Barrel roll

[FNG]

I don't want to start a fight, but has anyone here tried a barrel roll in their RV-9?

It feels like it would be easy..

[ed. The RV-9/A is not approved for aerobatics, and a lot of FAA I.P. addresses visit this site daily. If you want to admit online to doing acro in an RV-9/A, let me know how that works out ;^). v/r,dr]

Here’s a thought.... hop in your RV-9, fly to Santa Paula, (KSZP) rent a Decathlon and instructor at CP Aviation and you can do all the barrel rolls you like. And it’ll be fun, and safe. I promise!

You can roll just about any airplane.

You could even put a -9 in phase 1, test each manuver you want to do, and then sign it off to do aerobatics just as readily as any other experimental to make it technically legal.

That doesn't make it a good idea in an airplane that isn't designed for it. A number of folks have pulled apart non-aerobatic airplanes doing acro.

I recently finished reading "Growing up Boeing", about some of the Boeing test pilots in the post-war era and the early development of the 707, 727, 747, 737, and 757.

No one publicly admits it, but the author (the daughter of a former Boeing Chief Test Pilot) pretty clearly documents that everything up to, but probably not including, the 787 has been barrel rolled.

If they can roll a 747, I'm guessing you can roll pretty much anything.

True, and one of the best ways to determine if you have the skill and experience to safely do it is whether or not you wonder about it in the first place.

Search Boeing 707 barrel roll for video. Tex Johnson in the prototype 707 which at that time was called the dash 80. While it was generally referred to as a barrel roll it was actually a aileron roll.

At least one person did: https://www.youtube.com/watch?v=8eTIxg6pOBY

And before the pile-on starts, it's not me and I don't recommend it. So the answer to your question is "Yes, but don't".

Pardon my ignorance here, but what?s the big deal about a barrel roll? Essentially, it?s a 1g maneuver which makes it pretty benign. While I would agree that you wouldn?t want to go out and do snap rolls and outside loops in an RV-9, what?s the danger of doing something as docile as a barrel roll?

I'd suggest you are correct, there is nothing wrong with the barrel roll in and of itself. But what about when it doesn't turn out as planned, as often happens (nose isn't high enough, pulled to hard going over the top, etc) - we all know how quickly these machines wind up and all of a sudden you're well north of 1G...if you're wanting to do aeros, I'd suggest doing them in an aircraft that's designed for it

If we accept the traditional acro definitions, a barrel roll is a combined looping and rolling maneuver. You can't do a barrel roll at 1G. You are thinking of the simple aileron roll where you pitch up a little, neutralize the elevator and just push the stick over, which can be done at 1G thru the roll.
