Are these two touching or not?!?!

Post by Hans.Jacobs »

hi Guys,

not sure if my eyes are fooling me, but these two Roulettes seem to be touching each other:

Image

sorry for the bad picture quality, but here's a closeup of the action. Seriously think the chaseplane is pushing down the tailplane of the inverted aircraft....

Image

The tailplane of the inverted aircraft seems to be underneath the engine cover of the chaseplane. The angle of the inverted plane is also a bit strange compared to the other one... What do you think?

best regards,
Hans.

:roll: Perhaps thats the reason why the propellor does not seem to rotate... :shock:

Sigh... think your eyes are fooling you! :?

This one looks like a real "hit"

Look carefully,
The rotor from the top-one is in front of the inverted aircraft...
The tailfin of the inverted one is in front of the top one...

i.o.w. --> it looks like a very lucky pilot (that the rotor didn't hit the inverted aircraft)

rgds, Rob

The angle of the front plane isn't an indication that he is being pushed down. Upside-down flight means extra nose down (in upside-down that's nose up :P) attitude because the wings are asymmetrical (top and bottom). They are shaped to cause optimum lift when the top side is up.

However it really looks like they're touching eachother

Definitely not touching, if you ask me. It think is is an optical illusion, cause by the traling edge of the horizontal stabilizer being perfecty lined up with a line beneath the fuselage of the other one. You can see the same line (presumably caused by the gear doors ot something) on the third plane.

Also, making contact like this would have absoluty caused a crash and this apparantly did not happen.
Answers will be questioned.....

Did you send the picture to them? Maybe they would like to respond...

i think the front plane's tail is behind the nose of the chasing plane and causes an optical illusion. IF the planes where hitting eachother, the chaseplane would definatly crash because the propellor would hit the fuselage of the front plane.

Due to the angle of the picture you might think there hitting eachother, but in reality it could be that there is a spacing of a couple of meters between them.

just my thoughts..

Cheers Brian

I still remember an air-to-air picture on the cover of AFM form 1990 where one East German Su-22 alsmost touched the fuselage of an other one with his wing.

Used a bit of shadow/highlight in photoshop to make it more clear... I'm still not convinced, cause it looks like you can see the shade of the inverted one, on the belly of the chaseplane...

Image

They could hit each other without crashing (the stabilizer is longer as a propellorblade), but as I said before, they were lucky if this happened... See the illustration below:

I also don't believe they touch but I think the guy who took the picture should know. He was there and saw what happened after he took the shot. If they seperate for a moment, regroup or even aborted the display you know enough. I can not imagine they would continu the display after they touched.

I agree with the above.. And the fact that IF there touching.. the front plane looses control of it's tail elevator and can't move op nor down.

As was to be expected, they are not. But it's a very good illusion!
I took the liberty of editing your photo. What I think Elmer and thomaster mean becomes visible with an overlay of the third planes' nose on the closest one. Some detail of the fuselage under the engine lines up exactly with the inverted one's stabilo and elevator, creating the impression the stabilo is under the nose. Actually, the inverted one is to the left (looking in flight direction) of the closest one, and a bit higher.
Nice lesson for interpretation of 'photo proof' :!:

hi Erik,

you got me convinced now, but damn, they are flying close to each other, and what a coincidence these lines are so nicely aligned...

Best regards,
Hans.
