In this paper we will be discussing about the airflow tunnels and the results of experiments conducted in an open airflow tunnel on the aerofoils. These tests were carried at low speed keeping artefact stationary and allowing the air to pass through it, the air will be blown on the experimental profile with the help of an efficient fan. The aerofoils were designed in a computer drawing tool named solidworks. Distinct aerofoils were selected for experimentation and the results were recorded and studied at various angle of attack and speed. The airflow tunnel tests of one from the selected aerofoils at various angles of attack and at a constant speed is outlined in this paper. The pressure distribution over the profile of the aerofoil surface was obtained; lift force and related lift coefficients were calculated. The conclusions derived from the scrutinization of the results will be used in the future to carry out further research and development.
