Tail unit configuration is much different from the final Trident. Probably an artist's concept from aviation press back then.

Does anyone have accurate and detailed 3-views of the SO.9000 / SO.9050 / SO.9050 SE aircraft by any chance? I haven't come across anything too impressive online.

From FlugRevue 01/2002:

The picture posted by Hesham, I've seen in several adverts not directly related to the
Trident, so I would think, it was just an illustration of a "modern aircraft".

Well, you're quite right. And in the end, there's always the old say "Never believe
in 3-views, you didn't manipulate yourself". ;)
Maybe the best help, I can give is this one from "Les Prototypes De L'Aviation
Francais" by Jean-Claude Fayer.

Appears to be a three chamber Reaction Motors rocket similar to the X-1 four chamber unit. Unable to discern what type of air breather nest inside the wing pods.

The SO.9000 had a SEPR 481 rocket engine and two Turbomeca Marboré II jet engines,
the 9050 a SEPR 631 and two Dassault MD.60 Viper

Thanks again for the scans, Jens!

After an incident on 26-10-'54 where the rocket motors failed and the Marboré engines proved barely sufficient to lift the SO.9000 off the ground, the SO.9000 was re-equipped with Dassault MD30ASV4 Vipers of 745kgs thrust. (source: X-Planes Profile 4: http://www.luft46.com/hpmpub/hpmpub.html)

Of course it is "related" to the SO 9000 / 9050 but stylized to become a generic rocket fighter ....

Yes my dear Carbonel,

and maybe we can consider they were early attempts to rocket fighter with various shapes.

Your illustration comes from an advert. Advertising artists do not always copy reality ... hence my feeling what is there is just a "generic" design. Especially as the company for which the advert was created, SEPR, was a rocket engine manufacturer, not an airframe manufacturer ....

See document TU149_p12 above or my own Trident book page 14 where Philippe Ricco supplied the original (not redrawn) sketches by Servanty. That's what you are looking for. And don't forget what you are looking at are sketches dating from the late 40's (pre-Trident) while the SEPR advert which originates the whole thread is from 1959 when the Trident was dead. Mixing the two is IMHO an anachronism.

Why did so many 1940s and 1950s vintage jet prototypes have engines mounted on wing tips?
They produce ridiculous amounts of yaw after one engine quits.
