Gee, I better start ground school again.

I always thought lift demons were actually pushing the Earth from
underneath the airplanes when you pointed the empennage downward.
(Although it might be still the case here in Canada. We are a weird
bunch up here, anyways...)

Hesitation point rolls are a lot of fun for a pilot watching lift
demons. It's an absolute riot to watch them scramble off the wings and
onto the fuselage then back again as the roll progresses. The most I've
ever been able to disturb them this way was 16.
Australian lift demons can't seem to figure out which side of the wing
to climb onto when they're here in the states, but they get even when
ours opt for an outback vacation on their time shares.

I actually wrote something almost serious about this amazing 'new'
theory, but most posters have dealt with it so much better that I shall
leave it as a draft.

I love the lift demons, although my aerodynamics lecturer did not give
me a good grounding in them I am afraid. Next time Dudley you must tell
me more. Are they related to the RAF's Gremlins? They were good and
bad. The good ones helped hold badly damaged aircraft together until
after they landed in WW2.

While the general aviation community is for the most part unaware of the
vital role played by Lift Demons, the FAA has for a long time taken them
into consideration when formulating Federal Aviation Regulations. In fact,
understanding the needs and wants of Lift Demons greatly helps in
understanding many of the rules that the FAA has introduced over the years
(which otherwise make little sense to the average pilot).

For example as it turns out there are two types of Lift Demons. Bird Demons
and Bat Demons. Bat Demons are blind because they evolved along side bats in
caves, they also have sticky feet which help them to grip onto the more
slippery wings of bats. Now, when man first took to the skies, it was on the
wings of bird demons (Seagull demons to be exact in Kittyhawk). However,
before long some bright sparks decided that unlike birds man would fly his
airplanes inside clouds (not something that birds usually do - I mean have
you ever seen a bird inside a cloud ?). Straight away there was a problem.
Bird Demons need to be able to see where they are going and when they can't
see they get scared and quickly jump off the plane - causing unfortunate
accidents. Should you every fly into a cloud by mistake - quickly start a
180 degree turn to get out of it before the Lift Demons panic. However,
before long a solution was found, Bat Demons, being blind didn't panic
inside a cloud, they didn't need to see in order to keep the lift working.
As a bonus, their sticky feet helped them grip wet slippery wings which is
common when inside a cloud. However, there are not very many Bat Demons (at
least compared to Bird Demons) so you need to make sure some Bat Demons are
waiting for your plane at the runway before you take off if you are planning
on flying into a cloud. The FAA realized this and created the Air Traffic
Control system to facilitate the timely coordination of Bat Demons and
planes. And that is why FAR 91.173 exists

Sec. 91.173

ATC clearance and flight plan required.

No person may operate an aircraft in controlled airspace under IFR unless
that person has--
(a) Filed an IFR flight plan; and
(b) Received an appropriate ATC clearance.

You see, when you file an IFR flight plan the flight service station
computer sends a message to the nearest colony of Bat Demons telling them
where and when they will be needed. Actually, the demons we all know that
live inside computers can communicate directly with their demon brothers -
so the Bat demons don't need their own computers. The Bat Demons don't
always turn up on time, which is why you can't actually take-off until ATC
sees the Bat Demons arrive and issue your IFR release. Sometimes, when the
weather is really bad and lots of planes want to fly in the clouds, there
are not enough Bat Demons to go around and you have to wait a long time on
the ground for some to arrive.

It all starts to make sense when you think about it. Bird Demons don't even
like getting close to clouds. That is why you always have to ask ATC for
Special VFR, this gives them a chance to call up at least a few Bat Demons,
to keep all the other Demons calm as you fly close too the (but not in) the
clouds. Class bravo airspace has so many big jets flying with lots of Bat
Demons that there is always a few extra around which lets you get closer to
the clouds as well.

The current theory of flight is based upon the Bernoulli's Principal, the
pressure of a fluid (liquid or gas) decreases at points where the speed of
the fluid increases. The airfoil is designed to increase the velocity of
the airflow above its surface, thereby decreasing pressure above the
airfoil. Simultaneously, the impact of the air on the lower surface of the
airfoil increases the pressure below. This combination of pressure decrease
above and increase below produces lift. Pressure is reduced due to the
smaller space the air has above the wing than below. Air cannot go through
the wing, so it must push around it. The surface air molecules push between
the wing and outer layers of air. Due to the bump of the airfoil, the space
is smaller and the molecules must go faster.

Hey, don't mess with the mechanics of flight. My airplane was built in
1966 and I don't want to have to buy a new one.

THIS HAS A MAJOR PROBLEM - specifically inverted flight. The current theory
of flight utilizing the Bernoulli's Principal is only applicable to normal
level flight. However, we know and observe that inverted flight is
possible. Thus, the Bernoulli's Principal is no longer applicable to
inverted flight, so there must be another theory that supports flight, be it
level or inverted.


The new theory of flight is based upon the new theory of Gravitational
Vector Force (released Sept 2004). Utilizing Newton's laws that equal
opposite force is generated at right angles, be it applied at once or
successively, and if the angle is oblique (slanted) a new force is
generated. Then inverted flight is possible as force is always generated at
right angles, and this is towards the ground in all cases. The net
difference between the initial velocity and resistance force generated at
the leading edge at right angles (downwards) creates a new force called
Gravitational Vector Force, and it travels in the opposite direction
(upwards) to maintain balance, impacting the bottom of the wing. The wing
becomes less efficient in inverted flight due to the design of the airfoil,
however it is still possible.

This new theory of flight also supports the following;
1) the new force manifests at a faster rate than initial velocity, hence the
wing becomes more efficient at faster speeds
2) As you extend spoilers and flaps at the leading and trailing edges, the
bottom of the wing now becomes "cupped" like a satellite dish, and able to
capture more Gravitational Vector Force, creating more lift

You may read more about this new theory at www.threexd.com

I'll probably skip reading it, thanks. Ah, where to start?

One observation.: If "cupping like a satellite dish" helps to increase
the gravitational vector force, then why don't you build an airplane
with a satellite dish shape instead of wings and see if it flies?
Might be a good test for you... I'll stand well clear on the ground
if you please. I don't think you'll get above the runway, but I want
to avoid being near a ground accident.

Bernoulli's theory is an expression of constant energy. The air
stream has pressure and velocity, if the velocity increases, the
pressure decreases unless you do something to add energy to the
airstream. Note that the increased pressure on the bottom of the wing
is less contributory than the decreased pressure on top, unless you're
at a high angle of attack.

Bernoulli is one way to describe what happens to the air passing over
and below a wing. For a more complete description see an aeronautical
textbook. I like "Aerodynamics for Naval Aviators", available from
ASA and other providers. Also the online book "See How It Flies" has
a good description at http://www.av8n.com/how/.

Basically, the wing works by pushing down a large volume of air. The
equal and opposite reaction pushes the plane up. That's the simple
version and to my own mind a much better and less confusing starting
place than Bernoulli.

And, I probably wasted my time replying to this in any case.

That's what Bernoulli's Superintendent is for. He takes care of all the
really tough situations.

Mark,

Nice job, your troll post has snagged a lot of responses... very effective post.
