Aerodynamics can be defined as the way air moves around the things. The principles of aerodynamics explains how an aeroplane is able to fly in the atmosphere. There are four forces that acts on flight and they are: lift, weight, thrust and drag. The force of aerodynamics comes from gravity pulling the objects down.This force makes the objects or things move up and down. So aerodynamics plays an important role in aerospace engineering. The open access journals are peer reviewed scholarly journals of aerodynamics. The top open access journals are freely available on the public internet domain, allowing any end users to read, download, copy, distribute, prink, search or link to the full texts of the articles. These provide high quality, meticulously reviewed and rapid publication, to cater the insistent need of scientific community. These journals are indexed with all their citations noted. The top open access journals are indexed in SCOPUS, COPERNICUS, CAS, EBSCO and ISI.
