Any one else here in aviation?

What do you do in the airline biz?

You've gotta give these Russians credit, their engineering skills are unmatched. And if all the circumstances are playing for them and they even get the money to assemble what they've crunched out, you get these wonderful pieces. I'd not like to get into a dogfight with this gem baby here.
I'm Impressed!! I don't think I've ever seen a plane that stable at that low of a velocity pull out of a flat spin so easily----and I'm pressed with the engineering behind the variable canards. I've wondered for years why the US has never put canards on any of our fighters----but then, I'm not in the military, either, so I guess they have their reasons...:biggrin1:

There has been an experimental version, built by Grumman, as Type X-29, during the 80s. I have only read about it in some specific magazines, but the tests were very successful, yet the program was so costly that it was killed after the cold war. If I remember correctly, the knack was about transferring the forces, and setting the position of the controls in situations of high angles of attack, which required a lot of electronic correcting in flight. Same with variable canards, it takes a lot of computating to match their stall characteristics with the main wings, and the sizing was problematic too. They are positioned closer to the center of gravity, thus requiring larger forces than conventional elevators, thus requiring more surface, etc... and again something brilliant that never passed the experimental status. Unlike the Russians, we had to account for our expenses.

I met a couple of Flankers over the Gulf of Sidra once. They are fast and highly manouverable - for about 30 minutes. -I assume of them one got home. We, (and our F-14D) got home without a scratch.

Claire, you are wicked cool!
