Need help on Aluminum propeller

AI Thread Summary
The discussion focuses on designing a 1.2-meter diameter aluminum propeller weighing approximately 1000 grams for powered paragliders. The creator seeks expert advice on propeller design and applications, specifically looking for pros and cons before finalizing the blueprint. Concerns are raised about achieving the desired weight with a thin blade, and the design includes a 1mm thick aluminum alloy 6063-T6 skin with internal rib support for structural integrity. There is mention of casting as a potential production method. The thread concludes with a request to redirect further discussion to a live thread link provided.

I need to contact who ever would be authority on propeller design and applications.

In short, the Idea is to build a Aluminum prop, 1.2 meters diameter with weight of about 1000 grams. Targeted application would be primarily for powered para gliders. I need some arguments for and against before it leaves blueprint stage.

If you can point me in the right direction as to who the best contact for me would be, I would be ever so grateful.

If any of you have experience on the issue, comments are more than welcome.

I'm afraid that I can't help you with that. It does seem to me, however, that you'll have to have an awfully thin blade to keep the weight that low with metal.

Design calls for 1mm thick Al aloy 6063-T6 "skin" with internal rib support in order to achieve desired weight yet maintain the integrity needed for the application.
 
Ahhhh...
I thought that you were talking about milling or casting one. Still can't help you, but it makes more sense now.

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...
