Abstract

Right from lift-off launch vehicles are subjected to extreme dynamic pressure aero and structure borne excitations. Inter-stage is fundamental to the vehicle as it houses the different control equipments actuators sensors motors and avionic packages. This paper involves the creation of two different models so as to study the correlation using two approaches Finite Element method and Hybrid Method involving Statistical Energy Analysis and Finite Element Analysis. The correlation of the response obtained on the Inter-stage from an acoustic ground test to that from the analytical test results carried out with VA One is also addressed in this paper.
