Designing FT-1 inspired wing- Looking to see if there is demand as well as suggestions for improvement

[Strych9]

Someone mentioned a DRS wing a while back on a different post. There seemed to be a tiny bit of interest but the primary conclusion was that no one would buy it. Either way, I'd still love to make one but I have zero interest in whether it would sell or not. My world is in prototyping and development, not production and sales.

I sat down with a buddy of mine and sorted out the actuation setup options. They were honestly pretty straightforward. Either of those would be surprisingly light for integrating it into a swan neck but I didn't look at what would be required for a pedestal mount wing. Once you settle on a way to actuate it, it's just a back and forth between trig and packaging, then just basic modeling and design work.

The idea is interesting but the packaging would be a nightmare to design around. Making it look physically acceptable for a street car would be a huge task as well, then making it affordable is another. People might want it if it were financially attainable.

One thing that would be viable in all aspects is a variable AoA wing ... that is something of interest that could be retrofitted to this wing, but thats a future idea

Some progress on the prints... over all came out nice... I've already made some adjustments to the trunk mounts... extended the base by 3mm... more thread for the studs to grab into on the cnc version and i added about 2mm of wall to the pocketing... None of that will require a reprint as it wont really affect the overall test fit.

top mounts in progress, risers after that.. then wing main deck.

Top mounts done

You'll notice areas of under extrusion.... thats because the extruder is trying to pull filament but theres resistance when it needs more... using 3kg spools. Looks bad but just test fitting so surface quality isnt a concern.

these made out of cf would feel indestructible. The prints feel really stiff, the real mounts would be insanely strong

 

[TheMaker]

Side A looking good... little size and design comparison from V1 to V4 now. 2 months of constant refinement. Im really liking where the design is now. It's really looking it belongs on the A90 (so far). Side B riser printing as of this writing. After that ill start with the deck. Since strength wont be a factor really ill save a lot of time on the prints. Coming together finally

Middle section came out looking great. This could definitely be a core for 1.5mm cf skin.
1/7 done

if i upgrade any of my equipment in the future itll be a new printer. Love my p1s but damn its a cramped build plate at only 256mm x3…. H2d or h2s is definitely on the wish list

Damn, add me to the list when final production is ready.

Appreciate the love! Keep you posted on updates 🫡

Wings nearly done printing. Some of the parts have some warping so i need to try flatten them as much as possible (its not bad but my ocd cant allow it lol). In the meantime Ive taken a reddit request to make the end plates a bit smaller and i like the outcome better in all honesty and ive make them 3mm cf so having them made will be mush easier. Have a 3d component appears more premium but adds more complexity to a part that honestly doesn’t need it.

let me know your thoughts on this

There is a relationship between endplate height, downforce, and chord width. I know there is a point of diminishing return with excessive height though.

I personally like either the basic square endplate design or a fully sculpted endplate but that's just me.

Yeah I noticed that in my testing... not huge returns unless you go excessively big... by moving the endplates up 5mm and scaled up 10% in size... I only saw 3 lbs of extra downforce and 2 lbs less drag... it all counts i guess but its negligible.

I like the basic look better too

I havent glued it together yet but these are the first prototype pics. Aside from the edge warping, it came out perfectly.
Seeing it for real is mind blowing…. seeing it as an actual product is going to be even crazier.

Ill try get it mounted on the trunk this weekend if possible. Still waiting on some hardware

 

[TheMaker]

Made shorty risers for this version of the wing -75mm and 35mm forward (roughly). Still waiting on some hardware for the test fit on the trunk.

The 3d printed wing is ready for test fitting so updates on that should be happening shortly. In the meantime I've been working on the model to make it production ready.

Deck Blade hollowed and cut in half. 1.5mm thick composite

Thread blocks will be added so the upper mounts thread in. itll most likely 4x M6 flange or countersunk. Theyll be positioned in a way that theyll be clinching with opposing force, so itll be very sturdy.

I still need to make the internal support structure but thats for another night

The first test fit was…..


successful!

everything just fit… i made a decent amount of tolerance for the studs to go through, and they did, but with a tiny but of resistance. Putting the stud on after the backing plate was not problem though. The studs were a little short in the front… i ordered 40mm length should be 50mm. But aside from that tiny oversight… it worked for the purpose of test fitting
Overall, its what i expected as i revised the CAD numerous times for a bang-on on fit.
