I will be presenting "Drag, Speed and Prop Design" (or power and drag..) at Airventure 2012, Friday 27 July, 11:30 a.m. in the Homebuilder's Hangar:
What comes after the Norris Zero Thrust Glides? 2010's talk was about how to find your airplane's drag curve. 2011 was the Triangle Tool & how it helps with prop design. This year's will present Version 3.1 of the Triangle Tool with an induced drag cross-checker, flight test methods and case studies from real life, including the NASA-CAFE Green Flight Challenge. There may be some good stuff on practical horsepower testing on-airplane, too.
I will put the slides on my website ahead of time, but the real value of the show will be the show & tell part with live use of the tool.
If I can get a dozen to come, it may break last year's attendance record. Consider yourself invited.
