PERFORMANCE ANALYSIS OF A SPACE SHUTTLE EXTERNAL TANK ATTACH RING USING PROBABILISTIC PRINCIPLES

摘要

This work deals with performance analysis of an external tank attach ring of a space shuttle. The shuttle consists of the orbiter and the main engines along with the solid rocket boosters, external tank (ET), and external tank attachment (ETA) ring. The study discussed in this paper is restricted solely to the ETA. Performance analysis in the traditional deterministic sense involves calculation of margin of safety values for yield and ultimate allowable stresses.
