    Iam wondering, what was Rafale speed when the pilot pull 10G?

      airspeed is indcated on high left part or fthe hud. Thnk it was around 450 Kts, bt i should check (or you).
      i think there is a 10.5 g about 7.45'

        There's still airstream even when you're stalled. The wing or the airsream don't magically disappear - it still has an angle relative to the stream. Hence you can still measure an alpha. There's just no lift generation anymore.



        Time to get some basic flight mechanics courses.

          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.

            And a Greek 2000 13+ G on an emergency pull up. And many more.

            But these kind of occurrence usually imply a structural integrity check, especially with paylod under the wings.

              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..

                That is right...fattish looking F8F-2 is the fastest piston driven aircraft..for instance.

                  @EC 5/25 Corsair : yes, "what the hell?".... Why isn't the Pirate's AoA increase beyond 25 being plotted on your Wiki curve... Oh, wait

                    Because on a classical airfoil on a classical aircraft with no post-stall capability, there's no point in getting CL data way beyond the stall AoA.

                    Your claim that alpha as a physical quantity doesn't exist after stall remains strikingly stupid.

                      Not stupid. Irrelevant...
                      When you throw a rock, do you care about the Alpha?

                        a domain where wings doesn't provide any lift... hence where there is no Alpha.
                        Just avoid poorly choosing words then?

                        Not on a rock. But on a post-stall capable aircraft, it is.

                          Another in cockpit video, great sense of agility and speed due to the Wide fireld of view of the camera. Starts at 1min

                            Abiyt 10g+ during demo, it is wel documented from the cvery pilots that do it....
                            Keep praying your Atlantic puffin...
                            Only one thing true in your statements. Rafale FCS limit plane to 30. And it is a tactical choice. During tests it was seen at 110, -20 Kts
                            halloweene
                            what is this obsession with Rafale flight demonstration G?

                            every single G demand FCS allows momentary over-G. Any 9G rated aircraft can pull in excess of 9G for brief periods. No manufacturer wants to have to explain why a pilot augered into the side of Mt. Blanc with collision avoidance warnings blaring because the FCS only allowed a 9G pull up when 10 would have saved the pilot (hyperbole). There is play in these FCS control laws in certain maneuvers.

                            The only thing this this shows is something most of us have noticed in European flight demonstrations for some time..... they are allowed a lot more leeway and fun than the US demo teams that are highly scripted and dont allow any 9G maneuvers as part of normal demos. Does not change the fact that ALL aircraft with modern FCS are governed by weight, external loads, asymmetric loads in regard to G, pitch, and roll rates.

                              Funny, most of the current and future 5th and 6th Generation Fighters will include large internal fuel volumes.....(TFX, KFX, Tempest, NGF, PCA, NGAD, etc.)

                                As I said earlier also, the Rafale too see an increased in fuel fraction regarding its earlier gen sibling, the Mirage 2000.

                                EC 5/25 Corsair : the poor choice stands in the imperative form...

                                    Funny, you still can't get it right. That's a mandatory by-product of stealth designs, not a primary goal for everyday uses.

                                          In fact the Hawker Sea Fury, the Do 335 and i think even the Hawker Tempest was faster.
