    • Abstract

       

      How lift is generated by a moving wing is understood satisfactorily.But the rigorous explanation requires elaboratetheoretical background, and hence there are many simplerexplanations in the popular literature. In the first part of thisarticle, some such popular models are discussed after brieflydealing with some required preliminary ideas. The concludingpart of the article will deal with some simple quantitativemodels and then tie up many of these simple ideas and propositionstogether to the rigorous momentum conservation principleplacing these popular models in perspective.
