Vortilons

Wing Vortilons

Vortilon construction is detailed in the Roncz Canard plans since they are a mandatory addition to the wings if flying the Roncz Canard.  There was a well-known Cozy accident that resulted from a main wing stall due in large measure to the pilot/builder removing the Vortilons before a test flight.  Clearly these little guys are critical to safety of flight when incorporating a Roncz Canard into the configuration.

Now, as far as classification . . . although these are specified & mandated in the Roncz canard plans (canard = Chapter 10), they clearly go on the main wings (wings = Chapter 19).  So I’m adding them here as noteworthy item, albeit I’ll leave this page “chapter-less.”

18 October 2015 Since I had a little bit of pure epoxy left over from glassing the left canard swoosh tip, I grabbed the BID scrap box and a piece of plastic to make a 4-ply BID sheet, of which I would cut out a Vortilon or two.  I laid the 4 plies of BID into a pre-preg setup and poured all the epoxy into the layup.  After heating up the pre-preg with the heat gun it flowed well enough to wet out all the epoxy.  I then put another plate on top of it and weighed it down with my heavy tool bag (pic below).

19 October 2015 — Since I had used some leftover epoxy yesterday to make a set of Vortilons, today I wrote it into the work plan to finish the set for both wings.  Here’s the 4-ply BID layup for two more sets of Vortilons.

And here are the initial two that I cut from the glass I laid up yesterday.  These are the largest of the 3 sets of Vortilons.

Project Update

Hey Guys,  

Well, it’s coming up on about 6 weeks since I’ve been back on the build.  Made some decent progress on a lot of smaller tasks, and hope to be transitioning into some of the bigger airframe component builds here soon.

First off, I’ve been slowly organizing some of the info on my build log.  Essentially adding menus –such as Canopy Latch Hardware under the Chapter 18 – Canopy– in attempt to avoid having all chapter info lumped under one big page. Unfortunately, one of my last WordPress updates (I think is the culprit) reformatted my pics so they’re much larger in size, and thus have turned sideways to fit on various pages.  I try to update them a few at a time, but honestly this won’t be fixed until after this project is a true airplane.

While awaiting (initially) on some hardware for the canopy latch, I regressed into some tooling up in what I considered critical tooling systems required for my highly esoterically-designed (e.g. “one off”) components.  Those tools being my 3D printer, the plasma cutting table, and the milling machine.  The good news is the 3D printer appears to be back online.  The plasma cutting table is what I consider at bare operational capacity… it has issues on which I’m dealing with Langmuir Systems.  The major mods to the mill (besides CNC) are complete, and I can slowly start bolting it back together and get it operational.

So I’ll be transitioning back onto the canopy (Chapter 18) once again first, then with the remaining big build finishes: the nose (Chapter 13), followed up by the strake build (Chapter 21), and then knocking out the winglet/rudder install (Chapter 20).  All in haphazard synergistic fashion of course!

Cheers!
