Des soldats allemand équipés de jet-packs pendant la seconde guerre mondiale.
Cette idée terrifiante n’est pas un fantasme :  l’image ci-contre est une reconstitution d’un véritable projet nazi. Découvrez le “Himmelstürmer” !
Le but était d’amener des soldats allemands derrière les lignes Alliées. Un propulseur fournissait une poussée verticale ou horizontale dans le dos du soldat, et un autre propulseur équilibrait le tout en poussant verticalement depuis l’avant du soldat.
Une combustion courte conférait à l’appareil une faible consommation de  carburant et lui permettait de ne pas chauffer et de ne requérir aucune tenue de protection particulière.
Heureusement pour les Alliés, ce gadget est arrivé trop tard dans la guerre. Il permettait tout de même de sauter 180 pieds à une altitude de 50 pieds, et permettait donc de dépasser toute fortification ou barbelés.

The German Himmelstürmer of World War II

During World War II, Germany made late-war experiments of strapping two wearable shortened Schmidt pulse jet tubes of low thrust to the body of a pilot. The working principle was the same as the Argus As 014 pulse jet that powered the Fieseler Fi 103 flying bomb, though the size was much smaller.

The device was called "Himmelstürmer" (Skystormer) and operated as follows: when the flier ignited both engines simultaneously the tubes began to pulse modulate. The angled rear tube strapped to the flier's back provided both lift and forward thrust while the chest mounted deflector tube of lower thrust maintained a constant upward thrust. This lifted the flier up and forward. By opening the throttle to the rear tube, calculated "jumps" could be made of up to 60 meters (180 ft) at low altitude (under 50 ft, 15 m). The tubes consumed very little fuel but not much could be carried either.

The intended use for this device was for German engineer units to cross minefields, barbed wire obstacles, and bridgeless waters. The device was never intended for troop use, despite the imaginative depiction of it in that role in the comic book and film The Rocketeer (which was a prop bearing no resemblance to the real device).

At the end of the war this device was handed over to Bell Aerosystems which tested it on a tether out of fear of harm as no test flier was willing to risk his life with the German machine. What became of the device is not known.
