The Bell 429 GlobalRanger is a light, twin-engine helicopter developed by Bell Helicopter and Korea Aerospace Industries, based on the Bell 427. First flight of the Bell 429 prototype took place on February 27, 2007,〔("Bell Flies 429, Stretches Program" ). ''Rotor & Wing'', April 2007.〕 and received type certification on July 1, 2009.〔("Bell 429 Achieves Certification" ). Bell Helicopter, July 1, 2009.〕 The Bell 429 is capable of single-pilot IFR and Runway Category A operations.〔(Transport Canada Type Certificate Search )〕 ==Development== The impetus for developing the Bell 429 came primarily from the emergency medical services (EMS) industry, which has been looking for an updated helicopter. The Bell 427 was originally intended to address this market, but the 427's small cabin size would not adequately accommodate a patient litter,〔"Light Twin, Big Cabin", Aviation Week & Space Technology 170, 26 (June 29, 2009), p. 42.〕 and the systems did not support instrument flight rules (IFR) certification. Bell's original concept for the 429 was a stretched model 427〔Croft, John. ("Bell Canada: composites not a grey area" ). ''Flight International'', June 12, 2009.〕 (unveiled as the Bell 427s3i at the 2004 HAI helicopter show), but this still did not provide what Bell and its customer advisers were looking for.〔AW & ST: "... but the cabin was not big enough to attract operators, particularly the emergency medical service industry."〕 Bell abandoned the 427 airframe and went to its MAPL (Modular Affordable Product Line) concept airframe〔 that was still in conceptual development at the time. The 429 employs the all-new modular airframe concept and the advanced rotor blade design from the MAPL program, but maintains a derivative engine and rotor drive system from the 427. The basic model includes a glass cockpit and is certified for single pilot IFR. Bell partnered with Korea Aerospace Industries and Mitsui Bussan Aerospace of Japan in the helicopter's development.〔() 〕 Bell had flown most of the critical MAPL technology components using a 427 test bed aircraft by February 2006. The first completed 429 flew February 27, 2007.〔 Certification was originally planned for late 2007, but program schedule delays, primarily caused by parts and material shortages common to all aviation manufacturers in that time period, caused the manufacturer to stretch the development timetable.〔 In October 2007 the external configuration was set. In February 2008, Bell had three 429s in flight testing that had completed 600 hours.〔("Bell Provides 429 Program Update" ). Bell Helicopter, February 22, 2008.〕 The helicopter received type certification from Transport Canada Civil Aviation (TCCA) on July 1, 2009,〔 and from Federal Aviation Administration (FAA) by July 7, 2009.〔("FAA, TC Certify Bell 429" ). Rotor & Wing, July 7, 2009.〕 EASA certification was announced at Helitech on September 24, 2009.〔("Helitech 2009: Bell 429 achieves EASA Certification" ). Rotorhub, September 24, 2009.〕 FAA and EASA disagreed with TCCA's weight exemption allowing the 429 to operate for the Canadian Coast Guard.〔Stephens, Ernie. "(Docs Show FAA Was Angry Over Bell's Weight Exemption )" ''Rotor & Wing'', June 3, 2014. Accessed: June 8, 2014. (Archived ) on June 8, 2014.〕 As of June 2009, the Bell 429 had received over 301 orders.〔Croft, John. ("Bell: certification imminent for Bell 429 rotor rocket" ). ''Flight Daily News'', June 15, 2009.〕 The launch customer for the Bell 429 is Air Methods Corporation, the largest medevac provider in the United States. On July 7, 2009, the first customer aircraft (s/n 57006) was delivered to Air Methods (owner) and Mercy One (operator) at Bell's facility in Mirabel, Quebec.〔(New model certified ). ''Montreal Gazette'', July 8, 2009.〕〔(Bell Presents 429 To Its First Customer ). ''Textron website'', July 16, 2009.〕 The 429 conducted its high altitude certification testing at Leadville, Colorado and its high temperature certification at Lake Havasu City, Arizona. Further testing is also underway to establish maximum speeds (Vne) and climb rates (Vy) for operation with various door configurations (fixed, sliding, pilot, passenger, doors off). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bell 429 GlobalRanger」の詳細全文を読む スポンサード リンク
