I am using the CLARK Y airfoil but you can assume any other one you want. If everthing is "fixed" so what is the variable? Well, I want to find the optimum chord wing length for this plane which is gonna bring me the highest flight duration. The wing shape is rectangular (I know elipses would be the better shape but let's fix the wing shape to simplify this discussion). Having said that, my total plane weight (not considering the wing, of course) is around 300g (summed weight of ESC, servos, 1000kv motor, 11 inch prop, fuselage, tail, receiver and battery). IMHO to get longer flight time I need to consume the least amount of energy from my lipo battery as possible - so I need to keep my brushless motor running in the slowest RPM possible, consuming less Amps. I already built dozens of rc planes but this time I want to make this one the most efficient as possible. My question is this: I already have an rc plane (with tail, fuselage.) and I want to optimize the wing size in order to get efficiency and the longer flight time. I already went to the excelent RC GROUPS community but, despite the generous help of many people, this subject got a little more confusing and personal opinions (practical experience) are conflicting. I am having a very hard time optimizing the wing size of my rc plane.
This Aviation SE forum looks the perfect place to ask this question: people here usually make maths the root of most solutions and I think this may solve my aerodynamic optimization problem!
