Looking at this video of a Rafale escorting a high-speed train (TGV)

I was wondering what the stall speed for the Rafale is at close to sea level altitude.

Is this information generally public for fighter aircraft? I could conceive this would be classified.

  • $\begingroup$ Not an answer to your question but a piece of related information for readers : the commercial top speed of this train is about 300 km/h (video comment says it was going 320km/h). $\endgroup$

  • $\begingroup$ Nice question! Note: with this train going to 320kph (198mph) I suppose it is far from stall speed $\endgroup$

  • $\begingroup$ Lower than a train top speed, I'd guess ;-D $\endgroup$

    $\begingroup$ From Dassault's site: "Approach speed: less than 120 knots". If approach speed is 1.3 Vs, Vs is less than 100 kt (185 km/h). And btw this train has a speed record of 574 km/h (310 kt), a video of the record on YT. Stall speed has to be understood as speed where CLmax is reached in unaccelerated straight and level flight. $\endgroup$

  • $\begingroup$ @mins to be more precise, this train class has a speed record of 574 km/h, but this was on a special project. $\endgroup$

80 knots for an aggressive pilot, as said here.

It is 148 km/h, a speed of fast but rather typical long range passenger train. No new technology is required for the train, this plane could easily follow a Pacific steam locomotive (top speed 203 km/h).

    $\begingroup$ It must be said that in airshows the airplane flies almost empty - no munitions, no external loads (even the missiles can be dummies) and little fuel in the tanks. With only 10t empty weight, it reaches those 80 knots at half the wing loading of a fully loaded plane. This would make the "real" stall speed closer to 113 knots. $\endgroup$ Jul 7 '17 at 19:15
