Ngo-9:56 ngomhlaka-16 Ephreli 2022, ngesikhathi saseBeijing, i-Shenzhou 13 manned spacecraft return capsule yafika ngempumelelo eDongfeng Landing Site, futhi umsebenzi wokundiza weShenzhou 13 manned waba yimpumelelo enkulu.

Ukwethulwa kwesikhala, ukushiswa kukaphethiloli, ukulungiswa kwesimo sesathelayithi kanye nezinye izixhumanisi eziningi ezibalulekile azihlukaniseki ngosizo lwegesi. Izinjini zesizukulwane esisha sezimoto zokwethulwa ezweni lami zisebenzisa kakhulu uketshezi.i-hydrogen, uketsheziumoya-mpilokanye ne-parafini njengophethiloli.I-Xenonunesibopho sokulungisa ukuma kanye nokushintsha imijikelezo yamasathelayithi emkhathini.I-nitrogenisetshenziselwa ukuhlola ukuqina komoya kwamatangi e-rocket propellant, izinhlelo zenjini, njll. Izingxenye ze-valve zomoya zingasebenzisai-nitrogennjengomthombo wamandla. Kwezinye izingxenye zevalvu yomoya ezisebenza emazingeni okushisa e-hydrogen ewuketshezi,i-heliumKusetshenziswa umsebenzi. I-nitrogen exutshwe nomhwamuko we-propellant ayinayo ingozi yokushisa nokuqhuma, ayinawo umthelela omubi ohlelweni lwe-propellant, futhi iyigesi yokuhlanza engabizi futhi efanelekile. Ezinjinini zerokhethi ze-hydrogen-oxygen eziwuketshezi, ngaphansi kwezimo ezithile zokukhanya kwelanga, kumele ipheshulwe nge-helium.

Igesi inikeza amandla anele erokhethi (isigaba sokundiza)

Amarokhethi okuqala ayesetshenziswa njengezikhali noma ukwenza iziqhumane. Ngokwesimiso sesenzo namandla okusabela, irokhethi lingakhiqiza amandla ohlangothini olulodwa - ukusunduza. Ukuze kukhiqizwe ukusunduza okudingekayo irokhethi, kusetshenziswa ukuqhuma okulawulwayo okuvela ekusabeleni kwamakhemikhali okunamandla phakathi kukaphethiloli kanye ne-oxidizer. Igesi ekhulayo evela ekuqhumeni ikhishwa ngemuva kwerokhethi nge-jet port. I-jet port iqondisa igesi yokushisa okuphezulu kanye nengcindezi ephezulu ekhiqizwa ukusha iye emsinga womoya, ophuma ngemuva ngesivinini se-hypersonic (isivinini somsindo esiphindwe kaningana).

Igesi inikeza ukwesekwa kwabahamba ngezinkanyezi ukuze baphefumulele emkhathini

Amaphrojekthi okundiza emkhathini anabantu anezidingo eziqinile kakhulu kumagesi asetshenziswa osomkhathi, adinga ukuhlanzeka okuphezulu.umoya-mpilokanye nezingxube ze-nitrogen. Ikhwalithi yegesi ithinta ngqo imiphumela yokukhishwa kwerokhethi kanye nesimo somzimba sabashayeli bezindiza.

Amandla kagesi 'okuhamba' phakathi kwezinkanyezi

Kungani kufanele usebenzisei-xenonnjenge-propellant?I-Xenoninesisindo esikhulu se-athomu futhi i-ionized kalula, futhi ayinayo i-radioactive, ngakho-ke ifaneleka kakhulu ukusetshenziswa njenge-reactant yama-ion thrusters. Ubunzima be-athomu bubalulekile futhi, okusho ukuthi uma isheshiswa ngesivinini esifanayo, i-nucleus enkulu kakhulu iba nomfutho owengeziwe, ngakho-ke uma ikhishwa, amandla okusabela amaningi iwanikeza i-thruster. Uma i-thruster inkulu, kulapho i-thruster iba nkulu khona.
