ʻO nā ʻike mua mai kahi noiʻi mua o ka honua i ka hopena o 100% sustainable aviation fuel (SAF) ma nā ʻenekini ʻelua o kahi mokulele kalepa i hāʻawi i nā hopena mua.

ʻO ka haʻawina ECLIF3, e pili ana Airbus, Rolls-Royce, ke kikowaena noiʻi Kelemania DLR a me ka mea hana SAF Neste, hōʻailona i ka manawa mua 100% SAF i ana ʻia i ka manawa like ma nā ʻenekini ʻelua o kahi mokulele mokulele kalepa - he Airbus A350 mokulele i hoʻohana ʻia e nā ʻenekini Rolls-Royce Trent XWB.

Ua hoʻomaka ka hoʻāʻo ʻana o ka hoʻokuʻu ʻana i ka mokulele a me ka hoʻāʻo ʻana i ka honua ma ka papahana ECLIF3 ma mua o kēia makahiki a ua hoʻomaka hou. Hoʻolālā ka hui interdisciplinary, ʻo ia hoʻi nā mea noiʻi mai ka National Research Council of Canada a me The University of Manchester, e hoʻolaha i kāna mau hopena i loko o nā puke puke haʻawina i ka hopena o ka makahiki aʻe a me 2023.

E kākoʻo nā ʻike mai ke aʻo ʻana i nā hana i kēia manawa ma Airbus a me Rolls-Royce e hōʻoia i ka mākaukau o ka ʻoihana mokulele no ka hoʻohana nui ʻana o SAF ma ke ʻano he ʻāpana o ka hoʻolālā ākea e decarbonize i ka ʻoihana. Ke ʻae ʻia nei nā mokulele e hana ma kahi hui 50% o ka SAF a me ka wahie mokulele maʻamau, akā kākoʻo nā hui ʻelua i ka hoʻokele e hōʻoia i ka hoʻohana ʻana o 100% SAF.

I ʻApelila, ka A350 lele ʻekolu mau mokulele ma luna o ke Kai Kaiwaenahonua i alualu ʻia e kahi mokulele ʻo DLR Falcon chaser e hoʻohālikelike i ka hoʻokuʻu ʻana i ka lele ʻana o nā kerosene a me nā esters hydro-processed a me nā momona momona o Neste (HEFA) wahie hoʻomau. Ua hana pū ka hui i nā hoʻokolohua hoʻokō me ka hoʻohana ʻana i 100% SAF a ʻaʻohe pilikia o ka hana.

Ua hoʻomaka hou ʻia nā hoʻāʻo hoʻokuʻu ʻana i loko o ka mokulele e hoʻohana ana i ka 100% SAF a me ka hui ʻana o ka wahie HEFA/Jet A-1 i kēia mahina, ʻoiai ua hana pū ʻia nā hoʻāʻo ʻana o ka hoʻokuʻu ʻana i ka honua no ka helu ʻana i nā pono o SAF ma ka maikaʻi o ka ea kūloko. Ua ʻike ka hui noiʻi i ka hoʻokuʻu ʻana o SAF i nā ʻāpana liʻiliʻi ma mua o ka ʻaila maʻamau i nā kūlana hana ʻenekini i hoʻāʻo ʻia, e kuhikuhi ana i ka hiki ke hoʻemi i ka hopena o ke aniau a me ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ea a puni nā mokulele.

Eia kekahi, he haʻahaʻa haʻahaʻa ka SAF akā ʻoi aku ka nui o ka ikehu ma ka kilo o ka wahie i hoʻohālikelike ʻia me ka kerosene maʻamau, e lawe mai ana i kekahi mau pono kūpono o ka mokulele ma muli o ka haʻahaʻa wahie a me ka liʻiliʻi o ka wahie i ka papa e hoʻokō ai i ka misionari like. Ke hoʻomau nei ka ʻike kikoʻī a ka hui.

