Howdy everyone,
I've finally gotten around to looking at the Privateers Vehicle Manual Creation Rules and I'm having trouble with the Jet drive, page 102. I tried to recreate an early model Airbus A320 with an operating weight of about 38 metric tons and an air speed of 650 km/h using two CFM56-5 turbofan engines. My web search indicates that the engine have a dry weight between 1.95 and 3.9 metric tons depending on the series.
Plugging an A320 with a weight of 38 tons with an air speed of 650 km/h built at TL 25 my engine mass works out to be about 73.3 tons. Thinking that I might have a problem using paper, pencil, and calculator, I whipped up an Excel spreadsheet. Unfortunately I'm still getting the engine as massing about 73.3 tons.
My luck with searching for topics relating to my issue of the jet drive has been down right pathetic. Can some kind soul please help me out here. Also are there tutorials for designing various vehicles?
Respectfully,
