Abstract
A fluid flow control device includes a resilient substrate translatable between a first flattened position and a second extended position, and an actuator attached to the resilient substrate. The actuator is configured for translating the resilient substrate from the first flattened position to the second extended position. The actuator is formed from a shape memory alloy transitionable between a first state and a second state in response to a change in temperature of the shape memory alloy. A fluid flow control system includes a rotor shield and the fluid flow control device attached to the rotor shield.
