A Helicopter 'Expert' speaks!
 

There is a poster who now calls himself Angels60, (previously ssg and trickle_451) who has suggested that Brian Abraham is an idiot but who has some very interesting theories on helicopter flight. A preview of some of his previous posts may help you form a picture, try Tech Log forum, "Is Flex/derated thrust safe" and "Would you abort after V1" followed by the rotary one, 'Which Side" http://www.pprune.org/forums/showthread.php?t=327959

Some of you may want to join in!;)

Well here I am Para...I can see your hard at work making these threads so much more educational and fullfilling...he wants to you join in because they ran out of ammo, tapped...he's mad because his cronys have turned PRN into a social gathering of misfits.....please come, I could use some intelligent discourse...

Not any more he doesn't. What an idiot :rolleyes:

;)

Angels - don't bring your 'intelligent discourse' over here - I have read your posts and we have enough fishermen on this forum already:)

A few gems :}

Classics!!! What a troll!!

Cheers

My favourite:

Now, if that isn't a 'confession', I don't know what is... :}

Ok, so he's nearly right. PIC in a helo can fly on either side, depending on aircraft, flight manual etc if single pilot, but rotor direction???

PIC in a plane doesn't have to be left seat. Can't see anything wrong with that statement actually.

What a laugh!
Senior Pilot. It's a shame he's banned, he really was great at pseudo P of F. I'm sure he could teach us a lot more. I'd like to hear his explanation of Hooke's Joint Effect and the Conservation of Angular Momentum!

Don't worry, 'Pies. He'll be back! (said in my best Arnie voice...)

pseudo P of F is my favourite subject! Used to teach it all the time. Just like I bet a lot of people teach gyroscopic precession???;)

Not really: his previous two identities were banned by other Mods, and he's already come back for another try in the past couple of hours.

Funny, he isn't: look at the fish he manages to catch even when they're warned :hmm:

Angel, If you were in the right seat and you flew fast you would roll right. If you were in the left seat you would roll right. Makes no difference where you are. Some long-line dudes fly the B212 and S61 left seat so they can see the load. No big deal. Tell me, why is the MD530 flown solo from the left?

parabellum - I get told that a lot actually, but was surprised he picked up on it so quickly.
Sorry SP I missed the warning, or am just too slow to recongnise a nod and a wink.

I think the longline dudes sit LHS (certainly in the 205 / 212) so that they can reach the collective when they are hanging out to see the load.

I am no expert having just lost my longline and bucketing virginity.

Seems to be more experts here than ever!

In order for a single pilot to operate an approved single pilot helicopter from a seat other than the designated Pilot's station (check your Flight Manual): you will have to obtain an STC to permit that function. This of course, ensures such things such as the manual release, controls, etc, are within your control.

So in order to longline from your 206/205/212, etc; you will need one more minor item than covered here.

It ain't so dumb if applied to a helicopter with a very rigid rotor.

There is an old US patent where the rotorhead is offset slightly to the side. In addition, Sikorsky's X2 Advancing Blade Concept is related to this.


Didn't the old sheriff have two 'non de plumes'? One for managing the forum and the other for personal comment.

Heeees back. tankdriver45 Is that his shoe size or IQ?

What a twit, fancy insulting all the experienced helo pilots on here with bogus physics.

On a related note, I remember reading somewhere (Wagtendonk I think) that the roll during retreating blade stall doesn't necessarily always go toward the retreating side. There's no definite reason it should as far as I can reason. Yes, there is disymmetry of lift due to advancing/retreating blades, but then gyroscopic precession takes that and turns it into a flap back.

I know gyroscopic precession isn't 'perfectly' 90 degrees so perhaps that is where the roll component is induced? I suspect there is more to it than that though. If Wagtendonk is correct then perhaps the shape of the helicopter's fuselage may have an effect on which direction it rolls?

I found his posts quite entertaining. Seldom have I heard anyone display the depths of their ignorance with such total conviction. The only downside is that there are others who might believe what he says through their own inexperience. The reasoning behind some of his statements would have made the Monty Python crowd very proud of him. He certainly sounds like he believes them himself and thats scary!

I don't actually believe he's for real. Surely, no-one's that stupid.
