[edit] Pegasus XC thrust?=

While researching for this article I came across several different thrust values given for the Pegasus XC e.g.

920 hp / 686 kW (German Wiki, WW2 aircraft site etc)

919 hp (www.pprune.org/forum/archive ...)

910 hp / 680 kW (Century of Flight site)

900 hp (Century of Flight site)

660 hp / 492 kW (Imperial Airways site)

In the end I chose the last value because it came from the Imperial Airways site and I decided that the operator would know (and because it seemed unlikely that there would be such a leap in engine power from the 595 hp of the Jupiter XFBM to 920 hp; 660 hp seemed more feasible!); but one extremely detailed and accurate site ([1] Brian Cassidy's "Flying Empires") gives 920 hp / 686 kW and I am minded to use these values after all!

What look like a competent source ([2] www.oldengine.org) gives

HP(max)=790 hp and

HP(take off)=910 hp, which differs only slightly from Cassidy's figure.

Can anyone help sort this one out? Many thanks! TraceyR 18:38, 25 January 2007 (UTC)

I've got another source for the 660 hp for the Pegasus XC in the Scylla - i.e ">*Donald, David (Editor) (1997). The Encyclopedia of World Aircraft. Aerospace Publishing. ISBN 1-85605-375-X.  and this seems anout right for 1936 - but much higher values seem to be quoted for installations in other aircraft - i.e. ~900 hp - could it be aircraft specific?
