GERMAN NAVY Records, 1854-1944 Reels M291-336A
AUSTRALIAN JOINT COPYING PROJECT GERMAN NAVY Records, 1854-1944 Reels M291-336A Historical Section The Admiralty Whitehall, London SW1 National Library of Australia State Library of New South Wales Filmed: 1959 CONTENTS Page 3 Historical note 5 Records of the Reichsmarine Amt, 1854-1913 9 Records of the Admiralstab der Marine, Abteilung B, 1880-1917 15 Records of the Oberkommando der Marine, Seekriegsleitung, 1939-44 16 Charts produced by the Reichsmarine, 1940-41 2 HISTORICAL NOTE The Imperial German Navy (Kaiserliche Marine) was created in 1871, succeeding the small navies of the Kingdom of Prussia and the North German Federation (1867-70). Its existence was recognised in the new constitution, but until 1888 it was commanded by generals and its role was mainly limited to coastal defence. In contrast to Chancellor Otto von Bismarck, Emperor Wilhelm II aspired to create a great German maritime empire. He became Grand Admiral of the German Navy and in 1889 made major changes to the organisation of the Admiralty. It was split into the Navy Cabinet, (Marine-Kabinett) responsible for appointments, promotions and issuing orders to naval forces, the Imperial High Command (Kaiserliche Oberkommando der Marine), responsible for ship deployments and strategy, and the Navy Office (Reichsmarine Amt ) responsible for the construction and maintenance of ships and obtaining supplies. The Navy Office was headed by a State Secretary, who was responsible to the Chancellor and who advised the Reichstag on naval matters. In 1899 the Imperial High Command was replaced by the Imperial Admiralty Staff (Admiralstab). Headed by Admiral Alfred von Tirpitz, the Navy Office, which was located in the Leipzigerplatz in Berlin, was the more influential body. -
AIR-INDEPENDENT PROPULSION – AIP Technology Creates a New Undersea Threat Page 1 of 6
AIR-INDEPENDENT PROPULSION – AIP Technology Creates a New Undersea Threat Page 1 of 6 AIR-INDEPENDENT PROPULSION AIP Technology Creates a New Undersea Threat Walter Type XVIIB up on the stocks. Pictured above is the German Walter Type XVIIB U-1406, partially dismantled shortly after the end of World War II. U-1406 was turned over to the U.S. Navy as a war prize and soon disposed of, but the Royal Navy later operated her sister ship, U-1407, as HMS Meteorite to gain experience in hydrogen-peroxide propulsion technologies. As interest mounts in "Air-Independent Propulsion" (AIP) for enhancing the performance of small, defensive submarines, a serious new underwater threat is developing in littoral waters. Increasingly, smaller nations unwilling or unable to accept the high cost of nuclear power to achieve greater underwater endurance and longer range are turning to lower-priced and less ambitious alternatives that still offer significant operational advantages over conventional diesel- electric submarines. The best of the latter boats, such as the German-designed Type 209 or the Russian KILO, can remain submerged on battery at slow speed for periods on the order of three to five days. But now, several AIP schemes in development or already in operation can increase slow-speed endurance to as much as three weeks or a month. While still dwarfed by the potential of nuclear power, AIP offers diesel submarines a remarkable increase in capability. AIP - The Early History Despite their initial successes, submarine pioneers were still eager to find some means to free their boats from the necessity of surfacing frequently for access to the atmospheric oxygen demanded by the gasoline or diesel engines that charged the batteries. -
H2O2) Is Commonly Used for Cleaning Cuts and Sores, and That a Bottle of Hydrogen Peroxide Can Turn a Brunette Into a Blonde
Hydrogen Peroxide and Sugar Most people know that Hydrogen Peroxide (H2O2) is commonly used for cleaning cuts and sores, and that a bottle of hydrogen peroxide can turn a brunette into a blonde. Yet, how many people know that hydrogen peroxide can also be used as a powerful rocket fuel? And how many people know that hydrogen peroxide accelerated the jet car Peroxide Thunder to 450 mph in 3.4 seconds? Hydrogen peroxide is commonly used (in very low concentrations, typically around 5%) to bleach human hair, hence the phrases "peroxide blonde" and "bottle blonde". It burns the skin upon contact in sufficient concentration. In lower concentrations (3%), it is used medically for cleaning wounds and removing dead tissue. Combined with urea as carbamide peroxide, it is used for whitening teeth. Hydrogen peroxide tends to decompose exothermically into water and oxygen gas. The rate of decomposition is dependent on the temperature and concentration of the peroxide, as well as the presence of impurities and stabilizers. The use of a catalyst (such as manganese dioxide, silver, or the enzyme catalase) vastly increases the rate of decomposition of hydrogen peroxide. High strength peroxide (also called high-test peroxide, or HTP) must be stored in a vented container to prevent the buildup of pressure leading to the eventual rupture of the container. In the 1930s and 40s, Hellmuth Walter pioneered methods of harnessing the rapid decomposition of hydrogen peroxide in gas turbines and rocket engines. Hydrogen peroxide works best as a propellant in extremely high concentrations of 90% or higher. Hydrogen peroxide - Wikipedia Online Encyclopedia Hydrogen peroxide (H2O2) can store energy in the form of chemical energy, similar to hydrogen. -

