“Njengentliziyo” yesiphekepheke, i-injini idlala indima ephambili kuphuhliso lobugcisa be-aerospace. I-injini iyinkimbinkimbi kunye neyinkimbinkimbi yezixhobo zeqhinga eliphezulu, kodwa inkqubo yezinto eziphathekayo ezinokuhlangabezana neemfuno zokumelana nobushushu obuphezulu, ukusebenza okuzinzileyo kunye nobomi benkonzo ende ngexesha elifanayo lilinganiselwe kakhulu.
Kweli nqanaba, izixhobo zezakhiwo zobushushu obuphezulu obunje ngamagumbi okutsha kunye nee turbines zeenjini ze-aerospace zisalawulwa yi-superalloys. Emva kweminyaka engaphezu kwe-40 yophuhliso, ukumelana nobushushu bezinto zetsimbi ezimelwe yikristale enye ialloys kuye kwaphuculwa kakhulu, kodwa kusekude nobushushu bokutsha be-injini, kwaye kwisizukulwana esitsha seenjini, umsantsa uyanda ngokuthe ngcembe. .
Njengesixhobo esikhaphukhaphu esikhaphukhaphu kunye nesiphezulu sokusebenza, izinto ze-ceramic zisetyenziswa kakhulu kwindawo yobushushu obuphezulu. Ukusebenza kwayo okuphezulu kobushushu kuyenza ibe yenye yezixhobo zomgqatswa zokutshintsha izixhobo ze-superalloy kwiinjini ze-aerospace, ngakumbi kwiinjini eziphambili ze-injini.
Ngokutsho kwengxelo kwiwebhusayithi yeRussian "Izvestia" ngomhla we-18, iinjineli zaseRashiya ziye zaphuhlisa iteknoloji yokwenza iinjini ze-rocket nge-ceramics okokuqala ngqa emhlabeni. Iinjini ezinjalo ziyakwazi ukumelana nobushushu obuphezulu kuneenjini zetsimbi kwaye ngoko zisebenza kakuhle.
Ngenxa yokuba izinto ze-ceramic zincinci, oku kuya kuvumela i-rocket ukuba ibeke imithwalo eninzi kwi-orbit ngelixa isebenzisa amafutha amancinci. Abaphuhlisi bakholelwa ukuba ii-ceramics ngoku zingasetyenziselwa ukwenza ii-turbines zoomatshini abahlukeneyo bobushushu kwishishini lamandla.
“Senze isampulu yesampulu elingana nesundu,” utshilo umphathi weprojekthi ye-Ekipo ekuphuhliseni itekhnoloji yokudibanisa i-ceramic. "Akukho nto ingaqhelekanga ngale nto, kodwa akukho mntu ehlabathini owakha wakha into enje." Iinjini. Siye safunda indlela yokudibanisa izinto ezenziwe ngodongwe ukuze ingabonakali kakuhle, yaye amandla ayo angaphantsi komgangatho omnye.”
Ngokutsho kwabaphandi, ukuba i-injini ye-turbine yenziwe nge-ceramic, ukusebenza kwayo kuya kuba ngaphezu kwe-15% ephezulu kune-injini ye-alloy.
Uvavanyo lubonise ukuba iimveliso ze-ceramic ezenziwe ngobuchwephesha obutsha zinokuxhathisa ngokufanelekileyo into ebizwa ngokuba yi-thermal shock eyenzeka kwi-injini ye-rocket engamanzi, oko kukuthi, umahluko weqondo lobushushu ukusuka kwiqondo lobushushu ukuya kumaqondo angama-2,000 ngokukaCelsius kwisekondi enye enesiqingatha. Iingxelo zovavanyo zibonise ukuba iisampulu ze-injini zasinda ngaphezu kwe-120 ezothusayo zobushushu. Iingcali zibonisa ukuba ii-injini ze-ceramic azikho nje indawo. Inokuba luncedo kwisakhiwo soomatshini, njengamakhonkco episton aselwandle.
