Himmelstürmer Flightpack

From EverybodyWiki Bios & Wiki


The Himmelstürmer (figurative translation: "Sky Trooper" but literally "heaven stormer" ) Flightpack, or Einpersonenfluggerät, was a flightpack invented by Nazi Germany late in the war[1][2][3][4] Its intention was not to achieve flight for the user, but to jump over obstacles and waterways that would otherwise be difficult to traverse on foot. The jetpack, or flightpack consisted of a larger rocket on the back for propulsion, and a smaller one on the front for steering. The propulsion was achieved by the use of a Schmidt pulse jet,[5] developed originally by Paul Schmidt (inventor) who submitted preliminary design patents as early as 1931.[6] Though he didn't invent the pulse engine, engineer Paul Schmidt (inventor), pioneered a more efficient design based on modification of the intake valves (or flaps), earning him government support from the German Air Ministry in 1933.[7][8] Pulse jets were also used by V1 rockets, which Schmidt was also involved with.

Because the flight time was so short the soldier wore no special flight gear, each simply wore the standard Feldbluse, and were armed with standard infantry weapons and two Stielhandgranates for deploying though the open tops of enemy vehicles, occupied buildings, groups of infantry or other opportune targets while in flight above them.[9] The unit consumed fuel rapidly, so it had to be turned off by the operator as soon as they landed.[10] Because of the rapid consumption of fuel, the user was restricted in the speed they could travel at [11] Both rockets had to be operated simultaneously to work, the smaller rocket in front having controls for piloting. Schmidt paired the two pulse jets so the thrust from the larger pulsejet, worn on the back, created a thrust vector through the centre of the mass of the whole "vehicle". This prevented it from "tumbling" and kept the vehicle stable and on its intended trajectory. The smaller pulsejet generated only enough force for directional control.[12] Both of the pulse tubes were angled away from the operator's body. In operation, the thrust difference between pulse tubes had a stabilising push/pull/lift effect.

The devices were tested by the Wehrmacht late in 1944, but the war ended before they could be used.[13] The device may have been taken by United States Military forces as part of Operation Paperclip, and possibly influenced postwar US designs.[14]
