本文介绍了一种新的自适应结构，提供流量调节和控制的概念设计原则。虽然具有普遍适用性，这些设计原则，围绕使用后屈曲面板的不稳定性和弹性非线性行为的想法，举例说明通过一个案例研究：形状自适应进气口的设计。入口包括可变形的后屈曲构件，其根据周围流体施加的压力场改变形状，从而调节入口孔。通过调整后屈曲状态下的应力场和初始无应力构造的几何形状，可变形部分可以快速通过以完全关闭或打开入口。由于其固有的改变形状的能力，以响应外部刺激，即由不同的操作条件所施加的空气动力学负载，进气道不需要依赖于联动装置和机构的驱动，不像传统的流量控制装置。
This paper introduces conceptual design principles for a novel class of adaptive structures that provide both flow regulation and control. While of general applicability, these design principles, which revolve around the idea of using the instabilities and elastically nonlinear behaviour of post-buckled panels, are exemplified through a case study: the design of a shape-adaptive air inlet. The inlet comprises a deformable post-buckled member that changes shape depending on the pressure field applied by the surrounding fluid, thereby regulating the inlet aperture. By tailoring the stress field in the post-buckled state and the geometry of the initial, stress-free configuration, the deformable section can snap through to close or open the inlet completely. Owing to its inherent ability to change shape in response to external stimuli—i.e. the aerodynamic loads imposed by different operating conditions—the inlet does not have to rely on linkages and mechanisms for actuation, unlike conventional flow-controlling devices.
