Windecker Eagle
The Eagle AC-7 Eagle 1 (USAF designation YE-5) is an aircraft that was manufactured by Windecker Industries. It was the first composite airplane (foam and fiberglass construction) to receive FAA certification in December 1969 at a reported development cost of US$20,000,000. The fiberglass process was named "Fibaloy" by Windecker. Design and development The Eagle's fuselage was molded in two pieces that were joined down the middle. The first prototype had a fixed undercarriage but the second, known as the Eagle 1, had retractable tricycle gear. This aircraft first flew on 26 January 1969. One prototype spun in on testing. Only eight Eagles were produced before production ended when the company ran out of money. No Eagle had been flying for many years, but one was restored and flown in December 2015, by Don Atchison, Mike Moore and a team commissioned by Chinese entrepreneur Wei Hang. Wei Hang holds the rights and the type certificate and plans to produce the aircraft in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lone Star Flight Museum
The Lone Star Flight Museum, located in Houston, Texas, is an aerospace museum that displays more than 24 historically significant aircraft, and many artifacts related to the history of flight. The museum's collection is rare because most of the aircraft are flyable. Located at Ellington Airport, the museum is housed on about 100,000 ft2 (10,000 m2) of property, including its own airport ramp. The museum, formerly located in Galveston, moved to Houston to avoid a repeat of the devastation suffered during Hurricane Ike. History The museum began as a private collection of historic aircraft in 1985. By 1990, that collection had grown enough that its owner decided to place them on public display. The Lone Star Flight Museum, a non-profit organization funded entirely through private donations, was formed for that purpose. 2008 damage and restoration The museum reported heavy damage from Hurricane Ike, stating on September 16, 2008, that the hangars and Hall of Fame had rec ...

Windecker Industries
Windecker Industries was an American aircraft manufacturer founded in 1962 in aviation, 1962 as Windecker Research in Midland, Texas, by Leo Windecker, a Dentistry, dentist from Lake Jackson, Texas. In 1969, Windecker won Federal Aviation Administration (FAA) certification for the first-ever all-composite (fiberglass epoxy resin) airplane, the single-engine Windecker Eagle. Early flight testing Initial tests of composite wings on conventional airplane bodies began in 1958. Full FAA-supervised structural and flight testing began in 1961. In 1965, the company delivered a pair of composite wings to Cessna Aircraft Company, where they were subjected to structural and flight testing on a Cessna 182. Results proved promising, so the company built an experimental prototype of all-composite aircraft, the Windecker Eagle, Windecker ACX-7 Eagle. Designed by Dr. Leo Windecker and his wife, Dr. Fairfax Windecker (also a dentist), the aircraft was molded from a unidirectional fiberglass called ...

Windecker YE-5
The Windecker YE-5A was an experimental aircraft evaluated by the U.S. Air Force. It was an all-composite construction aircraft, based on the commercial single-engine, low-wing Windecker Eagle. The YE-5A, delivered in 1973, was used in tests relating to the radar detectability (commonly known as ' stealth') of composite aircraft. A single YE-5A (serial number 73-1653) was built. The YE-5A composite airframe benefited from the U.S. Army project and was shown to be difficult to detect using radar; however other components, including the metal engine, could be seen on radar. The YE-5A was destroyed in a crash during a classified project in 1985, and was replaced by a modified conventional civilian model Windecker Eagle (N4196G), to complete the project. This aircraft is disassembled and in storage in the United States Army Aviation Museum at Fort Rucker, Alabama. Project CADDO The U.S. Air Force tests were preceded by tests of a nearly similar prototype, which was delivered to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuselage
The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft the single engine is mounted on a pylon attached to the fuselage, which in turn is used as a floating hull. The fuselage also serves to position the control and stabilization surfaces in specific relationships to lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight stringers, allowing the fabric covering to form a more aerodynamic shape, or one more pleasing to the eye. Geodesic construction Geo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tricycle Gear
Tricycle gear is a type of aircraft undercarriage, or ''landing gear'', arranged in a tricycle fashion. The tricycle arrangement has a single nose wheel in the front, and two or more main wheels slightly aft of the center of gravity. Tricycle gear aircraft are the easiest for takeoff, landing and taxiing, and consequently the configuration is the most widely used on aircraft.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', page 524. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', page 11 (27th revised edition) History Several early aircraft had primitive tricycle gear, notably very early Antoinette planes and the Curtiss Pushers of the pre-World War I Pioneer Era of aviation. Waldo Waterman's 1929 tailless '' Whatsit'' was one of the first to have a steerable nose wheel. In 1956, Cessna introduced sprung-steel tricycle landing gear on the Cessna 172. Their marketing department described this as "Land-O-Matic" t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Certificate
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, primary category aircraft, certification costs around US$1m, US$25m for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes. The TC reflects a determination made by a regulatory authority that the type desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Aviation Week & Space Technology
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Continental IO-520C
The Continental O-520 is a six-cylinder, horizontally opposed aircraft engine produced by Teledyne Continental Motors. First run in 1963 as a development of the IO-346, it has been produced in versions incorporating fuel injection (IO-520), turbo-charging (TSIO-520), and gearing (GTSIO-520). Design and development The IO-520 series engines normally produce and are used in numerous aircraft such as certain models of the Bellanca Viking 300 and Super Viking, the Beech Bonanza and Baron, and Cessna 185- 206-, 210-, 310-, and 400-series aircraft. The IO-520 remained in production in 2019. The turbocharged GTSIO-520's most common applications are the twin-engine Cessna 404 and 421, where it is rated at .

Flat-six
A flat-six engine, also known as a horizontally opposed-six, is a six-cylinder piston engine with three cylinders on each side of a central crankshaft. The most common type of flat-six engine is the boxer-six engine, where each pair of opposed cylinders moves inwards and outwards at the same time. The advantages of the flat-six layout are good engine balance (for reduced vibration), a low center of gravity, short length (compared with an inline-six engine) and being well suited to air-cooling. The disadvantages are a large width (which can limit the maximum steering angle when used in a front-engined car), a large intake manifold being required when a central carburetor is used, and duplication of the inlet and outlet connections for water-cooled engines. The first production flat-six engine was in the 1904 ''Wilson-Pilcher 18/24 HP'' car. The most notable use of flat-six engines is the Porsche 911 sports car, which has used flat-six engines continuously since 1963. Several ot ...

Constant-speed Propeller
In aeronautics, a variable-pitch propeller is a type of propeller (airscrew) with blades that can be rotated around their long axis to change the blade pitch. A controllable-pitch propeller is one where the pitch is controlled manually by the pilot. Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed ( RPM), and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. Some aircraft have ground-adjustable propellers, however these are not considered variable-pitch. These are typically found only on light aircraft and microlights. Purpose When an aircraft is ...
