Ray Stits
Raymond M. Stits (20 June 1921 - 8 June 2015) was an American inventor, homebuilt aircraft designer, aircraft mechanic and pilot. He designed the Stits SA-2A Sky Baby, which was the world's smallest aircraft in 1952, developed the Poly-Fiber aircraft fabric covering system and was the founder of Experimental Aircraft Association Chapter 1. David Gustafson, a Flabob Airport historian, wrote of Stits, "few people outside of the Poberezny family had as much influence on the early home built aircraft movement as Ray Stits." Life Stits served as an aircraft mechanic in the United States Army Air Forces during the Second World War. He served in the mainland US, with distinction. In 1953, Stits convinced Experimental Aircraft Association founder Paul Poberezny that local chapters would benefit the homebuit aircraft movement and founded Chapter 1 at Flabob Airport in Rubidoux, California. As the result of a flash-burn accident while burning some scrap aircraft fabric, he desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stits SA-2A Sky Baby
The Stits SA-2A Sky Baby was a homebuilt aircraft designed for the challenge of claiming the title of "The World's Smallest". Design and development The Sky Baby was designed by Ray Stits and built with Robert H. Starr as a follow-on to the Stits Junior midget racer. The aircraft is an enclosed single engine negative staggered cantilevered biplane with conventional landing gear. The fuselage is constructed of welded steel tubing with aircraft fabric covering. The upper wings have Flap (aircraft), flaps, the lower wings have ailerons. Most aircraft use a flat firewall between the engine and pilot's feet, the Skybaby is configured with the pilot sitting with the engine close to the lap, and rudder pedals located under the oil sump toward the front of the cowling. The powerplant was sourced from an ERCO Ercoupe, modified with water injection to produce . Operational history The aircraft was test flown by Robert H. Starr on 26 May 1952 at Palm Springs, California. The short couple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the Writing system#Directionality, directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Glossary of mathematical sym ...

Empire State Aerosciences Museum - Glenville, New York (8158375346)
An empire is a "political unit" made up of several territories and peoples, "usually created by conquest, and divided between a dominant center and subordinate peripheries". The center of the empire (sometimes referred to as the metropole) exercises political control over the peripheries. Within an empire, there is non-equivalence between different populations who have different sets of rights and are governed differently. Narrowly defined, an empire is a sovereign state whose head of state is an emperor; but not all states with aggregate territory under the rule of supreme authorities are called empires or ruled by an emperor; nor have all self-described empires been accepted as such by contemporaries and historians (the Central African Empire, and some Anglo-Saxon kingdoms in early England being examples). There have been "ancient and modern, centralized and decentralized, ultra-brutal and relatively benign" Empires. An important distinction has been between land empires m ...

Vietnam War
The Vietnam War (also known by #Names, other names) was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. The north was supported by the Soviet Union, China, and other communist states, while the south was United States in the Vietnam War, supported by the United States and other anti-communism, anti-communist Free World Military Forces, allies. The war is widely considered to be a Cold War-era proxy war. It lasted almost 20 years, with direct U.S. involvement ending in 1973. The conflict also spilled over into neighboring states, exacerbating the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist states by 1975. After the French 1954 Geneva Conference, military withdrawal from Indochina in 1954 – following their defeat in the First Indochina War – the Viet Minh to ...

Jurupa Valley, California
Jurupa Valley ( Serrano: ''Hurumpa'') is a city in the northwest corner of Riverside County, California. It was the location of one of the earliest non-native settlements in the county, Rancho Jurupa. The Rancho was initially an outpost of the Mission San Gabriel Arcángel, then a Mexican land grant in 1838. The name is derived from a Native American village that existed in the area prior to the arrival of Europeans. On March 8, 2011, voters approved a ballot measure, Measure A, to incorporate and form the city of ''Jurupa Valley''. The effective date of incorporation was July 1, 2011. Residents of the area had previously voted on incorporation in 1992, but rejected that measure, along with a competing ballot measure that would have incorporated Mira Loma.

Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyurethane
Polyurethane (; often abbreviated PUR and PU) refers to a class of polymers composed of organic chemistry, organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials. This chemical variety produces polyurethanes with different chemical structures leading to many List of polyurethane applications, different applications. These include rigid and flexible foams, varnishes and coatings, adhesives, Potting (electronics), electrical potting compounds, and fibers such as spandex and Polyurethane laminate, PUL. Foams are the largest application accounting for 67% of all polyurethane produced in 2016. A polyurethane is typically produced by reacting an isocyanate with a polyol. Since a polyurethane contains two types of monomers, which polymerize one after the other, they are classed as Copolymer#Alternating copolymers, alternating copolymers. Both the isocy ...

Aircraft Dope
Aircraft dope is a plasticised lacquer that is applied to fabric-covered aircraft. It tightens and stiffens fabric stretched over airframes, which renders them airtight and weatherproof, increasing their durability and lifespan.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 170. Aviation Supplies & Academics, 1997. The technique has been commonly applied to both full-size and flying models of aircraft. Attributes Doping techniques have been employed in aircraft construction since the dawn of heavier-than-air flight; the fabric of the ground-breaking Wright Flyer had benefitted from doping, as did many of the aircraft that soon followed. Without the application of dope, fabric coverings lacked durability while being highly flammable, both factors rendering them far less viable. By the 1910s, a wide variety of doping agents had entered widespread use while entirely original formulas were being regularly introduced in the industry. Typical doping agents in ...

Cotton
Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus ''Gossypium'' in the mallow family Malvaceae. The fiber is almost pure cellulose, and can contain minor percentages of waxes, fats, pectins, and water. Under natural conditions, the cotton bolls will increase the dispersal of the seeds. The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds. The fiber is most often spun into yarn or thread and used to make a soft, breathable, and durable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley civilization, as well as fabric remnants dated back ...
