Liphuputso tsa pele ho tsoa phuputsong ea pele ea lefats'e ea phello ea 100% ea mafura a tsitsitseng a sefofane (SAF) lienjineng ka bobeli tsa jete ea khoebo li fane ka liphello tse tšepisang tsa pele.

Thuto ea ECLIF3, e kenyeletsang Airbus, Rolls-Royce, setsi sa lipatlisiso sa Jeremane DLR le SAF mohlahisi Neste, e tšoaea lekhetlo la pele 100% SAF e lekantsoe ka nako e le 'ngoe ka lienjineri tse peli tsa sefofane sa baeti ba khoebo - Airbus A350 lifofane tse tsamaisoang ke lienjineri tsa Rolls-Royce Trent XWB.

Liteko tsa mesi e tsoang ka sefofaneng le tlhahlobo ea mobu e amanang le eona lenaneong la ECLIF3 li qalile pejana selemong sena mme li sa tsoa qala hape. Sehlopha sa lihlopha tse fapaneng, se kenyeletsang bafuputsi ba National Research Council of Canada le The University of Manchester, se rera ho phatlalatsa liphetho tsa sona likoranteng tsa thuto ho elella bofelong ba selemo se tlang le 2023.

Liphuputso tsa phuputso li tla tšehetsa boiteko bo ntseng bo tsoela pele ho Airbus le Rolls-Royce ho netefatsa hore lekala la lifofane le itokiselitse tšebeliso e kholo ea SAF e le karolo ea boikitlaetso bo pharaletseng ba ho felisa carbon dioxide indastering. Lifofane ha joale li lumelloa ho sebetsa feela ka motsoako oa 50% oa SAF le mafura a tloaelehileng a jet, empa lik'hamphani ka bobeli li tšehetsa morero oa ho netefatsa tšebeliso ea 100% ea SAF.

Ka Mmesa, the A350 e fofisitse lifofane tse tharo holim'a Leoatle la Mediterranean tse lateloang ke sefofane sa DLR Falcon chaser ho bapisa mesi e tsoang ka sefofaneng ea parafene le Neste's hydro-processed esters and fatty acids (HEFA) mafura a tšoarellang. Sehlopha se boetse se entse liteko tsa ho latela melao ka ho sebelisa 100% SAF mme ha ho mathata a ts'ebetso a bileng teng.

Liteko tsa ho ntša mosi ka sefofaneng tse sebelisang 100% SAF le motsoako oa mafura oa HEFA/Jet A-1 li qalile khoeling ena, ha tlhahlobo ea mesi e thehiloeng fatše ho fumana melemo ea SAF mabapi le boleng ba moea oa lehae le eona e entsoe. Sehlopha sa bafuputsi se fumane SAF e lokolla likaroloana tse fokolang ho feta parafine e tloaelehileng maemong ohle a lekiloeng a ts'ebetso ea enjine, e supang monyetla oa ho fokotsa tšusumetso ea boemo ba leholimo le ntlafatso ea boleng ba moea ho potoloha boemafofane.

Ntle le moo, SAF e na le matla a tlase empa a na le matla a phahameng ka kilogram ea mafura ha a bapisoa le parafine e tloaelehileng, e tlisang melemo e meng ea tšebeliso ea mafura a sefofane ka lebaka la ho chesa mafura a tlase le boima bo fokolang ba mafura ho palama ho fihlela sepheo se tšoanang. Tlhahlobo e felletseng ea sehlopha e ntse e tsoela pele.

"Lienjiniere le lisebelisoa tsa mafura li ka lekoa fatše empa mokhoa o le mong feela oa ho bokella lintlha tse feletseng tsa mesi e hlokahalang bakeng sa lenaneo lena hore le atlehe ke ho fofa sefofane maemong a sebele," ho boletse Steven Le Moing, Mookameli oa Lenaneo le Lecha la Matla. Airbus. “Teko ea ka sefofaneng ea A350 e fana ka monyetla oa ho hlahisa mesi e tsoang ka kotloloho le e sa tobang, ho kenyelletsa le likaroloana tse tsoang ka morao ho sefofane se bophahamong bo phahameng.

Simon Burr, Motsamaisi oa Rolls-Royce oa Nts'etsopele ea Lihlahisoa le Theknoloji, Civil Aerospace, o itse: "Phuputso ena e eketsa liteko tseo re seng re li entse lienjineng tsa rona, fatše le moeeng, tse sa fumaneng tšitiso ea boenjiniere. dienjini tsa rona tse mathang ka 100% SAF. Haeba re hlile re batla ho felisa maeto a sefofane a nako e telele, joale 100% SAF ke ntho ea bohlokoa 'me re ikemiselitse ho tšehetsa setifikeiti sa eona sa ts'ebeletso. ”

Sefofane sa DLR Falcon chaser se na le lisebelisoa tse ngata tsa ho lekanya likhase tse tsoang maemong a sekepe ho ea fihla bohole ba limithara tse 100 feela ho tloha A350 le ho li fa lisebelisoa tsa mahlale bakeng sa tlhahlobo.

"SAF e bonts'itsoe hore e na le khabone e tlase haholo nakong ea bophelo ba eona ha e bapisoa le mafura a jet a tloaelehileng 'me joale re bona ho le molemo ho fokotsa li-non-CO.₂ litlamorao le tsona," ho boletse Markus Fischer, Setho sa Boto ea Karolo ea DLR bakeng sa Aeronautics. "Liteko tse kang tsena li ntse li tsoela pele ho ntlafatsa kutloisiso ea rona ea 100% SAF, tšebeliso ea eona sefofaneng 'me re bona matšoao a nepahetseng bakeng sa bokhoni ba eona ba ho fokotsa boemo ba leholimo. Re labalabela ho ithuta lintlha tse tsoang letotong la bobeli la lifofane tsa ECLIF3, tse qalileng hape ka sefofane sa pele sa ho lelekisa Mediterranean pejana khoeling ena. ”

Ka 2015, DLR e ile ea etsa lets'olo la ECLIF1, e batlisisa ka mafura a mang ka sefofane sa eona sa lipatlisiso sa Falcon le A320 ATRA. Lipatlisiso tsena li tsoetse pele ka 2018 ka lets'olo la ECLIF2 le boneng A320 ATRA e fofa ka motsoako oa mafura a jete a tloaelehileng le ho fihla ho 50% HEFA. Patlisiso ena e bonts'itse ts'ebetso e ntle ea tlhahiso ea mafura ho fihla ho 50% SAF mme e butse tsela bakeng sa lifofane tsa liteko tsa 100% tsa SAF bakeng sa ECLIF3.

“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.
Liphuputso tsa phuputso li tla tšehetsa boiteko bo ntseng bo tsoela pele ho Airbus le Rolls-Royce ho netefatsa hore lekala la lifofane le itokiselitse tšebeliso e kholo ea SAF e le karolo ea boikitlaetso bo pharaletseng ba ho felisa carbon dioxide indastering.
“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.
