Need help on Aluminum propeller

In summary, the conversation discusses the need for an expert on propeller design and applications, specifically for a proposed aluminum propeller for powered para gliders. The individual is seeking arguments for and against the design before it reaches the blueprint stage. The proposed design calls for a 1mm thick aluminum alloy 6063-T6 "skin" with internal rib support to maintain weight and integrity. The conversation also mentions the possibility of milling or casting the propeller and references a live thread on the topic.

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.

1. What material is an aluminum propeller made of?

An aluminum propeller is made of, as the name suggests, aluminum. More specifically, it is made of an aluminum alloy, which is a combination of two or more metals to enhance its properties.

2. How does an aluminum propeller compare to other propeller materials?

Aluminum propellers are known for their lightweight and corrosion-resistant properties, making them a popular choice for boats and airplanes. They are also relatively affordable compared to other materials such as stainless steel or brass.

3. How do I choose the right size aluminum propeller for my boat?

The correct size of an aluminum propeller depends on several factors, including the boat's weight, engine power, and desired performance. It is best to consult with a professional or refer to the manufacturer's guidelines to ensure you choose the right size.

4. Can aluminum propellers be repaired if damaged?

Yes, aluminum propellers can be repaired if they are damaged. However, it is essential to have the repair done by a professional to ensure the propeller maintains its balance and performance.

5. How often should I replace my aluminum propeller?

The lifespan of an aluminum propeller depends on how often it is used and the conditions it is exposed to. Generally, it is recommended to replace an aluminum propeller every 2-3 years or if there are signs of damage or wear and tear.
