In this paper, we exploit structural instabilities and elastically nonlinear behaviour as an engineering tool for designing an adaptive air inlet for fluid flow control. The device includes a shape changing post-buckled composite plate, which regulates the inlet aperture of a connected duct by snapping in response to changes in the pressure field of a surrounding fluid. The post-buckling stresses of the composite plate induce the intrinsic capabilities required for multi-stable snap-through, while the post-buckled shape creates the aerodynamic pressure fields for actuation. These concepts are validated here by means of Fluid-Structure Interaction (FSI) simulations and wind tunnel experiments.
