    P-51D propeller technical data request

    The prop file for JavaProp that unix_nerd posted gave me a good starting point and I was able to figure out how to use JavaProp to generate a full set of table data. I now have generated a set of prop tables. Initial testing with the new prop data went well and things felt right with...

    P-51D propeller technical data request

    Some sources also list 0.42. This makes sense since the V-1650 series was derived from the Merlin 61 which is listed as having a 0.42 ratio. I believe that 0.42 is correct for the V-1650-7 since a lower ratio would result in lower prop tip speeds and for faster the aircraft this will allow for...

    P-51D propeller technical data request

    I had a look at this and it appears that your input file is in error. The merlin was geared and the prop RPM at an engine RPM of 3000 was 1260 RPM. But even with that I don't know how to use JavaProp to generate what I need. Perhaps you can give some clues of how to go about using it to...

    P-51D propeller technical data request

    The hub is the 24D50 but it was fitted with different blades. The main thing I need is the two tables that have the thrust and power coefficient data. These tables will look something like this: Thrust coefficient table advance blade angle ratio 15 25...

    Warbird automixture

    The injector units on the on the Packard Merlins were from Bendix. And tommayor is correct about icing. It was possible for there to be induction system icing with these injection systems but it tended to happen in places like the air duct leading to the injection unit or at the mouth of...

    Warbird automixture

    Old post but the OP didn't really get his question answered. In the Packard Merlin powered P-51 aircraft there were two different "injector carburetors" used. The use of the term carburetor is misleading since these were really machanical throttle body fuel injection systems and were fully...
