Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entities f ...

P-63 Kingcobra
The Bell P-63 Kingcobra is an American fighter aircraft that was developed by Bell Aircraft during World War II. Based on the preceding Bell P-39 Airacobra, the P-63's design incorporated suggestions from P-39 pilots and was superior to its predecessor in virtually all respects. The P-63 was not accepted for combat use by the United States Army Air Forces. However, it was used during World War II by the Soviet Air Force,Angelucci and Matricardi 1978, p. 100. which had also been the most prolific user of the P-39. Design and development XP-39E While the P-39 had been introduced as an interceptor, later in its development it was decided to reduce the cost and complexity of the engine by removing the turbocharger. High-altitude performance suffered dramatically as a result, and Bell proposed an experimental series to test out a variety of solutions. The resulting XP-39E featured two primary changes from the earlier P-39D from which it was developed. One was a redesigned wing. Th ...

Westland Aircraft
Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961. History Foundation In 1915 the Westland Aircraft Works was founded as a division of Petters in response to government orders for the construction under licence of initially 12 Short Type 184 seaplanes, followed by 20 Short Admiralty Type 166. Orders for other aircraft followed during First World War, including the Sopwith 1½ Strutter, the de Havilland designed Airco DH.4, Airco DH.9 and Airco DH.9A and the Vickers Vimy. The name ...

Bell 206
The Bell 206 is a family of two-bladed, single- and twin-engined helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec, plant. Originally developed as the Bell YOH-4 for the United States Army's Light Observation Helicopter program, it was not selected by the Army. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engined option as the TwinRanger, while Tridair Helicopters offers a similar conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation "B06" is used on flight plans for the JetRanger and LongRanger, and the designation "B06T" is used for the twin-engined TwinRangers. Development Origins and JetRanger On October 14, 1960, the United States Navy solicited responses from 25 aircraft manufacturers to a req ...

Agusta
Agusta was an Italian helicopter manufacturer. It was based in Samarate, Northern Italy. The company was founded by Count Giovanni Agusta in 1923, who flew his first airplane in 1907. The MV Agusta motorcycle manufacturer began as an offshoot of the Agusta aviation company at the end of the Second World War, as a means to save the jobs of employees of the Agusta firm. In July 2000, Agusta merged with Westland Helicopters to form AgustaWestland S.p.A., a Multinational corporation, multinational helicopter design and manufacturing company, and a wholly owned subsidiary of Finmeccanica. History From 1952, the company became involved in helicopter manufacturing, first building Bell Aircraft Corporation, Bell helicopters under licence, but later Sikorsky Aircraft, Sikorsky, Boeing and McDonnell Douglas products as well. The company also had ambitions to design and build its own helicopters. The Agusta A.101 and the Agusta A.106 can be considered the best of its earlier attempts. O ...

AgustaWestland
AgustaWestland was an Anglo-Italian helicopter design and manufacturing company, which was a wholly owned subsidiary of Finmeccanica (now known as Leonardo). It was formed in July 2000 as an Anglo-Italian multinational company, when Finmeccanica and GKN merged their respective helicopter subsidiaries (Agusta and Westland Helicopters) to form AgustaWestland, with each holding a 50% share. Finmeccanica acquired GKN's stake in AgustaWestland in 2004. In 2016, AgustaWestland was merged into Leonardo S.p.A. (formerly Finmeccanica), where it became the company's helicopters division under the Leonardo Helicopters brand. "AgustaWestland" still exists as a subsidiary of Leonardo but the AgustaWestland public brand is no longer promoted. History The collaboration between Agusta and Westland dates back to 1981, when the two companies established the European Helicopter Industries joint venture with the aim of developing a new medium-size utility helicopter, the EH101. In March 1999, Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, cap ...

Civil Aviation Authority
A civil aviation authority (CAA) is a national or supranational statutory authority that oversees the regulation of civil aviation, including the maintenance of an aircraft register. Role Due to the inherent dangers in the use of flight vehicles, national aviation authorities typically regulate the following critical aspects of aircraft airworthiness and their operation: * design of aircraft, engines, airborne equipment and ground-based equipment affecting flight safety * conditions of manufacture and testing of aircraft and equipment * maintenance of aircraft and equipment * operation of aircraft and equipment * licensing of pilots, air traffic controllers, flight dispatchers and maintenance engineers * licensing of airports and navigational aids * standards for air traffic control. Depending on the legal system of the jurisdiction, a CAA will derive its powers from an act of parliament (such as the Civil or Federal Aviation Act), and is then empowered to make regulations withi ...

Bell 30
The Bell 30 was the prototype for the first commercial helicopter, and the first helicopter built by the Bell Aircraft Company. Designed by Arthur M. Young, the type served as a demonstration testbed for the successful Bell 47. Development Young had experimented alone with helicopter designs using scale models, and in 1941 he approached the Bell Aircraft Corporation in Buffalo, New York. The company agreed to build a number of full-scale prototypes, and Young moved to Buffalo. With the main Bell factories immersed in war production, and to ensure a research and development program that was sufficiently private and free of distractions, Young and his team moved to the Buffalo suburb of Gardenville (West Seneca). The ''Ship 1'' prototype's first serious mishap occurred near the very end of 1942 in captive testing, when a Bell corporate pilot asked to try the Ship 1, while not using a seat belt and hanging onto the controls instead to stay in the open cockpit - this captive flight ...

Government Contracts
Government procurement or public procurement is the procurement of goods, services and works on behalf of a public authority, such as a government agency. Amounting to 12 percent of global GDP in 2018, government procurement accounts for a substantial part of the global economy. To prevent fraud, waste, corruption, or local protectionism, the laws of most countries regulate government procurement to some extent. Laws usually require the procuring authority to issue public tenders if the value of the procurement exceeds a certain threshold. Government procurement is also the subject of the Agreement on Government Procurement (GPA), a plurilateral international treaty under the auspices of the WTO. Overview Need for government procurement Government procurement is necessary because governments cannot produce all the inputs for the goods they provide themselves. Governments usually provide public goods, e.g. national defense or public infrastructure. Public goods are non-riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur M
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ...
