wrote: My take on this is that an airplane in a 1G roll would follow the same path as any other object. Imagine your in space. A 1G roll would be a perfect circle with a constant 1G acceleration. Now bring that path into the Earth's gravity well. Now the 1G roll is all messed up by the Earth's 1G. How can we fix that? Just like the Vomit Comet does, by accelerating down at 9.8m/s^2. Superimpose a roll on top of a parabolic descent and you have the path of a theoretical airplane in a 1G roll. I don't think there is a plane that could actually perform this maneuver in reality. Obviously, the quicker you can roll, the easier it would be, but essentially it would be impossible to complete a constant 1G roll back to S&L. You would have to end up in a nose-down attitude in order to maintain 1G while inverted. The greater your roll rate, the less time you'll need to maintain positive G while inverted, and hence the nose won't need to drop as far. The closest you're going to get to this is a simple aileron roll where you start nose high... but then you've pulled more than 1G to get the nose in to that position! -- PERCUSSIVE MAINTENANCE: The fine art of whacking the cr*p out of an electronic device to get it to work again. |
