P47 Curtiss 836 propeller information

[Knolly]

Hi guys, 

 

Bit of a long shot but here it goes!

 

I'm sure you have all probably seen the attached picture of a hole blown through a blade supposedly from AAA while attacking ground targets.

 

As part of my studies I want to investigate if this is true and if so how far was the blade away from failing. However, I am having great difficulties finding any technical information about Curtiss blades such as material, construction and design loads.

 

I was wondering if anyone here had any such information or could point me in the right direction? 

 

Cheers

 

Knolly

One interesting thing is that the shot would have come from rear to front given the way the propellor is blown out.

I've spent some time in the past looking for detailed information on the internet about these props and failed, so it is indeed a bit hard to come by. Generally, it might make sense to contact the Curtiss company about their archives, the Smithonian national air and space museum, for their archives, or to contact people on the internet who have in articles or forum discussions provided some insight. They may have useful sources or contacts. My own motivation wasn't high enough to do this on this subject.

 

If you come up with anything, please write an article and publish it on the internet. You've made me curious already.

Thanks for the replies guys, as this is for a project with deadlines I don't have the luxury of spending too much time digging for information. I am thinking I may need to cut my loses and pick a new subject.
