Canard Ice Shields Ver2

Canard Ice Shields Ver2

Blog, Ch 10 Canard
Date:  07-19-2020
Number of Hours:  10
Manual Reference:  10

I’m not even sure where this is in the plans but I do know an ice shield for the canard counterweights is needed. Without it the canard could freeze in position if I ever get stuck in where ice forms and can’t get out. Sure the whole plane will freeze eventually! I understand those counterweights would be first to go so it is prudent to add the shields and delay a possible issue.

As I have a flying Long-EZ with these I went out and took a couple of pics.

It looks like the idea is that you direct all that icy cold air over the counterweights so it can’t get in easily and freeze them in place. The 1″ height allows the counterweights at full elevator deflection to be shielded, but why the stumpy design?

Here we are on my new build canard and I’ve sanded a block of foam to the bottom contour.

Now I’ve sanded to a more aerodynamic shape and a little longer. I bit like half a blue carrot?

I used two ply of BID and held the edges down with taped sticks to get a crisp edge.

Functionally similar to the first example but more streamlined.

Yes I do have my bare sanded canard and wings in thick plastic. Its getting cold here and moisture condenses on the hangar roof interior girders and it then rains a little inside right over my build some mornings!

I’ve sanded them but left the blue foam core inside for now. I’ll remove that when its time to silicone them in place after the canard is painted. I might trim the edges a bit more too.

I’ve got these done now so they can painted easily at the same time as other things rather than a separate job much later..
