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.



Well, only one of them came off. the other just quit.
You're right, though .On a single you would have little chance. There
was a Stearman that the engine came off of and they did make it, or so
the story went.
The Navajo wasn't all that long ago. there must be some pics somewhere.
