Umgaqo wokukhutshwa kombhobho wefeni othe tyaba uhlukile kuleyo yombhobho wefeni othe tyaba. Ubume bokukhutshwa kombhobho we-axial flat fan wenziwa ngenxa yokuba ulwelo lukhutshiwe emva kokuxinzezelwa ukwenza ifom ye-fan fan ejection. Ukuphambuka umlomo wombhobho wefeni ngokuthe gabalala kuthetha ukuba ulwelo ludlula kumngxunya wesetyhula kwaye emva koko lubethe ukuphambuka komhlaba. Uyilo lommandla wokuphambuka lubaluleke ngokukodwa, kwaye ludlala indima ebonakalayo kwisiphumo sejeti. Ngokubanzi, kukho ukubamba umlomo. IArc yenziwa ngokongeza umgca othe ngqo.

Oku kungasentla kukuphambuka okubanzi kwe-engile yefeni, kwaye kukwakho nomlomo omncinci wecala elisezantsi. Umgaqo-siseko osebenzayo ngokufanayo uyafana nowe-engile ebanzi.
