    Bristol Jupiter engines

    I'm engaged in drawing the Westland Wapiti / Wallace aircraft family. Can anyone help please with the following.

    I need scans of the following engine information, so if any forum member has a side view dimensioned drawing for the Jupiter VI, such as might be found in the AP or engine manual, also the same for the Pegasus IIM or Pegasus IV. I have the dimensions I need for the Jupiter VIII the from drawing in the Jagan book "The Westland Wapiti in the Indian Air Force. The most needed dimension in each case is that from the engine mounting plate to the tip of the propeller shaft.

    I have some dimensions from the American built Bliss Jupiter's and if these mirror the Bristol ones (as I suspect they will) then I need to find a troublesome 2.5" difference in the overall lengths of the Wapiti II and IIA.

    Cheers

    John

    One dog walk later and a brilliant result on my return. Thank you so much TerryP. This will help narrow down the grey areas.

    Again thank you.

    Cheers

    Nice copies of the drawings. You wouldn’t have the description box with the ‘drawn by’ etc., would you?

    No, the Jupiter drawing is from the AP dated 1930, and the Pegasus from a Bristol handbook. Neither have any real title block with drawn by etc.

    No hassle but did you have a personal email from me? I've sent a couple through the forum recently and had no reply to either and one was an answer to a friend.

    Regards

    John
