My point is:
_ Most fighters are put in spin recovery / departure test, but able to recover from a spin, highly spin resistant doesn’t mean they have control authority to ultilize post stall maneuver in combat. Because PSM for combat also require high level of accuracy for the pitch/ yaw rate, as well as the ability to start / stop quickly
_ thincankiller claimed the pedal/helicopter turn is not a post stall maneuver, and Rafale had done the same thing, so the homework is simple: where is the video?
well, not “most fighters” but “all fighters” have to pass those tests, as in combat, you never know what the pilot will have to do and if he won’t find himself in a spin at a moment.. so these tests are mandatory to validate the behavior of the new aircraft under such circumstances… as I pointed out above, the chief test pilot explained that they were unable to get the Rafale into a spin no matter what they did to it, and to be able to perform the spin test, they had to deactivate most if not all protections of the FCS. Once they’ve done it, they validated it had positive behavior and was safe.. and then went on… as they’ve concluded that they don’t need PSM, the FCS was programmed that way.. so you won’t ever see a Rafale perform such manoeuvers, simply because the FCS will keep it under a flight rules it was programmed to maintain
and you won’t find a video of Rafale spin tests, if anything, because the french didn’t film all the flight tests and those they have are most certainly kept confidential.. which is the french policy dating from decades (an example of that policy was seen about 15 years ago when some developers were working on Falklands air war.. they could get all the information needed for the Harrier modelling, but when it came to the MIrage III (we were in the early 2000’s, remember), they asked to french sources but couldn’t get any useful information because it was still classified (in France, the Mirage III had been retired some 20 years ago at the time).. they had to work with Argentina
Yet you can’t find a single video of Rafale and Gripen perform a post stall maneuver. What a coincident
on the other hand, if their FCS is programmed to remain capped at 28-29°, it’s not supposed to get there in the first place, no? There was an interview of the Rafale chief test pilot Yves Kerhervé who explained that, during development, for spin testing they had to disable a number of fcs features to have it in a pretty much “direct mode” (no automatic recovery of anything of the sorts) as the aircraft simply wouldn’t depart into a spin regardless of what the pilot did, and what’s more, even when they finally managed to get it into a spin, all they had to do was to release stick and rudder, and the aircraft would recover itself aerodynamically (with no input either from the pilot nor the fcs – as the fcs was in that “direct mode”)
So, basically, if they have made a choice not to go into post stall manoeuvering and programmed the FCS that way, how would you see the Rafale doing any post stall manoeuvers?
@ garryA, about your last pic.. all the opposing aircraft has to do is extend in a high yoyo manoeuver and close in for a gun kill from above… the X-31A falling like a leaf would just be a nice target in such a scenario.. looks nice on paper, but you need an opponent that coooperates with you to get such a kill 😉
I should point out that this isn’t really impressive for a g spike. An F-15 pulled 12g in a split S during Desert Storm.
thing is, the F-15 has no hardware limiter for acceleration.. if you pull the stick you get the G’s.. it can become harder mechanically above certain amount of G’s but if you have the strength, you can pull more… the FBW aircraft, you can pull the stick as strongly as you wish, up to ripping it out of its base, but the system won’t ever give you more G’s than what it’s programmed for..
What do you mean by “rough field capability” landing a MiG-21 on a farmer’s field? Good look to that. As it happen much of NATO air power could disperse too if they wanted too – I just don’t think they were really bothered about it at the time – dispersal airfields can be nuked too, you know.
who speaks about dispersal fields? If serbs managed to put their migs in safety and loose some almost exclusively in the air (as they kept operating them, whenever possible despite something like 300 combat aircraft massed by NATO in the area), chances are russians would be able to do it as well, espacially when not being outnumbered nearly as bad… I seriously doubt that serbs have some kind of magic specific to their air force. Again, I’m not saying “look what serbs would do in such case”.. I say “look at what they did”…
except that most russian fighters had rough field capability.. if it went to escalate, chances are they’d be dispersed to avoid being destroyed on the ground.. just look at a small country like serbia, bombed for several months by NATO and who only had half a dozen Mig 29s at the begining of the war… and they lost pretty much none (if any) on the ground, not to speak about Mig 21s which also mostly survived the bombing campaign
like anybody else, no fighter in the 1980’s (and even today) will sustain 9G when fully laden with ground ordnance.. you may get 9G in instant turn when you have depleted a good amount of your fuel and carry only air to air armament, but that’s about it
they developed extra long range missiles, R-33 for the Mig-31 at first and then a derivative R-37, to end up with the KS-172 in the 1990’s
well, “poorly written” as he may have misheard 36 for 3 to 6, what did he hear to get 24 and then 20? 2 to 4 and 2 to 0? You speak about “biases”, but don’t question your own bias, obviously.
I came across that article and that sounded crazy, but explanations that the author didn’t know what happened sound a little funny to me.. or do you imply that defense aerospace is a site dedicated to bashing the F-35 (among probably others?
er, something crazy written here, 36 hours to remove an engine???

Happy New Year everybody, btw 😀
when complaint is made for internal political reasons, legal reality matters little.. the idea is to make noise and bring doubt in people’s minds
the past is the past, I reminded what the french have stated just weeks ago… if they want to be taken seriously, they need also to be consistant with what they say, and if they do, Belgium will only watch the project from the outside (eventually, they’ll be in position to buy it off the shelf if they want, but won’t benefit from workshare or tech transfers).. of course, the french can also say they didn’t really mean it, but then, what eventually remained of their credibility goes down the toilet as well 😉
The french have proposed to Belgium to join the NGF program as partners if they buy the Rafale… they also said that if Belgium choose otherwise, they can say goodbye to any partnership in NGF, something that some guys in Belgium (foreign relationships advisors or something like that) didn’t like… not that the french care whatsoever what they may say, especially now that Belgium seems to have chosen the F-35.. It seems that belgians better make sure they get plenty of work share for the F-35 as the french may very well do what they said and let belgians completely out of the program
Qatar is having some issues financing a Typhoon purchase, so I wonder what the means for the Eagle and Rafale orders?
not necessarily much… with loan costs so low as today, they may simply find more interesting to borrow some cash for almost nothing and let their own cash generate profit (higher than what the loan cost them)
