Oshkosh 2024 Forums and BatRay Progress
This issue goes out to 496 members of the Facet Faithful, currently subscribed.
Airventure 2024:
I will be at Oshkosh all week.
I will be giving 2 forums during the show.
They are both updated versions of the presentations I made last year:
Forum Schedule:
Monday: I will be talking about how to design a new airplane, starting from requirements to produce a completed preliminary design.
“How to Really Design an Airplane”
Monday, July 22, 2024
10:00 AM – 11:15 AM CDT
Forum Stage 8
Thursday: I will be discussing Low Aspect Ratio airplanes, including the the latest updates on the BatRay project.
”Low Aspect Ratio Sport Aircraft”

Forum Stage 4
I'm looking forward to seeing you all at the talks and meeting you in the Q&A afterwards.
BatRay Right Wing Riveting is Almost Done !
I expect to finish riveting the right wing in the next few days.
Once that is done I will move on to the center body, which is the last big airframe assembly:
So far I have removed over 25 pounds of clecoes from the wings and driven close to 1700 rivets (about 4 pounds total) . That is about half of the rivets for the entire structure.
Thanks to Dave Ullman for this pic.
I am designing a very similar lift body. I regret that I have only now discovered that someone else has been doing this successfully for many years! Many of the hypotheses I set for myself, you have proven in practice, especially in terms of flight characteristics. I thought that this type of aircraft had long been forgotten due to lateral stability issues. May I ask how you deal with the problem of lateral stability and flow, turbulent separation at higher speeds on the suction side, considering the overall geometry with a self-stabilizing airfoil? Unfortunately, I live in Eastern Europe and cannot visit you, but I would love to do so someday. Best regards, piotr.kochmanski@wp.pl
I've dug a little myself into this.
Sonex-B
A hardware kit costs $1550. If Cherry rivets cost $0.25 to $0.50 then there can be 3000 to 6000 rivets in it.
RV
I have found information that there are about 12000 rivets in an RV-8
