Welcome to the Beginner's Guide to Aerodynamics | ||||
What is aerodynamics? The word comes from two Greek words: aerios, concerning the air, and dynamis, which means force. Aerodynamics is the study of forces and the resulting motion of objects through the air. Judging from the story of Daedalus and Icarus, humans have been interested in aerodynamics and flying for thousands of years, although flying in a heavier-than-air machine has been possible only in the last hundred years. Aerodynamics affects the motion of a large airliner, a model rocket, a beach ball thrown near the shore, or a kite flying high overhead. The curveball thrown by big league baseball pitchers gets its curve from aerodynamics. | ||||
At this Web site you can study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance; the three forces (lift, drag, and weight) that act on a glider; and finally, the four forces that act on a powered airplane. Because aerodynamics involves both the motion of the object and the reaction of the air, there are several pages devoted to basic gas properties and how those properties change through the atmosphere. There is a special section of the Beginner's Guide which deals with compressible, or high speed, aerodynamics. This section is intended for undergraduates who are studying shock waves or isentropic flows and contains several calculators and simulators for that flow regime. . There are many pages here connected to one another through hyperlinks and you can then navigate through the links based on your own interest and inquiry. There is an Aerodynamics Index of topics that you |
How Did We Learn to Fly Like the Birds? Myths and Legends of Flight Greek Legend - Pegasus Bellerophon the Valiant, son of the King of Corinth, captured Pegasus, a winged horse. Pegasus took him to a battle with the triple headed monster, Chimera. Icarus and Daedalus - An Ancient Greek Legend Daedalus was an engineer who was imprisoned by King Minos. With his son, Icarus, he made wings of wax and feathers. Daedalus flew successfully from Crete to Naples, but Icarus, tired to fly too high and flew too near to the sun. The wings of wax melted and Icarus fell to his death in the ocean. King Kaj Kaoos of Persia King Kaj Kaoos attached eagles to his throne and flew around his kingdom. Alexander the Great Alexander the Great harnessed four mythical wings animals, called Griffins, to a basket and flew around his realm.
