NASA ei ole siiski veel avaldanud, kui palju heli lennuk helibarj\u00e4\u00e4ri \u00fcletades tekitas. Lisaks lendas katse ajal X-59 j\u00e4rel F-15 h\u00e4vituslennuk, mille m\u00fcra varjas X-59 heli. Hiljem sel aastal on kavas t\u00e4iendavad katsed.<\/p>\n
Maailma esimene \u00fclehelikiirusel lend toimus 1947. aastal, kui Ameerika \u00dchendriikide \u00f5huv\u00e4e piloot Charles Yeager lendas Bell X-1 lennukiga \u00fcle Kalifornia Mojave k\u00f5rbe. Yeager kiirendas lennuki kiiruseni 1,06 Machi, avades lennunduses uued v\u00f5imalused \u2013 kuid mitte tingimata kommertslennunduses.<\/p>\n
\u201eMe naljatame alati, et X-1 murdis helibarj\u00e4\u00e4ri ja n\u00fc\u00fcd \u00fcritame seda parandada,\u201c \u00fctles 2023. aastal BBC-le NASA Low Boom Flight Demonstrator projekti juht Catherine Bahm, kes juhib X-59 arendust\u00f6\u00f6d.<\/p>\n
Kui lennuk liigub edasi, surub ta enda ees olevaid \u00f5humolekule k\u00f5rvale. See paneb \u00f5hu vibreerima, tekitades helilained. Kui \u00f5hus\u00f5iduk \u00fcletab helibarj\u00e4\u00e4ri, surutakse \u00f5hur\u00f5hulained selle taga kokku ja moodustavad l\u00f6\u00f6klaine, mis vabastab energia k\u00f5rvulukustava paugu kujul.<\/p>\n

See heli v\u00f5ib \u00fcletada 110 detsibelli \u2013 see on sama vali kui t\u00e4isv\u00f5imsusel t\u00f6\u00f6tav terasetehas ja \u00fcletab k\u00fcnnise, millest alates enamik inimesi tunneb k\u00f5rvavalu. Need paugud on isegi kahjustanud vara, n\u00e4iteks purustades aknaid ja v\u00e4hemalt \u00fchel juhul akvaariume. Sel p\u00f5hjusel keelas F\u00f6deraalne Lennuamet 1973. aastal mittes\u00f5jalistel lennukitel helibarj\u00e4\u00e4ri \u00fcletamise USA territooriumi kohal.<\/p>\n
Kuigi Air France\u2019i ja British Airwaysi Concorde, mis lendas aastatel 1976\u20132003 Londoni v\u00f5i Pariisi ja New Yorgi vahel, oli maailma esimene kommertslend \u00fclehelikiirusel, lubati seda lennukit kasutada ainult seet\u00f5ttu, et see \u00fcletas helibarj\u00e4\u00e4ri Atlandi ookeani kohal. L\u00f5puks v\u00f5eti see kasutuselt \u00e4ra p\u00e4rast seda, kui \u00fcks lennuk Prantsusmaa Charles de Gaulle\u2019i lennujaamast \u00f5hkut\u00f5usul alla kukkus, mille tagaj\u00e4rjel hukkusid k\u00f5ik pardal olnud inimesed.<\/p>\n
X-59 \u00fclikiire ja kitsa nina eesm\u00e4rk on minimeerida selle tekitatud l\u00f6\u00f6klaine m\u00f5ju. Lennuk, mis tekitab vaiksema helil\u00f6\u00f6gi, v\u00f5imaldaks helikiirusest kiiremaid kommertslende maismaa kohal. See t\u00e4hendaks, et lennukiga saaks reisida umbes poole kiiremini. Siiski ei ole NASA veel avaldanud teavet selle kohta, kui palju detsibelle X-59 esimene helipauk tekitas.<\/p>\n
Lisaks kommertsv\u00f5imalustele on vaiksemal \u00fclikiirel lennul ka ilmsed s\u00f5jalised rakendused, kuna see muudab salajased missioonid m\u00e4rkimisv\u00e4\u00e4rselt m\u00e4rkamatumaks. NASA kavatseb l\u00e4hin\u00e4dalatel l\u00e4bi viia X-59 esimese missioonitingimustes testlennu, mille k\u00e4igus saavutatakse kiirus 1,4 Machi umbes 17 000 m k\u00f5rgusel.<\/p>\n
