our system for our control law, we will be able to more accurately determine how large of an area our fins will need to cover to exert the necessary torque to resist rotation.

We currently estimate the fins to be 4” x 4” x 3/32” squares constructed out of fiberglass. As we develop a more realistic model for our system for our control law after we receive orientation data from a test flight, we will be able to more accurately determine how large of an area our fins will need to cover to exert the necessary torque to resist rotation. The fins will be connected on a worm gear mechanism, in order to prevent movement on accent, consequently protecting the fins from any kind of unintentional actuation.

For our stability fins on our aft airframe, we will be using off-the-shelf fins from Giant Leap Rocketry with the root chord of 8.5“, tip chord of 4”, and height of 8.5".

For our stability fins on our aft airframe, we will be using off-the-shelf fins with the root chord of 8.5”, tip chord of 4”, and height of 8.5”, and a Coefficient of drag of 0.14.
