ATR 42 'Barrel' Roll

[Anthony]

Hey Guys

This was on Airliners.Net today.


This was the CEO of Climber Air, a Danish airline, who was flying the aircraft.
He executed a "controlled roll" at about 1G I think.

It's a little bit like the Cathay Pacific low-level fly-by from a while ago.
Dangerous and a bit stupid, but very cool all the same.

Actually, this is one good reason why you become the CEO of an airline.

Cheers
Anthony

Awesome!

So now I know an ATR can do a roll too, so far that's a 707, Vulcan and now this on the list!

[Alfashark]

Go hunting around on youtube for some Bob Hoover clips...

Any man who rolls an Aero-Commander while various Airforce officials are having a cuppa poured in the cabin has got talent... especially when they made him do it again since they didn't believe that it had just happened

Also used to perform a low energy aero routine in the Aero-Commander at airshows - Dead stick of course, just to make it really interesting

I think you should have a list of those which cant. I cant think of (off the top of my head) of any aeroplane which could technically not (and all you airliner geeks dont even think about mentioning the word "Airbus" because control laws can be turned off, some how)

The dornier has a good rate (actually really good) of roll in the ailerons and apparently does good aileron rolls (not that I've tried) actually if you type in dornier 228 into youtube there is one somewhere down the page entitled dornier aerobatics or somethin like that where tis at an airshow (in iceland I think) and does heaps of rolls an stuff, even with one engine shut down which is pretty neat.
There also a vid of an aileron roll in the beech 1900 in africa somewhere and another (same plane) doin a bob hoover (rollin whilst poorin tea) in the 1900

Not one to try everyday - BUT - Provided the pilot knows what they are doing, has plenty of altitude and can positive G and airspeed within nomal limits there is no reason this can't be done safely on almost any fixed wing aircraft. As others have said - Bob Hoover was the master of this. The prototype 707 was rolled by the famous Boeing test pilot Tex Johnson - google his name to see the clips.

Other large aircraft that I know have been barrel rolled:
Concorde
P3 Orion - Austrailian Airforce - inadvertently over did a wing over an had to continue!!
Andover - RNZAF
747 - I believe

There's a good video on Youtube of a B1900 doing a roll in Africa somewhere, makes it look easy too!

[Naki]

A 747!!! - yes seen the 1900 roll - the Dutch Air Force use to throw their F-27s around at air shows - they must of being rolled a few times.

In one of Bryan Coxe's books (the RNZAF Corsair pliot and civilian instructor after the war) says he rolled a Cessna 402 (one of his favourtie aircraft) and a Twin Comanche.

[Peppermint]

Heh, that 1900 in South Africa was a good vid, saw it a while ago now, they started flying below tree height up a river..is that the one? A 747 and Concorde doing a roll?! This I have to see!

Yeah, that's the one I was thinking of.

I recall a video of a RNAF 27 being looped ! , and to see the C27 Spartan at Avalon last year , rolled and do a vertical climb and stall !

Hey Guys

Look at this article ATR Story
Apparently it may have been damaged
Although it was cool it was dangerous. ATRs are not surpose to do barrel roles.

You'd be amazed at what can be done or has been done in various a/c with smooth control inputs and a knowledge of the potential outcomes...

The prototype 747 nosed its way through the sound barrier during flight testing...

I've seen an old 35mm film of a C185 performing a barrel roll (taken from inside... apart from the pilot and the deer carcass which was strapped/tied down, the hunters were just sitting on their packs on the floor. Nothing moved, apart from the horizon).

A Transavia Airtruck, looping and trying to chase the tow-rope on descent from a glider launch.

Personally rolled a glider, (twice) Not entirely pleasant, the roll rate is glacial at the top of the entry pitch-up and the things tend to "slide" wingtip first into the inverted phase - really makes you wish you'd pulled the harness tighter when pushing back up the other side.

Good and interesting find Daniel.
You're right, ATRs probably aren't really meant to be barrel rolled.

I was under the impression that done correctly (stress that small fact) it is a 1g manouevre and any aircraft can do it without damage.
Following the link that Daniel gave, I came across a reference to a Nimrod airshow crash in Toronto in 1995.
It was sort of implied that it barrel-rolled into the ocean.
Anyone know what really caused the crash?

[Alfashark]

The Nimrod display aircraft and crew had deployed to Canada on 23 August 1995 for displays at Canadian Forces Base Shearwater and the Canadian International Air Show (CIAS) at Toronto.
In excellent weather, with a light on-shore wind, the aircraft took off on time for its display. Upon completion of the safety checks, it ran in for the standard Nimrod display sequence which features two orbits and two dumb-bell turns. The latter manoeuvres each involved a turn away from the display line, a climb to not above 1,000 ft, followed by a turn in the opposite direction and descent, to fly back parallel with the display line. Having completed the two orbits, the first dumb-bell turn was completed uneventfully. After a slow flypast with undercarriage down, the aircraft entered its final manoeuvre, the second dumb-bell turn. It was seen to turn away approximately 75° to starboard under full power before the flaps were retracted to 20° and the undercarriage raised. The nose was then pitched up into a climbing attitude of 24°. As the aircraft passed 950 ft, engine power was reduced to almost flight idle, following which the speed reduced rapidly to 122 knots, below the 150 knots recommended and taught for that stage of the display. The aircraft was rolled to 70° of port bank, shortly afterwards reducing to 45°, and the nose lowered to 5° below the horizon. During this turn the airspeed increased slightly and the G-loading increased to 1 .6G. However, the combination of the low airspeed and the G-loading led the aircraft to stall, whereupon the port wing dropped to 85° of bank and the nose dropped to 18° below the horizon. Full starboard aileron and full engine power were applied in an attempt to recover the aircraft but, by this stage, there was insufficient height to recover and the aircraft hit the water.

Classic case of the incipient spin.

Ah thank you...they also leak fuel and blow up over Afghanistan...probably time the Comet legend was buried.

Its British... It was designed to leak!

Oil, fuel, rain... Just think - if Lucas made firearms, world wars wouldn't start either

Some of the younger ones here or the non petrolheads probably wont get that one.

I get ya! Dad's Leyland leaks oil... His mate spent about $300,000 restoring every nut and bolt on his awesome Leyland Hippo- still leaks

[towerguy]

stick to the correct speed and G loading and any aircraft can be barrel rolled - its really just a continuous climbing turn. I did read a pilot report of an RAF Nimrod being barrel rolled by the flight crew to 'mess with the heads' down the back as they tried to figure out the readings on the radars etc.
