Harbin Y-12
The Harbin Y-12 () is a high wing twin-engine turboprop utility aircraft built by Harbin Aircraft Industry Group (HAIG). Design and development The Y-12 started as a development of the Harbin Y-11 airframe called Y-11T in 1980. The design featured numerous improvements including a redesigned wing with a new low drag section, a larger fuselage and bonded rather than riveted construction. It also replaced the radial piston engines with turboprops. The prototype was followed by about 30 production Y-12 (I) aircraft before a revised version was produced. This was designated the Y-12 (II), which featured more powerful engines and removal of leading edge slats, first flying on 16 August 1984 and receiving Chinese certification in December of the following year.JWR Taylor 1988, p.38. The power plants are two Pratt & Whitney Canada PT6A-27 turboprops with Hartzell propellers. The Y-12 has a maximum takeoff weight of 5,700 kg (12,600 lb) with seating for 17 passengers and ...

Aerospace Force Of The Islamic Revolutionary Guard Corps
The Islamic Revolutionary Guard Corps Aerospace Force or Islamic Revolutionary Guard Corps Air and Space Force (IRGCASF; fa, نیروی هوافضای سپاه پاسداران انقلاب اسلامی, niru-ye havâfazây-e sepâh-e pâsdârân-e enghelâb-e eslâmi, officially acronymed NEHSA) is the strategic missile, air, and space force within the Islamic Revolutionary Guard Corps (IRGC) of Iran. It was renamed from the IRGC Air Force into the IRGC Aerospace Force in 2009. Aviation forces Most American public sources disagree and argue on which aircraft are operated by the AFAGIR. The Washington Institute for Near East Policy said in 2005 that " e backbone of the IRGCAF consists of ten Su-25 Frogfoot attack aircraft (including seven flown from Iraq to Iran during the 1991 Gulf War, kept airworthy with the help of Georgian technicians) and around forty EMB-312 Tucanos". The Washington Institute also said that the IRGCAF maintained thirty Y-12 and Dassault Falcon 20 li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation 'prototypical'. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms such as stereotypes and archetypes. The word ''wikt:prototype, prototype'' derives from the Greek language, Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Civil Aviation Administration Of China
The Civil Aviation Administration of China (CAAC; ) is the Chinese civil aviation authority under the Ministry of Transport. It oversees civil aviation and investigates aviation accidents and incidents. As the aviation authority responsible for China, it concludes civil aviation agreements with other aviation authorities, including those of the Special administrative regions of China which are categorized as "special domestic." It directly operated its own airline, China's aviation monopoly, until 1988. The agency is headquartered in Dongcheng District, Beijing. The CAAC does not share the responsibility of managing China's airspace with the Central Military Commission under the regulations in the Civil Aviation Law of the People's Republic of China.

Regional Airline
A regional airline is a general classification of airline which typically operates scheduled passenger air service, using regional aircraft, between communities lacking sufficient demand or infrastructure to attract mainline flights. In North America, most regional airlines are classified as "fee-for-departure" carriers, operating their revenue flights as codeshare services contracted by one or more major airline partners. A number of regional airlines, particularly in during the 1960s and 1970s, were also known as commuter airlines and classified as such in the Official Airline Guide (OAG). History Background Decades before the advent of jet airliners and high-speed, long-range air service, commercial aviation was structured similarly to rail transport networks. In this era, technological limitations on air navigation and propeller-driven aircraft performance imposed strict constraints on the potential length of each flight; some routes covered less than . As such, ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passengers
A passenger (also abbreviated as pax) is a person who travels in a vehicle, but does not bear any responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle, and is not a steward. The vehicles may be bicycles, buses, passenger trains, airliners, ships, ferryboats, and other methods of transportation. Crew members (if any), as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a passenger while on duty and the same with those working in the kitchen or restaurant on board a ship as well as cleaning staff, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being driven on company business. Railways In railway parlance, passenger, as well as being the end user of a service, is also a categorisation of the type of rolling stock used.Simmon ...

Propellers
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the water at t ...
