Title

A detailed study on Lift Augmentation conventional techniques used in airfoil

Abstract

Purpose – Lift augmentation in aircraft wings has been a major concern since the early age of fixed wing aircrafts. Though a lot of research work has been done on this topic previously there has not been any prominent technique that has outshined all the other techniques in terms of resultant lift augmentation. Thus here is a detailed comparative study about some of the better performing lift augmentation techniques that has used flow separation using various techniques. Design/methodology/approach – This paper explores the implications of various types of techniques used for flow separation over a naca 4 series aerofoil using different methods. Findings – Lift augmentation in an airfoil is the process by which we do the flow separation over the top surface of an airfoil through the cross section. There have been several techniques used for this but the most effective flow inject techniques are use of dual vents and piezoelectric oscillating ducts for NACA4 series and other large size aircrafts but these techniques require a great deal of power thus they are not that cost effective in case of small aircrafts. Practical implications – This paper will help the manufacturers a detailed view with all the different techniques used for flow separation over an airfoil for lift augmentation and will take through the different aspects of their working. This will also show the advantages and disadvantages of all the flow separation techniques. Before the selection of the flow separation techniques one should look into the following aspects :1)Selection of suitable sample airfoil and study of flow separation.2)Comparative study of existing and flow injections design3) Practical implementation of flow injection technique in sample designs.
