Ko te Mīhini Whakapūngao Ārai (AJM) he tukanga mīhini e whakamahi ana i ngā matūriki whakapūngao iti e panaia ana i te tere tiketike mai i ngā kōhao o te pūwero hei mahi ki te mata o te mea mahi, hei huri me te tango i te rauemi mā te tukinga tere tiketike me te kutikuti i ngā matūriki.
Haunga te rongoā mata mō te whakaoti mata, tae atu ki te paninga, te whakarewa me te whakakikorua i mua i te maimoatanga, i muri rānei i te maimoatanga, i roto i te hangahanga, he tino pai ngā pūwāhi miihini iti mō te tapahi pereti, te whakakanapa mata wāhi, te mira, te huri, te keri me te raranga mata, e tohu ana ka taea te whakamahi i te jet whakakanapa hei wira huri, taputapu huri, taputapu tapahi mira, wiri me ētahi atu taputapu tuku iho.
Ā, mai i te āhua, i te pūtake rānei o te jet, ka wehea te hangarau jet whakakoi ki ngā jet wai (whakakoi), ngā jet paru, ngā jet hau whakakoi me ērā atu. I tēnei rā, ka kōrero tuatahi tātou mō te whanaketanga o te hangarau jet wai whakakoi.
I whakawhanakehia te wai whakakoi i runga i te wai whakakoi parakore. I ahu mai te Wai Whakakoi (WJ) i te tekau tau atu i 1930, ko tētahi ariā he keri waro, ko tētahi he tapahi i tētahi rauemi motuhake. I ngā rā o mua, ko te pēhanga ka taea e te wai whakakoi te tae atu kei roto i te 10 MPa, ā, ka taea anake te whakamahi mō te horoi i ngā hononga waro, te tapahi i ngā rauemi ngohengohe pērā i te pepa me te kakahu, me ētahi atu. Heoi, i te taha o te whanaketanga o te pūtaiao me te hangarau, i puta mai he maha ngā momo auaha hou whakahihiri i roto i te mara o te wai whakakoi o te ao i te mutunga o te tekau tau atu i 1970, ko tētahi o ēnei ko te Wai Whakakoi (AWJ) i whakatakotoria e Tākuta Mohamed Hashish i te tau 1979.
