Abstract

The design of a cruise missile wing is a multidisciplinary work, since the wing has to provide enough aerodynamic forces while being structurally safe. In order to meet the design requirements and achieve a successful design, several parameters of the wing need to be investigated at various flight conditions. In this paper, lift forces and flutter speeds are obtained for different wing geometries, at various altitudes and speeds. The design of experiments is constructed by changing the several variables of the wing to have better understanding of the effect of design parameters. The aerodynamic analyses for predicting the lift force are performed by using FLUENT and the aeroelastic analyses for the determination of the flutter speed are conducted by using ZAERO package programs.

Highlights

The wing may be considered as the most important component of a cruise missile, because it is needed to reach long range
The purpose of this study is to indicate the effects of changing various design parameters on the performance of a cruise missile wing at different flight conditions
The lift forces and flutter speeds are obtained for different geometries in the design of experiments (DOE)

Summary

Introduction

The wing may be considered as the most important component of a cruise missile, because it is needed to reach long range. The primary function of the wing is to generate the sufficient lift force and its design involves fundamental trade-offs between aerodynamic and structural aspects. The wing needs to produce sufficient lift force while being away from flutter problem. In order to reach an optimum wing geometry, providing aerodynamic and aeroelastic design goals, predicting the effects of design parameters is very important. As the wing design problem includes additional design parameters, aerodynamic and structural considerations can have complex interactions. In this complexity, predicting the effects of these design parameters and defining the design parameters to be optimized is highly important. The lower and upper limits for each design parameters should be correctly determined
