El Cajon, California
El Cajon ( , ; Spanish: El Cajón, meaning "the box") is a city in San Diego County, California, United States, east of downtown San Diego. The city takes its name from Rancho El Cajón, which was in turn named for the box-like shape of the valley that surrounds the city, which is also the origin of the city's common nickname of "the Box".El Cajon city history Name 
''El Cajón,'' Spanish for "the box", was first recorded on September 10, 1821, as an alternative name for ''sitio rancho Santa Mónica'' to describe the "boxed-in" nature of the valley in which it sat. The name appeared on maps in 187 ...

Aerospace
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 ...

Propeller (aircraft)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homebuilt Aircraft
Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch", from plans, or from assembly kits.Armstrong, Kenneth: ''Choosing Your Homebuilt - the one you will finish and fly! Second Edition'', pp. 39–52. Butterfield Press, 1993. Peter M Bowers: ''Guide to Homebuilts - Ninth Edition''. TAB Books, Blue Ridge Summit PA, 1984. Overview In the United States, Brazil, Australia, New Zealand and South Africa, homebuilt aircraft may be licensed Experimental under FAA or similar local regulations. With some limitations, the builder(s) of the aircraft must have done it for their own education and recreation rather than for profit. In the U.S., the primary builder can also apply for a repairman's certificate for that airframe. The repairman's certificate allows the holder to perform and sign off on most of the maintenance, repairs, and inspections themsel ...

Light-sport Aircraft
A light-sport aircraft (LSA), or light sport aircraft, is a fairly new category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight (aka "microlight") aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA . LSAs in different countries The civil aviation authorities in different countries have their own particular specifications and regulations which define the LSA category. For example, in Australia the Civil Aviation Safety Authority defines a light-sport aircraft as a heavier-than-air or lighter-than-air craft, other than a helicopter, with a maximum gross takeoff weight of not more than for lighter-than-air craft; for heavier-than-air craft not intended for operation on water; or for aircraft intended for operation on water. It must have a maximum stall speed of in landing configuration; a maximum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nanchang CJ-6
The Nanchang CJ-6 () is a Chinese basic trainer aircraft designed and built by the Nanchang Aircraft Factory (now Hongdu Aviation) for use by the People's Liberation Army Air Force (PLAAF). Development The CJ-6 (Chu Jiao 初教 = Chuji Jiaolianji 初级教练机 = basic trainer aircraft) is an all-original Chinese design that is commonly mistaken for a Yak-18A. Its predecessor, the Nanchang CJ-5, was a licence-built version of the Yak-18. However, advancements in pilot training brought a need for a new aircraft with improved performance and a tricycle landing gear. When the Soviet Union developed the Yak-18A, PLAAF engineers decided that its performance and design would not suit China's needs. The aircraft was designed in 1958 by the Nanchang Aircraft Factory (now Hongdu Aviation). As the Shenyang Aircraft Factory already had experience building the Shenyang JJ-1 begun technical research for the CJ-6, more than 20 Shenyang designers were transferred to Nanchang, including ...

Airboat
An airboat (also known as a planeboat, swamp boat, bayou boat, or fanboat) is a flat-bottomed watercraft propelled by an aircraft-type propeller and powered by either an aircraft or automotive engine. In early aviation history the term ''airboat'' was applied to seaplanes or flying boats, i.e. aircraft capable of taking off and landing on water surfaces. Early airboats were known as "hydroglisseurs" (airboat in French, "water slider"), hydroplanes, hydrofoils, or other names. See e.g. ''Flying'Volume 4(1915-1916) and Cercle du Mononautisme Classiqu (in French). They are commonly used for fishing, bowfishing, hunting, and ecotourism. Airboats are a common means of transportation in marshy and/or shallow areas where a standard inboard or outboard engine with a submerged propeller would be impractical, most notably in the Florida Everglades but also in the Kissimmee and St. Johns rivers, and the Mekong River and Delta, as well as the Louisiana bayous and Mesopotamian Marshes. ...

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 ...
