Talk:Zeppelin LZ 121 Nordstern

Engine Management

How do you start the engines? Wkitty42 (talk) 09:26, 13 August 2019 (EDT)

Last time I tried it was by setting magnetos, mixture rich and run the starter. Possibly I needed to increase the throttle quite a bit too? There are no special parts coded for. AndersG (talk) 15:13, 13 August 2019 (EDT)

i'll have to try playing with it some more... i had trouble with the Zeppelin NT but did get it started after i wrote on its talk page... i forget exactly what i had to do but it was increasing the throttle or something more than i had already increased it... that was several hours ago and i've forgotten now... the engines do seem to take some cranking over for a bit before they do start...

Yes, and looking in the files I see that I'm not sure where I got the propeller inertia (ixx) from - I don't see any propeller weight stated anywhere - so the propeller inertia may well be much heavier here than it really was. The engines also lack the tuning to give 240 hp at (up to) 1800 m (but that would have made them far stronger below 1800 m in JSBSim until some coding for failures had been added).
