    • A low-heat- transfer coupling or assembly is configured to mechanically couple together a pair of mating parts (12, 14), one of which may be in a heat-producing environment. By roughening at least part of the surface (36, 46) of one of the parts (12), the contact area between the mating parts can be reduced, while still maintaining the structural integrity of the connection. The roughening can be a knurling process of all or part of the mating surface on one of the parts. This can produce a series of recesses on the surface that are in contact with the other part. The recesses can be small enough, interspersed with non- etched areas of the contact surface, that structural integrity of the coupling between the parts is still maintained. The coupling may be between a leading edge of an aircraft control surface, such as a missile fin (200), and a body of the control surface.
    • 低传热联接器或组件被配置为将一对配合部件(12,14)机械地联接在一起,其中一个配合部件可以处于发热环境中。 通过使部件(12)中的一个的表面(36,46)的至少一部分粗糙化,可以减小配合部件之间的接触面积,同时仍然保持连接的结构完整性。 粗糙化可以是其中一个部件上的全部或部分配合表面的滚花过程。 这可以在表面上产生与另一部分接触的一系列凹部。 凹槽可以足够小,散布在接触表面的非蚀刻区域,部件之间的耦合的结构完整性仍然保持。 联接器可以在诸如导弹翅片(200)的飞行器控制表面的前缘与控制表面的主体之间。
