Re: Air Flow at canard - fuselage intersection LS1

David Richardson
 

That Quickie picture is one interpretation of how to make that
gill. I'm hardly a Quickie expert but I belive I've seen some that
are more squared or slightly flaired like a dust pan. That just
caught my eye because it looked like the oil on my plane and what
Jim's photos showed as well. To answer your question, I'm not
sure. What I have seen is a sloped ramp. I'm sure those NACA folks
looked at that configuration, though.

Paul's point about the CO making its way in via the NACA inlet vent
may be an issue. What I noticed on the oil that was sucked out of
the cowling was that it went under the bottom of the plane between
the aft surface of the canard and the main gear leg on my Tri-Q2 on
both sides. I did't see the left or right swirl exactly that Pat
was talking about. It just seemed to follow the area above the
canard and then gently rolled underneath.

I don't know if I answered your question or not or just gave your
more questions.

Dave, I made gills for cooling the Norton and have kept them for
the
Jabiru
3300 installation. I was not aware of Burt's work. I cut "D" shaped
panels
from the rear side cowl one each side and glassed the "D" reversed
inside
the cowl to make inverted "gills". I think they produce no drag and
located
in this low pressure area they work well. But I have retained the

Hi Jim,

I had similar results in some "unscheduled" oil flow tests on my
Tri-Q2
with an LS1. The specific point I saw was the arched clean area
about
4-5 inches above the canard / fuselage intersection. I always
wondered
what the air was doing right in the contour between the canard and
fuselage. Some had suggested that it was compressing the air there
which would cause drag and less of a V shape and more of an L shape
there would help. That is a compound low pressure area from the
canard
shape as well as the fuselage shape. In fact, it is low enough to
suck
loose oil from inside the cowling (hence my "tests"). You know I
think
Burt and co. really had it right on the Quickie by putting the
major
cowling exit air out over the canard through those gills. On the
Q2/xx
we try to dump the cooling air out into a high pressure area under
the
fuselage and we have these two nice low pressure areas. I'm sure
there
are other considerations, though. The Eagle 150 uses this area for
their cooling air exit.

Anyway, thanks for sharing the photos.

Re: Air Flow at canard - fuselage intersection LS1

Jim Patillo
 

Hello Sammy,

I believe you have the same style LS1 I have. Have you oil flowed the
canard/fuselage area of you plane?

I did and just published some pictures in the photo section. What am I
missing here? Did I not do the flow test properly? Isn't the goal to
have a canard fuselage junction that has a smooth attached uniform air
flow to the rear? I would presume if we have the same style canards,
they should behave similarily. In which case there may be no need to
revisit that area. Seriously what am I missing from my conclusion, I
always look forward to more work.

Regards,
Tell your lovely bride I said hi!

Re: Help!

As Sam says, the washout (twist) is set by the level lines.
You don't need the cord lines and you will not find them on any of the templates.
And you don't need to know the washout angles either, just use the level lines and you will build in the correct twist.

There is no sweep.

The anhedral is determined by the jigging templates, glued to your work

Any twist is defined by the template level lines.

Before you get out the saw, I have 900 + hours on a tri-Q with the anhedral still in and never had a problem on cross wind landings. I have tested it in 18 mph cross winds and have no marks on the wing tips. Ground effect picks up the tip before it touches unless you are doing some sort of extreme aerobatics (knife edge approaches etc.).

Wash out provides aileron effectiveness while the wing roots stall. One of the benefits of a canard is that it stalls FIRST. This means that the ailerons, on the main wing, NEVER stall. No wash out required.

(Sorry keyboard misfire on the last post.)

Here is a link to a Quickie photo.

http://members.shaw.ca/ghillsden/page5.html

The shape shown is a ramped channel cut into the side of the fuselage
with the thin end aft that contours over the canard and the thick end
inside the cowling. That contour example looks just like how the oil
flowed out of my cowling and over and above the canard area. If you
also look in the photo section of the Q-List you will see some Q2 fluid
dynamic images. The side shot shows the nice low pressure area above
the canard and aft of the firewall. If I understand this correctly,
having the ramp extend into that low pressure area will help draw the
air out of the cowling because it will be the path of least resistance.
If you also look at the fluid dynamic shot of the bottom of the Q2/xx
you'll see the high pressure area aft of the firewall in line with the
forward edge of the canard that most Q2/xx's try to dump their cooling
air into (the path of most resistance).

If you look at the Files section of the Q-List and open up the Side
Cooling folder Larry Koutz placed there you'll see what they did on the
Eagle 150 to get the air into the area above the canard as well as
Larry's manometer investigations of that area on his Q200.

