Saalina
Saalina was a boat made by SAAB after World War II. When the war ended the interest in making fighter planes went down and SAAB needed something to use all the aluminum sheets they had stored. Kurt Sjögren thus designed an aluminium boat and 250 boats were made. However, the cost of the boats became very high since they were made like the aircraft with every rivet polished down. Then there was a problem with that the aluminium rivets did not stand seawater and quickly turned the boats into sieve A sieve (), fine mesh strainer, or sift is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet m ...s. ;Measurements * Length: * Width. {{convert, 1.45, m, in, 1 External links Vårträffen 2003- includes pictures Saab vehicles ...

Saab AB
Saab AB (originally , , acronym SAAB), with subsidiaries collectively known as the Saab Group (), is a Swedish aerospace and defense company, defence company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken in Linköping. The company was formally founded by AB Bofors in 1937, by reforming the aero engine division of company NOHAB (founded in 1930), located in Trollhättan, into a proper aircraft manufacturer. It would soon merge with aircraft manufacturer AB Svenska Järnvägsverkstädernas Aeroplanavdelning, ASJA (founded in 1931), located in Linköping, in 1940, which had it own design bureau and is considered the spiritual predecessor to today's Saab AB. This formed the SAAB-Concern (business), concern, with the factory in Trollhättan becoming ''SAAB/T'' and the factory in Linköping (previously ASJA) becoming ''SAAB/L'' and design headquarters. From 1947, Saab started producing autom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boat
A boat is a watercraft of a large range of types and sizes, but generally smaller than a ship, which is distinguished by its larger size or capacity, its shape, or its ability to carry boats. Small boats are typically used on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats (such as whaleboats) were intended for offshore use. In modern Navy, naval terms, a boat is a vessel small enough to be carried aboard a ship. Boats vary in proportion and construction methods with their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation, fishing, and sport. Fishing boats vary widely in style partly to match local conditions. Pleasure boat, Pleasure craft used in boating, recreational boating include ski boats, Pontoon (boat), pontoon boats, and sailboats. House boats may be used for vacationing or long-term residence.

World War II
World War II or the Second World War (1 September 1939 – 2 September 1945) was a World war, global conflict between two coalitions: the Allies of World War II, Allies and the Axis powers. World War II by country, Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks in World War II, Tanks and Air warfare of World War II, aircraft played major roles, enabling the strategic bombing of cities and delivery of the Atomic bombings of Hiroshima and Nagasaki, first and only nuclear weapons ever used in war. World War II is the List of wars by death toll, deadliest conflict in history, causing World War II casualties, the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Allied-occupied Germany, Germany, Allied-occupied Austria, Austria, Occupation of Japan, Japan, a ...

Fighter Plane
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers, are designed from the outset for dual ro ...

Kurt Sjögren
Kurt is a male given name in Germanic languages. ''Kurt'' or ''Curt'' originated as short forms of the Germanic Konrad/Conrad, depending on geographical usage, with meanings including counselor or advisor. Like Conrad, it can also a surname and less uncommon variations in Germanic languages including , Curd, , , Kord, Kort, Kurth, and Kurtu. In Turkish, Kurt means "wolf" and is a surname and less commonly a given name in numerous Turkic countries.

Rivet
A rivet is a permanent mechanical fastener. Before being installed, a rivet consists of a smooth cylinder (geometry), cylindrical shaft with a head on one end. The end opposite the head is called the ''tail''. On installation, the deformed end is called the ''shop head'' or buck-tail. Because there is effectively a head on each end of an installed rivet, it can support Tension (physics), tension loads. However, it is much more capable of supporting Shear force, shear loads (loads perpendicular to the axis of the shaft). Fastenings used in traditional wooden boat building, such as copper nails and clinch bolts, work on the same principle as the rivet but were in use long before the term ''rivet'' was introduced and, where they are remembered, are usually classified among nails and bolts respectively. History Solid rivets are one of the oldest and most reliable types of fasteners, having been found in archeology, archaeological findings dating back to the Bronze Age. Rivet ...

Seawater
Seawater, or sea water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 35 ppt, 600 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately of dissolved salts (predominantly sodium () and chloride () ions). The average density at the surface is 1.025 kg/L. Seawater is denser than both fresh water and pure water (density 1.0 kg/L at ) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases. At typical salinity, it freezes at about . The coldest seawater still in the liquid state ever recorded was found in 2010, in a stream under an Antarctic glacier: the measured temperature was . Seawater pH is typically limited to a range between 7.5 and 8.4. However, there is no universally accepted reference pH-scale for seawater and the difference between measuremen ...

Sieve
A sieve (), fine mesh strainer, or sift is a tool used for separating wanted elements from unwanted material or for controlling the particle size distribution of a sample, using a screen such as a woven mesh or net or perforated sheet material. The word ''sift'' derives from ''sieve''. In cooking, a sifter is used to separate and break up clumps in dry ingredients such as flour, as well as to aerate and combine them. A strainer (see colander), meanwhile, is a form of sieve used to separate suspended solids from a liquid by filtration. Sieving Sieving is a simple technique for separating particles of different sizes. A sieve such as used for sifting flour has very small holes. Coarse particles are separated or broken up by grinding against one another and the screen openings. Depending upon the types of particles to be separated, sieves with different types of holes are used. Sieves are also used to separate stones from sand. Sieving plays an important role in food ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
