Subject: | Re: 701 Top Window 7F19-1 bubble for more headroom |
I really don't think you have to worry about disrupting the airflow to the
tail by adding an airfoil over the cabin top. Tuft testing that we have
done show that the cabin top of the 701 stalls completely at about 46kts and
the airflow becomes totally turbulent, while on the Savannah with the full
airfoil of the wing carry-through, the airflow is still attached and smooth
flow right down to 26kts indicated. The Savannah has much better elevator
authority than then 701, right down to stall speed. Not only is it a
smoother airflow over the cabin for less drag, it's also generating lift
right down to that speed, while the 701 cabin top has lost lift much
earlier. We tried adding a partial airfoil over the cabin top, stuck
down temporarily with duct tape. Just at lift-off speed the trailing edge
ripped the duct tape loose and the panel flapped wildly and somewhat
alarmingly! You know how well duct tape holds, so this shows how much lift
was regained by that partial airfoil.... So Hans is planning to build a
permanent airfoil up there, (it's only that he's been pretty slack lately in
his retirement...). Can't really do a full airfoil due to the angle of the
windshield, etc, but anything that will ease that abrupt corner at the top
of the windshield and add curvature instead of the flat surface will be an
improvement. But it must be securely installed to cope with the lift
generated......

There is little lift produced by airfoil shapes over the cockpit roof.
Reduction of turbulence is why smooth shapes are used on upper surfaces. Lift
at any angle of attack are produced by air molecules acting on the bottom
surfaces of the wings and the fuselage. Bernoulli is a myth Newton got it

Subject: | Re: Gear fitting dimension |
Hi John,
I built the gear mounts, and yes either there is a discrepancy with
the drawing or my interpretation.
The gear leg calls for 3 1/4 material and then to file the bolt
reliefs which locates the gear transversely. I used 3 inch material
and still had to file the gear.
Is it not recommended to file the composite gear? If not, perhaps your
gear could be 3.250 between the mounts and say 2.875 on the legs
outboard of the mounts? side shift would then not be an issue.
What I've noticed in operation is that most of the gear flex happens
between the mounts and I would bet money that even the factory gear
mounts are 'as built'.

I'm really disappointed by the kind of teaching kids are getting these

data accumulated over
the years by an uninformed teacher in a classroom. Perhaps you'd like to
consider the Luscombe 8A bottom wing surfaces being at a slight negative
angle at best cruise of 105 mph or explain the rationale for carrying
such expensive airfoils on sail planes. Pity the poor first graders!
Obviously, you're jerking someone's chain here and I'm sorry I bit on it!.

My thoughts exactly, Larry. Thanks for taking the lead here. I do suppose,
however, that there is some upward force applied directly to the bottom
surface of the wing. This is commonly known as the barndoor effect. While
he has the players correct, Mr. Bernoulli's work is certainly not mythical.
Anyone with any practical wind tunnel experience would know.
I commend him on his efforts to inform the young about the theories of
flight, and even condone the simplification of the principles, but to
discount the airfoil is ridiculous. As is the idea that air is "hard". If
he is actually acting an any teaching role, the chain he is jerking is that
of the school administrators. Unfortunately, they probably don't know the
facts either.

Gentlemen and Ladies;
Before you waste time slamming me I
suggest that you buy a copy of Stick and Rudder by Wolfgang Langewiesche, read
the intro "Part 1" and Chapter 1 then at least then you will know where I am
coming from. From each of your comments, sadly, it is clear that neither of
you know why or how an airplane, or wing, flies. Larry, as to the
Luscombe's apparent negative angle of attach - nonsense - check the mean chord
line
it will be positive or the airplane will not stay up! Bob, Bernoulli is
easily disproven - take a sheet of writing paper hold it by the corners and
blow gently over the top, it will rise, then try blowing harder and you
will notice that it will not rise much more. Now, prove Newton by blowing
under the paper and the paper will rise with much less effort, with harder
blowing it will be almost straight out. The First Graders understand these
simple things as their brains are not yet addled with strange incorrect
theories.

Duct tape is also known as 100mph tape because it is an authorized repair f
or the tail surfaces of fabric covered aircraft with a VNE of below 100mph.
=C2-
=C2-
So in this case, it would not be an authorized repair becasue the 701 is no
t fabric, it was not used on the tail, and the VNE is over 100mph.=C2-

But hey, it is experimental aviation so all bets are off.

Subject: | Re: Gear fitting dimension |
Hi John;
I took a look at my drawing set and the actual Gear Mounts. On
sheet 7-L-2 item 1J shows the gear legs to be 82 mm wide with the notches
be 76 mm apart. The Gear Mount on sheet 7-F-17 item 1SP shows the mounting
threaded pins to be 77 mm apart. I measured mine and the pins were 76 mm
between them. The notches provide the lateral positioning of the gear so they
need to be there even with a composite part, I think that if they were
made 75 mm apart that should be OK. The Gear Mounts are a substantial part and
are probably welded in a fixture so I suspect they are pretty consistent.
The factory may be able to help with inspection data.

John,
If you're going to teach, you should at least learn to read and convey
what the author was saying about the theory of flight. The link below
brings you to the quotation
where he says that Bernoulli's principal theory is indeed correct and
true. It may not help the student pilot to learn to fly, but it is still
indeed true. Perhaps you should be
in another job where you can expound on things less difficult to read
and describe. Pity the poor first graders with a liberal teacher that
cannot pass along the truth.

"The plane floats on air like a boat floats on water." WRONG!!!!!
A lighter than air craft floats like boat floats on water, kinda!
Go back to school and take a physics course.

Well that was educational. Let's switch to which color Scotchbrite, VGs and
cheap rivets from China. Oh and let's not forget poorly flown aircraft
that break their wings.

Subject: | Re: Chat Reminder for "Digesters" |
for the Monday chat session try:
http://www.mykitairplane.com/chat/
It asks for a user name and password but the password is not necessary. The user
name is usually your first name and the plane you are building/own/fan of,
etc. The site suggests adding your home state but since we are Canadians, that
doesn't work very well.
Give it a try next Monday. There is usually a few guys on every week.

Thanks,
appreciate the info. Not very interested. Just frustrated of these hundreds of
chat mailings and reminders without any substantial input. I call it mailing
list SPAM.

Hey John,
Educational... YES.
I always thought that "MONEY" is what made airplanes fly. The more you spend the
higher and faster it flies.
Example:
$60,000 a fairly nice 12O MPH plane
$600,000 a little bit faster plane
$6,000,000 a faster plane.
$60,000,000 .... you get the picture ...
... and so forth ....

My thoughts,
From the Bernoulli effect, the increased velocity means that the pressure is
reduced at the top, and the decreased velocity on the bottom results in an increased
pressure.
The result is a net upward force.
I.E. Suck and blow?
