Deployable flow control device

A deployable flow control device for a flow surface over which fluid having a fluid boundary layer flows and which said fluid boundary layer exhibits certain dynamics, comprising:

• a. a pressure source;
• b. a sealable, flexible element having two elastic states, defined as quiescent and deformed, connected to said pressure source such that when pressure from said pressure source is applied to said sealable, flexible element said sealable, flexible element changes to said deformed state;
• c. biasing means which urges said sealable, flexible element to said quiescent state when pressure is removed from said sealable, flexible element;
• and
• d. a flow effector operably connected to said sealable flexible element such that said flow effector can be deployed into and retracted out of said fluid boundary layer flowing over said flow surface based upon said elastic state of said sealable, flexible element whereby said flow effector controls said fluid boundary layer dynamics.

A deployable flow control device for use with a flow surface over which fluid having a fluid boundary layer flows which said fluid boundary layer exhibits certain dynamics, comprising:

• a. a housing attachable to said flow surface;
• b. a flow effector movably attached to said housing;
• and
• c. deploying and retracting means operably connected to said flow effector such that said deploying and retracting means deploys and retracts said flow effector, from said housing, into and out of said fluid boundary layer flowing over said flow surface whereby said flow effector controls said fluid boundary layer dynamics.
