초록

Anti-G 밸브는 Anti-G Suit에 연결되어 급격한 기동 시 조종사에게 적절한 여압기능을 제공한다. 또한 Anti-G 밸브는 연결된 레귤레이터를 조종하여 기동 간 조종사의 생리학적 산소요구량 증가에 따라 적절한 PBG(Pressure Breathing for G)가 제공되도록 조절한다. FA-50과 같이 고기동 임무가 요구되는 항공기에서 Anti-G 밸브는 조종사의 생존 및 항공기의 안전을 위해 매우 중요한 요소이다. 본 논문에서는 Anti-G 밸브 개발 중 발생된 문제점을 바탕으로 개발 요구도 및 설계개선 내용을 기술하였으며, 개선된 연구에 대해 구성품 성능시험 및 비행시험검증 결과를 함께 소개한다.

This paper deals with the improvement of pressurized quality for high maneuver aircraft. Anti-G Valve is a pressure regulating valve for inflating anti-G suits and providing a sense line signal for a g-compensated oxygen regulator. The new anti-g valve system is satisfied with military specification MIL-V-87255 and allowed the pilots to tolerate high-G exposures without any vibrations. The flight test was performed by two T/FA-50 pilots and other tests used the centrifuge made by anti-g developer. A comparison of the new anti-g valve with period one, it have better response and low chattering phenomenon.
