Talk:Pratt & Whitney R-985

From Wikipedia, the free encyclopedia

Gentlemen:

We have been trying to find out how Pratt & Whitney developed the power charts for their round engines. More specifically how they developed the altitude correction charts for them? If anyone has any information about this, or a suggestion where I could look for this material. I would like to thank you in advance for your help.

Thanks very much.

I would contact someone at Pratt & Whitney. They are usually pretty helpful with historical research projects. - Emt147 Burninate! 02:54, 16 January 2007 (UTC)
