What is it about?
The goal of this study is to obtain the pressure distribution on the fin and to obtain stress distribution of this fin exposed the aerodynamic loads varying with the angle of attack. Then, these distributions is used for parametric study of stacking sequence of a laminated composite missile fin with double wedge cross-section.

Why is it important?
Aeroelasticity which can be defined as fluid structure interaction is one of the most important design criteria for the missile fins. During the flight, fins/wings are exposed to very high stresses due to the aerodynamic loads varying with the velocity profile. These stresses may cause some undesirable conditions such as fatigue and fracture of the structure. In this work, high strength laminated composite materials were used in order not to encounter such problems and structural performance of double wedge type fin was investigated at different aerodynamic loads obtained from CFD Analyses.
Perspectives
The motivation of this study is to investigate different stacking sequences of control surfaces consisting of carbon/epoxy composite layers in order to minimize the maximum deflection and increase the carried load capacity.
