FLOAT PLANES

Let's see your float/sea plane.

This is the ICON A5 Light Sport Aircraft. This was in a banquet room at a hotel, so it really doesn't do the plane justice.

I've seen this plane, I believe.

coming in to land in Vancouver Harbour

Long ways from the ocean but...

Lake Buccaneer (I think...)

Actually John, I'd say the fact that an aircraft was in a banquet room in a hotel to begin with does it great justice!

I think most of my floatpanes and seaplanesand amphibians are on film, need to get those negatives scanned someday.
Twin Otter in #1 and #5, #5 I can tell was taken in Seattle, #3 is a Dehavvilland DHC3 single Otter with a Vassar Turbine engine conversion, I was Kenmore Air's Chief Inspector when this aircraft was converted along with 3 other. Prior to my time at Kenmore, I was the maintenance manager for the west coast Lake amphibian service center in Renton Wa. so I can confirm #6 is indeed a LA-4 Buccaneer, inside joke was any time we landed in one we would say we "Buccaneer made it"
I have quite a bit of time with Grumman amphibs, as well as Republic Seabee's...I'll have to search my files and see what I can come up with.
Thanks for te memories.

Love the DHC-2 Beaver shot up there. I am currently assembling a remote control model of one - great to see a real one in the air. Thanks

Caught the vortex coming off the prop of this floater starting to land. Very overcast, humidity at 100% day in Ketchikan Alaska.

Anyone know what those little things are on the leading edge of the Seawind's wing?

Here's one on dry land (For the moment, anyway. )

They're called "Vortex Generators" and they modify the airflow over the wing (although I'm not exactly sure in what way.) Typically, VGs help keep the wing from losing lift due to boundary layer airflow issues at higher angles of attack (which can cause a stall.)

I guess the manufacturer found something beneficial about making seperate convergent streams of air (or divergent depending on how you look at it.)

VG modify airflow over the wings due to distruption of the straight airflow providing lift. That was an excellent photo Denny.

So taking into account the usual things that happen with a traditionally mounted tractor prop on a land-based airframe:
- P Factor
- Torque
- Gyroscopic Effect
- Spiral Slipstream

What's so different with a pylon-mounted pusher prop on a plane that can use both hard-surface runways and water such that they have to mechanically stir up the boundary layer?

Hmmmm.....?
