US Lang Prop Identity

[Bob Gardner]

Dave,

I have received a request for help to identify the aircraft that an American Lang propeller was fitted to. I have no data on USA LP's. Can you help?

L.245
right hand DIA. 2.500
pitch 1.450
90hp curtiss
DR.NO.902

With regards,

Bob

I heard from him too. I'm trying to find the numbers and have requested pictures if possible.

I was a little surprised to see the diameter and pitch in metric numbers.

If L245 is the serial number, this would be an early Lang Prop?

Probably, but I don't know.

Here are some pics of the Lang propeller:

I haven't seen that particular design on a Jenny. I couldn't find the drawing number anywhere, although I did find one digit away, LP 903, which was used on Curtiss F boats and MF boats with a 100 HP OXX engine. Those were pushers, though, so this one wouldn't have worked as a pusher with that engine.

Thanks Dave. Have you passed this info to the owner of the prop?

With regards,

Dave & Bob,

Thanks for your help. The propeller is on loan to Embry-Riddle Aeronautical University in Daytona Beach, FL. I am trying to assist with the history. Any help you give will be greatly appreciated.

If I can be of any assistance to you please let me know, we have a large staff of mature and experienced aviators and aviation experts.

Jeff does the University have any information on WW1 German props? It seems unlikely! I am currently writing my volume III on them. I need;

data on individual props for my database; Dia, Pitch, engine etc
photographs of German props with identifiable decals
details of makers.

I have quite a lot of similar data, but there are gaps.

With regards,

Bob

Bob,

I will find out if we have any information and get back with you soon.
