An Automated Procedure for Flutter and Strength Analysis and Optimization of Aerospace Vehicles. Volume 1. Theory and Application

Abstract

This volume documents the theoretical developments that are incorporated into a computer program entitled FASTOP (Flutter And Strength Optimization Program). The program is capable of both integrated analysis and efficient (near-minimum weight) sizing of cantilever or free-free lifting surface structures in the presence of strength and flutter-speed constraints. Automated resizing of a finite-element structures model in FASTOP leads to an efficient final design in which three categories of elements exist, viz.:-- elements at manufacturing constraints, strength-critical elements (these elements are fully stressed for at least one load condition), and flutter- critical elements (these elements, which were resized for flutter without encountering manufacturing or strength constraints, have uniform flutter- velocity derivatives). The specific analysis and redesign capabilities of FASTOP are summarized.
