Kuthamanga kwa ndege ndi nkhani yosangalatsa kwambiri osati kwa okonda ndege ndi akatswiri okha komanso kwa apaulendo achidwi. Kuthamanga kwa ndege zamalonda kumakhudza kwambiri zinthu zosiyanasiyana monga nthawi yoyenda, kuyendetsa bwino kwamafuta, mitengo ya matikiti, komanso zokumana nazo pakuthawira konse. Bukuli limapereka kuwunika mozama kwa liwiro la jet, kuphatikiza mbali zosiyanasiyana zokhudzana ndi liwiro la ndege zamalonda.
Kumvetsetsa Ndege Zamalonda
Ndege zamalonda ndizodabwitsa mwaukadaulo wamakono. Amapangidwa kuti azinyamula anthu mazanamazana paulendo wautali pa liwiro lalikulu. Liwiro la ndegezi—limene nthaŵi zambiri limatchedwa liŵiro la jet—ndilo chinthu chofunika kwambiri chimene chimakhudza kagwiridwe kake kake, kachitidwe kake, ndi chitetezo.
Kuthamanga kwa jeti kwa ndege zamalonda kumasiyana malinga ndi mtundu wa ndege, kapangidwe kake, ndi injini zake. Mwachitsanzo, ndege zopapatiza ngati Boeing 737 kapena Airbus A320 Nthawi zambiri amayenda pa liwiro lozungulira 0.78 mpaka 0.82 Mach, pomwe ndege zazikulu ngati Boeing 747 kapena Airbus A380 zimatha kuthamanga mpaka 0.85 mpaka 0.89 Mach.
Kuzindikira kuthamanga kwa ndege zamalonda si ntchito yolunjika. Zimaphatikizapo masamu ndi miyeso yovuta, poganizira zinthu zosiyanasiyana monga kutalika, liwiro la mphepo, ndi kukankhira.
Zinthu Zomwe Zimakhudza Kuthamanga kwa Jet
Kutalika:
Kutalika kumagwira ntchito yofunika kwambiri pakuthamanga kwa ndege zamalonda. Pamene ndege ikukwera kumalo okwera, mpweya umakhala wochepa kwambiri. Izi zikutanthauza kuti ndegeyo imakumana ndi zovuta zochepa, zomwe zimapangitsa kuti iziyenda pa liwiro lalikulu. Komanso, pamalo okwera kwambiri, kutentha kumakhala kotsika, zomwe zimathandiza kuti injini za ndegeyo zizigwira ntchito bwino komanso kuti zizitha kutulutsa mphamvu zambiri.
Komabe, kukwera ndege pamalo okwera kumakhalanso ndi mavuto. Mwachitsanzo, kutsika kwa mpweya kumatanthauza kuti mapiko a ndegeyo sakwera kwambiri, zomwe zimachititsa kuti ifulumire kwambiri kuti isauluke. Kuphatikiza apo, mpweya wochepa thupi pamalo okwera ukhoza kukhala ndi zotsatira zoyipa pa thanzi komanso chitonthozo cha okwera ndi ogwira nawo ntchito.
Mayendedwe a Mphepo/Liwiro
Mayendedwe amphepo ndi liwiro zimathandizanso kwambiri kuthamanga kwa ndege. Mphepo yamkuntho—mphepo yowomba molunjika kumene ikuuluka—ingathe kuchedwetsa ndege, kuonjezera nthaŵi yoyenda ndi kugwiritsira ntchito mafuta. Mosiyana ndi zimenezi, kamphepo kamphepo kakuwomba kolowera kumene ndege ikuuluka—ingathe kufulumizitsa ndege, kuchepetsa nthawi yoyenda ndiponso kugwiritsira ntchito mafuta.
Total Thrust
Total thrust imatanthauza mphamvu yophatikizana yopangidwa ndi injini za ndege kuti ipite patsogolo. Injini ya ndege ikamathamanga kwambiri, m'pamenenso imauluka mofulumira kwambiri. Komabe, kupanga mphamvu zambiri kumawononganso mafuta ambiri, zomwe zingakhudze mtengo waulendo wa pandege.
Kuyeza Liwiro la Ndege
Indicated Airspeed (IAS)
Indicated Airspeed (IAS) ndi liwiro lomwe limawonetsedwa pachowonetsa cha liwiro la ndege. Ndilo liwiro la ndege poyerekezera ndi mpweya wozungulira, woyezedwa pamalo pomwe ndegeyo ili. Komabe, IAS siyiganizira za liwiro la mphepo kapena komwe akupita, komanso siganizira kusintha kwa kachulukidwe ka mpweya chifukwa cha kusintha kwa mtunda kapena kutentha.
True Airspeed (TAS)
True Airspeed (TAS) ndi liwiro la ndege potengera momwe ikuwulukira. Mosiyana ndi IAS, TAS imaganizira za kusintha kwa kachulukidwe ka mpweya chifukwa cha kusintha kwa kutalika ndi kutentha. Komabe, monga IAS, TAS siganizira kuthamanga kwa mphepo kapena mayendedwe.
Groundspeed (GS)
Groundspeed (GS) ndi liwiro la ndege poyerekezera ndi pansi. Mosiyana ndi IAS ndi TAS, GS imaganizira momwe mphepo imayendera komanso mayendedwe ake. GS ndi liwiro lomwe okwera nthawi zambiri amatchula akamalankhula za kuthamanga kwa ndege.
