Rotter Karakán
The Rotter Karakán or just the Karakán was a high performance Hungarian single seat sailplane. Two were built and set many national gliding records in the years before World War II. Design Like several other glider designers of the early 1930s, Lajos Rotter was impressed by Alexander Lippisch's Wien of 1929 and his high performance, single seat Karakán bears its influence. Like the Wien, the Karakán was a high aspect ratio sailplane with a two-piece high wing with a rectangular plan centre section and long, straight tapered outer panels. Both had thick section wings at the root which became progressively thinner over the outer panels. On both designs, ailerons occupied the whole trailing edge of these outer panels. Structurally, the wings were similar, with two spars of unequal strength; the forward spar beams were part of plywood covered D-boxes around the leading edges and the rear spar was a lighter simple beam. The wings were fabric covered behind the main spar, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Aircraft Fabric Covering
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are the pioneering all-wood monocoque fuselages of certain World War I German aircraft like the LFG Roland C.II in its wrapped ''Wickelrumpf'' plywood strip and fabric covering. Early aircraft used organic materials such as cotton and cellulose nitrate dope; modern fabric-covered designs usually use synthetic materials such as Dacron and butyrate dope for adhesive. Modern methods are often used in the restoration of older types that were originally covered using traditional methods. Purpose/requirements The purposes of the fabric covering of an aircraft are: * To provide a light airproof skin for lifting and control surfaces. * To provide structural strength to otherwise weak structures. * To cover other non-lifting parts of an aircr ...

Hungarian Technical And Transportation Museum
The Magyar Műszaki és Közlekedési Múzeum ("Hungarian Technical and Transportation Museum"), still often referred to with its former name, Közlekedési Múzeum ("Transportation Museum"), is a museum in Budapest, Hungary. It is one of Europe's oldest transportation collections. The museum has a unique collection of locomotives and railway cars on a 1:5 scale. This means that a locomotive of, for example, 10 m length is reproduced with all details in a 2 m length model. The models represent a wide range of railway technology. The museum shows also a locomotive and wagon in real size with a railway station of the 1900s. In other parts of the museum are shown: * The history of road traffic: horse-drawn and machine-driven vehicles, road and bridge building with a collection of old cars, motorcycles and bicycles. * The history of sailing. Sailing from the prehistoric ages; the history of Hungarian boat manufacturing, showed by models. * On a location deeper in the park there i ...

Silver C
The International Gliding Commission (IGC) is the international governing body for the sport of gliding. It is governed by meetings of delegates from national gliding associations. It is one of several Air Sport Commissions (ASC) of the Fédération Aéronautique Internationale (FAI), or "World Air Sports Federation". FAI is the world body for sporting aviation and the certification of world records for aeronautics and astronautics and was founded in 1905. When the IGC was founded in 1932, it was called CIVV (Commission Internationale de Vol à Voile) and has also been called CVSM (Commission de Vol Sans Moteur). It is the FAI commission responsible for the international competitions, records and badges that apply to gliders and motor gliders. The term "sailplanes" is sometimes used. Hang gliders and paragliders have a separate body called the FAI CIVL Commission, which stands for "Commission Internationale de Vol Libre". The World Gliding Championships are organised every ...

4th World Scout Jamboree
The 4th World Scout Jamboree ( Hungarian: ''4. Cserkész Világdzsembori''), a gathering of Boy Scouts from all over the world, was hosted by Hungary and held from 2 to 13 August 1933. It was attended by 25,792 Scouts, representing 46 different nations and additional territories. They encamped around the Royal Palace in the Royal Forest of Gödöllő, about 11 miles (18 kilometres) from the capital of Budapest. In attendance It was the second-to-last Jamboree for the founder of Scouting, Robert Baden-Powell. Baden-Powell and Hungarian head of state, Regent Horthy, addressed the Scouts from the grandstand built to accommodate over 5000 guests during an opening ceremony at the rally ground. Regent Horthy told the Scouts, The Jamboree Camp Chief was the Chief Scout of Hungary, Count Teleki Pál, a member of the International Committee who had previously been and would later once again become Prime Minister of Hungary.

