New Baffles Keep Bonanzas and Barons Cool

D’Shannon Aviation has developed new engine baffle systems for Beechcraft Barons and Bonanzas, designed to eliminate any loss of cooling air through the cowling and maximize engine cooling. The new Baffle Cooling Kits consist of engine-mounted aluminum baffles with high tear-strength silicone, and these mate with composite inserts attached to the upper cowling. During development the new baffles were flight-tested in ambient temperatures as high as 100 degrees F. The new kits fit Continental IO-550, IO-520 and IO-470 engines on the Bonanza and Baron.
