PPT-Aerodynamics

Dane Johannessen Overview Aerodynamics What are the forces How do these forces affect flight What factors affect these forces What is Aerodynamics The study of forces acting on an object in motion as it passes through air. Primarily the design is driven by the aerodynamic requirements but economics mean that the blade shape is a compromise to keep the cost of con struction reasonable In particular the blade tends to be thicker than the aerodynamic optimum close to the Meyer and John L Bohn JILA NIST and Department of Physics University of Colorado Boulder Colorado 80309 Received 26 November 2007 accepted 16 June 2008 We investigate whether storing baseballs in a controlled humidity environment signi64257cantly af y, aerodynamic and aeroacoustic factors that the simple models showing voiced fricatives are W.H.

Aerodynamics is a highly refined science that vies for position with other key vehicle design considerations such as styling and ergonomics. It's importance with respect to the operating efficiencies of a vehicle is undisputed but manufacturers must steer a balanced path between the push an pull of the many other aspects of a car necessary to sell it to the consumer..
