One of the reason the stabs offer more authority for the Raptor is the fact that they are pushed back. to requote the LM enginneer: take a look to the position of the stabs on a Flanker and on a Raptor.

That’s the same with F 18 vs F 16. Although the Viper has a better over-all aero design, the stabs do not extend over the end of the engine nozzles. OTOH the Hornet has the same stabs pushed back. The result: a much better dynamics in vertical plan (AoA, pitch rate)

The Su-27 is not less capable in agility niether less advanced than the F-22, the F-22 does all those maneovres only thanks to Thrust vectoring, that is the sad reality, the F-22 tail planes are not pushed back more than those of the Flanker, the Flanker has it vertical fins closer to central geometrical axis than the F-15 to cite an example, and as the F-18 the vertical fins are located farther away from the jet nozzles.

The reason why the Su-27 tailplanes look closer to the center is just perspective, in few wrords the jet pipes in the F-22 are less protuding, but the tailplanes either horizontan and vertical have almost the same relative position with respect each other in the Flanker as in the F-22

The Idea the F-22 is better designed than the Su-27 does not hold any truth at all, the F-22 is only better because it has stealth but undoutedly as the Su-27 both designs need thrust vectoring for some maneuvres because without them there is no way both aircraft will control the post stall loss of lift and inertia.

In fact if you read what the Russian experts say, they will tell you that the F-22 offers more drag than a slim cross esction of a Su-27, Why? well simple the F-22 has a large frontal cross section

Цитата:
Но опять таки:
1)стремление достичь сверхзвуковой крейсерской скорости полета неизбежно повлекло за собой необходимость значительного снижения сопротивления за счет размещения подвесного вооружения во внутренних отсеках F-22A, но сие привело к увеличению суммарной площади миделевого сечения самолета по сравнению с вариантом, когда ракеты и бомбы располагаются под крылом на пилонах. В результате из-за увеличения миделя волновая составляющая возросла.
– Я готов доказать, что эти “эксперты” гроша ломаного не стоят, вот сечения Су-27 (c подвесками) и F-22, сравнивайте

Quotation:
But again after all:
1) the tendency to reach supersonic cruising flight speed unavoidably involved the need for significant reduction in the resistance due to the arrangement of suspension armament in the internal sections F -22a, but this it led to an increase in the summary area of maximum cross section of aircraft in comparison with the version, when rockets and bombs are located under the wing on the pylons. As a result because of an increase in the midship section wave component grew.
– I am ready to prove, that these “experts” of the half copeck coin of broken line do not cost, here are sections Su-27 (c by suspensions) and F -22, compare

That the YF-17 routinely performed a maneuver which today would immediately be recognized as the cobra is not a “belief,” it is a fact. The Northrop team referred to it as the “hang and look.” Your pompous and dismissive attitude is sadly typical of those who just cannot comprehend a reality in which their beloved Flanker is not the be-all and end-all of aerodynamic achievement. There is documentation online if you’d care to bother yourself to actually consider an opposing viewpoint (a shockingly new and alien concept for some people) at:

The Su-27 was the first aircraft to be able to fly at 120 deg AoA, that is the reason they say Pugachev`s cobra, however the F-18 flies a similar cobra but the AoA is not as high as in the case of the Su-27, the Su-27 can achieve a much higher AoA, see this video:

http://video.google.com/videoplay?docid=865641049242086222&q=F%2FA-18+Hornet&hl=en

You can see an F-18 doing a semi Cobra but you like it or not the Pugachev`s Cobra was first performed by the Russians as we know it with an AoA of 120 deg

Thanx for the reply flogger. So from what I can decipher, essentially Kulbit = Frolov Chakra ??

PS: Do you have the full F-16 MATV video?

yes it is, Frolov Chakra and Kulbit are the same manoeuvre

According to the site where you got those diagrams the Kulbit definition is:

I think the Raptor pretty much did every step described in this quote

Did you see they say altitude gain is minimal see the F-22 gains a lot of altitude, in fact the kulbits is a somersault gaining little altitude

Altitude gain is minimal, and airspeed drops quickly as AOA reaches 90 deg.; the aircraft is still moving horizontally.

ANother fact is the F-22 slows down a lot almost like in a tail slide while the SU-37 makes the kulbit very fast

That’s was most definately not the Bell shown in the video. The Raptor does the Bell in another video I posted about the F-22 about high-alpha testing.

In the video I posted at the beginning the F-22 clearing pitches into a Cobra, keeps pitching over the top, gains altitude while basically flying backwards, then uses thrust vectoring to bring the nose around. That is a Kulbit no matter what you say. I think most everyone in this thread would agree with me.

you do not call a tail slide a kulbiit buddy, the Su-37 can do two somersaults and what the F-22 does in tha video is basicly gain altitude slow down and spin after it finishes the tail slide in fact all the time in tha video you see tail slides.

see two somersaults that is a real kulbit, kulbit in russian means circle
