and carburetor heat knobs and the presence
of a push-button starter.
The engine springs to life instantly
when the starter is engaged, and it
responds quickly to throttle adjustments.
O'Donnell said the onboard computers
actually slow the engine response to
avoid the high torque and P-factor that
can result from a too-quick application
of full power (such as a student pilot performing
a go-around).
Switching the key position from
normal to auxiliary power tests both
electrical systems, and the pilot can
move between them manually or let
the onboard computer system do it
automatically.
Takeoff acceleration was quick
despite a 7,000-foot density altitude,
and the airplane climbed at an impressive
1,000 fpm with two aboard, half
fuel, and more than 100 pounds of ballast
meant to keep the airplane near its
maximum gross weight.
" That's about twice the climb
rate you'd get in a brand-new 172, "
O'Donnell said.
A pair of intentional go-arounds
with the flaps set at 30 degrees showed
smooth and rapid throttle response and
quick acceleration that required pitching
the nose up within a few seconds to
avoid exceeding flap speed-something I
didn't anticipate in a normally aspirated
172 at high elevation.
The propeller on the Corsair V-8
spins in the opposite direction as those
powered by Lycoming or Continental
engines, so the pilot applies left rudder
during takeoff and climb. Approach
and landing at 65 knots felt normal for a
heavily loaded Skyhawk.
The Corsair 172 is currently registered
in the experimental category
(market survey, research and development,
and crew training).
O'Donnell said he is convinced a
modern automotive engine is the right
fit for GA right now.
" Electric propulsion looks promising,
but it isn't ready for prime time, " he
said. " Traditional aircraft engine manufacturers
don't have the economies of
scale that come with mass production.
Taking a modern automotive engine and
adapting it for aviation seems like the
right answer. dave.hirschman@aopa.org
