2. Experimental research on the Leading Edge Extension
aerodynamics (Master’s Research Project)
 Designed a research study on flexible and rigid, slender Delta wing and Leading Edge
Extension aerodynamics to improve the aerodynamic properties of a NACA 0012 rectangular
wing.
 Designed a flexible, slender half Delta wing type Leading Edge Extension (LEX) which was
then attached to the end of a NACA 0012 rectangular wing and then tested for its various
aerodynamic characteristics in a Low Speed Wind Tunnel using a force balance.
 Lift enhancement of 27% was achieved by the new combination of flexible LEX and
rectangular wing as compared to rectangular wing alone.
