REFLECTOR: Vne (was 'interesting read')

[Chuck Jensen]

Al,
As the article discussed, if your IAS was 210 at 10K, your TAS, which is
what counts, was likely much higher, depending on temp.  Scott B. said
in an earlier post that the 200kts Vne for the Velocity was based on
flight testing by a test pilot.  I'm not sure how that works?  Was some
flutter encountered above 200kts, or was it just tested to 200kts TAS
and no flutter could be induced despite wacks and other upsets?  If
that's the case, then that doesn't say anything about 201, 220, 250 or
300?
 
Structurally, it would seem that the Velo has it all over the RV given
their respective +/-G ratings.  Flutter, though is markedly different.
I've not heard remarked of an incidence of flutter in the ailerons in a
Velo, though if the toe-in of the winglets is reduced too far, the
rudders will 'flap in the wind', as a couple have reported.  Maybe Scott
will weigh in with additional info.

I have flight tested my plane to 210 KIAS at 10,000 feet. Giving the 
stick and peddles multiple whacks. Seemed rock solid.
 
I guess I will have to test up to 24,000 when I get my turbo charged 
engine installed, as thats the turbo's limit for 100% output.

Scott;
 
Care to estimate the TAS that goes with the 210 IAS?
 
It would be interesting to know to what speeds folks have flown their
Velocities; either deliberately or otherwise.  It would also be
interesting to know about the flight data gathered (and configuration)
in the professional flight testing, and what the estimated margin is on
the suggested Vne.
