Aerodynamics

Categories: Physics | Science
    • The main application of aerodynamics is aircraft design
    • Aerodynamics can also be used for designing trains and automobiles
    • The three basic forces involved in aerodynamics are thrust, drag and liftDynamic Flight: Basics of Aerodynamics
    • Supersonic speed is a speed greater than the speed of sound, measured in Mach numbersTiscali: Supersonic Speed
    • Chuck Yeager was the first to fly at supersonic speed in 1947Chuck Yeager: Aviation History
    • Hypersonic speed is 5 times the speed of soundUS Centennial of Flight Commission: Hypersonics
  • Aerodynamics is the study of the dynamic motion of air as it meets an object. The field is related to gas dynamics and fluid dynamics.Infocell: Gas Dynamics in Areotechnology Fluid Dynamics Inc.: Definition of Fluid Dynamics Analyzing the flow of air around an object enables the accurate calculation of forces acting upon it. Calculations include pressure, temperature, velocity and density.NASA: Beginners Gide to Areodynamics This allows the development of equations for momentum, energy and conservation of mass. The use of aerodynamics permits scientific experimentation of heavier than air flight.
  • Sound Barrier

    The sound barrier is the point at which an aircraft changes from transonic to supersonic speed. The term originates from World War II when pilots began to experience a range of aerodynamic effects including compressibility. In the 1950s more planes began to break the sound barrier on a regular basis.