Some of practical issues associated with actually implementing something
like this might be:

1) How big do they need to be?

2) Is there going to be any rudder pedal interference?

3) Keeping sufficient structure to keep that area strong and supporting
the firewall and canard attachments.

4) Possible streaks down the side of the plane from oil out of the
engine compartment

5) Getting the guts up to cut the fuselage and firewall

Re: Q canopies

Dave Richardson <dave@...>
 

I've heard Todd's Canopies can make a Q2 canopy and are reasonably
priced.



On the anhedral, I have it on my Tri-Q2 LS1 canard and I also trained in
one with it as well. I get some 15+ knot direct crosswinds pretty
regularly at my home airport and it has not been a huge issue. For me,
keeping the other end of the runway in sight after round out to help
keep the wings level has been pretty effective. I have drifted a bit
in the direction of the crosswind, though, but my runway is 100' wide.
I can't tell you why, but it does not seem to be as effected by
crosswind as the Cessnas I've flown. Perhaps it is the lack of a flat
side surface or reduced weathervane effect or something. I don't know.
My wife has been out watching me do landings on some crosswind days and
she will see the Cessnas hop and skip down the runway on one of their
main gear wheels and until they finally flomp down on the other two.
I'll follow right behind them and land level without the drama. Trust
me, I'm no hot stick. The Tri-Q just seems to be pretty reasonable in a
crosswind even with the anhedral.

Dave, I made gills for cooling the Norton and have kept them for the
Jabiru
3300 installation. I was not aware of Burt's work. I cut "D" shaped
panels
from the rear side cowl one each side and glassed the "D" reversed
inside
the cowl to make inverted "gills". I think they produce no drag and
located
in this low pressure area they work well. But I have retained the shroud
and
tunnel underneath. When the shroud is closed I get a cruise CHT of
239degF
when ambient is about 77degF. These gills show up in the pics file for
VHONQ
Oskar.

Hi Jim,

I had similar results in some "unscheduled" oil flow tests on my Tri-Q2
with an LS1. The specific point I saw was the arched clean area about
4-5 inches above the canard / fuselage intersection. I always wondered
what the air was doing right in the contour between the canard and
fuselage. Some had suggested that it was compressing the air there
which would cause drag and less of a V shape and more of an L shape
there would help. That is a compound low pressure area from the canard
shape as well as the fuselage shape. In fact, it is low enough to suck
loose oil from inside the cowling (hence my "tests"). You know I think
Burt and co. really had it right on the Quickie by putting the major
cowling exit air out over the canard through those gills. On the Q2/xx
we try to dump the cooling air out into a high pressure area under the
fuselage and we have these two nice low pressure areas. I'm sure there
are other considerations, though. The Eagle 150 uses this area for
their cooling air exit.

Anyway, thanks for sharing the photos.

Sam, are you talking about the small fillet at the wing root junction. Other
than a different paint job each of the 3 years I don't see any change to
anything in that area I have several photos of all the NXTs each year.

Take a look at the wing/fuselage junction on these racers. Pay particular
attention to photos of Nemesis and to Lee Behel, in the Lancair Legacy. I'm
going to do something like that with my Q-200 - someday.

Phil,

Mark is kind of quit. He's off working at Homeland Security in DC as
of last week. You may never see those pictures in the files. Should of
taken pictures when you were here. I said he claims 4 mph, I didn't
say he was getting it! We'll verify next time we fly together.
Although when he says something you can usually count on it.

With his fuel injected pumped up 0200 and this new mod he does have a
fast plane. Mark's made many inovations in drag reduction on his
plane, like cutting the kidney tank in half and keeping the engine
cowling flush with the bottom of fuselage, his own design for VG's on
the GU canard and this latest one. All these things make for a slick
plane.

Regards,
JIm Patillo N46JP Q200

Golly Jim! Is Mark another 4 mph faster? Are there any pictures of

Delamination

Allan Farr <afarr@...>
 

Has anyone else had problems with delamination of the fuse/tank floor? I have the tank out inorder to build a new leak-proof one (separate & removable), and the closer I look at the floor, the more problems I find. There is some unevenness (rippling) of the floor - how could this happen, isn't it factory built? Also a couple of areas where the inner glass has delaminated from the foam. I have removed most of the delaminated glass, and some of the foam which was contaminated with something that smelt like ether, but I wonder if patches are good enough or if I should redo the whole floor. As it is, I intend to clean up the areas concerned and reglass with a 3" overlap (& re-foam where it was removed).
