Chuck Harris wrote: According to a website on PT boats that I found by Google, the PT 7X series boats used a Packard V12 that was a direct descendant of the Lancaster Airplane engine. They made a point Liberty, not Lancaster. No such engine as a Lancaster, so far as I know, and the Lancaster aeroplane was powered by Merlins (most marks) or Bristol Hercules. One Motor Torpedo Boat (the solitary F-type Fairmile) got four Hercules instead of the usual Packards, bus tthe power drain of the cooling fans just about absorbed the power increase. It might have been different if she'd got Centaurus, as planned. of saying that it wasn't a Merlin, or a Packard-Merlin. Looks like there were tanks, boats and airplanes that shared a related V12 engine. Certainly most British cruiser tanks (and the Valentine and Churchill infantry tanks) had Liberty-derived V12s. Can't remember whether the shift to the Meteor was with the Cromwell or the Comet (Cromwell, I think - the related Centaur certain;y had a Nuffield Liberty) -- Andy Breen ~ Interplanetary Scintillation Research Group http://users.aber.ac.uk/azb/ "Time has stopped, says the Black Lion clock and eternity has begun" (Dylan Thomas) |

The Gloster Meteor aeroplane was pwered variously by Rolls-Royce Welland or Derwent, Halford H1 (De Havilland Goblin) or Metrovick M2 turbojets or - in one case - Rolls-Royce Trent turboprops. -- Andy Breen ~ Interplanetary Scintillation Research Group http://users.aber.ac.uk/azb/ "Time has stopped, says the Black Lion clock and eternity has begun" (Dylan Thomas) |
