Steve,
What's your plans for all that non-bulkhead supported canopy and turtle. Cozy Girrrls too. Aren't you afraid of huge gaps or the things flopping like a pup tent at 180 kts and 10,000 feet?

Our canopy is designed to be as small as possible, the back edge is also canted forward. All the sealing surfaces are on shear surfaces not compressed surfaces. We have a lot of carbon. UNI and spar cap tape in the canopy, it does not flex.
When the seals are inflated they are not trying to push the canopy open.

They are just taking what Burt said literally... EVERYTHING MUST BE WHITE!

I'm almost done doing the prelim designs for my electric opening/closing and latching canopies.... with emergency release pins of course.

Now I just need to make the landing lights flash and the warning horn beep when the canopies fully close without a pilot inside

Canopy inflated seals? Tell us more!

Has anyone solved the water-leakage problem while parked and while in flight? This is one aspect of the design that really bothers me.

i am working on it as we speek.
i have cut back the under side of the conopy and glassed it and have added a seal to the turtal back.
i am installing the hooks and we soon see if the seal works
here are some pic's of the seal and the cut

Yes we did. Good yacht, oops aircraft design means you use drip edges (overhanging lips) and labrynth seal paths.

In the plans canopy you have 200 mph air blasting at the exposed edges, the joint is aligned with the airstream and to our knowledge the only sealing material that will work in this configuration is a Rubber V seal with the opening facing outwards.

For more protection and a drip edge if you are doing a forward tilting canopy then put a a bunch of layers of duct tape on the longerons going down the outside. Glass the outside of the canopy and let the excess go a 1/2" over the edges of the longerons. When you flip the canopy over glass the inside going down over the extended edge. Trim the overhang to 1/4".
Put the canopy back on and contour with micro up the side of the fuselage to make the overhang flush.

Water on the canopy should not get into the aircraft when parked.
Surprisingly it comes in odd places like in the engine compartment, runs down the firewall to the two wire harness holes, runs in along the wire harness to the back and front seat footwells.
