It was a typography mistake or the foreseen name of the 2415 was, at first, 2412. But, finally, the second prototype of the "Grognard" (the subject of the article) was named 2415, not 2412.

At the beginning of the article, it's wrote, in French, that the 2412 was the second version of the 2410... And not of another plane, whatever it is ..

Next tests in Toulouse of SE.2412, second modified version of SE.2410, equipped, like the precedent, with two Nene turbojet engines built by Hispano-Suiza. It is Nadot who will test this aircraft, likely to be a very modern light bomber
And the article is from 10.1950 and the SE.2415 made its first flight on 14.02.1951 with Pierre Nadot as pilot.

I spoke about it before,it was a large flaying crane helicopter Project,with a payload 16.000-24.000 1b,and designed
in co-operated with Agusta and a company from Germany, in 1959,and I suggested before the Germany company
maybe was Meckle or Borgward ?.

Hi!
The SNCASE SE2410 Grognard was designed as a single-seater, low-level ground attack aircraft. The French Army Air Corps is under development in the 1950s, but the program was discontinued due to Sud-Ouest Vautour II.
SE.2410 Grognard IOriginal specifications; one prototype.
SE.2415 Grognard IIRevised two-seat design with changes to wing, fuselage and cockpit; one prototype.
SE.2418 GrognardUnbuilt production single-seat version with Rolls-Royce Tays replacing the Nene engines in the prototypes.

Oh boundary layer suction air intake!!
Thanks a lot Justo-san.:)
I think that this air intake had a fence that separates the boundary layer from the laminar flow.
The inhaled boundary layer may be discharged from somewhere, or accelerated by the ejector effect of the laminar intake air, mixed, and supplied to the engine.
To me, it looks like there is a baffle fence at the air intake that takes in laminar air.

I'm not happy with this huge dump of scans with precious little in the way of sources being mentioned here from the usual suspects. There are poor scans, scans of pictures of models of dubious authenticity... Take some time to label your pictures, crop the scans, and generally be fair to the original sources.

I can see a lot of scans from Les Avions de Combat Francais in a short time frame here, I'm not sure this is ethically justified.
