Airbrushed Cooling Plenum - Because, Why Not?

airbrushed-rivets

Here's a pretty bit of carbon fiber, a cooling plenum for the new Commuter Craft side-by-side canard. The air intakes are located in the high pressure area under the root of each wing. Rather than fool around with updraft cooling, nicely shaped ducts feed the top of the plenum on each side of the Titan IO-340. The cylinder baffles are conventional aluminum wraps.

The system seems to work very well. Company test pilot Ethen Chaffin reports 380°F cylinder head temperatures while maintaining 120 knots and an 800 fpm rate of climb, turning the three-blade Catto at 2450 rpm.

Yes, it's all carbon. The "rivets" and panel lines are airbrushed.

  2. Very Cool....would love to see more of the craftsmanship that was required to build that. Hats off to the artist in painting as well.
