Aerodynamic Analysis of a Wing and Propeller by Panel Method Sayyed Morteza Naghavi Alhosseyni mortezanaghavi@me iut ac ir February 11 2009 Department of Mechanic Isfahan University of Technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSuper Advisor Dr Ahmad Sedaghat sedaghat@cc iut ac irSuper Advisor Dr Ahmad Reza Pishevar apishe@cc iut ac irAbstract In this research we want to investigate interaction of propeller on wing We do this work in potentialenvironment to use its equations and reduce solution costs In this way we model the three dimensional wingby distribution of source and doublet We suppose effects of propeller and its revolution as an input velocityprofile for wing We can find this distribution from different theories But for having steady state answersand so to model swirl velocity of behind propeller we use the momentum theory that is one of the actuatordisk models At first we test the wing with off motor propeller that shows code results have very good agreement withexperiment We can find such these results in total lift coefficient and total drag coefficient versus angle ofattack diagrams and local lift coefficient versus span of wing After turning on the motor propeller swirl and axial velocities due it as input velocity to wing add to fluidvelocity at infinity and finally appear in equations as zero flow normal to the surface boundary condition Total lift coefficient versus angle of attack that is acquired from this state have a good agreement withexperiment and local lift coefficient follows experimental diagrams Key Words Panel Method Propeller Wing Actuator Disk Interaction
