New Baffles Offered As Laser-Cut Installation Kits
Sonex Aircraft, LLC tells ANN it recently introduced two "cool"
new AeroConversions products, in the form of improved cooling
baffles for AeroVee and Jabiru engine installations. Both baffle
systems will be offered as laser-cut installation kits designed for
use in Sonex aircraft, yet easily modifiable to aircraft with
similar cowl designs.
The systems provide dramatic improvements in cylinder and head
cooling due to their increased volume, giving a larger plenum of
cooling air and slowing airflow through the cowling. This decreased
airflow velocity allows more efficient transfer of heat from engine
cooling surfaces to the transient cooling air.
"While our previous cooling baffle designs provided adequate
cooling for both the AeroVee (above) and Jabiru engines in all
factory tested scenarios, these new systems offer a much wider
margin of cooling efficiency and greatly reduce opportunities for
unacceptable cooling situations due to installation error," said
Sonex General Manager and CEO Jeremy Monnett. "We are continually
working to improve our excellent technical support resources and
refine product development to make a successful Sonex Aircraft
building and flying experience even easier to accomplish by every
homebuilder."
The new AeroVee cooling baffle system is a completely new "fence
baffle" design, which has been demonstrated to reduce maximum
cylinder head temperatures up to 80 degrees on AeroVee powered
Sonex Aircraft. The new Jabiru baffles are enlarged versions of the
previous AeroConversions "box baffle" design, and have reduced
maximum Jabiru 3300 cylinder head temperatures as much as 70
degrees in Sonex flight test aircraft.
Both cooling baffle systems will include laser-cut 6061-T6
aluminum baffle components, along with all rivets, extruded
aluminum angle stock and most other items required to achieve a
typical installation. The baffles will also ship with a full set of
detailed installation instructions.
The AeroVee baffle system is priced at $100, with the Jabiru
Baffle systems (shown above and below) priced at $250 for Jabiru
2200/3300 installations. Customers who have previously purchased a
Jabiru Baffle Kit from Sonex can purchase an upgrade kit for
$100.
Sonex provides a series of Sport Pilot eligible kit aircraft.
Its AeroConversions line of products includes the AeroVee engine,
AeroCarb and ancillary aviation products. Sonex and AeroConversions
product development is committed to providing simple, elegant and
low-cost solutions for sport flying.
