An Aluminum Sandwich Panel Fatigue Test Under Mach-2.4 Cruising Conditions


Progress has been made in recent years in studying the effects of aerodynamic heating, which is a relatively new factor that must be accounted for in designing and testing aircraft structures. A great deal of effort has been spent to develop analytical methods that include the effects of elevated temperature. Most such methods, applicable to full-scale structures, are approximations at best and make no accounting for strength degradation due to transient conditions that vary with time. Therefore testing that must include time-dependent cyclic loads as well as static loads for maximum conditions continues to be a primary tool of the structures engineer in evaluating structures designed for sustained supersonic flight.
