PIQUA, Ohio — January 29, 2002 — Hartzell Propeller has been selected as the recommended propeller supplier for Lancair’s Legacy 2000 kit plane. A new Hartzell propeller has been designed specifically for this application and will be used on the first completed Legacy 2000 kit as Lancair’s Chief Engineer Carsten Sundin attempts a record setting around-the-world trip in early 2002.
The Lancair Legacy 2000 presented an especially challenging design task because of its strict requirements for small diameter and low weight with relatively high power input and a goal of achieving very high cruise speeds. In response to these difficult requirements, Hartzell developed a 2-bladed 72-inch diameter propeller for this application. The 7694-4T model blade was designed to provide an efficient blade loading distribution at the high cruise speeds expected from the Legacy 2000, while still providing adequate climb performance. The propeller blades are also relatively thin and have a swept tip to reduce noise.
In a unique move based upon the proven performance delivered by the Hartzell prop, Lancair requested certification testing from Hartzell for the two different engines they offer for the kit. Hartzell performed vibrational stress testing on each engine and approved specific versions of this propeller for both the 310hp Continental IO-550 and the 260hp Lycoming IO-540. Hartzell has also approved a version for use with the 300hp Lycoming IO-540 as well.
On the occasion of Lancair’s first flight of the Legacy 2000 in March, 2000, a Lancair news release stated, The incredible new Lancair Legacy 2000 has upped the ante once again by using a 310 hp Continental IO-550. The aircraft flew flawlessly with company pilot, Orin Riddell at the controls.
“Everything was what we expected and more! I saw over 280 mph TAS at 8000 ft and expect over 300 mph down low!” said Riddell. “Weight and balance was well within the envelope with the bigger engine. Having Hartzell Propeller design a new lightweight propeller helped make this possible. The aircraft was only 90 lbs. heavier than the previous configuration, which used a turbo-normalized Lycoming IO-360. Lancair already has orders for over 150 kits.
These propellers are perfect examples of Hartzell’s unique ability to provide mission optimized performance for our customers, stated Mike Disbrow, Hartzell’s Senior Vice President Marketing, Applications & Customer Support. Our success in meeting our customers needs can be directly attributed to our outstanding engineering team, design tools and flexible manufacturing processes.