"Hiki ke hoʻāʻo ʻia nā ʻenekini a me nā ʻōnaehana wahie ma ka ʻāina akā ʻo ke ala wale nō e hōʻiliʻili ai i ka ʻikepili piha o nā emissions e pono ai no kēia papahana e kūleʻa ai ka lele ʻana i kahi mokulele i nā kūlana maoli," wahi a Steven Le Moing, New Energy Program Manager ma Airbus. “Ma ka lele ʻana o ka hoʻāʻo ʻana o ka A350 hāʻawi i ka pono o ka hōʻike ʻana i ka hoʻokuʻu ʻia ʻana o ka mīkini pololei a me ka ʻole, me nā ʻāpana mai hope o kahi mokulele ma ke kiʻekiʻe kiʻekiʻe.

Ua ʻōlelo ʻo Simon Burr, Rolls-Royce Luna Hoʻokele o ka Hoʻomohala ʻana a me ka ʻenehana, Civil Aerospace: "Hoʻohui kēia noiʻi i nā hoʻokolohua a mākou i hana mua ai i kā mākou mau mīkini, ma ka ʻāina a ma ka lewa, ʻaʻole i loaʻa kahi pilikia ʻenekinia. e holo ana kā mākou mau mīkini ma 100% SAF. Inā makemake mākou e hoʻokaʻawale i ka huakaʻi hele lōʻihi, a laila ʻo 100% SAF kahi mea koʻikoʻi a paʻa mākou i ke kākoʻo ʻana i kāna palapala hōʻoia no ka lawelawe.

Hoʻolako ʻia ka mokulele ʻo DLR Falcon chaser me nā ʻimi noiʻi he nui e ana i nā hoʻokuʻu ʻana ma ka pae holo moana a hiki i kahi mamao o 100 mika wale nō mai ka A350 a hānai iā lākou i nā mea hana ʻepekema no ka nānā ʻana.

"Ua hōʻike ʻia ka SAF he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma luna o kona pōʻai ola e hoʻohālikelike ʻia me ka wahie jet maʻamau a ke ʻike nei mākou he mea maikaʻi ia i ka hōʻemi ʻana i ka non-CO.₂ nā hopena hoʻi, "wahi a Markus Fischer, ka Luna Hoʻokele Mokuna o DLR no Aeronautics. "Ke hoʻomau nei nā hoʻokolohua e like me kēia i ka hoʻomohala ʻana i ko mākou ʻike no 100% SAF, kona hoʻohana ʻana i ka lele a ke ʻike nei mākou i nā hōʻailona maikaʻi no kona hiki ke hoʻemi i ke aniau. Manaʻo mākou i ke aʻo ʻana i ka ʻikepili mai ka lua o nā mokulele ECLIF3, i hoʻomaka hou me kahi lele alualu mua ma luna o ke Kaiwaenahonua ma mua o kēia mahina.

I ka makahiki 2015, hana ʻo DLR i ka hoʻolaha ECLIF1, e noiʻi ana i nā wahie ʻē aʻe me kāna mokulele Falcon a me A320 ATRA. Ua hoʻomau kēia mau noiʻi ma 2018 me ka hoʻolaha ECLIF2 i ʻike i ka lele ʻana o ka A320 ATRA me ka hui ʻana o ka wahie jet maʻamau a hiki i ka 50% HEFA. Ua hōʻike kēia noiʻi i ka maikaʻi o ka hoʻokuʻu ʻana o nā huila wahie a hiki i ka 50% SAF a hoʻopaʻa i ke ala no nā mokulele hoʻāʻo 100% SAF no ECLIF3.

He aha e lawe ʻia mai kēia ʻatikala:

“Engines and fuel systems can be tested on the ground but the only way to gather the full set of emissions data necessary for this program to be successful is to fly an aircraft in real conditions,” said Steven Le Moing, New Energy Program Manager at Airbus.
E kākoʻo nā ʻike mai ka noiʻi ʻana i nā hana e hana nei i kēia manawa ma Airbus a me Rolls-Royce e hōʻoia i ka mākaukau o ka ʻoihana mokulele no ka hoʻohana nui ʻana o SAF ma ke ʻano he ʻāpana o ka hoʻolālā ākea e decarbonize i ka ʻoihana.
“This research adds to tests we've already carried out on our engines, both on the ground and in the air, which have found no engineering obstacle to our engines running on 100% SAF.
