Qantas Boeing 747 wopuma pantchito amakhala Rolls-Royce flying testbed

Wokondedwa kwambiri Qantas ndege zonyamula anthu zapuma pantchito zamalonda sabata ino kuti ziyambe moyo ngati a Rolls-Royce testbed yowuluka. Ndegeyi idzagwiritsidwa ntchito kuyesa luso lamakono ndi lamtsogolo la injini ya jet yomwe idzasinthe maulendo a ndege, kuchepetsa mpweya woipa komanso kukhazikitsa zizindikiro zatsopano zogwirira ntchito.

The Boeing 747-400 - ndi kulembetsa kwa VH-OJU - wakhala akugwira ntchito ndi Qantas kwa zaka 20 monga membala wokondedwa kwambiri wa zombo zonyamula katundu ku Australia. Pazaka zonse za moyo wake, OJU yayenda makilomita oposa 70 miliyoni, yomwe ili yofanana ndi maulendo pafupifupi 100 obwerera ku mwezi. Yakhala ikugwira ntchito kumayiko ambiri ndikunyamula anthu okwera 2.5 miliyoni, ndipo ulendo uliwonse umayendetsedwa ndi injini zinayi za Rolls-Royce RB211.

Monga testbed yowuluka, ikhala ndi zida zaposachedwa kwambiri zoyeserera ndipo kwa nthawi yoyamba, idzayesa ma injini omwe amayendetsa ndege zamalonda ndi zamalonda. Machitidwe atsopano adzapeza deta yabwinoko mofulumira kuposa kale lonse, ndipo matekinoloje adzayesedwa pamtunda wapamwamba komanso mofulumira kwambiri. Ma testbed owuluka amagwiritsidwa ntchito poyesa mtunda ndikuyang'anira matekinoloje pamaulendo apaulendo.

Ogwira ntchito ku Rolls-Royce adzasankha dzina la ndegeyo, yomwe idatumikira moyo wake ndi Qantas yotchedwa Lord Howe Island. Idzayendetsedwa ndi gulu la akatswiri oyendetsa ndege oyesa, omwe amaphatikiza ukadaulo waukadaulo ndi zaka zambiri zakuwuluka zamalonda, zankhondo komanso ndege zoyesa.

Ndege yatsopanoyi imathandizira masomphenya a Rolls-Royce IntelligentEngine, pomwe injini zimalumikizidwa, kudziwa zenizeni komanso kumvetsetsa, kuyambira nthawi yawo pa testbed.

747 idamaliza ndege yake yomaliza yopita ku Qantas pa 13 Okutobala 2019 kuchokera ku Sydney kupita ku Los Angeles. Kenako idawulukira ku malo oyesera ndege a AeroTEC ku Moses Lake, Washington State, US, komwe ikasintha kwambiri zaka ziwiri. Mainjiniya ndi akatswiri a AeroTEC asintha Boeing 747-400 kuchokera ku ndege yamalonda yokhala ndi mipando 364 yonyamula anthu kupita ku testbed yapamwamba kwambiri yokhala ndi zida zambiri komanso machitidwe kuti athe kuyeza mozama momwe injini ikugwirira ntchito pakuwuluka.

Akamaliza, ndegeyo idzagwira ntchito limodzi ndi Rolls-Royce yoyeserera yowuluka yomwe ilipo, Boeing 747-200, yomwe yamaliza maulendo 285 oyesa mpaka pano.

Gareth Hedicker, Rolls-Royce, Director of Development and Experimental Engineering, anati: “Mfumukazi yakumwamba idzakhala mwala wamtengo wapatali pamapulogalamu athu apadziko lonse lapansi. Izi ndi ndalama zazikulu zomwe zidzakulitsa luso lathu loyesa kwambiri padziko lonse lapansi ndipo zitilola kupeza zambiri zoyesa ndege kuposa kale. Titanyamula anthu mamiliyoni ambiri m’ndege yokondedwa imeneyi kwa zaka 20, ndife okondwa kuti tidzaiyendetsanso m’tsogolo.”

Chris Snook, Executive Manager wa Engineering ku Qantas, adati: "Boeing 747 yakhala membala wofunikira komanso wokondedwa kwambiri pagulu la Qantas kwa zaka zambiri. Tagwiritsa ntchito pafupifupi mitundu yonse ndipo ngakhale ndizomvetsa chisoni kuwawona akupita, ma 747 akupanga njira ya Boeing 787 Dreamliners. OJU wavala kangaroo yowuluka monyadira kwa zaka zoposa 20 ndipo ndife okondwa kuti ali ndi moyo wautali patsogolo pake kuti athandize kuyesa ndikuthandizira kupanga injini za ndege za m’badwo wotsatira.”

Lee Human, Purezidenti wa AeroTEC ndi woyambitsa, adati: "Gulu la AeroTEC ndilonyadira kuyanjana ndi Rolls-Royce kuti asinthe, kumanga ndi kutumiza testbed yatsopanoyi. Malo opangira ma labotale oyendetsa ndegewa athandizira kupanga ndi kutsimikizira kwaukadaulo watsopano, wapamwamba kwambiri wamainjini opangidwa kuti uwonjezere magwiridwe antchito ndikuchepetsa kuwononga chilengedwe. Magulu athu a uinjiniya, kusintha, ndi mayeso ku Seattle ndi Moses Lake ali kale molimbika pakukonzekera kuti masomphenya a Rolls-Royce akwaniritsidwe. "

Rolls-Royce akuyika $70m (£56m) pogula ndi kukonzanso ndege za Qantas. Izi zikuphatikiza ndi ndalama zokwana £90m ku Testbed 80, kuyesa kwakukulu komanso kwanzeru kwambiri padziko lonse lapansi, komwe kukumangidwa ku Derby, UK, ndikukhazikitsidwa mu 2020.
