Abstract: Leading edge extensions are small extension to an aircraft wing which is forward of the leading edge. The main aim of adding these extensions is to improve the airflow over the wings at higher angles of attack and lower air speeds. The effect on lift produced by a dogtooth leading edge extension on a straight wing is studied and is compared with the straight wing of the same configuration. It was found out that there are considerable increments in the performance of straight wing when the same was provided with Dogtooth leading edge extension. The coefficient of lift and stalling angle was improved and it matching the performance done by NACA 2412.
