Yes - just imagine - full forward cyclic, losing height quite quickly; 90 deg nose down, really going down quick now; inverted but still going down very very fast, where did that 1000 feet go? Not to mention the negative 'G' and the fact that both the engines would have been starved of oil and blown up.
I suspect that the Red Bull pilot will do it from a high rate of vertical climb or from climbing backwards flight. Good luck:ok: Back to the flip, so to speak, I believe it was GW and others who started off doing a version of the manoeuvre to get from the high hover (NI Ops) down to low level quickly, a sort of 'over the shoulder' transition. Then it was a case of well if it will do that, will it do this? and the back flip was born. |
During the Eurocopter Tiger visit to Australia in 98 or 99, the pilot flipped the Tiger in a backwards loop from the hover (kind of over the shoulder ) back to the hover from no more than 200ft ht. Very impressive.:ooh::ooh::ooh::ooh:
Then the tiger was crashed near Townsville a week or so later. :sad: |
More balls than I've got!

Back flip
It was down to Graham Waddington, who was being crewed by Ken Beveridge for the Eagles team of 1987 (although it might have been 86) I believe it started as an over the shoulder sort of thing and gradually became more and more upright until it was going straight over. Bit like being in a washing machine on the spin cycle as it goes around very quickly. Little finesse about it, cyclic 'yanked' back as far as it will go. Exciting though. Hi Diginagain, you well?

AB - have you sussed it yet - high-rate control inputs being applied at low loading in a back flip - whereas if you push cyclic forward from hover...........you do know what a cyclic is?
tongue out of cheek now |
Old beefers balls!
I am sure you and I have done those sorts of things old beefer??

Shhh Starflex - don't mention getting Pumas upside down;)

Never had the fortune of a ride in the queen of the skies with OB, would like to have though!!

The 'over the shoulder' technique assuming a good rate of rearwards climb could actually result in little more than 50' height loss - just depended on the combination of aft and lateral cyclic (and rate of application). Technically then of course it was more a 'twist' than a back flip.

"...........G.W. told me back in May that he was the first person to carry out this maneuver. He was not shooting the sh1t, but the tale came out as a follow up to the conversation we where having, we had not seen each other since we both served on the same Sqn 20 years before. john........" If he did it before 1982, then he may well have been the first. |
Helicopter loop
how do you loop a helicopter like the BO-105 redbull? at what air speed do you start pulling? colective settings during each segment?.....
|
|
You get a very good instructor to teach you in the aircraft rather than asking on here otherwise you will only try it once :(
|
|
OK now lesson #2, what are the inputs for the barrel roll? Of course for information purposes only; we all promise not to try it in a R22.
|
Lesson #3
Highly experienced helicopter aerobatic pilot doesn't get away with it this time Anyone thinking of doing any of this, give your own head a shake! |
Hi Guys
For some reason I had Mick Favinger in the frame for the flip :D |
|
First back flip...
Not that it helps the first date discussion, but in 1987 I flew the Lynx in all bar the last few displays of the season as got posted to UNFICYP and wasn't about to say no to that! However we only did the over the shoulder pull at that time, although it did get more pitchy and less roll as we got used to it...
