Conventional helicopters have two rotors. Autodesk® CFD software provides flexible fluid flow and thermal simulation tools with improved reliability and performance. How is General Aerodynamic Simulation Program abbreviated? GASP stands for General Aerodynamic Simulation Program. Automotive Aerodynamics Simulation Using a Supercomputer (http://www. SoccerNASA: Using the SoccerNASA applet, students learn about aerodynamics by controlling the conditions of a soccer kick. I spent a lot of hours in a very short timespan to do this as a quick experiment. This chapter discusses the fundamentals of aerodynamics as it relates to gliders and glider performance. Air-fields are not supported, force-fields won't take airflow into account. This course extends fluid mechanic concepts from Unified Engineering to the aerodynamic performance of wings and bodies in sub/supersonic regimes. The computer facilities, including supercomputers and peripheral equipment, represent the state of the art. This is taken into account in the "Cd" variable. For this course, we will be using SimScale, which is a browser-based software.
