How can I use 2D airfoil data for calculations in my RC helicopter project?

AI Thread Summary
The discussion centers on using 2D airfoil data for calculations in an RC helicopter project, with a focus on applying blade element theory. The original poster expresses a desire to build an RC helicopter and has studied helicopter aerodynamics, finding momentum theory easier to grasp. There is uncertainty about how to effectively utilize 2D airfoil data within the context of blade element theory. A suggestion is made to consider starting with a kit or pre-made helicopter for practical experience before attempting a custom design. Practical experience is emphasized as a valuable step in the learning process.

Hi everybody,
I am a native of Bhutan and have been always contemplating on building a RC helicopter for myself. In this regard,I have studied helicopter aerodynamics and want to swing into action.
The momentum theory seems a bit easy to comprehend and perform calculations there. But I'm unsure of how to use 2 dimensional airfoil data for performing calculations using the blade element theory.
Thanks for any help in advance.

If I were doing this, I would buy a kit or a pre-made one and play around w/ it to get practical experience before trying to design my own. Just a suggestion.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