Alternative Power Sources for Submarines
Special brandstoffen By ing. R.P. Dingemanse Alternative Power Sources for Submarines The turn of the twentieth century marked a change in the development of submarines. Diesel electric propulsion would become the dominant power system. Batteries were used for running submerged and gasoline or diesel engines were used on the surface and during snorting to recharge the batteries. Early boats used gasoline, but quickly gave way to diesel, because of reduced flammability. Yet, over the years, other power sources have been investigated, and successfully applied.

(AIP) Submarine – a Weapon of Choice for the 21St Century Dominik Kimla, Industry Analyst – Aerospace, Defence & Security
Conventional (AIP) Submarine – a Weapon of Choice for the 21st Century Dominik Kimla, Industry Analyst – Aerospace, Defence & Security Introduction The potential implications of shifting US interests/military doctrine from the Atlantic to the Pacific, and more specifically to South-East Asia, as well as the superpower ambitions of China and its growing tension with neighbours demands a closer look from the global security and defence industry. The US military solution for national security challenges from the Asia-Pacific (APAC) region is the Air-Sea Battle strategy. In a potential worst-case scenario, where the US Navy has to confront the Anti-Access / Area Denial operational concept of its adversary(ies), Frost & Sullivan anticipates a significant role for conventional submarines in the confrontation. or the 21st or Century The modern non-nuclear, conventional diesel-electric submarine (SSK) with air- independent propulsion (AIP) system is a complex, multi-role and extremely powerful weapon system. The submarine is able to deploy a wide range of weapons such as: torpedoes, anti-ship missiles, land attack missiles, mines, unmanned underwater vehicles, self defence systems and even provide accommodation and support for a team of Special Forces. Consequently, the vessel can conduct various missions from anti submarine, anti surface vessels warfare through land strikes with cruise missiles to intelligence, surveillance and reconnaissance operations. Therefore, modern SSKs can play the role of a semi strategic weapon which will have a decisive effect on future air-sea battlefields. Naval operations have changed significantly compared to the Cold War period. Operations at sea have moved from the ‘‘blue water’’ open ocean to the ‘‘brown water’’ shallow, costal environment. -

Nesman Aerospace Engineer at NASA Marshall Space Flight Center Special Member Karen A. Thole Professor of Aerospace Engineering Head of the Department of Mechanical and Nuclear Engineering *Signatures are on file in the Graduate School iii ABSTRACT The combustion instability problem in liquid-propellant rocket engines (LREs) has remained a tremendous challenge since their discovery in the 1930s. Improvements are usually made in solving the combustion instability problem primarily using computational fluid dynamics (CFD) and also by testing demonstrator engines. Another approach is to use analytical models. Analytical models can be used such that design, redesign, or improvement of an engine system is feasible in a relatively short period of time. Improvements to the analytical models can greatly aid in design efforts. A thorough literature review is first conducted on liquid-propellant rocket engine (LRE) throttling. Throttling is usually studied in terms of vehicle descent or ballistic missile control however there are many other cases where throttling is important.
