EC-635
The Eurocopter EC635 (now Airbus Helicopters H135M) is a multi-purpose light helicopter developed by Eurocopter (now Airbus Helicopters) as a military version of the Eurocopter EC135. It is a twin-engined aircraft and can carry up to 8 people, including the pilot, and a range of military equipment or armaments. The helicopter is marketed for troop transport, medical evacuation, cargo transport, reconnaissance and surveillance and armed combat support missions. Development The Eurocopter EC635 was developed to meet a Portuguese Army requirement for a light fire support and MEDEVAC, medical evacuation helicopter, as part of its programme for the raise of a specialist army aviation unit, the UALE. The EC635 was first revealed at the Aviation Africa exhibition in May 1998 and the Ministry of National Defence (Portugal), Portuguese Ministry of Defence subsequently signed an agreement for nine EC635 T2 helicopters equipped with Turbomeca Turbomeca Arrius, Arrius 2B2 engines, at a cost ...

UALE
The Army Light Aviation Unit ( pt, Unidade de Aviação Ligeira do Exército, UALE) was the planned aviation unit of the Portuguese Army. Created in 2000 as the Army Light Aviation Group (GALE), it was the Army's unit dedicated to missions of light aviation, being integrated in the Army Forces System, under the operational command of the Ground Forces Operational Command ( pt, Comando Operacional das Forças Terrestres). It was planned to be equipped with light fire support and medium maneuver helicopters. The process of helicopter procurement, however, suffered successive setbacks until being finally canceled in 2012, causing the unit disbandment in 2015. History Background The Portuguese Army maintained its own aviation arm from 1914 to 1952. This arm received a high degree of autonomy in 1937, including its own separate chain of command, although continuing to be administratively connected to the Army. In the early 1950s, the decision was taken to completely separate it fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swiss Air Force
The Swiss Air Force (german: Schweizer Luftwaffe; french: Forces aériennes suisses; it, Forze aeree svizzere; rm, Aviatica militara svizra) is the air component of the Swiss Armed Forces, established on 31 July 1914 as a part of the army and in October 1936 as an independent service. In peacetime, Dübendorf is the operational air force headquarters. The Swiss Air Force operates from several fixed bases (see current status) but its personnel are also trained to carry out air operations from temporary highway airstrips. In case of crisis or war, several stretches of road are specially prepared for this option. History Early years The first military aviation in Switzerland took the form of balloon transport, pioneered by Swiss balloonist Eduard Spelterini, but by 1914 there was still little official support for an air corps. The outbreak of World War I changed opinions drastically and cavalry officer Theodor Real was charged with forming a flying corps. He commandeered three ...

Royal Jordanian Air Force
The Royal Jordanian Air Force (RJAF; ar, سلاح الجو الملكي الأردني, Silāḥ ul-Jawu al-Malakī 'al-Urdunī) is the aerial warfare branch of the Jordanian Armed Forces. History Early days Jordan gained independence in 1946, but its first air bases had been set up in 1931 by the Royal Air Force. By 1948, Jordan began to develop a small air arm which came to be known as the Arab Legion Air Force (ALAF). The Royal Air Force assisted in training this small air arm and provided equipment. The ALAF's primary fighter was the de Havilland Vampire and a Vickers VC.1 Viking was operated as a VIP aircraft for use by the King of Jordan. By 1955 King Hussein realized the need for Jordan to have a more modern air force, and on 25 September 1955 the RJAF was established. By 1958 the Royal Air Force had left Jordan and the RJAF had taken control of the airfields in the country. 1960s In 1967, in the Six-Day War, the Israeli Air Force relentlessly attacked Jordan's Air ...

FADEC
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an "electronic engine controller" (EEC) or "engine control unit" (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines. History The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition. Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine. By moving these levers the pilot or the flight engineer could control fuel flow, power output, and many other engine parameters. The mechanical/hydraulic engine control unit for Germany's BMW 801 piston aviation radial engine of World War II was just one notable example of this in its later stages of development. This mechanical engine control was progressively replaced first by analog electronic engine control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibre-reinforced Plastic
Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English ''fiber'') is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use. FRPs are commonly used in the aerospace, automotive, marine, and construction industries. They are commonly found in ballistic armour and cylinders for self-contained breathing apparatuses. Process definition A polymer is generally manufactured by step-growth polymerization or addition polymerization. When combined with various agents to enhance or in any way alter the material properties of polymers, the result is referred to as a plastic. Composite plastics refers to those types of plastic ...

Fenestron
A Fenestron (sometimes alternatively referred to as a fantail or a "fan-in-fin" arrangementLeishman 2006, p. 321.) is an enclosed helicopter tail rotor that operates like a ducted fan. The term ''Fenestron'' is a trademark of multinational helicopter manufacturing consortium Airbus Helicopters (formerly known as Eurocopter). The word itself comes from the Occitan term for a ''small window'', and is ultimately derived from the Latin word ''fenestra'' for ''window''.Prouty, Ray. ''Helicopter Aerodynamics'', Helobooks, 1985, 2004. p. 266. The Fenestron differs from a conventional open tail rotor by being integrally housed within the tail boom, and like the conventional tail rotor it replaces, functions to counteract the torque generated by the main rotor. While conventional tail rotors typically have two or four blades, Fenestrons have between seven and eighteen blades; these may have variable angular spacing so that the noise is distributed over different frequencies.
