	uboat.net - U-boat Types
		Walter was a brilliant engineer that in 1933 worked on a new gas turbine at the Germaniawerft shipyard in Kiel and there his idea of a closed circuit propulsion system was born.
		The V-80 boat was designed by Walter and Germaniawerft in Kiel and built in the greatest secrecy on a slipway surrounded by a large fence.
		Thus the Walter boats did not have any real effect on the war but they were a very interesting development and according to admiral Dönitz with a little courage and vision they could have been in service 2 years earlier and then they certainly would have had enormous impact on the war.

		Hydrogen peroxide (H2O2) is a clear liquid, slightly more viscous than water, that has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant and (in high concentrations as high test peroxide) as an oxidizer or monopropellant in rockets.
		In 1950 he emigrated to the United States and joined the Worthington Corporation in Harrison, New Jersey, eventually becoming vice-president of research.

	U-260 (Site not responding. Last check: 2007-10-07)
		Walter had suggested that submarines could run under water on their diesel engines if they could breathe fresh air and exhaust waste gases through a long tube or snorkel that extended above the water; much greater distances and speeds could be achieved while traveling underwater.
		Walter then discussed the technical aspects of his proposals with marine specialists Gabler and Heep The device became known as 'Walter's snorkel' and was first constructed and tested in June 1943.
		Walter was decorated with the Knight's Cross for War Services, the highest order of merit ever given to a civilian in peacetime.

	Hellmuth Walter
		Hellmuth Walter was an engineer who saw the limitations of conventional air-breathing, internal combustion engines; complexity, inefficiency, low power-to-weight ratio, and above all a heavy reliance on drawing in atmospheric air to function.
		His knowledge of chemistry led him to propose that an engine powered by an oxygen-rich fuel which could develop power by combustion without the need for atmospheric air would have a variety of uses, not least of which were underwater applications such as submarines and torpedoes.
		But used as the primary power plant in an interceptor, the Walter motor could propel a piloted craft to be amongst a flight of attacking bombers in a few minutes rather than the forty five that a standard climb to height would normally need.

	U-boat U-260 (Site not responding. Last check: 2007-10-07)
		As early as 1933, Hellmuth Walter had suggested that submarines could run at full speed underwater on their diesel engines by introducing air from the atmosphere and expending exhaust gases through a vertical airmast, that could be raised or lowered as required.
		Walter incorporated a ball or float in the head-valve at the highest point in the mast to prevent seawater entering in rough weather.
		The airmast became known as a Walter Snorkel and the first was made in June 1943.

		Prior to the start of World War II, Hellmuth Walter had started experimenting with the use of hydrogen peroxide as a fuel for various engines.
		The fuel was particularly useful as a rocket fuel, as it would "ignite" (although it was actually just decomposing) simply by being passed through a metal catalyst.
		Meanwhile Walter had started work on a newer hot engine which added a fuel of and methanol, designated C-Stoff, that burned with the oxygen-rich exhaust for added thrust.

	AIR-INDEPENDENT PROPULSION — AIP Technology Creates a New Undersea Threat (Site not responding. Last check: 2007-10-07)
		Walter's primary design goal was high underwater speed, rather than long endurance, and indeed, his first submarine prototype, the experimental V80, reached 28.1 knots submerged in its 1940 trials - at a time when conventional submarines were limited to 10 knots or less.
		Additionally, Walter himself and several of his key staff were brought to England and there collaborated with Vickers, Ltd. for several years in the design of more advanced hydrogen peroxide systems.
		Although it is a remarkable tribute to Hellmuth Walter's engineering genius that he fielded a fully functional - if troublesome - 5,000-horsepower AIP system in 1945, the maximum power output of current AIP installations is typically on the order of 400 horsepower (300 kilowatts).

		Hellmuth Walter, working at the Germania-Werft, was tasked with devising a wakeless torpedo motor.
		With this success, Walter was given the support to build the HWK RI rocket motor, fueled with T-Stoff (a stabilizer of oxyquinoline or phosphate), hydrogen peroxide, and Z-Stoff (an aqueous solution of calcium permanganate).
		However, his decision to replace the conventional prop engine for his DFS 194 with a Walter R I-203 rocket engine was to be perhaps the sole reason for the revival of interest in rocket propelled aircraft.

	The AIP Alternative
		The Soviet-designed AIP system used liquid oxygen and diesel fuel to operate a closed-cycle diesel (CCD) engine that was installed in the submarine M-401 for an experiment that lasted from 1940 to 1945.
		In Germany, Professor Hellmuth Walter, an engineer, developed an AIP system that used highly concentrated hydrogen peroxide to produce steam for a turbine-driven submarine.
		As with the Soviet system, the Walter system was plagued by numerous technical and safety problems.

		This was the fore-runner of the now being introduced in various world navies, the AIP (Air Independent Propulsion) type e.g., the under construction Agosta 90 class for the Pakistan Navy.
		The German Walter Type XXVII under trials in early forties achieved a maximum under water speed of 25 knots for brief periods and sustained under water speed of 20 knots for five and a half hour.

		In 1933, RGG had been reorganised into the Deutsche Forschungsanstalt für Segelflug (DFS - German Institute for Sailplane Flight) and the Delta IV and Delta V were designated as the DFS 39 and DFS 40 respectively.
		In early 1939, the Reichsluftfahrtsministerium (RLM) — (Reich Aviation Ministry) transferred Lippisch and his team to work at the Messerschmitt factory to design a high-speed fighter aircraft around the rocket engines then under development by Hellmuth Walter.
		They quickly adapted their then-current design, the DFS 194 to rocket power, successfully flying in early 1940.

		In fact, the submarine was often referred to as -HMS Exploder." The experiments were stopped when the Royal Navy also shifted to nuclear submarines.
		From then on the Soviets also focused on nuclear propulsion-but they did carry out some further AIP research and development (R&D) for the diesel submarines they continued to build.
		The CCD engines and the Walter steam turbines represented sound theoretical approaches to AIR Increases up to 400 percent in submerged time and/or range were possible in the better systems; however, they still could not be made sufficiently safe for routine fleet operations.