Calibrated Airspeed (CAS)
Calibrated Airspeed (CAS) ndi IAS yokonzedwa chifukwa cha zolakwika za zida ndi kusintha kwa kuthamanga kwa mpweya chifukwa cha kusintha kwa msinkhu ndi kutentha.
Machine
Mach ndi muyeso wa liwiro loyerekeza ndi liwiro la mawu. Ndege yomwe ikuuluka pa Mach 1 ikuyenda mothamanga kwambiri. Ndege zamalonda nthawi zambiri zimayenda mothamanga mozungulira Mach 0.8 mpaka Mach 0.9.
Liwiro Liwiro la Ndege Zotchuka
Boeing 747
Boeing 747, yomwe imadziwikanso kuti "Queen of the Skies," ndi ndege yamagulu ambiri yomwe imatha kunyamula anthu mazana ambiri paulendo wautali. Ili ndi liwiro lalikulu loyenda mozungulira Mach 0.85.
Boeing 737
Boeing 737 ndi ndege yopapatiza yomwe imagwiritsidwa ntchito nthawi zambiri pamaulendo apanyumba amfupi. Ili ndi liwiro lalikulu loyenda pafupifupi Mach 0.78.
Airbus A380
Airbus A380 ndiye ndege yayikulu kwambiri padziko lonse lapansi yonyamula anthu. Ndi ndege yapawiri, yotambasuka yomwe imatha kunyamula anthu opitilira 800. Kuthamanga kwake kwakukulu kuli pafupifupi Mach 0.85.
Mayendedwe Osiyanasiyana Panthawi Yakuuluka
Nyamuka
Ponyamuka, ndege zamalonda zimafika pa liwiro la pafupifupi 150 mpaka 180 mfundo (pafupifupi mailosi 170 mpaka 207 pa ola).
Kuthamanga
Pamene akuyenda pamtunda wapamwamba, ndege zamalonda nthawi zambiri zimayenda mothamanga mozungulira Mach 0.8 mpaka Mach 0.9 (pafupifupi 600 mpaka 680 mailosi pa ola).
Tikufika
Pakutera, ndege zamalonda zimatsika pang'onopang'ono mpaka liwiro la 140 mpaka 160 knots (pafupifupi 161 mpaka 184 mailosi pa ola).
Mayendedwe a Mitundu Yosiyanasiyana ya Ndege
Jets Private
Majeti apayekha nthawi zambiri amakhala othamanga kuposa ndege zamalonda. Amatha kuwulukira pamalo okwera, pomwe mpweya wake ndi wocheperako ndipo umapereka mphamvu zochepa, zomwe zimawathandiza kuti azithamanga kwambiri.
Ndege Zankhondo
Ndege zankhondo zimapangidwira kuti zizithamanga komanso zothamanga. Mwachitsanzo, ma jets omenyera nkhondo amatha kuthamanga kwambiri pa Mach 2.
Makina Amodzi
Ndege za injini imodzi nthawi zambiri zimakhala zochedwa kuposa ndege za injini zambiri. Amagwiritsidwa ntchito pamaulendo apamtunda afupiafupi pamtunda wotsika.
Zotsatira za Ndege ya Supersonic
Kuuluka kwapamwamba kwambiri—kuuluka mofulumira kuposa liŵiro la phokoso—kungathe kusintha maulendo apandege pochepetsa kwambiri nthaŵi yoyenda. Komabe, zimabweretsanso zovuta monga kuchuluka kwamafuta, kuwononga phokoso, komanso kupanga ma sonic booms.
Ntchito Yogwira Ntchito Mwachangu
Kukwera mtengo ndikofunikira kwambiri pakuyendetsa ndege zamalonda. Oyendetsa ndege amayesetsa kuyendetsa ndege zawo motsika mtengo momwe angathere kuti mitengo ya matikiti ikhale yotsika komanso kuti apeze phindu. Choncho, ayenera kulinganiza chikhumbo cha kuthamanga kwa ndege ndi kufunikira kosunga mafuta ndi kuchepetsa ndalama zogwiritsira ntchito.
Tsogolo la Kuthamanga kwa Jet
Tsogolo la liwiro la jeti likuyenda bwino, kupita patsogolo kwaukadaulo ndi uinjiniya komwe kumapangitsa kuti ndege zamalonda ziziuluka mwachangu komanso mwaluso. Komabe, kukwaniritsa kupititsa patsogolo kumeneku kudzafunika kuthana ndi zovuta zazikulu, kuphatikizapo kuchepetsa kuwonongeka kwa chilengedwe cha kayendetsedwe ka ndege komanso kuonetsetsa chitetezo ndi chitonthozo cha okwera.
Pomaliza, kuthamanga kwa jet ndi mutu wosangalatsa komanso wovuta. Zimatheka chifukwa cha zinthu zosiyanasiyana ndipo zimathandiza kwambiri kuti maulendo apandege ayende bwino, atetezeke komanso kuti asamawononge ndalama zambiri. Pamene luso lazopangapanga likupita patsogolo, tingayembekezere tsogolo la maulendo apandege achangu, aluso, ndi okhazikika.
Kutsiliza
Kumvetsetsa liwiro la jeti sikungodziwa kuti ndege imauluka mwachangu bwanji. Ndikonso kumvetsetsa zinthu zosiyanasiyana zomwe zimakhudza kuthamanga kumeneku komanso momwe zimasewererana kuti mudziwe liwiro loyenera paulendo uliwonse. Pamene luso lazopangapanga likupita patsogolo, tingayembekezere kuwona kusintha kwa liwiro la jeti, zomwe zingapangitse maulendo apandege ofulumira komanso abwino m'tsogolomu.
