Program Description

"Ultralight Prepreg for use on Prototyping"

By Dave Ronneberg

TBD

"A summary of Blended Winglet results on Two Different Canard Aircraft"

By Marc Zeitlin

Jack Morrison added blended winglet joints to his gorgeous E-Racer, and obtained substantial drag reduction and efficiency increase. Chris Esselstyn added blended winglet joints to his gorgeous stretched COZY MKIV, and realized exactly zero drag decrease. Why the different results? We'll review the designs, structures and aerodynamics of the two aircraft, as well as the flight test results, and discuss possible reasons for the different experiences.

"State of the Art Technology brought to Experimental Aircraft Propellers"

by Craig Catto

A design and manufacturing slide show of the technology now used to bring a propeller to life.

Presenter's Biographies

A little about Dave Ronneberg:

Dave has built around 20 complete EZ type aircraft, more than anyone else. He has built 12 longEzes, 7 Berkuts and 2 Mobius aircraft His first design, Magna, was started in 1976. Then in 1980 he became a professional builder. In 1986 he designed the Berkut, which first flew in 1991.

A little about Marc Zeitlin:

Marc previously worked on cutting edge (and some not-so-cutting edge) aeronautical engineering projects for Scaled Composites. For three years, he managed rocket motor development for the Spaceship 2 program. Marc currently works for Icon Aircraft as Lead Systems Engineer, with responsibility for all non-structural aircraft systems on the A5 aircraft, currently under development. Marc has built two experimental aircraft (a Q2 and a COZY MKIV, currently with over 840 hours) and is a licensed A&P mechanic and an EAA Technical Advisor.

A little about Craig Catto:

Craig started flying sailplanes at age 13 and soloed at age 14, going on to getting his private pilots license and while also flying hang gliders from age 14.

Craig and his brother Chuck were amongst the first to put an engine on a hang glider that further evolved into the ultra light aviation industry. It was then that Craig made his first propellers back in 1974. Since then thousands of his propellers were made for ultra lights and since 1989 propellers for the homebuilt industry.

Craig's propellers have set world altitude records in excess of 82,000 feet and also dominate the Bi-plane Race Class, and his carbon fiber racing wings and tails dominate the Formula 1 Class at the Reno Air Races.

In the past 2-1/2 years Craig has moved his company into automated manufacturing with CNC's and design with full 3D Laser Scanners and CAD systems.
