Horizontal Stabilizer
A tailplane, also known as a horizontal stabilizer, is a small lifting surface located on the tail ( empennage) behind the main lifting surfaces of a fixed-wing aircraft as well as other non-fixed-wing aircraft such as helicopters and gyroplanes. Not all fixed-wing aircraft have tailplanes. Canards, tailless and flying wing aircraft have no separate tailplane, while in V-tail aircraft the vertical stabilizer, rudder, and the tail-plane and elevator are combined to form two diagonal surfaces in a V layout. The function of the tailplane is to provide stability and control. In particular, the tailplane helps adjust for changes in position of the centre of pressure or centre of gravity caused by changes in speed and attitude, fuel consumption, or dropping cargo or payload. Tailplane types The tailplane comprises the tail-mounted fixed horizontal stabilizer and movable elevator. Besides its planform, it is characterised by: *Number of tailplanes - from 0 ( tailless or canard) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empennage Components FAA GFH
The empennage ( or ), also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb which means "Fletching, to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of Yaw (rotation), yaw and pitch (flight), pitch, as well as housing flight control surface, control surfaces. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (su ...

Roe I Triplane
The Roe I Triplane (often later referred to as the Avro Triplane) was an early aircraft designed and built by Alliot Verdon Roe, A.V. Roe which was the first all-British aircraft to fly.Jackson 1990 p.6 (Roe's Roe I Biplane, previous biplane had a French engine). Background After being evicted from Brooklands, where he had worked on his first aircraft, Roe started work in July 1908 on the design of a triplane: a patent was filed for this design in January 1909,Jackson 1990 p.4 and work was started on the construction of an aircraft of this design in the stable adjoining the house of his brother, Dr Spencer Verdon Roe, in Putney in South-West London. It was then transported to the new flying ground that Roe had found on Walthamstow Marshes (then in Essex, but now within the London Borough of Waltham Forest), where he rented two railway arches under the LNER railway besides the river Lea. Design and development The Roe I Triplane was a two-bay triplane: the tailplane, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tail Plane Flying
The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso. In vertebrate animals that evolved to lose their tails (e.g. frogs and hominid primates), the coccyx is the homologous vestigial of the tail. While tails are primarily considered a feature of vertebrates, some invertebrates such as scorpions and springtails, as well as snails and slugs, have tail-like appendages that are also referred to as tails. Tail-shaped objects are sometimes referred to as "caudate" (e.g. caudate lobe, caudate nucleus), and the body part associated with or proximal to the tail are given the adjective " caudal" (which is considered a more precise anatomical terminology). Function Animal tails are used in a variety of ways. They provide a source of thrust for aquatic locomotion for fish, cetaceans and crocodilians and other forms of marine life.

Boeing 727
The Boeing 727 is an American Narrow-body aircraft, narrow-body airliner that was developed and produced by Boeing Commercial Airplanes. After the heavier Boeing 707, 707 quad-jet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out on November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. The only trijet aircraft to be produced by Boeing, the 727 is powered by three Pratt & Whitney JT8D Turbofan, low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct below the tail. It shares its six-abreast upper fuselage cross-section and cockpit with the 707 that was also later used on the Boeing 737, 737. The 727-100 typically carries 106 passengers in two classes over , or 129 in a single class. La ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gloster Javelin
The Gloster Javelin is a twin-engined all-weather interceptor aircraft designed and produced by the Gloster Aircraft Company. It was operated by the Royal Air Force from the mid-1950s until the late 1960s and was the final aircraft design to bear the Gloster name. The Javelin was designed in response to specification F.44/46 during the late 1940s and early 1950s as high-performance night fighter capable of all-weather operations. In terms of its basic configuration, it was a T-tailed delta-wing aircraft powered by a pair of Armstrong Siddeley Sapphire turbojet engines. Following a protracted development period, the Javelin was introduced to squadron service during 1956. Throughout its service life, the aircraft received several upgrades, which were typically focused upon its engines, radar and weapons, including support for the De Havilland Firestreak air-to-air missile. The Javelin was succeeded in the interceptor role by the English Electric Lightning, a supersonic air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-tail
A T-tail is an empennage wikt:configuration, configuration in which the tailplane of an aircraft is mounted to the top of the vertical stabilizer, fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a Wing_configuration#Number_and_position_of_main_planes, high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sud Aviation Caravelle
The Sud Aviation SE 210 Caravelle is a French jet airliner produced by Sud Aviation. It was developed by SNCASE in the early 1950s, and made its maiden flight on May 27, 1955. It included some de Havilland designs and components developed for the de Havilland Comet, the first jet airliner. SNCASE merged into the larger Sud Aviation conglomerate before the aircraft entered revenue service on April 26, 1959, with Scandinavian Airlines System (SAS); 282 were built until production ended in 1972. It was ordered by airlines on every continent and operated until its retirement in 2005. The short-range, five-abreast airliner is powered by two aft-mounted Rolls-Royce Avon turbojet engines, allowing a clean low wing. The configuration was later retained in many narrow-body aircraft and regional jets. The initial I, III and VI variants could seat 90 to 99 passengers over . The later, slightly longer 10/11 variants could seat 99 to 118 passengers over and were powered by Pratt & Whitn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Sea Hawk
The Hawker Sea Hawk is a British single-seat jet day fighter formerly of the Fleet Air Arm (FAA), the air branch of the Royal Navy (RN), built by Hawker Aircraft and its sister company, Armstrong Whitworth Aircraft. Although its design originated from earlier Hawker piston-engined fighters, the Sea Hawk was the company's first jet aircraft. Following acceptance in the RN, the Sea Hawk proved to be a reliable and sturdy workhorse. A considerable number were also produced for the export market and were operated from aircraft carriers in Dutch and Indian service. The last operational Sea Hawks, operated by the Indian Navy, were retired in 1983. Design and development Origins Towards the end of the Second World War, Hawker's design team had become increasingly interested in developing a fighter aircraft that took advantage of the newly developed jet propulsion technology. Prior to this, Hawker had been committed until late 1944 to the production and further development of its pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruciform Tail
The cruciform tail is an aircraft empennage configuration which, when viewed from the aircraft's front or rear, looks much like a cross. The usual arrangement is to have the tailplane, horizontal stabilizer intersect the vertical tail somewhere near the middle, and above the top of the fuselage. The design is often used to locate the horizontal stabilizer away from jet exhaust, propeller and wing wake, as well as to provide undisturbed airflow to the rudder. Prominent examples of aircraft with cruciform tails include the Avro Canada CF-100 Canuck, the British Aerospace Jetstream 31, the MiG-15, the Fairchild Swearingen Metroliner, and the Rockwell B-1 Lancer.
