SUBSIM: The Web's #1 resource for all submarine & naval simulations since 1997 SUBSIM Radio Room Forums > Silent Hunter 3 - 4 - 5 > SH4 Mods Workshop Walter Turbine Button After WWII the MK16 family was extended through Mod 8 and remained in use in submarines until the Walter turbine: ROBERT M. Several prototype boats used the Walter drive successfully, but there were always problems. These systems generally can be listed as closed-cycle diesel engines (CCDE), closed-cycle steam turbines, Stirling cycle engines, oxy-fuel supercritical carbon dioxide (s-CO 2) Brayton power systems, fuel cell systems, and nuclear power systems [2]. Fuel. Walter with hydrogen peroxide turbines used H2O2 as oxidizer. Displacing 76 tons and 22 metres in length, it accommodated a test crew of 4. Dec 11, 2020 · There they discovered the Glück auf bureau, which had played an important role in design of the Type XXVI submarine with Walter propulsion. Scopri (e salva) i tuoi Pin su Pinterest. It combined a diesel-electric powerplant for long-range duty (getting into the operations area and back) with a Walter turbine (for underwater attack use only). Initial design of submarine was based on project XXVI documentation taken from Germany as a trophy in 1945 Walter commanded respect for the hydrodynamics of innovative submarine hull design, as well as for the acceptance of his hydrogen peroxide power plant. 0 kn/ 3. However in 1944 when a review meeting of the Walter U-boat project was held it was discovered that fuel efficiency was terrible and the volatility of the fuel was a major problem. 11. Nov 29, 2004 · In the early 1930s, however, a brilliant German engineer, Dr. Idk why people think they are some vastly different type of submarine. In addition, at the suggestion of the future father of Russian democracy, Academician Sakharov, a gigantic (24 meters long!) T-15 nuclear torpedo was designed, on which it was also planned to install a Walter engine. Maohinery Weight and Size (al Turbine (b Area ot Heat Bxohangers (o Pumps So in the Walter turbine, HTP and kerosene are mixed together in a combustion chamber where they ignite to burn very fiercely. No significant events. The Swedish Navy's three Gotland-class submarines each use two Stirling cycle engines as an adjunct to their main diesel- While the Walter turbine would have allowed a very high submerged speed for chasing down a target, or escaping an attacker, the need to carry huge supplies of the highly-corrosive hydrogen peroxide fuel would have limited the use of the turbine. This system was a highly energy dense system and submerged speeds of more than 30 kts for a 1000 te submarine could At the same time that Walter was developing submarine engines, he was also applying his ideas to rocketry. Then comes the question of where do you place the turbines and how these turbines attached to the propulsion shaft. The ship, operated by a small team The submarine was powered by one Deutz SAA 8M517 supercharged 8-cylinder diesel engine producing a total of 210–230 metric horsepower (150–170 kW; 210–230 shp) for use while surfaced and one Walter gas turbine producing a total of 2,500 metric horsepower (1,800 kW; 2,500 shp) for use while submerged. ) The Kriegsmarine was pinning its hopes on the Walter turbine system which produced unbelievable performance for submarines at that time. Permanganates of sodium, potassium, or calcium were considered for catalysts to break H 2 O 2 to O 2 + H 2 O. 140 votes, 14 comments. Hellmuth Walter, a German scientist, developed a turbine propulsion system using oxygen generated by hydrogen peroxide to operate the turbine while submerged. None. Germany had started experimenting with this technology early in the Second World War and developed it into the Walter cycle. Reply to this HMS Explorer is the second ship to bear the name; her predecessor was an unarmed experimental Walter-turbine submarine based on the captured high test peroxide (HTP) powered German Type XVIIB submarine U-1407 launched in 1956 and scrapped in 1965. Its range was 50 nmi (93 km; 58 mi) at 28 knots (52 km/h; 32 mph). High speed operation at shallow depths The armament consisted of ten torpedo tubes, four of them on the bow. this is what sets this sub apart from being a deckgunless, sterntubeless IXD2 Oct 31, 2011 · 61. Thus, whilst the "Walter" turbine was taken for study to Annapolis, the hull was retained unused at PNY. Though both closed-cycle turbines and diesels had been introduced, both still needed development, so a stopgap high-power electric boat was produced, using mostly established technology. The exhaust and condensed steam were then expelled overboard. sim and it is located in the: Data\Submarine\NSS_Uboat18 Once you've opened the file in the 3ditor, go to unit_Submarine --> Ranges --> HydroPeroxidPropulsion --> miles = edit the value (put like 99000 or something). 08. 2,910 nmi at 8. [3] So in the Walter turbine, HTP and kerosene are mixed together in a combustion chamber where they ignite to burn very fiercely. Pin. hlixwv gijs gbym vhp cirxkz cmzxx pxpw sww vpc qqyz
