Fixed pitch (i.e. not featherable) props.


I've always wondered about "cheap" ways to get rid of prop drag on a
multiengine plane when one engine goes tits up....

Anybody ever looked at explosive bolts for ditching a draggy prop?

take care

Bill,
I have often thought about this also. Featherable props are
expensive and it would be good to get around them. For a pusher
installation, has anyone considered trying to develop the type of prop
that Europeans use on some of their powered sailplanes, that being a
folding prop. When the engine becomes " dead " the prop would fold
back into the slipstream and lose it's drag. The prop would again
fold back to it's normal position due to centrifigual force when the
engine is tried to re-start. I have even seen props that fold FORWARD
on some of these sailplanes, but I can't figure out how they get those
to work.
