Physics of lifting bodies is studied in some depth using the NASA Foilsim software freely available on website.With this software we can investigate how an aircraft wing produces lift by changing the values of different factors that affect lift.There are several different versions of FoilSim II which require different levels of experience with the package, knowledge of aerodynamics, and computer technology. An offline version can be downloaded and being interactive a variety of problems can be analyzed using it. In the present work a detailed analysis of ‘Physics of flow about lifting bodies' is studied. FoilSim is a computer simulator program that calculates the total "lift" of a specified wing. By using this program, the user can prove that the lifting capacity of the wing can remain the same at different airspeeds-as long as the angle of attack is changed to compensate. If the airspeed remains unchanged, an increase in the angle of attack will initially increase the lifting capacity of the wing. |
