C-17A가 역추진해서 후진할 때 땅의 맨홀 뚜껑이 들려 올라온 일이 있었다고 합니다. 2001-2002년의 아프가니스탄 작전 때 비포장 활주로에서 손상을 입은 일도 있고요.
During contingency missions to Afghanistan during Operation ENDURING FREEDOM at least one C-17 sustained damage to landing gear wheel and brake assemblies (Papetti, 2002) caused by the buildup of dirt and mud. This buildup prevented the brake and wheel assemblies from rotating freely and resulted in cracked brake discs. Ten of the twelve wheel and tire assemblies as well as all twelve brake assemblies were replaced to correct the damage.
Although the C-17’s engines are mounted over 8 feet from the ground, there is still danger of FOD ingestion due to the large amount of suction created by the turbines when running at high speeds. This suction often creates a high-speed rotating funnel of air called a vortex during C-17 ground operations. These vortices are especially prevalent during aircraft backing operations under high thrust requirements. On at least one occasion this vortex lifted a manhole cover from the ground while the aircraft was performing backing operations.
첫댓글 프롭 선택에 대한 필사적인 변호가 느껴지네요? 그나저나 C-2는 요새 분석하는데 항속/페이로드/연료량이 뭔가 기묘하게 아다리가 안맞는 느낌이네요

아래 PDF 207쪽에 있는 C-2 민간형 YCX의 Payload-Range가 실제보다 크게 나왔을 수 있을라나요?

@백선호 위키에 나온 숫자를 구현? 중인데 다른 기체들 대비 깔끔하게 구성이 안되네요ㅜ
터보프롭도 엔진 흡입구가 없는 건 아닌데 아무래도 면적이 적다보니 FOD 유입 가능성이 터보팬보다 낮긴 하겠습니다. 프로펠러에서 자잘한 돌맹이들은 날려버릴 수도 있을 것 같고.
커다란 터보팬에 비하면 훨씬 낮지요.
프롭들은 발 짧은 전술수송 측면에서... 일단 미래 전장에서 수송기가 뜨고 내릴 수 있느냐는 질문부터... -.- ㅋㅋㅋㅋㅋ.
UAE의 수송기는 이란이 쳐들어오면 왕실 보물들 싣고 해외로 튀는데 쓰려는 것 아닐까요? ㅎㅎ
