ABSTRACT:
Methods and apparatus for deploying control surfaces generally comprise a fin deployment system for projectiles. The fin deployment system is used to control the timing of the control surface deployment. In one embodiment, the deployment system comprises a clip that is configured to react the biasing force of one control surface against another in order to maintain the control surfaces in a non-deployed state until at least one control surface is able to overcome the retention force of the clip, thus beginning a chain reaction in which all of the control surfaces deploy sequentially.
