Disclosed is a throttle including: an upstream and downstream flanges; a flexible sheath that extends therebetween; a plurality of sets of shape memory alloy wires, extending between the flanges, that are (i) circumferentially aligned about the flanges; and (ii) exterior to the flexible sheath; and (iii) configured to contact an outer boundary of the flexible sheath, wherein: a first set of the plurality of sets of shape memory alloy wires form a first profile when exposed to a first temperature, causing the flexible sheath to form the first profile having a first internal diameter; and a second set of the plurality of sets of shape memory alloy wires form a second profile when exposed to a second temperature that is lower than the first temperature, causing the flexible sheath to form the second profile having a second internal diameter that is smaller than the first internal diameter.
