Happy Hartzell

Engineering is soo cool – whilst most would find this kinda boring and yeah, its just a bit on a plane, Sarah Joy made a great point that many people do not realise the amount of development work and effort that goes into the hundreds of assemblies and parts that make up a plane. Here is one such bit, one of the simplest constant speed propellers/hub you will see on small 2 or 4 seater aircraft.


I get to see lots of plane bits, but not that often a full propeller hub, in bits 🙂 this one was a unserviceable and had all the bits from the last overhaul. So whaddya do with a Hartzell Propeller which you have in bits, a pair of verniers and a few spare hours? you model it of course and turn it into a animated mechanism. 🙂
well the spare hours is a bit of a lie, I really don’t have those, but did spend a couple of late nights on it 🙂
