Thomas Moy
Thomas William Moy (1823–1910) was an English engineer and patent agent best known for his ''Aerial Steamer'' of 1875. Early life Moy was born in the Liberty of the Rolls (now part of Westminster) in London around 1823. In the 1851 census of Islington he is listed as living with his wife Henrietta and six-month-old daughter and is described as a 28-year-old law stationers clerk. 1851 Census of Islington, RG8/1500, Folio 415, Page 6, Thomas Moy, 15 Freeling Street, Finsbury. In 1881 Moy was living in Camberwell and was described as a 58-year-old civil engineer. 1881 Census of Camberwell, RG11/676, Folio 66, Page 35, Thomas Moy, 64 Anstley Road, Camberwell. In 1901 he was still living in Camberwell but was now described as a 78-year-old mechanical engineer and patentee; his wife also with him, but she died a few months after the census. 1901 Census of Camberwell, RG13/508, Folio 65, Page 13, Thomas Moy, 130 Ivydale Road, Camberwell.

Liberty Of The Rolls
The Liberty of the Rolls was a liberty, and civil parish, in the metropolitan area of London, England. The Liberty was probably created in the late medieval period by its removal from the Farringdon Without Ward of City of London,London 800-1216: The shaping of a city, Brooke and Keir, Chapter 7 and consisted of the part of the ancient parish of St Dunstan-in-the-West that was in the Ossulstone hundred of Middlesex, the rest of the parish was within the City. It became a separate civil parish in 1866. Named perhaps after the ancient Rolls House upon Chancery Lane where the rolls of the Court of Chancery of England were kept, or perhaps, like other parishes, the chapel. The site of the house and chapel became the nucleus of the Public Record Office, now the Maughan Library and Provost's Lodgings of King's College London. It was grouped into the Strand District in 1855 when it came within the area of responsibility of the Metropolitan Board of Works. It was a civil parish from ...

Tandem Wing
QAC Quickie Q2 A tandem wing is a wing configuration in which a flying craft or animal has two or more sets of wings set one behind another. All the wings contribute to lift. The tandem wing is distinct from the biplane in which the wings are stacked one above another, or from the canard or "tail-first" configuration where the forward surface is much smaller and does not contribute significantly to the overall lift. In aviation, tandem wings have long been experimented with, but few designs have ever been put into production. Tandem wings in nature occur only in insects and flying fish, although in the past there have been tandem-wing flying reptiles. Design principles A tandem wing configuration has two main wing planes, with one located forward and the other to the rear. The difference is greater than the wing chord, so there is a clear gap between them and the aircraft centre of gravity (CG) lies between the wings.Bottomley (1977) Compared to the conventional layout, whe ...

Alphonse Pénaud
Alphonse Pénaud (31 May 1850 – 22 October 1880), was a 19th-century French pioneer of aviation design and engineering. He was the originator of the use of twisted rubber to power model aircraft, and his 1871 model airplane, which he called the ''Planophore'', was the first aerodynamically stable flying model. He went on to design a full-sized aircraft with many advanced features, but was unable to get any support for the project, and eventually committed suicide in 1880, aged 30. Biography Pénaud was born in Paris into a naval family, his father Charles Pénaud being an admiral in the French Navy. Because of a hip disease he walked with the aid of crutches and so was unable to attend the Naval School. At 20, he began studying aviation and joined the newly-founded ''Société Aéronautique de France''. He became vice-president of the Society in 1876 and participated in the publication of the journal ''L'Aéronaute''. In 1870, Pénaud made the first of a series of succe ...

