Ye cannae change the laws o' physics

Unless you're flying a model 'plane



Pretty fucking amazing, IMHO.

The amazing thing was near the end when he dove towards the ground... and
then hit REVERSE!

 

Just a reversible leccy motor, Shirley?

 

I'm not sure propellers work like that...

 

Was it? I assumed it was just a stepper motor, never thought it might
be variable pitch.

 

Nah, can't be a stepper, too slow n heavy.

It apparently is a variable prop, like this:

Amazing.

 

Its done by strings from the ceiling

 

Pah

 

Blimey. That's what happens when you don't pay attention. Now I know
I want one, I just have to figure out what to do with it!

Christ, but you don't half talk some bollocks... I was about to say
"sometimes", but then I realised.

I know I'm going to regret asking this but...

how does a fixed-wing plane fly upside down? AIUI the shape of the wing
reduces pressure on the upper surface and increases it below, creating
lift. When the wrong way up why doesn't it create 'drop'?

 

'Cause the lower surface replaces the upper surface after the
transition on a temporary, "lend us a tenner" sort of way, and does
the relevant sucking.

 

It's all to do with the angle of the wing to the direction of travel.
When in a normal orientation the wing is sloped up at the front so as
the fuselage moves straight forward the wing presents a given angle of
attack to the wind; when flying upside down the fuselage is angled
even more up wrt the direction of travle, so the wing's angle of
attack is about the same. Sure, they're designed to work best in their
normal configuration, but the shape of the upper and lower sides of a
wing aren't _that_ different.

 

I imagine the plane points slightly upwards, so the force exerted by
the propeller has a vertical component.

 

Symmetrical aerofoil or simply make up for poorer perfomance inverted
by increasing the angle of attack.

 

Watch at the very beginning, before take off when he does final checks,
the whole wing moves as well as the flaps

 

Oh right. Yeah, if you're talking about toy planes, then sure. I was
assuming the question was about real ones.

 

I've seen a live display of a SUKHOI and the thought crossed my mind:
To stop the pilot blacking out his G suit must have squeezed his balls
up around his ear lobes.
