INTRODUCTION TO AERONAUTICS: A DESIGN PERSPECTIVE CHAPTER 3: AERODYNAMICS AND AIRFOILS “Isn’t it astonishing that all these secrets have been preserved for so many years just so that we could discover them!!” Orville Wright 3.1 DESIGN MOTIVATION The Physics of Aerodynamic Forces Figure 3.1 shows a cross section view of an aircraft wing. A wing cross section like this is called an airfoil. Lines drawn above and below the airfoil indicate how the air flows around it. The

Homework Introduction to Aerodynamics Name: Natalie Hume 1. In your opinion what has been the most important development/invention in the history of aerodynamics and why? I feel that I could pick something very complex and technical for this question. But I think in terms of science and simplicity I pick Bernoulli’s principle. This principle laid the foundation for the development of aerodynamics. It allowed for people to understand the relationship between pressure and velocity and continue

Aerodynamics General aerodynamics Paper aircraft are a class of model plane‚ and so do not experience aerodynamic forces differently from other types of flying model. However‚ their construction material produces a number of dissimilar effects on flight performance in comparison with aircraft built from different materials. In general‚ there are four aerodynamic forces that act on the paper aircraft while it is in flight: • Thrust‚ which keeps the plane moving forward; • Aerodynamic lift

1 Aerodynamics 2 MEC 3706/MEC 3220 Assignment 1 Due Date: 14-1-2010 (11:30 am) Q1. Plot the pressure distribution over the symmetrical double wedge‚ 8 per cent thick supersonic aerofoil shown in figure below when the Mach number meets the upper surface (a) tangentially (b) 12º and (c) .9º. Compare the lift‚ drag and pitching moment coefficients for these incidents. Assume ε0=6º Q2 A thin wing can be modeled as a 2m wide flat plate set at an angle of 5º to the upstream flow. If the wing

Aerodynamics of a Baseball John Eggler Embry-Riddle Aeronautical University Aerodynamics ASCI 309 Bryan E. Spears July 10‚ 2011 Abstract Aerodynamics is known as the study of the different forces acting on an object and the resulting motion of objects as they fly through the air. Today we know that aerodynamics plays a major role in many sports‚ such as tennis‚ soccer‚ hunting‚ and motor sports‚ we will investigate the effects

Aerodynamics Aerodynamics is a branch of fluid dynamics concerned with the study of gas flows. The solution of an aerodynamic problem normally involves calculating for various properties of the flow‚ such as velocity‚ pressure‚ density‚ and temperature‚ as a function of space and time. Understanding the flow pattern makes it possible to calculate or approximate the forces and moments acting on bodies in the flow. This mathematical analysis and empirical approximation form the scientific basis

M IMPACT OF AERODYNAMICS ON AUTOMOBILES INTRODUCTION Aerodynamic forces are caused by the relative motion of automobiles with air and they cause:  Drag (resistance to forward motion)  Lift / down force (come into play during cornering and acceleration)  Lateral forces (comes into play during cornering)  Moments in roll‚ pitch and yaw As a result these factors have to be taken into consideration during automobile design. THEORY BEHIND AERODYNAMIC FORCES The sources of aerodynamic forces are 

When you hear the word aerodynamics‚ the first thing that comes to mind is airplanes and pilots. There are other applications that apply. For instance‚ the passing of a football. A football that is thrown into the air has inertia. This is the tendency of an object in motion to remain in motion. But because of gravity the ball is pulled down and resistance that slows the ball down. A quarterback through the motions of his and body‚ must balance the forward momentum that he gives the ball‚ fighting
