Static Model Aircraft
Static model airplanes are non-flying representations of aircraft that are designed primarily for display and educational purposes.(2016, February 19). "All You Need To Know About Static Model Aircraft." ''Scale Modellers Club''. These models are used in wind tunnel testing to gather data for the design of full-scale aircraft.Scott Mayerowitz, AP Airlines Writer (18 March 2015). "Airline world's tiny secret: infatuation with model planes". ''USA TODAY''. They are made in a wide array of sizes, ranging from miniature versions to those exceeding five feet in length. Some model aircraft are scaled to size. For example, a 1:40 scale that is 1/40th the size of the real aircraft. Static model aircraft are exhibited in places su ...

Focke-Wulf FW B 200 Condor
Focke-Wulf Flugzeugbau Aktiengesellschaft, AG () was a German manufacturer of civil and military aircraft before and during World War II. Many of the company's successful fighter aircraft designs were slight modifications of the Focke-Wulf Fw 190. It is one of the predecessor companies of today's Airbus. History The company was founded in Bremen (city), Bremen on 24 October 1923 as Bremer Flugzeugbau AG by Prof. Henrich Focke, Georg Wulf and Dr. rer. pol. Werner Naumann (businessman), Werner Naumann. Almost immediately, they renamed the company Focke-Wulf Flugzeugbau AG (later Focke-Wulf Flugzeugbau GmbH). Focke-Wulf merged, under Weimar Republic, government pressure, with Albatros Flugzeugwerke of Berlin in 1931. The Albatros Flugzeugwerke engineer and test pilot Kurt Tank became head of the technical department and started work on the Focke-Wulf Fw 44, Fw 44 ''Stieglitz'' (Goldfinch). Dr Ludwig Roselius became chairman in 1925 and handed over to his brother Friedrich in earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tweezers
Tweezers are small hand tools used for grasping objects too small to be easily handled with the human fingers. Tweezers are thumb-driven forceps most likely derived from tongs used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context, they are normally referred to as just "forceps", a name that is used together with other grasping surgical instruments that resemble pliers, pincer (tool), pincers and scissors-like clamp (tool), clamps. Tweezers make use of two third-class levers connected at one fixed end (the wikt:fulcrum, fulcrum point of each lever), with the pincers at the others. When used, they are commonly held with one hand in a pen grip between the thumb and index finger (sometimes also the middle finger), with the top end resting on the first dorsal interossei of the hand, dorsal interosseous muscle at the webspace between the thumb and index finger. Spring tension holds the grasping ends apart until finger pressure is applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Die-cast Toy
A die-cast toy (also spelled diecast, or die cast) is a toy or a collectible model produced by using the die casting, die-casting method of putting molten lead, zinc alloy or plastic in a mold to produce a particular shape. Such toys are made of metal, with plastic, rubber, glass, or other machined metal parts. Wholly plastic toys are made by a similar process of injection moulding, injection molding, but the two methods are distinct because of the properties of the materials. Process The metal used in die-casting is either a lead alloy (used early on), or more commonly, zamak (called ''Mazak'' in the UK), an alloy of zinc with small quantities of aluminium and copper. Lead or iron are impurities that must be carefully avoided in zamak, as they give rise to a deterioration of the metal most commonly called zinc pest. The terms white metal or pot metal are also used when applied to alloys based more on lead or iron. The most common die-cast vehicles are scale models of automobi ...

Digital Modeling And Fabrication
Digital modeling and fabrication is a design and production process that combines 3D modeling or computing-aided design (CAD) with additive and subtractive manufacturing. Additive manufacturing is also known as 3D printing, while subtractive manufacturing may also be referred to as machining, and many other technologies can be used to physically produce the designed objects. Modeling Digitally fabricated objects are created with a variety of CAD software packages, using both 2D vector drawing, and 3D modeling. Types of 3D models include wireframe, solid, surface and mesh. A design has one or more of these model types. Machines for fabrication Three machines are popular for fabrication: 1. CNC router 2. Laser cutter 3. 3D Printer CNC milling machine CNC stands for "computer numerical control". CNC mills or routers include proprietary software which interprets 2D vector drawings or 3D models and converts this information to a G-code, which represents specific CNC functions i ...

3D Printing
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. , the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology; in this context, the term ''additive manufacturing'' can be used synonymously with ''3D printing''. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise infeasi ...

Military Aircraft
A military aircraft is any Fixed-wing aircraft, fixed-wing or rotorcraft, rotary-wing aircraft that is operated by a legal or insurrectionary military of any type. Some military aircraft engage directly in aerial warfare, while others take on support roles: * Combat aircraft, such as Fighter aircraft, fighters and Bomber, bombers, are designed to destroy enemy equipment or personnel using their own aircraft ordnance, ordnance. Combat aircraft are typically developed and procured only by military forces. * Non-combat aircraft, such as military transport aircraft, transports and Tanker (aircraft), tankers, are not designed for combat as their primary function but may carry weapons for self-defense. These mainly operate in support roles, and may be developed by either military forces or civilian organizations. History Lighter-than-air In 1783, when the first practical aircraft (hot-air and hydrogen balloons) were established, they were quickly adopted for military duties. The ...

Sandpaper
upright=1.35, Sheets of sandpaper with different grit sizes (40 (coarse), 80, 150, 240, 600 (fine)) Sandpaper, also known as coated abrasive or emery paper, is a type of material that consists of sheets of paper or cloth with an abrasive substance glued to one face. In the modern manufacture of these products, sand and glass have been replaced by other abrasives such as aluminium oxide or silicon carbide. It is common to use the name of the abrasive when describing the paper, e.g. "aluminium oxide paper", or "silicon carbide paper". There are many varieties of sandpaper, with variations in the paper or backing, the material used for the grit, grit size, and the bond. Sandpaper is produced in a range of grit sizes and is used to remove material from surfaces, whether to make them smoother (for example, in painting and wood finishing), to remove a layer of material (such as old paint), or sometimes to make the surface rougher (for example, as a preparation for gluing). The grit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cement
A cement is a binder, a chemical substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel ( aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource. Cements used in construction are usually inorganic, often lime- or calcium silicate-based, and are either hydraulic or less commonly non-hydraulic, depending on the ability of the cement to set in the presence of water (see hydraulic and non-hydraulic lime plaster). Hydraulic cements (e.g., Portland cement) set and become adhesive through a chemical reaction between the dry ingredients and water. The chemical reaction results in mineral hydrates that are not very water-soluble. This allows setting in wet conditions or u ...

Side Cutters
Diagonal pliers (also known as wire cutters or diagonal cutting pliers, or under many regional names) are pliers intended for the cutting of wire or small stock, rather than grabbing or turning. The plane defined by the cutting edges of the jaws intersects the joint rivet at an angle or "on a diagonal", giving pliers their name. They are also adapted for use in inaccessible places. Action Instead of using a shearing action as with scissors, diagonal pliers cut by indenting and wedging the wire apart. The jaw edges are ground to a symmetrical " V" shape, thus the two jaws can be visualized to form the letter " X", as seen end-on when closed. The blades are made of tempered steel, and inductive heating and quenching are often used to harden the jaws. Jargon In UK English and Irish English, diagonal pliers are commonly referred to as snips, nippers or side cutters. The term snips commonly refers to larger items, not to those used for cutting electrical wiring etc. In Can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
