So, was Sergey Ivanovich responsible for the design of the SU-22 and the F/A-18???

I think he was just venting his frustration on Boeing’s inability to solve relatively simple problems with spanwise airflow on swept wings, something what Soviets mastered in late 40ies with help of trivial wing fences. It seems that those small wing fences on the outboard wing section are doing their job better than a sawtooth (add drag as well) added to the LE, especially to the LE of moderate wing sweep(20 deg). Their effect is to form counter-rotating vortices outboard of the fence which prevent and delay flow separation in the tip region, resulting even to higher lift as well.
Anyway, does a nonmetalic structure increases overall aircraft RCS?

P.S.This will not make you feel better about wing fences, however the most “fenced” wing among early soviet designs was the Mig-17 wing. Three full-chord wing fences on each wing and still the aircraft was achieving subsonic L/D ratio of 14.6 and frontal RCS of 0.7 square meters. I doubt that Hornet, Super Hornet or future Hyper Hornet will ever reach those figures. 😎

So why not say “Rafale, Typhoon, and F-22A”? :diablo:

The rest(overhyped Typhoon, Raptor, …) was not worth mentioning. :diablo:

Give me one firm source on Internal fuel , none seem to agree with each other .

Hmm, how about to ask technicians on the Raptor internal fuel, iirc you know many of them.

Since the top speed of F-15 has been discussed here, does anyone know what is the test flight profile which has to be carried out after an routine engine change. Can someone access these information?
thanks

Eh, my mistake. I assumed (yeah, I know) that “latest” meant it wasn’t older then I am 😮 😮

BTW- Who’s Rich Johnson??? 😉

Do not worry, nobody is perfect:)

some differences between the North Vietnamese Sa-75 Dvina and S-75 Volkhov.

Sa-75 Dvina Fan Song radar

Let’s see, Kelly Johnson, Ben Rich, numerous Blackbird pilots. But then I guess you’re smarter than they are and were present at every Blackbird overflight flown eh? :rolleyes:

Here’s a page from a previously classified document. Looks like the Blackbird is in an out of the danger zone of an SA-2 in about six seconds. Yep, REAL easy target. Must be why they were able to shoot so many down.

Tell me what SA-2 type is this diagram related to? The Sa-75, Sa-75M, S-75, S-75M, S-75M2, S-75M3 or the latest S-75M4? Must be for all, bcs they would not tell you BS in their propaganda books, right?.:rolleyes:
Using your jargon, all your country men must be smarter than dozen of former PVO operators I talked recently who had “on screen” experience with the Blackbird and surely your classified document is smarter than dozen of classified documents I have seen in the past on soviet SAMs systems. Looking at the diagram you posted I have no doubt for what SA-2 type it is for, but pointless to tell you.

LOL! Must be why they shot so many down over Vietnam. The majority of those “thousand SAMs that missed” were probably Guidlines so it apparently wasn’t as easy of a target as the S-75 operators thought. :diablo:

LOL, thousand SAMs fired at SR-71 that missed and what idiot told you that? What were they counting anyway, real missile launches or just FAN SONG lock-on signals? 😀

Now seriously Scott, regarding North Vietnam Blackird overflights you seem to fail distinguish between the S-75M Volkhov(SA-2 Guideline) and the SA-75M Dvina (SA-2 Guideline ;)) of the NVA. Both are similar in design and general appearence, but with different performance. The North Vietnamese Army forces were equipped with the SA-75M Dvina and the V-750V missile ONLY which was able to destroy approaching targets moving at 560 m/s and 420m/s when chasing. The S-75 Volkhov missiles 20DP, 20DSU or the 5Ja23 had the approach target speed up to 1100m/s. Those stats and others you can easily read in SA-2 manuals.
Moreover, in the document called “Air defence combat employment of the NVA”, a three-hundred page thick and once top-secret teaching air for Air Defenses of former Warsaw pact, are described experiences and combat tactics of the Vietnam People’s Air Defense against the US airforce since1965. A very detailed document describing also US airforce combat tactics utilizing jammer fitted aircrafts(RB-66, EC-121K, RF-4C,..etc ) against early warning Spoon rest radars and SA-2 SAM sites, tactics used to fight Navy ARM Shrike missiles,…etc. It also touches the reconnaissance flights over Vietnam, where the SR-71 appeared for the first time at the end of the year 1967. They acknowledged to fire missiles which failed to hit the Blackbird bcs of several obvious reasons. The first one is mentioned above when you look at the SA-75 missile performance, the second one when the Spoon Rest radar detected incoming SR-71, it took several minutes to route the signal to the best located SAM site. Thus, almost always the SA-75 missiles were chasing the Blackird with no chance.

P.S. The SA-2 sites used in WP countries were a bit different to those Vietnamese. Please reveil me how many times we fired missiles at Sr-71? :rolleyes:
