It might be possible to mitigate that to some extent. However the screw is still rigid whereas a track can change its shape follow the terrain. That means you can use it screw propulsion for e.g. a reconnaissance vehicle in very adverse terrain but not for a battle tank, APC or medivac vehicle.<br \/>\nDirectional stability may not be the best, it should be possible to use a regular mechanical instead of a series hybrid transmission. So the upsides are lower system complexity, better fuel economy and, lower drivetrain &amp; fuel weight.<\/p>\n<p>These are Russian screw vehicles, which seems to be an area in which they did some development.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/capture1005200490559_am.jpg\" title=\"Capture1005200490559_am\" alt=\"Capture1005200490559_am\" style=\"margin: 0px 5px 5px 0px\" border=\"0\" height=\"273\" width=\"350\" \/><br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/capture1005200490636_am.jpg\" title=\"Capture1005200490636_am\" alt=\"Capture1005200490636_am\" border=\"0\" height=\"516\" width=\"350\" \/><\/p>\n<p>I figure the plan was to make their enemy either scared shitless or paralyzed by awe of Russian mechanized genius\/madness. Or both.<br \/>\nI found out that the original screw propulsion vehicle was designed in 1944, during WWII, by Johannes Raedel, a member of the German Army and veteran of the Eastern Front with Russia.  (Note: Raedel was originally spelled R&#8217;a&#8217;del, with an umlaut).  He had observed that in the deep snows of Russia, tanks would dig out the snow under the tracks, and the tank would become high centered on snow pressed under the belly of the tank.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/screw_vehicle.jpg\" title=\"Screw_vehicle\" alt=\"Screw_vehicle\" border=\"0\" height=\"419\" width=\"500\" \/><br \/>\nAccording to Siegfried Raedel, son of Johannes..&#8221;The idea evolved while looking at a meat mincer,  also employing a screw type of compression. He convinced army headquarters in  Berlin to allow him to make a prototype of this machine.  At that time, Austria  was annexed to Germany already and he was dispatched to the Austrian Alpine  vehicle test centre at St. Johann in Tyrol.  Using whatever materials were  available he built this prototype during the period of 10th Feb 1944 to 28th  April 1944.  It was tested extensively and the first page of this report is  attached, together with a few pictures of the original.  It was very slow, but it  would pull 1 ton!  It also had good climbing capabilities. It would penetrate  about 30cm into the snow, no more.&#8221;<\/p>\n<p>The photos below are of Johannes testing the vehicle in Tyrol.  The woman and children were at a lodge at the top of a mountain, which the vehicle had climbed during testing.<br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/nazi_vehicle.jpg\" title=\"Nazi_vehicle\" alt=\"Nazi_vehicle\" border=\"0\" height=\"414\" width=\"500\" \/><br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/screw_drive_vehicle.jpg\" title=\"Screw_drive_vehicle\" alt=\"Screw_drive_vehicle\" border=\"0\" height=\"412\" width=\"500\" \/><br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/patentpending.blogs.com\/patent_pending_blog\/images\/wwii_german_vehicle.jpg\" title=\"Wwii_german_vehicle\" alt=\"Wwii_german_vehicle\" border=\"0\" height=\"410\" width=\"500\" \/><\/p>\n<p>Siegfried pointed out that &#8220;something in the order of 7 tons  of patent papers were taken out of Germany after the war.
