[edit]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)
Displacement
[edit]Math says the true displacement is 986.75 cuin (16.17 Li). The 985 figure is a rounded number typical of the military designation system. AMCKen (talk) 04:40, 2 May 2012 (UTC)
Beech 18
[edit]This seems unlikely if the Wasp Junior was only produced until 1953: "Production of the Beech 18 with the Wasp Junior engine continued until 1970." Kendall-K1 (talk) 21:47, 16 February 2016 (UTC)
- The company website has 1953 http://www.pw.utc.com/R985_Wasp_Jr_Engine, perhaps Beech bought a job lot and continued to fit them. MilborneOne (talk) 15:49, 17 February 2016 (UTC)
