Fairchild 228
The Fairchild 228 was a regional jet developed for the United States market by Fairchild Hiller using Fokker F28 sub-assemblies. Design and development In 1967 Fairchild-Hiller sought to develop their own regional jet, the FH-327. Fairchild elected to leverage their relationship with Fokker aircraft in building F.27 aircraft, with a similar arrangement. The plan was to purchase sub-assemblies for the then new F.28 regional jet and assemble them in America into a shortened configuration aircraft with different engines. The Fairchild 228 was to be a 50-passenger twin-engine turbofan regional aircraft. The engines were mounted on the rear of the fuselage, with a swept T-tail arrangement. The wings were equipped with triple-slotted flaps for short-field operations. A new thrust Rolls-Royce RB.203 Trent turbofan was selected to power the aircraft. Fairchild estimated orders of 260-460 aircraft for the US market and 600-800 Internationally. The first sub-assemblies were shipped t ...

Regional Airliner
A regional airliner or a feederliner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feederliner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines: even the De Havilland Dragon Rapide biplane, or the Douglas DC-3s, in large surplus after the war, which the Aircraft manufacturers wanted t ...

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

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] |
West Coast Airlines
West Coast Airlines was an airline (then called a "local service" airline as defined by the federal Civil Aeronautics Board) linking small cities in the Pacific Northwest with larger cities in Washington, Oregon, Idaho, Utah, Montana, California and north to Alberta in Canada. It was headquartered in the Westlake area of Seattle, Washington. History West Coast was formed in 1941 and acquired Empire Air Lines (formerly Zimmerly Airlines) in 1952. The company was based at Boeing Field in Seattle and began scheduled passenger service in 1946 with a fleet of Douglas DC-3s, marketed as ''Scenicliners''. A promotional film produced for the company in the 1960s said that in 1946 the federal Civil Aeronautics Board (CAB) granted the first regional airline certificate to West Coast Airlines as local service air carrier. In July 1953, West Coast scheduled flights to 32 airports in Washington, Oregon, and Idaho; in May 1968 it flew to 36 airports including 29 in those states. Like other L ...

Hagerstown, Maryland
Hagerstown is a city in Washington County, Maryland, United States and the county seat of Washington County. The population of Hagerstown city proper at the 2020 census was 43,527, and the population of the Hagerstown metropolitan area (extending into West Virginia) was 269,140. Hagerstown ranks as Maryland's sixth-largest incorporated city and is the largest city in the Panhandle. Hagerstown has a distinct topography, formed by stone ridges running from northeast to southwest through the center of town. Geography accordingly bounds its neighborhoods. These ridges consist of upper Stonehenge limestone. Many of the older buildings were built from this stone, which is easily quarried and dressed onsite. It whitens in weathering and the edgewise conglomerate and wavy laminae become distinctly visible, giving a handsome and uniquely "Cumberland Valley" appearance. Several of Hagerstown's churches are constructed of Stonehenge limestone. Its value and beauty as building rock may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-tail
A T-tail is an empennage configuration in which the tailplane is mounted to the top of the 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 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 Avro RJ-85. The disturbed airflow over a lower stabilizer can make control more difficult at lower speeds. Dur ...

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.

Fokker F27 Friendship
The Fokker F27 Friendship is a turboprop airliner developed and manufactured by the Dutch aircraft manufacturer Fokker. It is the most numerous post-war aircraft manufactured in the Netherlands; the F27 was also one of the most successful European airliners of its era. The F27 was developed during the early 1950s with the intent of producing a capable successor to the earlier piston engine-powered airliners that had become commonplace on the market, such as the Douglas DC-3. A key innovation of the F27 was the adoption of the Rolls-Royce Dart turboprop engine, which produced substantially less vibration and noise which provided improved conditions for passengers; another major comfort feature was cabin pressurisation. Innovative manufacturing techniques were also employed in the aircraft's construction. On 24 November 1955, the F27 made its maiden flight; on 19 November 1958, the type was introduced to revenue service. Shortly after its introduction, the F27 was recognised as be ...

Fokker F28
The Fokker F28 Fellowship is a twin-engined, short-range jet airliner designed and built by Dutch aircraft manufacturer Fokker. Following the Fokker F27 Friendship, an early and commercially successful turboprop-powered regional airliner, Fokker decided to embark on developing a new turbojet-powered commuter aircraft that would build upon its experiences with the F27. During the design phase, a high level of attention was paid to market research and operator concerns; amongst other changes made, the prospective jetliner was increased in size, changing its maximum seating capacity from 50 to 65 passengers. During April 1962, Fokker announced the formal launch of the F28 Fellowship. On 9 May 1967, the prototype F28-1000 conducted its maiden flight. Type certification was achieved on 24 February 1969, and the first revenue-earning flight by Braathens was performed on 28 March 1969. Following its entry to service, Fokker developed multiple variants of the F28; one model, the F28-200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
