  • The thermal stress of wing skin produced in high temperature environment can be effectively released by corrugated structure. This paper investigated the thermal stress of two forms of corrugated skin structure, the arc shaped and the rectangular shaped. The influence of reinforce slot radius (width) and depth on thermal stress at fixed end and middle cross section was analyzed. The research shows that (1) the reinforce slot could absorb the thermal stress and reduce the stress level of the structure,(2) the structure of simple supported boundary condition had a lower thermal stress level than that of fixed boundary condition,(3) there is a critical region when the slot radius (width) and depth was among in, the thermal stress at fixed end and middle cross section decreases as the reinforce slot radius (width) and depth increase,(4) the rectangular shaped structure has a lower thermal stress level under the same radius (width) and depth.
