This
is my first try at posting, so I don't know if it is as easy as sending an email
but here goes:
My
Lancair 235, from 8500' MSL over open water in the Bahamas with 2 180lb persons
and 50lbs baggage lost a propeller tip (wood prop). Climbed slightly and
cut power to idle, was back at 8500' by the time I stabilized. From that
point we glided over 20 miles over open water to land. We may have had a
bit of a tailwind, but if so it wasn't much.
I'm
not an aeronautica engineer, but at 120mph IAS my ROD was only about 750-850 fpm
- slow enough so that I chose to do a high downwind entry rather than a
straight-in.
I'm
wondering if the figures below were fully configured? I got gear on short
final..
Story,
as told by my passenger, here:
Bill
My Lancair has extended wingtips. Span 25', 77.1 sq. ft.,
8.1 AR, 0.82 Oswald, 1.5 sq.ft. drag area*,1000# empty, pilot + fuel 350#.
Best L/D 104 mph IAS, ROD 1370 ft./min.
45 deg. turn at equal parasite and induced drag, 123 mph
IAS, ROD 2300 ft./min., turn rad. 779', 13.6 sec. / 180 deg., altitude loss 519'
/ 180 deg.
45 deg. turn at 76%, 94 mph IAS, ROD 2020 ft./min., 318'
turn radius, 7.3 sec., altitude loss 244' / 180 deg.
* My data. This is equivalent parasite drag
area only, and does not include induced loss.
