Gallaudet D-1
The Gallaudet D-1 was a prototype American biplane observation aircraft built by the Gallaudet Aircraft Company during World War I for the United States Navy. Completed in mid-1916, its manufacturer's flight testing was delayed by damage suffered during the tests, shortages of qualified pilots and the weather; the D-1 could not conduct its service flight testing until early 1917. The Navy found the aircraft only suitable for limited duties and operated it for several months before returning it to the factory later that year to have its deficiencies remedied. This was done, but the D-1 was never reassembled for unknown reasons and it was scrapped after the war. Background and description The D-1 was designed to meet a requirement for a two-seat, twin- float, twin-engined biplane for maritime-patrol duties issued by the United States Navy in February 1915. Edson Gallaudet, chief designer for the Gallaudet Aircraft Company, submitted a design on 4 June using his revolutionary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

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] |
Aircraft Flight Dynamics
Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as ''pitch'', ''roll'' and ''yaw''. These are collectively known as aircraft attitude, often principally relative to the atmospheric frame in normal flight, but also relative to terrain during takeoff or landing, or when operating at low elevation. The concept of attitude is not specific to fixed-wing aircraft, but also extends to rotary aircraft such as helicopters, and dirigibles, where the flight dynamics involved in establishing and controlling attitude are entirely different. Control systems adjust the orientation of a vehicle about its cg. A control system includes control surfaces which, when deflected, generate a moment (or couple from ailerons) about the cg which rotates the aircraft in pitch, roll, and yaw. For example, a pitching mom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in motor sports, with for example in Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may similarly be mounted on the rudder. Together, their role ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gallaudet Model C
Gallaudet University ( ) is a private university, private University charter#Federal, federally chartered research university in Washington, D.C. for the education of the Hearing loss, deaf and hard of hearing. It was founded in 1864 as a grammar school for both deaf and blind children. It was the first school for the advanced education of the deaf and hard of hearing in the world and remains the only higher education institution in which all programs and services are specifically designed to accommodate deaf and hard of hearing students. Hearing students are admitted to the graduate school and a small number are also admitted as undergraduates each year. The university was named after Thomas Hopkins Gallaudet, a notable figure in the advancement of deaf education. Gallaudet University is officially bilingual, with American Sign Language (ASL) and written English language, English used for instruction and by the college community. Although there are no specific ASL proficiency re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
