PIQUA, Ohio — June 23, 1999 — Hartzell Propeller Inc. announced today that its 93-inch diameter three-bladed aluminum, fully reversing turbine propeller system for the Turbo Raven recently helped the aircraft achieve a series of new world climb records. The Turbo Raven is a highly advanced, light weight carbon graphite based aircraft intended for high performance airshow work.

Piloted by airshow performer Wayne Handley, the Turbo Raven set new records for time to 3,000 meters of 1 minute 9 seconds, and bested all other propeller driven climb records. Previous climb records that were broken included the turboprop class record of 1 minute 48 seconds set by Chuck Yeager in a Piper Cheyenne 400LS and a turboprop sub-class record of 2 minutes 18 seconds set by an Allison powered Bücker Jungmeister. Handley also beat the all time propeller-driven climb record set by Lyle Shelton in a highly modified Grumman Bearcat of 1 minute 31 seconds. Upon completion of the successful attempt, Handley said “… that propeller was diggin like a prop in water … it was a rocket.”

After setting the new record, Handley wanted to improve the aircraft’s performance for his airshow routine. Hartzell was able to increase the aircraft’s static thrust by a whopping 34% by changing to a very wide-chord, 100 inch diameter three-bladed composite propeller. With this added performance, the Turbo Raven now has a static thrust-to-weight ratio of almost 1-1/2 to 1 allowing it to perform what Handley describes as a Vertical Stop and Go maneuver, where the aircraft climbs vertically-stops-hovers-and then continues the vertical climb. After trying it for the first time Handley said, “the power of this prop is amazing!” This new prop will also be used to attempt the 6,000-meter climb record on July 31 at the EAA Airventure 1999 at Oshkosh.

Hartzell Propeller Inc. is the world’s leading manufacturer of propeller systems, shipping into more than 25 countries in 1998. Hartzell enjoys a 60 percent market share on turboprop airliners and 85 percent market share on corporate turboprops. The 82-year old company is also well-known for its design leadership, having introduced the industry’s first full-feathering propeller for light twins, the first fully reversing propellers for corporate turboprops and the industry’s first composite structure blades.
