The KAI KUH-1 Surion is a twin-engine, transport utility helicopter developed primarily by Korea Aerospace Industries (KAI), Agency for Defense Development (ADD) and Korea Aerospace Research Institute (KARI) jointly with Eurocopter. The Korea Helicopter Project - Korea Utility Helicopter (KHP-KUH) r&d program is to cost about 1.3 trillion won ($1.2 billion), and was launched in 2006 under the Agency for Defense Development. Full-scale production began in 2012 with KAI being the principal builder.〔 Around 245 Surions are on order to replace the aging fleet of UH-1H utility helicopters and 500MD light utility helicopters,〔 which have been in service for decades. South Korea will also build civilian and law enforcement variants of the helicopter.〔 ==Development== In June 2006, KAI and Eurocopter won the KHP-KUH 1.3 trillion-won ($1.2 billion) research and development contract from the Defense Acquisition Program Administration (DAPA) to start the project. It remains Seoul's biggest arms deal ever with a non-US company. The development of the aircraft was funded 84% by the South Korean government and 16% by Korea Aerospace Industries(KAI) and Eurocopter. A production contract worth about 4.4 trillion won ($4.3 billion) is expected to be signed around 2011 before the start of mass production. Eurocopter has a stake of 30 percent in the 2006-2012 development phase and 20 percent in the following ten-year production phase, and KAI and South Korea government having the rest. As the prime sub-contractor, Eurocopter has provided technical assistance in part for developing the power transmission, main gearbox, boom and tail gearboxes, automatic flight control system and rotor mast.〔 Eurocopter experts were dispatched to KAI premises (Sacheon, South Korea) to provide support and teach KAI engineers the state of the art in helicopter design.〔 Power is provided by a pair of 1,600 shp Samsung Techwin T700-ST-701K turboshafts.〔(【引用サイトリンク】title=Turboshaft Power Supporting Global Markets and Missions )〕 Under the contract, T700/701K, co-developed by General Electric and Samsung Techwin, is the inaugural rear-drive T700 engine and features a -701D common core, high-efficiency counterrotating power turbine, and a new FADEC system.〔(【引用サイトリンク】title=GE's T700 Engines To Power Korean Helicopter Program (KHP) )〕 Elbit Systems of Israel produces the Helmet mounted display (HMD), an advanced system which allow the pilot/copilot full day and night missions. A large IR suppressor exhausts of the Surion are adapted from those of the Eurocopter EC 725. The first prototype was unveiled by President Lee Myung-bak at an unveiling ceremony in Sacheon. In 2009, there was a delay in the program due to budget trimming of some ministries. On 22 May 2013 it was announced that ten Surions had been deployed to the Army Aviation School in Nonsan, South Chungcheong Province following a handover ceremony attended by President Park Geun-hye. In 2016, KAI plans to increase production of the helicopter from one per month to three per month.〔 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「KAI KUH-1 Surion」の詳細全文を読む スポンサード リンク
