Skyraider propeller blades

[quang]

Hello guys,

 

I took these photos of a former VNAF Skyraider on display in Saigon. 

Incidentally the propeller blades on this plane are mounted backwards (back to front). 
Should they be mounted properly, I wouldn't have noticed this curious detail: a small angled 'ledge' running lengthwise on the trailing edge of the blade. 

Now that I know it's there, I can see it on several other Skyraider photos although it's hard to notice since the 'ledge' is located on the back of the propeller. 

Can you A-1 experts shed some light on this curious detail? 

 

Thank you

Quang

I don't know what it is but I do know that the pitch on the prop in your pictures is all hosed up. That is the leading edge.  The prop turns counter clockwise when facing it.

Exactly Ron. The blades are mounted backwards

Well it will make a good leaf blower then!

Oh shoot, those commies had it all back wards..... :wicked:

I am currently building the Trumpeter kit. I did some correction to the Trumpy propeller blades which are too narrow but I don't think I can reproduce the 'ledge'. Ah well...

The prop leading edges are cambered to provide extra "lift" forwards. Zoukei Moura got this detail correct, not Trumpeter, hence the AMS correction set!

 

The SA-16B had the same camber on the wing leading edges.

Thanks you Stein for your input.

Unfortunately the AMS blades are OOP

I have an extra set! 😀

Well well if it's just sitting there gathering dust and you don't mind getting rid of it, send me a PM

Not out OOP, just OOS (out of stock) I am casting them this coming week.

Harold, you're my man!
