Abstract

Variable camber/span/chord scheme for morphing flexible skin requires the skin to have the capacity of in-plane large deformation in one dimension and the ability to provide adequate out-of-plane bending and compressive rigidity. A zero Poisson's ratio mixed cruciform honeycomb is proposed and used as flexible skin design by covering silicone panel on its surface. The in-plane deformation mechanism of the honeycomb is theoretically analyzed, as well as the effect of the cell shape parameters on mechanical properties. Targeting the in-plane one-dimensional morphing capacity, the parameters of the honeycomb are optimized. The honeycomb structure is equivalent to an orthotropic material, and the resistance to bending out-of-plane and its influencing factors of the mixed cruciform honeycomb are studied. According to the design requirements of the variable camber trailing edge wing flexible skin, the applicability of the mixed cruciform honeycomb's structure parameter is studied. The results show that the designed honeycombs not only meet the operational requirement of the flexible skin but also have a light quality and small driving force.
