Accelerated stall: same us above, but there must be >1G. In such condition, you need higher AoA than in 1G flight, because lift is countered not only by weight, but by sum of weight and centrifugal force.

Dynamic stall: you increase AoA past a critical value very quickly, vortex is created at leading edge, lift increases, then vortex detaches and you experience rapid loss of lift and sometimes even a high nose-down pitching.

I think, important things about dynamic stall is: amplitude and rate of AoA change, and increase of lift before the stall.

Thanks for the feedback Zaltys..

Looking at your definitions of Accelerated and Dynamic..

Your dynamic def reads just like the link I posted.. Except there is no mention of how the variations in stall are due to the variations atmosphere.. From the link I posted they point out how the stall can vary due to the variation in wind (atmosphere). Other than that the two defs are very interchangeable.

One other thing, you stated you 'need higher AoA than in 1G flight'.. IMHO you should re-word that to read 'during a constant altitude banked turn the AoA will have to be higher than it would be during level flight (1g) at the same speed'.. That example is a little easier for most to visualize. It is also important to note the critical AoA at which the stall occurs is the same for all three cases.

There is good news. A list of questions has been transferred to Ilya. The answers will be published this Friday. You will find a lot of positive things. And finally you will get so interested in all the information about how the CloD will be merged with the sequels. Wait)

Nice, I predict it will keep the mob appeased for no less than one week and no more than two point three seven four weeks depending on how Mars and Jupiter are conjuncted (is that even a word?) at the time of a virgin being sacrificed in little whinging.

I disagree, there will be an unconstructive criticism within three pages of Fridays post.

That's the problem with you armchair critics, no idea of the reality of the situation

I disagree, there will be an unconstructive criticism before fridays post!

Just give them a few min and they will be dissin BlackSix post before you kno..

Oh wait never mind I see some allready have!

Like clock work these guys!

Sorry to correct you but there are no virgins in Little Whinging. I know, I've been there.

Damn. I have a day off work Friday with a lot to do and now it will be wasted hanging around the computer.
