REFLECTOR: DH engine vs. Velocity Beauty

[Keith Hallsten]

The DeltaHawk "A"-series or "inverted V" will fit in the standard cowl
designed for an IO-360.  That will take care of the top cowl modification.
However, it is not yet available.  In all likelihood, this will be an option
by the time you need an engine.

The consideration of the cooling scoops is a tougher problem.  It's in the
very nature of compression-ignition engines that they run hotter and have
more significant cooling requirements.  See, for example, the air intake for
the C-182 STC installation of the SMA SR305-230 turbo-diesel.  It's HUGE.
>From what I know, you will need a big scoop to keep a diesel happy.  (The
original SMA was liquidated last year after losing $millions$ trying to
solve the technical and marketing problems of putting their turbo-diesel
into planes.  The engine is coming back to market under SAFRAN Group, see
www.smaengines.com.  So far, it looks like DeltaHawk is having better luck!)

One of the reasons for which I chose the Velocity is its beauty.  Even 
though it is too early for me to worry about the engine, I'd really like 
to go for a diesel, most likely a Deltahawk 180HP or 200HP.

Looking carefully at the new pictures on Deltahawk's website 
(http://www.deltahawkengines.com), one cannot pretend that one does not 
see the huge intake scoops under the engine, as well as the fact that the 
DH engine affects the smoothness of the top curve of the fuselage (as seen
very well on this picture http://www.deltahawkengines.com/MT_Prop_14.shtml).
Both of these make the Velocity look much different, almost like a 
different airplane.

Is there any way to avoid changing the shape of the Velocity when one 
installs a DH engine, especially to avoid adding the bottom scoops?
Also, can the smooth curved shape of the top fuselage remain unchanged?
Finally, does anybody know whether the DH engine kit is available yet?

Best,
Grigore
