I've just stumbled over this picture. Does anybody know what kind of
engine this is?

Looking at that picture it seems to me that it would much easier to
damage that engine with the blades exposed like that. Given the rate
at which turbine engines rotate wouldn't the engine be subjected to
extreme stresses if one of the blades were to be damaged?

I was always told that the engine on a prop plane would probably get
ripped out of the mounts if a prop lost a blade so I don't think it is
good on any engine!




It will. one of the guys in my EAA chapter lost a blade on his Tailwind.
The prop was an "experimental" McCauley clip tip prop IIRC. The mounts
broke completely, but the cowling, throttle cable and what not kept the
engine on board. He deadsticked back to the field. The Navy called up
asking f anyone owned the blade later that day. it had landed in
someones back yard just missing the lady of the house as she was hanginr
her laundry!
It's happened many times over the years, in fact. There was one in
england where the engine on a Navajo shed a blade, the engine came off,
and the engine went over the top of the fuselage and took out the second
engine. the guy succesfully deadsticked the airplane into a field..

I was told that if the engine came out that you would probably be so far out
of CG you would crash tail first. So that surprises me that the Navajo made
it down under control.
