Barrel Roll fail

[ACG_Orb]

Can anyone provide advice on barrel rolls? 

 

I've been trying for hours but the best i can achieve is a sort of flattened barrel (see pic).  I've followed guides by picking a point on the horizon between my nose and wingtip, pulling up then back right to angle a 45 degree climb.  While committing to the roll I keep the horizon point central in my view.  However, I always seem to flatten out a good distance to the side of my original heading (I should arrive on the same line).

 

 

I think i'm spending too long at the top of the roll than the bottom - but if i speed up my initial pull i black out.

 

Does anyone know what my fundamental mistake is and how to fix it?

 

Cheers!

It would help if you could provide a track, a .acmi tacview file, or a video.

Hello ACG

 

You are not supposed  to "arrive" at the same line. That is just not possible in a Barrel roll. In the Barrel roll you basically combine a loop and a roll. On the top of the maneuver the plane is on its back and the nose pointing either left or right from the original heading. So going back to the same original line is not possible, because the plane is now moving away from it. And you will do so for the remaining part of the maneuver until you "arrive" at the original heading.

 

If this does not make sence then I have made a videotutorial that you are welcome to Watch. You can see how the maneuver is performed from the front view in the top right corner of the videolink.

 

Best regards

Ahh... looking at this then i'm not actually far off?  I was referencing really old WWII training vid as as a guide which i'm sure said you need to finish on the same line.  I probably misinterpreted it.

 

Cheers for the advice!

I would say you are right on the money with what you have shown ?

 

If you are using the Barrel roll as an aerobatic figure and not a combat maneuver then it is important, that the rate of roll remains constant throughout the maneuver. This requires small aileron adjusments during the manuever as the plane first losses speed and then gains speed. It is also important to release some of the backpressure on the stick as the plane comes through the top of the manuever. This will make the line the plane makes more circular when viewed from the flightdirection.

 

Thank you for watching my video ?

Thanks for this!  

 

Yes, your videos are great - also helped me nail a hammerhead 

 

Subbed in case you create any more.

Took me a long time to learn that Hammerhead, so it is great that you are already nailing it ?

 

All my videos are listed in this thread: 

 

Bf-109 E-7 Tutorials and aerobatic maneuvers

 

As for new tutorials on aerobatics I hope to get some more spare time to create some, but I have been swamped in Work and Family.

Most of my spare time right now goes into research on how the Luftwaffe trained their pilots before and during the war. This will hopefully some day lead to some new tutorials on how to perform the basic training for new pilots including aerobatics, which by the way translates to "Kunstflug" in german.

 

Thanks for the Sub ?

 

Best regards

Hi Hernrik.  I love your videos and have a query on Hammerhead.  I am really struggling with this in a FW190A.  Just keep rolling on my back or spinning anti-clockwise (despite full right aileron).  Any clues on what I might be doing wrong and why different to 109?  Gyro precession effects maybe?  My end game is to be able to do a good Hammerhead in 190A3 and then learn the "sliceback" explained by Kylander in "In Pursuit" book, which looks very much like a Hammerhead.  Thanks
