Better than TKS?

[thinwing]

Hey Jose..why dont you try this stuff out on a nice winter day with frontal passage on a flight 2 or 3 thousand above freezing level and report back how well it worked!!No fair testing out over Bahamas or Baja California in summer!!I await your report..kpc

You know what's even better than TKS?

The skin friction generated from 400+ kts.....

Sign me up for the testing of that, M016576!

You mean like this?  

 

 

I used to fly a Sabreliner 65 and they didn't have any ice protection on the tail at all.

Show off!  :-)

 

How about the skin friction at 600kts and excess power >20,000fpm to get out of there if you wish?

One thing worse than no ice protection at all is a home made half baked de-ice system that doesn't work, but lulls you into ice only to discover that the pam/rain-ex home made concoction on your wings either doesn't work at all or works slightly and encourages some unwanted behavior like run-back.

Exactly. By protecting the leading edges only with coating, the super cooled water would simply flow back into the boundry layer and form a nice little dam on both the top and bottom of the wing exactly where the coating would stop. I'd rather take ice on my leading edge where at least the behavior is predictable, at least on a Mooney, at least up to about an inch.

 

TKS is expensive and can be a pain in the butt but it works. I've been making almost a weekly run this winter between KCBF and KFAR. I don't know what ice looks like. The prop spray more or less protects the entire airframe. The only place I ever see any ice is my landing gear after an ILS approach.

 

What I loved about the TKS is even when my engine decided to dump all the oil overboard at 8000 about 6 weeks ago, see my galery, I still had deicing fully functioning to get me down and back to the airport. Boots would not have helped me much. I've always wondered about Pilatus and TBM. Yes, they are both gliders but should you lose your engine at let's say 25,000 that's a long time in cold, wet clouds with boots that no longer function.

there are a few YouTube videos out now demonstrating NEVERWET spray on coating.

 

1. It turns the surface a milky white color

2. It dries to a rough finish

3. It doesn't last long under pressure or from constant abrasion.

 

Best one I saw was the bottom surface of an RC race boat coated with the stuff.

Uncoated speed trial got a top speed of 43 mph 

Coated speed trial got a top speed of only 37 mph

Much of the coating was gone from the bottom when the speed trial was finished.
