YSupersonic vs Hypersonic
Tus nqi ntawm cov khoom mus nrawm dua li qhov nrawm ntawm lub suab yog qhia nyob rau hauv cov ntsiab lus ntawm supersonic thiab hypersonic speeds. Xws li ceev yog ntsuas raws li Mach. Mach tus lej txhais tau tias yog qhov piv ntawm qhov nrawm ntawm lub dav hlau mus rau qhov nrawm ntawm lub suab. Supersonic thiab Hypersonic yog ob hom tseem ceeb ntawm kev ya davhlau. Hauv cov lus tshawb fawb, lawv zoo dua lub npe hu ua kev tswj hwm ntawm kev ya davhlau.
Supersonic ceev
Supersonic ceev yog tus nqi ntawm kev mus los uas tshaj qhov ceev ntawm lub suab, kuj hu ua Mach 1 ceev. Txij li qhov ceev ntawm lub suab nyob ntawm qhov kub thiab txias ntawm huab cua, supersonic ceev kuj txawv nrog qhov siab hloov pauv. Hauv dej ntawm chav tsev kub, nws yog ntau dua 1440 m / s, thaum nyob rau hauv cov khib nyiab nws tseem ntau dua. Ib qho piv txwv ntawm supersonic yog, ib lub mos txwv raug rho tawm ntawm rab phom. Fighter dav hlau thiab chaw shuttle kuj ya ntawm cov ceev no. Concorde yog tib tus neeg nrog caij dav hlau mus ncig ntawm qhov nrawm. Nws tau siv nws lub davhlau kawg hauv xyoo 2003 thiab nws tsis siv tam sim no. Lub sij hawm sonic boom yog txuam nrog cov speeds. Thaum lub dav hlau ya ntawm qhov ceev no, ib tug neeg hauv av hnov lub suab nrov heev, uas yog hu ua sonic boom. Sonic boom yog tsim los ntawm kev txav ntawm huab cua molecules nyob rau hauv lub zog loj heev.
Hypersonic ceev
Hypersonic speeds sib haum mus rau supersonic ceev heev. Lawv yeej yog Mach 5 speeds los yog tsib npaug ntawm lub suab ceev. Qhov ceev ntawm lub dav hlau hypersonic yog nyob ib ncig ntawm 3000 mais ib teev. Cov kev ceev no dua ntawm peb hom, qis hypersonic, hypersonic thiab siab hypersonic. X-15 yog tib lub dav hlau uas muaj peev xwm ya tau ntawm qhov nrawm nrawm, i.e. ntawm Mach 6. Thaum lub sij hawm nws rov nkag, qhov chaw shuttle kuj tau txais xws li ceev. Qhov kev ncua deb ntawm kev poob siab yoj, tsim los ntawm lub dav hlau hypersonic thiab lub dav hlau me dua nyob rau hauv cov ntaub ntawv ntawm supersonic aircraft.
In luv:
YSupersonic vs Hypersonic
♦ Supersonic yog Mach 1 nrawm thaum hypersonic yog Mach 5 ceev.
♦ Supersonic ceev yog siab dua qhov ceev ntawm lub suab thaum hypersonic yog 5 npaug ntawm lub suab nrawm.
♦ Concorde yog tib lub dav hlau supersonic neeg caij dav hlau thaum tsis muaj tus neeg caij dav hlau hypersonic.
