Impulsive Load Destructive Effects Reduction in Launch Vehicles Using Structural Joint

Abstract

Aerospace systems and subsystems are subjected to impulsive loads due to several reasons like engine start and burnout, separation, and so on. These loads may make temporary or permanent failures in some sensitive components or subsystems. To avoid these failures some constraints should be consider in design mechanical process. Another approach can be reducing the load level in transmission path without any change in the source of load and without adding any new component and only with design optimization of available components i.e, structural joints destructive effects of impulsive loads. This paper uses analytical results of joints behavior to present practical solution for minimizing load transmission through the joint
