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 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 The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305.

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. To adjust the propeller, the blades are loosened in the hub, a new angle set and then the hub tightened. Ground-adjustable propellers, which tend to be found on light aircraft and very light aircraft, are much cheaper and lighter in weight than in-flight-adjustable propellers. Although a ground-adjustable propeller is much less versatile than an in-flight-adjustable equivalent, nevertheless, compared to a fixed pitch propeller, a ground-adjustable propeller means that pitch changes can be made on the ground to optimise the aircraft for current payload and fly ...

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''. Variations Ivo has the genitive form of "Ives" in the place name St Ives. In France, the usual variation of the name is Yves. In the Hispanic countries of La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 addit ...

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 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 product. ...

Bellflower, California
Bellflower is a city located in southeast 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 census, the city had a total population of 79,190, up from 76,616 at the 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). The site was formerly rich farmland watered by artesian wells and floodwaters of the now-contained San Gabriel River (California), San Gabriel River. In 1906, F.E. Woodruff, a local real estate investor, founded the first municipality on the site, which was named Somerset in 1909 when a post office was established there. However, the proponents of the name 'Bellflower' claimed that the US Post Office Department rejected the name 'Somerset' to prevent confusion with Somerset, Col ...

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, or maintain both aircraft and spacecraft. The beginning of space and the ending of the air is considered as 100 km (62 mi) above the ground according to the physical explanation that the air pressure is too low for a lifting body to generate meaningful lift force without exceeding orbital velocity. Overview In most industrial countries, the aerospace industry is a cooperation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as NASA, National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Re ...

Aircraft Propeller Manufacturers
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ball ...

Propeller
A propeller (colloquially 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 specially 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 sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Controllable Pitch Propeller
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leading Edge
The leading edge of an airfoil surface such as a wing is its foremost edge and is therefore the part which first meets the oncoming air.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 305. Aviation Supplies & Academics, 1997. Characteristics Sweep Seen in plan the leading edge may be straight, curved, kinked or a combination of these. A straight leading edge may be swept or unswept, while curves or kinks always mean that part of the leading edge is swept. On a swept wing the sweep angle may differ from that of the wing, as wing sweep is conventionally measured at the airfoil 25% chord line. However on a delta wing the leading edge sweep defines the wing sweep. Radius and stagnation point A rounded leading edge helps to maintain a smooth airflow at varying angles of incidence to the airflow. Most subsonic airfoils therefore have a rounded leading edge. The degree of rounding is characterised by the profile radius at that point. The airflow divides to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
