Investigation of an Improved Finite Element Model for a Repaired T-38 Horizontal Stabilizer Flutter Analysis Using NASTRAN.

Abstract

This thesis investigated the use of an improved finite element model of a T-38 horizontal stabilizer for flutter analysis using NASTRAN. The procedure for evaluating the effect of repairs on the flutter speed is developed and its sensitivity to several modeling assumptions and practices is presented. The procedure is to be used by Air Force engineers to evaluate repair limits of T-38 stabs. The results show that the current repair limits have little or no effects on the flutter conditions, therefore, the procedures presented in this investigation should be used to establish new repair limitations.
