Some very wild post stall maneuvers from the SU-35 at MAKS 2017. [ame]http://www.youtube.com/watch?v=eTyT0OfPq1k[/ame]
I've always loved watching the Sukhoi demos...they make some of my favorite jets. The old Su-47 looks amazing with its forward swept wing design, but the 35/37 are bosses. The 5:30 and 6:30 marks in the video are crazy.
I have to agree they are not real useful in a dogfight as you become a bit of a sitting duck but definitely spectacular to watch.
At least on the Su-27/30, they had various circuit breakers pulled to make the jets do some of those maneuvers. Not sure about the ones with canards.
Very impressive. I remember a few years ago being amazed by a Russian maneuver called the "cobra". This blows that away.
Looks like they gave up on the canards after the Su-30/33. The 3D nozzles on that one really help with low speed maneuvering. The F-22A only has 2D nozzles.
Not to be picky here but I always felt that the nozzles on the F-22 are 1D since they can only move the aircraft in Pitch. X axis. With the Su they can change pitch and yaw with the nozzles 2D. X and Y axis. A true 3D nozzle allow the thrust to change directions making the aircraft fly forwards as well as backwards. True full X, Y and Z axis like a helicopter. Or perhaps I am just overthinking it
1D is fixed, 2D is one degree of freedom, 3D is two degrees of freedom. Helicopters are a bunch of parts all flying in close formation, so not sure how they fit into that thought process. You can have a 2D nozzle that can provide for backwards thrust. Just has to have enough travel without hitting something.
For some reason, US manufacturers of fighters do not like thrust reversers on them, since they introduce weight and complexity. The Tornado has them, but they are hooked to the squat switches, so not too handy in a dogfight. Seems like the C-130 props can be reversed in the air.
It's the C-17 that can reverse in flight for a high rate descent. There are some videos on YouTube that show 15-20k VVI descents.
The reversers on the C-17 are spectacular to say the least watching that whale come in stop on a dime then back up the runway is jaw dropping the first time you see it.
The only folks I have known who have put the props into reverse in a C-130 while in flight very much regretted that mistake. Several crew members were injured and the aircraft required a lot of inspections and some repairs. The C-130 can do some amazing things but going into reverse in flight isn't one of those. If you want a penetration descent in the 130 you really just pull back the power. The H models were a little better at high rates of descent due to the greater drag when the props were at flight idle but the J model can do pretty well. A friend discovered recently that the VVI maxes out at 9,999 which isn't too shabby.
