Abstract
Cruise missiles are guided missiles that usually have the configuration of a small aircraft propelled by a turbojet engine. Many of these missiles have sophisticated guidance systems and are designed to fly at low altitude following the terrain elevations in order to hinder detection by radar and thus adopt a path with many changes of direction and altitude. The maneuvers performed by an aircraft subject all its embedded components to intense dynamic loading. The objective of this work is to estimate the effect of the maneuvers performed on a typical cruise missile trajectory on the rotor dynamic behavior of a low power turbojet engine. To carry out this study, an implementation of the finite element method for the analysis of flexible rotors and hard disks was developed in a routine written with a numerical computing software.
