Reducing Aerodynamic Drag and Fuel Consumption Improved fuel economy from other shape changes The DOE effort to reduce truck aerodynamic drag* The DOE Energy Efficiency and Renewable Energy, Office of FreedomCAR & Vehicle Technologies, supports a collaborative effort of 9 organizations: LLNL, SNL, ANL,NASA Ames, USC, Caltech, UTC, Auburn, GTRI This course extends fluid mechanic concepts from Unified Engineering to the aerodynamic performance of wings and bodies in sub/supersonic regimes. 16.100 generally has four components: subsonic potential flows, including source/vortex panel methods; viscous flows, including laminar and turbulent boundary layers; aerodynamics of airfoils and wings, including thin airfoil theory, lifting line ... 1) Problems in the aerodynamics of an ideal (non-viscous and thermally non-conducting) fluid, the word "fluid" being used in this context to denote both liquids and gases. 2) Problems in the aerodynamics of viscous fluids. 3) Problems in the aerodynamics of radiant gases. 4) Problems in the aerodynamics of rarefied gases. highways, to give a few examples. Therefore, bluff body aerodynamics has always lain at the heart of wind engineering. This paper will review a number of bluff body aerodynamic phenomena and their effect on structures and on people. One of the fascinations of wind engineering is the great variety of bluff body aerodynamic problems that are ...
NASA History Division INTRODUCTION TO THE AERODYNAMICS OF FLIGHT [NASA SP-367] Theodore A. Talay Langley Research Center Prepared at Langley Research Center Scientific and Technical Information Office National Aeronautics and Space Administration, Washington, D.C. 1975 Automotive Aerodynamics Laurent Dumas Abstract The car drag reduction problem is a major topic in the automo-tive industry because of its close link with fuel consumption reduction. Until recently, a computational approach of this problem was unattainable because of its complexity and its computational cost. A ﬁrst attempt in this direction
Why study aerodynamics? •!Anything can fly, as long as you put a big enough rocket engine under it. But: –!That s the most expensive and dangerous solution –!There are still stability, control and other problems that can only be resolved through a good aerodynamic study –!There are several much better solutions. A few of them are listed in This handbook, Aerodynamics, is one of a series on ballistic missiles. It presents design information peculiar to ballistic missile flight, i.e., information outside the scope of basic subsonic and supersonic aerodynamics which may be termed "conventional aerodynamics." Accordingly, this handbook treats the problems
AERODYNAMICS LABORATORY OBJECTIVE: The objective of this lab is to teach students, the importance of physics through involvement in experiments. This lab helps to have knowledge of the world due to constant interplay between observations and hypothesis, experiment and theory in physics. ae.sharif.edu THE AERODYNAMICS OF FRISBEE FLIGHT 3 PROBLEM STATEMENT. The purpose of this study is the view the two-dimensional trajectory of a standard Frisbee using the equations for aerodynamic forces and by reconstructing a previous model, with a few
Aerodynamics - Page 28 Aviation Seminars AERODYNAMICS AND AIRCRAFT OPERATIONS Definitions Angle of attack is the angle between the wing chord line and the direction of the relative wind. It changes as your flight path changes. Chord line is the line between the leading and the trailing edge of the airfoil.
