As it sounds like you have some knowledge about these engines, from the article:
“These [combustion] gases spin the [turbine] disk, which is attached by a drive arm to its associated drive shaft. The shaft then transfers the turbine’s rotational energy forward to the corresponding compressor at the front of the engine.”
I'm probably misunderstanding, but it sounds like the disk is attached to the shaft by a single so-called “drive arm”, which could be imagined to span maybe 10° on the circumference. I would have thought there'd be at least 3 such arms at 120° intervals, if not a continuous full 360° connection, which then I wouldn't call an arm. Could you clarify this point?
