SNIP....

Tilt rotors are the future as they solve a lot of current car traffic and airport access problems.

This forum continues to hold my interest about Rotary engines for flight
powerplants.... but the extraneous conjectures about anything other than the
rotary engine tweaking causes me to shake my head in disbelief, my stomach
to turn, and sometimes, my mind to marvel at this scientific forum's
capability to conjecture and solve problems!!

OK... since we've gone off forum... here's my 2 cents worth!!

My, my, how we keep reinventing the wheel!!!    Maybe we should see how we
solved this problem in the 1940's and 1950's and determine if politics can
get out of the way of real world scientific progression!!!!

Hmmm... let's see now... what are the criteria???.....true VTOL, extreme
KISS technology, Zero energy roll out, almost 200 knot Vne, 40 passengers,
clam shell freight loading, SUPER safe landing with engine out events... but
no political backing...  ahhhh... there's the real failure point!!

50 to 60 years ago, other minds created fabulous quantum leap solutions to
our current discourse... as scientists, we can learn from the past, or
reinvent the wheel...

My stomach turns whein I see people beat themselves over the head
reinventing the wheel so much!!!

I continue to marvel at this forum's capability, and continue to find merit
in the rotary engine's tweaking.... but fixed wing solutions for societal
needs have been quantum leap outdated, since the 1950's!!!!!!

You guys keep slogging it out, I'll gleen the info I need from the rotary
engine discussions (since this IS a rotary engine for aircraft use
forum!)... ahhhh... such imaginations!! ... now if the collective forum's
mind was focused on rotary engine tweaking without diversion... hmmmmm!

ok... now back to the slogging!!   (Where's my Tum's delete button??)

I think you are missing a subtle point Gary. The Rotordyne had the same advancing blade
retreating blade problem as the helicopter. That limits the speed to about 200 MPH while a tilt rotor
has no such limitation and can go 100 MPH or more faster. Lockheed Martin is working on a
even faster tilt rotor than the Boeing-Bell version already going over 300 MPH.
The tilt rotor discussion is on here because the rotary engine's high power to weight
ratio makes an ideal tilt rotor power plant.
