Advanced Composite Materials in Typical Aerospace Applications
Composites are becoming increasingly important in the aerospace industry. At least 30-40 per cent of modern airframes are now made of composites, and this percentage is increasing rapidly due to technological advances in the field. The use of composites for primary structures such as fuselages and wings has grown significantly in transport aircraft. Apart from increased strength at lower weights, composites also meet fatigue and damage tolerance, gust alleviation, and low noise foot print requirements. This paper examines the challenges and advantages of using composites in airframe manufacture, as opposed to other alloys. It also looks at the ways and means to ensure that safety and durability are not compromised by the use of composites. The prime objective of this paper is to highlight the use of advanced composite materials in the field of aerospace and to encourage readers to understand and to write papers on such topics.
Aerodynamic Characteristics of a Real 3D Flow around a Finite Wing
This paper presents a new method of solution for the aerodynamics of finite-span wings, which overcomes the difficulties of the previous methods. A lot of disturbance is created in the air when an aeroplane flies. It is through the study of these disturbances of the flow past the airfoil, lots of design considerations are done. In this paper, we design a 3D air wing and solve the flow equations in a CFD solver and study the characteristics features of the flow around a finite wing and the effect of the tip vortices that are caused by the difference of pressures between the lower and upper portion around the tips on an air airfoil.
