Hartzell Propeller has acquired substantially all the assets of WhirlWind Propellers Corporation, so expanding its product portfolio into light-sport aircraft.

Founded in 1995, WhirlWind Propellers manufactures composite constant-speed and ground-adjustable propellers for the light-sport, experimental and unmanned aircraft markets. The company also designs proof of concept propellers for emerging applications. Hartzell Propeller plans to retain the WhirlWind brand and product offerings.

JJ Frigge, President of Hartzell Propeller, says, "The acquisition allows Hartzell to further expand WhirlWind's rapid propeller development capabilities for the design, tooling and manufacturing of advanced carbon composite propellers."

Hartzell will retain the services of Jim Rust, former President of WhirlWind Propellers. Rust's technological expertise with rapid prototyping composite propeller systems further enhances Hartzell's existing capabilities.

Rust says, "I am excited to be part of the Hartzell Propeller team and eager to see the WhirlWind brand continue to thrive under Hartzell's leadership."
