Supergee type DLG build
« on: February 12, 2012, 14:01:25 PM »
So after the bones of a year off gliders I returned to the workshop.  I started to make a plug for a Quark 2m fuselage then found a bunch of materials I bought for another project and decided 1. Fred's quark is perfectly fine the way it is as a built up kit and 2. to start building some DLGs  :lol:

Design is standard Drela Supergee type affair.

Cut two set of cores on Friday. Took a few goes to get the file and the settings right but am fairly happy with the results.

Hot off the cnc


Trimmed, shaped and sanded


Packed the otherhalf and small one off to Engerland for a few days this morning so plan is to get stuck in and have them in the bag by this evening.
Mylars next....

If you heard a strange sound off in the distance earlier that was probably me screaming. Left my wings on the cnc table while i was cutting mylars. Computer was asleep. I pressed a button to wake it up and turned back to the mylars. Heard a sizzling and turned to see one of my wings melting! Long story short I was down a wing and not very happy   :!:  :!:

thankfully i cut two sets. :cry:  :cry:


Mylars cut


Making composite fabric. Kevlar and fibreglass


Ready to layup the wing


Finally in the bag


That was a lot of work. Should be a lot quicker next time as I have the mylars and kevlar ready to cut and i know what i'm doing a bit more(kinda)  :wink:

Thanks Alan. Did the layup on the table as the wife and small one are away. Then moved to another room for the bagging.

Fuse pod in the parting board ready to go. First side tomorrow hopefully. Got to keep going. If i stop it'll go back on the shelf for who knows how long!

I’m not sure exactly how you’re making these wings, :?:  presumably by vac-packing the composite onto the foam?
But that must mean you have a vacuum pump, yes?

Er …..west/ north winds for next few days Joe. It was a bit wet on the Big L yesterday :cry: . Are you gonna join me there before  the weekend? :D

K.
Try not to run out of airspeed, altitude and ideas....... all at the same time.

Thats a yes and a yes Keith.

Wonder if that wind is north enough for the North slope tomorrow? I'll be in touch.

A-Haaarrr! :?:  I have a task that would benefit from a vacuum pump. You see while you were ‘away’ last year,....... er,..... well just follow this thread and you’ll see what I mean

http://www.gliderireland.net/forum/viewtopic.php?t=1172&postdays=0&postorder=asc&start=30

I had been thinking of just using an “I” spar, but if you have a vac pump maybe you could help an old friend out to both “I” spare and glass the wing? ‘Belt & Braces’ perhaps but very strong wings non the less.

Let me know what time you what time you want to go tomorrow, :D  if you want to go that is. :?

So fuse has gotten resin and will do the laminate this evening when the resin has gelled.



So the wing.. Well the aim was to make something that is useable and I'm pretty happy that I've achieved that. It's far from perfect and I can see a few things I'd change straight away. Having said that it's not a millions miles away from the one I bought last year. They are a lot of work to make but the finish is really nice. Next one should be a lot quicker. :D  :D

Here it is out of the bag. Needs to be trimmed