Angle Of Incidence (aerodynamics)
On fixed-wing aircraft, the angle of incidence (sometimes referred to as the ''mounting angle'' or ''setting angle'') is the angle between the chord line of the wing where the wing is mounted to the fuselage, and a reference axis along the fuselage (often the direction of minimum drag, or where applicable, the longitudinal axis). The angle of incidence is fixed in the design of the aircraft, and with rare exceptions, cannot be varied in flight. The term can also be applied to horizontal surfaces in general (such as canards or horizontal stabilizers) for the angle they make relative the longitudinal axis of the fuselage. The figure to the right shows a side view of an airplane. The extended chord line of the wing root (red line) makes an angle with the longitudinal axis (roll axis) of the aircraft (blue line). Wings are typically mounted at a small positive angle of incidence, to allow the fuselage to have a low angle with the airflow in cruising flight. Angles of incidence ...

Dihedral (aircraft)
Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It is the angle between the zero-lift axis of the wing and the zero-lift axis of the horizontal tail. Longitudinal dihedral can influence the nature of controllability about the pitch axis and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambric
Cambric or batiste is a fine dense cloth. It is a lightweight plain-weave fabric, originally from the commune of Cambrai (in present-day northern France), woven greige (neither bleached nor dyed), then bleached, piece-dyed, and often glazed or calendered. Initially it was made of linen; from the 18th and 19th centuries the term came to apply to cotton fabrics as well. Chambray is a similar fabric, with a coloured (often blue or grey) warp and white filling; the name "chambray" replaced "cambric" in the United States in the early 19th century. Cambric is used as fabric for linens, shirts, handkerchiefs, ruffs, lace, and in cutwork and other needlework. Dyed black, it is also commonly used as the dustcover on the underside of upholstered furniture. Description Cambric is a finely woven cloth with a plain weave and a smooth surface appearance, the result of the calendering process. It may be made of linen or cotton. The fabric may be dyed any of many colours. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Blade Pitch
Blade pitch or simply pitch refers to the angle of a blade in a fluid. The term has applications in aeronautics, shipping, and other fields. Aeronautics In aeronautics, blade pitch refers to the angle of the blades of an aircraft propeller or helicopter rotor. Blade pitch is measured relative to the aircraft body. It is usually described as "fine" or "low" for a more vertical blade angle, and "coarse" or "high" for a more horizontal blade angle. Blade pitch is normally described as a ratio of forward distance per rotation assuming no slip. Blade pitch acts much like the gearing of the final drive of a car. Low pitch yields good low speed acceleration (and climb rate in an aircraft) while high pitch optimizes high speed performance and fuel economy. It is quite common for an aircraft to be designed with a variable-pitch propeller, to give maximum thrust over a larger speed range. A fine pitch would be used during take-off and landing, whereas a coarser pitch is used for high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aircraft Flight Control System
A conventional Fixed-wing aircraft, fixed-wing aircraft flight control system (AFCS) consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered flight controls as they change speed. The fundamentals of aircraft controls are explained in flight dynamics (fixed-wing aircraft), flight dynamics. This article centers on the operating mechanisms of the flight controls. The basic system in use on aircraft first appeared in a readily recognizable form as early as April 1908, on Louis Blériot's Blériot VIII pioneer-era monoplane design. Cockpit controls Primary controls Generally, the primary cockpit flight controls are arranged as follows:Langewiesche, WolfgangStick and Rudder: An Explanation of the Art of Flying McGraw-Hill Professional, 1990, , . * A Yoke (aircraft), control yoke (also known as a control column), cen ...

Linen
Linen () is a textile made from the fibers of the flax plant. Linen is very strong and absorbent, and it dries faster than cotton. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. Linen textiles can be made from flax plant fiber, yarn, as well as woven and knitted. Linen also has other distinctive characteristics, such as its tendency to wrinkle. It takes significantly longer to harvest than a material like cotton, although both are natural fibers. It is also more difficult to weave than cotton. Linen textiles appear to be some of the oldest in the world; their history goes back many thousands of years. Dyed flax fibers found in a cave in the Caucasus (present-day Georgia (country), Georgia) suggest the use of woven linen fabrics from wild flax may date back over 30,000 years. Linen was used in ancient civilizations including Mesopotamia and ancient Egypt, and linen is mentioned in the Bible. In the 18th century and be ...
