Tennessee Propellers, Inc. has been producing quality wooden ultralight
aircraft propellers for microlights and powered parachutes since 1981. Tennessee
Propellers, Inc. is also the world distributor for Zenoah two cycle engines. All
T.P.I propellers are manufactured from multi-laminated hardcore maple veneer.
Laminations are bonded with CLASS1 waterproof resin. Our blanks contain 24 to 48
plys depending on the thickness required.
Carving to pitch, the most important step in propeller making is done on a machine to
insure that both blades will have exactly the same shape and pitch. After carving,
each prop is hand-sanded to remove any machine marks. At this stage, preliminary
balancing is done.
Wood sealers are next applied and again re-sanded. Each stage of production from
the wood laminations to finished propeller is subject to a series of inspections.
Final balancing is now performed.
T.P.I. propellers are given their final finish in multiple coats of unique two
component polyurethane coating containing aliphatic polyisocyanate. This coating was
especially formulated for the severe environment to which propellers are subjected.
The surface is extremely hard, yet flexible to protect against nicks and abrasion.
It has high gloss retention properties superior to conventional urethanes.
T.P.I. is pledged to provide individuals, dealers, and manufacturers with a product
they can count on at a reasonable price.
Propellers can be ordered in hub thicknesses of 1.5", 1.75", 2", and
2.25" and up to 72 inches in diameter. We also manufacture gyrocopter
propellers of 3" Hub thicknesses and up to 66 inches in diameter.
