Ivoprop
Ivoprop Corporation, founded in 1984 by Ivo Zdarsky, is an American manufacturer of composite propellers for homebuilt and ultralight aircraft, as well as airboats. The company's headquarters are in Long Beach, California.Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook'', page 84. BAI Communications. Zdarsky started the company after carving his own propeller for a homebuilt ultralight trike that he flew to escape from Cold War Czechoslovakia, over the Iron Curtain to Vienna in 1984. Ivoprop has sold more than 20,000 propellers since then. The company's propellers are built from carbon-fiber-reinforced polymer and feature a stainless steel leading edge. Ivoprop variable-pitch propeller Ivoprop produce both in-flight adjustable and ground-adjustable propellers of unusual design. Whereas conventional variable-pitch propellers rotate at the blade root, the Ivoprop design has the blade root firmly clamped to the hub. The blade is hollow, containing a steel torsion rod f ...

Ground-adjustable Propeller
A ground-adjustable propeller is a simple type of aircraft variable-pitch propeller where the blade angle can be adjusted between pre-set limits of fine and coarse pitch.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 86. Aviation Supplies & Academics, 1997. As its name implies, a ground-adjustable propeller may be adjusted only when the aircraft is on the ground and when the engine is not running. Ground-adjustable propellers, which are mostly used on light and very light aircraft, are much cheaper and lighter than more sophisticated and versatile in-flight-adjustable propellers. A ground-adjustable propeller allows pitch changes to be made, although not in flight, to optimise the aircraft for current payload and flying conditions. Adjustment To adjust the propeller, the blades are loosened in the hub, a new angle set and then the hub tightened. The process is one of compromise, and of trial & error. After a flight, if, say, climb seemed too sluggish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ivo Zdarsky
Ivo is a masculine given name, in use in various European languages. The name used in western European languages originates as a Normannic name recorded since the High Middle Ages, and the French name Yves is a variant of it. The unrelated South Slavic name is a variant of the name Ivan (John). Origins The name is recorded from the High Middle Ages among the Normans of France and England ( Yvo of Chartres, born c. 1040). The name's etymology may be either Germanic or Celtic, in either case deriving from a given name with a first element meaning "yew" (Gaulish ''Ivo-'', Germanic ''Iwa-'').Campbell, MikIvo(Behind the Name: The Etymology and History of First Names) The name may have been spread by the cult of Saint Ivo (d. 1303), patron saint of Brittany. The Slavic name is a hypocorism, like its variant ''Ivica''. In Croatia, the name exhibits both Slavic and Celtic-Germanic origins; the Slavic variant Ivona of the Celtic-origin feminine name Yvonne, is regular and fairly ...

Carbon-fiber-reinforced Polymer
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers ( Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other ...

Manufacturing Companies Based In California
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final pro ...

Companies Based In Los Angeles County, California
A company, abbreviated as co., is a legal entity representing an association of legal people, whether natural, juridical or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Over time, companies have evolved to have the following features: "separate legal personality, limited liability, transferable shares, investor ownership, and a managerial hierarchy". The company, as an entity, was created by the state which granted the privilege of incorporation. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is to generate sales, revenue, and profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duties according to the publicly declared incorporatio ...

Bellflower, California
Bellflower is a city in southeastern Los Angeles County, California, in the Los Angeles metropolitan area. It was founded in 1906 and municipal corporation, incorporated on September 3, 1957. As of the 2020 United States census, 2020 census, the city had a total population of 79,190, up from 76,616 at the 2010 United States census, 2010 census. This made it the 65th List of United States cities by population density, most densely populated city in the United States, of cities over 50,000 residents (and the 8th most densely populated city in California). History The original title to the Bellflower area dates back to 1784 with one of the first Spanish land grants in California. The Bellflower area was a hunting and fishing spot due to an abundance of wild game, ducks and geese, carp and perch. The area was also used for cattle and grazing dairy cows but settlers moved away. Willow, bamboo, and underbrush, wild grape, blackberry, and rose bushes were grown along the river the name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerospace Companies Of The United States
Aerospace is a term used to collectively refer to the atmosphere and outer space. Aerospace activity is very diverse, with a multitude of commercial, industrial, and military applications. Aerospace engineering consists of aeronautics and astronautics. Aerospace organizations research, design, manufacture, operate, maintain, and repair both aircraft and spacecraft. The border between space and the atmosphere has been proposed as above the ground according to the physical explanation that the air density is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. This border has been called the Kármán line. Overview In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agen ...

Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Controllable Pitch Propeller
Controllability is an important property of a control system and plays a crucial role in many regulation problems, such as the stabilization of unstable systems using feedback, tracking problems, obtaining optimal control strategies, or, simply prescribing an input that has a desired effect on the state. Controllability and observability are dual notions. Controllability pertains to regulating the state by a choice of a suitable input, while observability pertains to being able to know the state by observing the output (assuming that the input is also being observed). Broadly speaking, the concept of controllability relates to the ability to steer a system around in its configuration space using only certain admissible manipulations. The exact definition varies depending on the framework or the type of models dealt with. The following are examples of variants of notions of controllability that have been introduced in the systems and control literature: * State controllability ...

Leading Edge
The leading edge is the part of the wing that first contacts the air;Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. alternatively it is the foremost edge of an airfoil section. The first is an aerodynamic definition, the second a structural one. As an example of the distinction, during a tailslide, from an aerodynamic point of view, the trailing edge becomes the leading edge and vice versa but from a structural point of view the leading edge remains unchanged. Overview The structural leading edge may be equipped with one or more of the following: * Leading edge boots * Leading edge cuffs * Leading edge extensions * Leading edge slats * Leading edge slots * Krueger flaps * Stall strips * Vortex generators. Associated terms are leading edge radius and leading edge stagnation point. Seen in plan the leading edge may be straight or curved. A straight leading edge may be swept or unswept, the latter meanin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
