Saab 17
The Saab 17 is a Sweden, Swedish single-engine monoplane reconnaissance dive-bomber aircraft of the 1940s originally developed by AB Svenska Järnvägsverkstädernas Aeroplanavdelning, ASJA prior to its merger into Saab AB , Saab. It was the first all-metal stressed skin aircraft developed in Sweden. Design and development The project was initiated in response to a 1938 request from the ''Flygvapnet'' (Swedish Air Force) for a reconnaissance aircraft to replace the obsolete Fokker C.V, Fokker S 6 (C.Ve) sesquiplane. Design work began at the end of the 1930s as the L 10 by AB Svenska Järnvägsverkstädernas Aeroplanavdelning, ASJA, but once accepted by the ''Flygvapnet'' it was assigned the designations B 17 and S 17 for the bomber and reconnaissance versions respectively, and it became better known as the Saab 17. The design chosen was a conventional mid-wing Cantilever#Aircraft, cantilever monoplane with a long greenhouse canopy and a single radial engine in the nose. Control ...

Engineers From Stockholm
Engineers, as practitioners of engineering, are professionals who invent, design, build, maintain and test machines, complex systems, structures, gadgets and materials. They aim to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin , the origin of the Ir. in the title of engineer in countries like Belgium, The Netherlands, and Indonesia) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of a licensed professional engineer typically include a four-year bachelor's degree in an engineering dis ...

Wind Power In Sweden
Sweden has a total of 16.4 GW of wind power capacity at the end of 2023, the 5th highest in Europe and most per capita. Wind power produced 20.9% of national electricity generation in 2023, up from 0.3% in 2000. In July 2024, the Swedish Wind Energy Association (SWEA) projected that cumulative wind power capacity in the country will rise to 19.5 GW by the end of 2026. Longer-term projections from other market analysts estimate 30 GW of wind power capacity by 2030. Statistics Future developments The International Energy Agency's (IEA) Wind Technology Collaboration Programme 2021 report outlines Sweden's progress in wind energy. By 2021, Sweden had achieved a total wind power capacity of 12.116 MW from 4,679 turbines. This aligns with Sweden's environmental goals of reducing greenhouse gas emissions ( GHG) by 40% by 2030 and aiming for net-zero emissions by 2045. Additionally, Sweden targets 100% renewable electricity production by 2040. Wind power generation in Sweden is e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Power
Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely using wind turbines, generally grouped into wind farms and connected to the electrical grid. In 2024, wind supplied over 2,494 TWh of electricity, which was 8.1% of world electricity. With about 100 Gigawatt, GW added during 2021, mostly Wind power in China, in China and the Wind power in the United States, United States, global installed wind power capacity exceeded 800 GW. 30 countries generated more than a tenth of their electricity from wind power in 2024 and wind generation has nearly tripled since 2015. To help meet the Paris Agreement goals to Climate change mitigation, limit climate change, analysts say it should expand much faster – by over 1% of electricity generation p ...

Swedish Navy
The Swedish Navy () is the maritime service branch of the Swedish Armed Forces. It is composed of surface and submarine naval units – the Fleet (), formally sometimes referred to as the Royal Navy () – as well as marine units, the Amphibious Corps (). Founded under King Gustav Vasa in 1522, the Swedish navy is one of the oldest continuously serving navies in the world, celebrating its 500th anniversary in 2022. History Early Swedish kings ( 9th–14th centuries) organised a Swedish Navy along the coastline through . This involved combined rowing and sailing ships (without artillery). This system became obsolete with the development of society and changes in military technology. No later than in the 14th century, the duty to serve in was replaced by a tax. In 1427, when Sweden was part of the Kalmar Union (with Denmark and Norway), Swedish warships did however participate in the naval battle of Öresund against the Hanseatic League. It is unclear how this force was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saab 401
The Saab 401 MEFA was an experimental air-cushioned vehicle with a weight of 2 tons and capable of about 40 knots on open water with two people on board. A single prototype was built under contract to the Swedish Navy. The craft was first tested in 1963. The Navy retired the project in 1967 when it donated the 401 prototype to the Maritime Museum in Karlskrona Sweden. History The Saab 401 MEFA project was created in the late 1950s as a collaboration between Saab and the Royal Swedish Naval Materiel Administration, Karlskronavarvet ( Saab Kockums) and the Swedish National Aeronautical Research Institute (FFA). Later the project was continued on lean funds at FFA. MEFA is the Swedish acronym for ''Markeffektfarkost'' ( ground effect vehicle); the craft was also known as the "MEFAN". Its design was led by Olof Ljungström. Vickers-Armstrongs was contracted for engineering work. It was first tested March 4, 1963, in Norrköping. In January 1964, the 401 prototype was delivered ...

Hovercraft
A hovercraft (: hovercraft), also known as an air-cushion vehicle or ACV, is an amphibious craft capable of travelling over land, water, mud, ice, and various other surfaces. Hovercraft use blowers to produce a large volume of air below the Hull (watercraft), hull, or air cushion, that is slightly above atmospheric pressure. The pressure difference between the higher-pressure air below the hull and lower pressure ambient air above it produces lift, which causes the hull to float above the running surface. For stability reasons, the air is typically blown through slots or holes around the outside of a disk- or oval-shaped platform, giving most hovercraft a characteristic rounded-rectangle shape. The first practical design for hovercraft was derived from a British invention in the 1950s. They are now used throughout the world as specialised transports in disaster relief, coastguard, military and survey applications, as well as for sport or passenger service. Very large version ...

STAL Dovern
The STAL Dovern was a Swedish turbojet design of the early 1950s, named after a lake in Finspång municipality in Östergötland, Sweden. Intended to power the Saab 35 Draken, this aircraft was powered by the Rolls-Royce Avon instead. The Dovern did not enter production. Design and development The STAL company had been designing steam turbine engines and in the 1940s begun designing gas turbine engines. Their first running engine was the ''Skuten'', ground tested in 1949 but not flown. The Dovern was the next design, featuring a nine-stage axial compressor and single-stage turbine. First run in 1951, the engine was flight tested during 1953 using an Avro Lancaster provided by Air Service Training. The engine was installed underneath in a nacelle faired-in to the Lancaster's bomb bay. After several thousand hours of ground running and more than 300 hours of flight testing the engine was not selected, the Rolls-Royce Avon being preferred.Gunston 1989, p. 165. Applications *Avro ...
