Default Very long boring technical discussion of Lift Faries adn Thrust

If you feed the gremlins hot chili with lots of beans, the
rocket like exhaust provided lift and propulsion.

| OK, Jose (just had to say that one) explain delta wings.

| Oh, that's a tough one. Looking at the CAD drawings, I
was at first
| inclined towards the helicopter methods (it's ugly; the
earth repels it)
| but the composite of several deltas belies that
simpleminded conclusion.
| It resembles a bird in flight, maybe the air can be
fooled into
| thinking feathers are on their way... but that requires
the air to do
| the lifting. We know this can't be true. Obviously some
out-of-the-box
| thinking is in order. Fortunately I'm up to the task;
people have been
| trying to put me back in my box for ages.
|
| I am drawn to the 200 mph cruise speed; this is pretty
fast for a single
| engine prop plane. Maybe we are thinking this whole lift
thing
| backwards. An airplane's natural habitat is the air, and
it =wants= to
| go into the air. Very often what brings airplanes down
are gremlins,
| usually traced to the control system, the avionics, or
even the pilot
| himself. The object of the propeller is to shake the
gremlins off the
| plane and allow the plane to achieve its natural state.
Since gremlins
| are pretty fast, the airplane has to also move forward to
keep them off
| the plane.
|
| This is a homebuilt, which is the natural habitat of
gremlins. So, it
| has to move =very= fast in order to shake them off and
keep them off.
|
| When you consider how hard gremlins are, and how soft
feathers are, it's
| a natural that feathers repel gremlins, and lift is
sometimes
| erroniously attributed to feathers. Many researchers have
been down
| this path, and there is a large body of accepted
literature in support
| of the feathers theory. At low speeds, the feather theory
and the
| gremlin theory give pretty much the same answers, but at
high enough
| speeds the relationship breaks down and the feather theory
gives
| erronious answers. This is where gremlin theory shines
(it should be
| noted that lift fairies are just gremlins gone bad).
|
| Gremlin theory holds the potential for explaining a lot of
aviation that
| is otherwise unexplainable, but experiments are difficult
and fraught
| with peril. However, I would be happy to conduct the
appropriate
| research. Send grant money to Jose, care of Usenet.
