Had a fellow inquiring about my
plane today who says he wants to turbocharge an ES. To my knowledge, the
only one flying is Ed Rosiak's, but I haven't heard how that TSIO-550
installation has worked out in the ES. In particular, I'm wondering how
the C.G. limits are kept within the design envelope with the extra turbo weight
up front. Since the ES was designed for either the IO-360 or the -550, it
tends to be nose-heavy anyway with the normally aspirated big
engine.
The Lancair factory worked on a
turbo-normalizing package for a while, but dropped it before it came to
market. Carsten was in charge of that effort, I think, but I never got an
explanation of why it was dropped. Size? Weight? Cost? Complexity?
All of the above? Also, would a turbo'ed ES exceed the tested flutter
envelope at, say, FL240? The wing is not designed for IV-type flight
conditions.
Any comments or insight on
this?
