Here is an interesting subject that I have not seen discussed in my
years on this list.
Has anyone tried to duplicate the overriding clutch or whatever it
is/was on the "twin pack" rotary set up done by that European outfit
several years ago? Can't remember the name (Swiss company?), I think
they are out of business. Anyhow, it seems a very elegant solution to a
high hp redundant twin, esp for helicopters or even a large cabin class
craft.
How did that tranny work? The engines were side by side.

BTW, any word on those PT6 gear drives?
