Comparative Study between Schrenk and CFD Analysis for Predicting Lift Distribution along Wing Span of Glider Aircraft

Abstract: The preliminary analysis of wing of glider aircraftis presented. It gives a decisive consideration for early steps in building a plane. Lift distribution of the wingbecome important consideration to make sure that the generated lift is enough to against its aircraft weight. There are many ways of methods to predict the lift distribution. Theoretical approach is accounted from Schrenk method while more complex calculation is done by Computational Fluid Dynamic method. The objective of this work is to compare the lift distribution between Schrenk and CFD methods. The problem is formulated for high aspect ratio wing that being analyze at 0.0 degree angle of attack and Mach number of 0.07. The result indicates that there is a difference of lift distribution between Schrenk and CFD method.Hal. 108-117: ilus.; 29,5 c
