Publisher Summary This chapter explores the aerodynamic modeling. The most difficult task for the flight dynamicist is the identification and quantification of the aerodynamic description of the aeroplane. Aerodynamic modelling is concerned with the development of mathematical models to describe the aerodynamic forces and moments acting on the ...

Computational Compressible Aerodynamics
2020Analysis of aerodynamic properties of aerospace vehicles has now matured to a stage, where high accuracy computing can, to a large extent, replace the design data book’s sectional properties. In this chapter, we focus on main issues which make computational aerodynamics a practical tool.

Aerodynamics … the branch of dynamics that treats of the motion of air and other gaseous fluids and of the forces acting on bodies in motion relative to such fluids. Webster's Third New International Dictionary As you read these words, around the world there are thousands of airplanes in flight through the earth's atmosphere.

We have explored the early days of flight and some of the major aspects of aviation. We have also examined properties of fluids and the behavior of fluids at rest and in motion – the field of fluid mechanics. The atmosphere, the medium in which airplanes fly, has also been discussed.

Publisher Summary Aerodynamic noise is a phenomenon associated with high speed operation. This means that when the construction of new high speed lines is proposed, it often leads to opposition on the grounds of noise, even more than for conventional lines. As speed increases, noise inevitably also increases.

A general introduction presents the main concepts about biker and bicycle aerodynamics. A decription of the drag reduction problem is presented and the athlete position effects as well as the main bicycle components effects are examinated. Advices are proposed to improve performances (taking the international regulations as a constant reference).

Aerodynamics and Aircraft Control
1996The object of this chapter is to provide the reader with an introduction to aerodynamics. aircraft stability and control and the dynamic response and behaviour of an aircraft so as to be able to understand the role and tasks of automatic flight control systems.

Publisher Summary The design of the primary components of both axial and centrifugal compressors is relatively simple. Any complexities arise in trying to get everything to work together with a high degree of efficiency—mechanically as well as aerodynamically.
