Aircraft propeller blade

[Ollie2525]

Hi I have a propeller blade I believe is off a De havilland Mosquito but Im not sure. The serial number is 48302. Can anyway help me to confirm this or to determine what aircraft its from? Thanks.

The drawing number will get you as close as possible to what it would have been installed on. The serial number doesn't help, unless you had the prop logbooks.

It seems that there is the DWG number at the top of the root. It looks like DWG NO. 89308-8 or 2

The blade root gear is typicaclly Curtiss prop, the blade may be DWG 89303 - 2...
fitted on Curtiss hub of
P51A, P 40C & C, E...,N

I agree. the last digit may be the "3" instead of the "8". So the DWG number can be 89303 - 2

Yes its hard to read, whats the DWG number refer to? How can I determine what aircraft this blade was fitted to?

So it could be from a Curtiss kittyhawk not mosquito is that right?

Ok thanks. How do I look up drawing numbers?

Ollie: From the base part of the drawing number, you can then identify the make and model prop. Form the model number, you can then identify the engines and then the aircraft that used that prop. Also, knowing the blade length will help you narrow your search.

As Waroff mentioned, it looks to be a Curtis blade.

Just wonder if there is something more after the digit 2 in the DWG 89303-2 ...? It could be "4W" or "7W". It would indicate the Curtiss Electric blade almost for sure .

From what is read it could be -24W for P51A and P40, at 11 feet in diameter, or -27W for A36 at 10 foot 9 inch in diameter.

 

[Wurger]

Yes that's correct.

at the root we can see the blade clamp hinge which maintain the two halves of split sleeve...it's a Curtiss duralumin blade, not for Mosquito prop

two last digit are missing, so I wrote "89303-2." followed by dots

It looks like the base and the numbers could show much better with careful clean and examination. Great answers!
