You working on the over-performance of in-game FM or something? just sharing links?
For now I’m just sharing links.
Quote:-The aerodynamic advantages derived from the close coupled canard configuration, foremost its good vortex flow stability up to high angles of attack (AOA), that can be translated into a very high instantaneous turn rate,-
Delta canard’s inherent good aerodynamics are:
· Stable detached leading edge vortex flow, high maximum lift coefficient.
· Positive trim lift on all lifting surfaces.
· Floating canard offers stable aircraft if EFCS fails.
· Good field performance (take off and landing), enhanced by special aerodynamic breaking mode.
· Battle damage tolerance good, “overlapping” control surfaces.
· Potential for future adaptations, like steep approach, fuselage aiming.
· Low buffeting levels made even better with leading edge flaps.
Spin recovery known to be acceptable for close coupled delta canard (not necessarily so for a long coupled canard configuration):
One of the disadvantages is that the mid-canard does not come out of a tailspin
Quote:-Rebourg said that to date, they have not been able to depart the aircraft into a spin».
DAVID M. NORTH/ISTRES, FRANCE quoting Philippe Rebourg, «deputy chief test pilot for military aircraft at Dassault.-
The Swedes, accustomed as they are to high technology, are astonished by the performance that is possible on the MiG-29. That the Fulcrum, with its two RD-33 engines each producing 81.3kN of thrust with afterburning, should have considerably more power available than the Gripen is no surprise. The JAS 39 is after all powered by a single RM12 turbofan developed by Volvo from the General Electric F404 turbine and delivering 80.5kN of thrust with afterburning. ”But they have been really surprised by what we can achieve despite the MiG’s outdated avionics”, says Squadron Leader Treinies.

Well there we go, around 16°, case closed lol
That’s the Gripen E, with improved engines I’m guessing, because that was all without full afterburner.
It was all at full afterburner otherwise the turn would have been 30 seconds
Wow, eyes like a hawk. Mind telling us what G’s he was pulling?
They never use the real/full performance for these kinds of shows, there’s also several afterburner modes and most importantly these flight-programmes are strictly planned beforehand down to each turn and also has to be approved by a higher ranking officer before performed.
It’s not just some Gripen pilot hopping in and pushing the limits
Gripen Demos commonly show the limits of what the plane can do.
And you know this for certain how
And videos can’t be used for performance any way
That’s not what the actual pilots say. You’re basing this off what?
Saab.
The only aspect they don’t show is the speed which could be used to determine bleed rate. But it’s not like they are somehow limiting what the pilot can do at an airshow as far as plane performance goes.
That’s a G-force demonstration,
I also think he was referring specifically to this demonstration when he explained this:
They literally are, for secrecy and safety purposes
The part that they obscure in the video is the speeds is because someone could generate an EM diagram based on the demonstration.
They aren’t limiting the flight performance. It goes through basically it’s entire envelope from -3G - +9G and even shows the AoA limitation towards the end.
Yeah goes through the soft-limit G-load envelope sure, we only have ‘public’ numbers in regards to AoA, not displayed in video. He rarely even turn on the afterburner, it’s pretty clear just watching this it’s miles ahead of anything like an M2K drag-wise
So we are just supposed to assume there is some secret 12G+ envelope and some kind of AoA limit that exceeds the published limit?
He actually turns on the afterburner for some of the turns. You can see the throttle settings for good portions of the video.
