Subject: Re: The Obsidian Files - Wing Tips
From: "dmac7" <dmac7@outlook.com>
Interesting what a computer can say about shape changes on a aircraft. The B model
Piper Aztec offered optional 22 gal tip tanks of a different shape to the
standard wingtip. It was said they were Hoerner wingtips.
With these Hoerner tips the Aztec would land a few hundred feet shorter and cruise
5 mph faster. Similar but not the same as your Chamfered tips.
The Aztec had a non tapered planform and thus was full cord at wingtip, this may
have exaggerated the improvement. The comparison Aztec was a C model with standard
round planform wingtips. Old memories.