All-moving Tailplane
A stabilator is a fully movable aircraft horizontal stabilizer. It serves the usual functions of longitudinal stability, control and stick force requirements otherwise performed by the separate parts of a conventional horizontal stabilizer and elevator. Apart from reduced drag, particularly at high Mach numbers, it is a useful device for changing the aircraft balance within wide limits, and for reducing stick forces. Stabilator is a portmanteau of ''stabilizer'' and ''elevator''. It is also known as an all-moving tailplane, all-movable tail(plane), all-moving stabilizer, all-flying tail(plane), all-flying horizontal tail, full-flying stabilizer, and slab tailplane. General aviation Because it involves a moving balanced surface, a stabilator can allow the pilot to generate a given pitching moment with a lower control force. Due to the high forces involved in tail balancing loads, stabilators are designed to pivot about their aerodynamic center (near the tail's mean quarter-chord ...

Balanced Rudder
Balanced rudders are used by both ships and aircraft. Both may indicate a portion of the rudder surface ahead of the hinge, placed to lower the control loads needed to turn the rudder. For aircraft the method can also be applied to elevators and ailerons; all three aircraft control surfaces may also be mass balanced, chiefly to avoid aerodynamic flutter. Ships A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection. A degree of semi-balance is normal to avoid rudder instability i.e. the area in front of the pivot is less than that behind. This allows the rudder to be moved with less effort than is necessary with an unbalanced rudder. The b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic Drag
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Canopy
An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft. An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck. A canopy's shape is a compromise designed to minimize aerodynamic drag, while maximizing visibility for pilots and other crewmembers. History Very early aircraft had no canopies. The pilots were exposed to the wind and weather, although most flying was done in good weather. Through World War I most aircraft had no canopy, although they often had a small windshield to deflect the prop wash and wind from hitting the pilot in the face. In the 1920s and 1930s, the increasing speed and altitude of airplanes necessitated a fully enclosed cockpit and canopies became more common. Early canopies were made of numerous pieces of flat glass held in position by a frame and muntins. The muntins reduced visibility, wh ...

Semi-monocoque
The term semi-monocoque or semimonocoque refers to a stressed shell structure that is similar to a true monocoque, but which derives at least some of its strength from conventional reinforcement. Semi-monocoque construction is used for, among other things, aircraft fuselages, car bodies and motorcycle frames. Examples of semi-monocoque vehicles Semi-monocoque aircraft fuselages differ from true monocoque construction through being reinforced with longitudinal stringers. The Mooney range of four seat aircraft, for instance, use a steel tube truss frame around the passenger compartment with monocoque behind. The British ARV Super2 light aircraft has a fuselage constructed mainly of aluminium alloy, but with some fibreglass elements. The cockpit is a stiff monocoque of "Supral" alloy, but aft of the cockpit bulkhead, the ARV is conventionally built, with frames, longerons and stressed skin forming a semi-monocoque."Pilot" magazine, June 1985 pages 5-6 Peter Williams' 1973 ...

Wing Loading
In aerodynamics, wing loading is the total mass of an aircraft or flying animal divided by the area of its wing. The stalling speed of an aircraft in straight, level flight is partly determined by its wing loading. An aircraft or animal with a low wing loading has a larger wing area relative to its mass, as compared to one with a high wing loading. The faster an aircraft flies, the more lift can be produced by each unit of wing area, so a smaller wing can carry the same mass in level flight. Consequently, faster aircraft generally have higher wing loadings than slower aircraft. This increased wing loading also increases takeoff and landing distances. A higher wing loading also decreases maneuverability. The same constraints apply to winged biological organisms. Range of wing loadings Effect on performance Wing loading is a useful measure of the stalling speed of an aircraft. Wings generate lift owing to the motion of air around the wing. Larger wings move more air, so an air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
