Abstract

In Europe and USA, new programs called GRC(Green Rotorcraft) and SRW (Subsonic Rotary Wing program) respectively, have been currently underway for developing the next generation rotorcraft. The final goal is to develope fuel-efficient/environmental-friendly tilt-rotor civilian rotorcraft, which can partly replace short-range regional aircrafts. Also for safe operation, the new rotorcraft technology is cooperated with the new air transport management(ATM) system, called SESAR(Single European Sky ATM Research) and NextGen(Next Generation Air Transport System) in Europe and USA. In addition to achieve the final goal, the tilt-rotor aircraft, they are trying to improve the performance of conventional helicopters by adopting more efficient propulsion system, active rotor system, and reducing internal and external noise. Especially in GRC program of Europe, the environmental factors such as noise, fuel efficiency, reduction of emission gas(CO2, NOx), are focused for the new technologies.

현재 유럽과 미국에서는 각각 GRC(Green Rotorcraft) 와 SRW (Subsonic Rotary Wing program) 프로그램을 통하여 차세대 회전익기 개발이 진행 중에 있다. 이들 프로그램의 최종 목적은 현재 사용 중에 있는 단거리 여객기를 일부 대체 할 수 있는 틸트로터 타입의 중/소형 민간 회전익기 개발에 목적을 두고 있다. 또한 이들 틸트 로터의 민간 운영에 운영할 수 있는 안전한 운행을 위하여, 각각 개발 중인 air transport management(ATM) 시스템인 SESAR(Single European Sky ATM Research) 와 NextGen(Next Generation Air Transport System)과 융합하는 기술도 병행되고 있다. 이들 프로그램들은, 최종 목표인 틸트 로터기의 개발이 진행되는 중간 과정으로, 현재 사용되고 있는 헬리콥터의 성능의 향상도 병행하고 있다. 이러한 성능 개발은 좀 더 효율적인 추진기관, 능동 로터 시스템, 내/외부의 소음 감소 등에 중점을 두고 있다. 특히 유럽의 GRC 프로그램에서는 소음, 연료소비율, 배기가스 (CO2, NOx)의 절감 등에 매우 구체적인 목표를 설정하여 기술 개발을 진행 중에 있다.
