Wow thanks for the feedback. I am impressed by how thorough you guys read this rather geeky and narrow article. May I ask what made you interested in reading this?
It is always interesting for me to understand my readers a bit better.
Anyway to answer your question. The 233 500 kg lifting capacity was the theoretical lifting capacity I calculated based on the measurements I could obtain about the Hindenburg Airship online.
However the officially given lifting capacity is 232 000 kg. So my theoretical / calculated lifting capacity is about 1000 kg too high.
216,204 kg calculated gross lift is about 1000kg higher than the official given gross lift of 215,910. So this is very close to what we could expect.
That these numbers don't align 100% is to be expected since my calculation is a simplification. E.g. the Hindenburg is unlikely to be a perfectly shaped prolate spheroid.
Part of the storage and passenger area is inside the speroid will would reduce area available for hydrogen gas. My calculations don't include this reduction. And the it isn't just one large envelope with hydrogen gas. The envelope contains multiple smaller ballonets with hydrogen. Some of them contain blaugas used for fuel.
So it makes sense that my estimate is above the actual value.
